OPINION & ORDER
KENNETH M. KARAS, District Judge:
Pro se Plaintiff Ricky Kamdem-Ouaffo (“Plaintiff’) bring this Second Amended Complaint (“SAC”) against Pepsico, Inc. (“PepsiCo”), Dr. Peter S. Given, Jr. (“Dr. Given”), Dr. Naijie Zhang (“Dr. Zhang”), ScentSational Technologies LLC (“ScentSational”), and Steven M. Landau (“Landau”) (collectively, “Defendants”), asserting unenforceable contract, unjust enrichment, constructive trust, correction of inventorship, and defamation. (Dkt. No. 52). Before the Court are two Motions to Dismiss Plaintiffs Second Amended Complaint (collectively, “Motions”), one on behalf of ScentSational and Landau (“ScentSational Defendants”) and one on behalf of PepsiCo, Dr. Given, and Dr. Zhang (“PepsiCo Defendants”). (Dkt. Nos. 72, 75.) For the following reasons, Defendants’ Motions are granted, and Plaintiffs Second Amended Complaint is dismissed with prejudice.
I. Background
A. Factual Background
The factual allegations that follow are derived from Plaintiffs Second Amended Complaint, which the Court assumes to be true for the purpose of deciding the instant Motions.
Plaintiff, a resident of New Brunswick, New Jersey, “has many years of experience in the research and development, manufacturing, analysis[,] and application of flavors and aromas.” (Pl.’s Second Am. Compl. (“SAC”) ¶ 8 (Dkt. No. 52).) From July 14, 2008 to September 28, 2009, Plaintiff worked under contract as a “Food Scientist at ... PepsiCo’s Research and Development facility in Valhalla, New York.” (Id. ¶ 22.) In that capacity, Plaintiff was tasked with “providing] leadership and strategy for developing [and] evaluating commercially viable Aroma Technology Delivery System[s] applicable to PepsiCo’s commercial items.” (Id. ¶ 27.)
Prior to beginning his work at PepsiCo, Plaintiff signed a “Staffing Supplier Employee Agreement Regarding Confidentiality and Intellectual Property” (“Agreement”) with PepsiCo through Subex Technologies, Inc. (“Subex”) “as the [staffing [a]gency.” (Id. ¶ 23 (internal quotation marks omitted).) Plaintiff signed the Agreement on July 9, 2008, at which time Subex managers explained that, pursuant to the Agreement, “Plaintiff in principle consented to assigning his future intellectual property to PepsiCo for commercial use in exchange [for] payment to be made to ... Plaintiff in the future.” (Id. ¶¶ 23-24.) Plaintiff alleges there was also “[a] common understanding” that should intellectual property created by Plaintiff during the period of his contract “be found patentable,” PepsiCo would “credit” Plaintiff as the inventor. (Id. ¶ 25.)
During the period of his employment as a “Food Scientist[,]... Plaintiff pioneered, conceptualized, designed, demonstrated, proved, executed, and implemented aroma concepts, technologies, and techniques ... that none of [PepsiCo’s] employees [had] [557]*557been able to do prior to ... Plaintiffs work.” (Id. ¶ 29.) Plaintiff received $82,142 in compensation for his work, or $56,384 in take-home pay, which amounted to only a percentage of the $133,007.50 Plaintiff alleges he is owed under an unsigned purchase order. (Id. ¶¶ 52-53, 186-87.)1
At some point prior to or on September 16, 2009, PepsiCo Defendants, at the direction of PepsiCo senior managers, “expunged ... Plaintiffs name from” intellectual property Plaintiff created during his employment. (Id. ¶¶ 32, 34.) In subsequent patent applications, PepsiCo credited these inventions to Dr. Given and Dr. Zhang, though allegedly neither “contribute[d] to the creation and/or inventions of’ that intellectual property. (Id. ¶ 32.) Specifically, Plaintiff alleges that Dr. Given provided “no intellectual input or supervision” when “Plaintiff created and conceptualized his inventions and reduced them to practice,” and “Dr. Zhang was not even an employee of PepsiCo” during that time period. (Id. ¶ 33.)
Plaintiff further alleges that the removal of his name from the intellectual property was part of a coordinated attempt by Pep-siCo to distance itself from Plaintiff. On the same day that PepsiCo managers removed Plaintiffs name certain intellectual property, Dr. Given allegedly sent an email to his colleagues that said: “ ‘Another hitch — [Plaintiffs] contract is terminating Oct[ober] 5, and he’ll be informed this week ... more drama! Please do not distribute this info, but [it] may impact our decision on inventorship.’ ” (Id. ¶ 8 (italics omitted).)2 Dr. Zhang allegedly sent a similar email, stating that “ ‘[Plaintiff] is not [the] inventor. He is just involved in the project ....’” (Id. ¶9 (third alteration in original) (italics omitted).) Plaintiff contends that around this time an unnamed PepsiCo employee secretly entered a notation in Plaintiffs personnel file reading “Dept, not satisfied,” which erroneously suggested Plaintiffs work had been unsatisfactory. (Id. ¶ 38 (italics omitted).)
On or around September 23, 2009, five days before the expiration of Plaintiffs contract, PepsiCo Human Resources Manager Aida Costello allegedly told Plaintiff that he was “ ‘culturally unfit’ ” for employment, “being a black male [with] an opinion on scientific matters that was contrary to that of his peers of [another] skin color,” and that he “needed to be ‘coached.’ ” (Id. ¶ 64-66 (alteration omitted).) Plaintiff likewise alleges that Pepsi-Co’s decision not to credit Plaintiff for his claimed inventions stemmed from “raw racism ... directed against people,” like Plaintiff, “who are of the genetics ... and appearance that [Defendants don’t like.” (Id. ¶ 71.)
On September 28, 2009, Plaintiffs work assignment contract expired and was not renewed. (Id. ¶¶ 35-36.)3 At that time, Plaintiff sent a letter to PepsiCo in which he made an “authorship claim on any cur[558]*558rent or future work resulting in ... flavor encapsulates or ... aroma delivery systems because [he] single-handedly demonstrated the need for such when no one at PepsiCo had [them] in mind ...(Id. ¶ 62 (first and second alterations in original) (emphasis and internal quotation marks omitted).) A few months later, on December 18, 2009, PepsiCo Defendants allegedly wrote in a letter to the United States government that “Plaintiff was not able to do work, and was not creative ... by comparison to his counter parts [sic] of ... other skin color[s].” (Id. ¶ 67.) According to the SAC, PepsiCo also represented that Plaintiff went “to work at [its] facilities just for the pretense and opportunity of predatory sexual intercourse with women of ... other [races].” (Id. ¶ 253; see also id. ¶¶ 68, 274, 311.)
Thereafter, PepsiCo filed for five patents with the United States Patent and Trademark Office (“USPTO”) based on the intellectual property at issue, one of which, a patent application for “Releasable Entrapment of Aroma Using Polymeric Matrix,” was granted on July 2, 2013 (US Patent No. 8,474,637 B2). (See id. ¶¶ 41, 47, 60.)4 In connection with the patent applications, Dr. Given and Dr. Zhang allegedly each signed or cosigned “Inventor’s Oath[s] or Declaration^],” including a “Joint Inventor’s Declaration,” for the granted patent. (Id. ¶¶ 44-48.) Dr. Given and Dr. Zhang also allegedly executed and filed an assignment of the relevant intellectual property to PepsiCo. (Id. ¶¶ 49-50.)
On October 11, 2012, Plaintiff submitted a request to PepsiCo, asking that it amend the relevant “patent applications and patents thereof from which [it] ... removed ...' Plaintiffs name” to credit him as the inventor. (Id. ¶ 55; see also id. ¶ 56.) Pepsi-Co did not reply to this request, nor did it “make the amendment and correction of inventorship requested.” (Id. ¶ 59.) Nonetheless, Plaintiff alleges that he is the “true inventor” of both the patented property and the property described in the four pending patent applications. (Id. ¶ 93; see also id. ¶¶ 60,107-08.)
B. Procedural History
Plaintiff commenced the instant Action on January 31, 2014 against PepsiCo, Dr. Given, and Dr. Zhang, alleging six causes of action arising out of his temporary work assignment for PepsiCo. (Dkt. No. 1.) On March 14, 2014, the same day that PepsiCo Defendants first requested a pre-motion conference, (Dkt. No. 8), Plaintiff filed his First Amended Complaint (“FAC”), alleging thirteen causes of action, specifically “breach of intellectual property agreement,” “wrongful appropriation of plaintiffs intellectual property,” “fraudulent obtaining of signature,” “correction of inventorship,” “unjust enrichment,” “the necessity of constructive trusts,” a “request for subpoenas,” three causes of action relating to alleged false statements made to the USPTO, and three causes of action relating to other alleged criminal conduct. (Dkt. No. 9.) Pursuant to a scheduling order set at the pre-motion conference held on May 15, 2014, (Dkt. No. 31), PepsiCo Defendants filed their Motion To Dismiss and Memorandum of Law on June 6, 2014, (Dkt. Nos. 34-35) as well as an associated Declaration on June 9, 2014, (Dkt. No. 37). On July 9, 2014, Plaintiff submitted a “Notice of Counterclaim ... in Support of the Denial of the Defendants’ Motion to Dismiss,” in addition to an Affidavit and Memorandum of [559]*559Law in support of that submission. (Dkt. Nos. 41-43.) Along with these papers, Plaintiff submitted a “Proposed Amended Complaint” that added ScentSational and Landau as Defendants while alleging virtually identical conduct as that laid out in his First Amended Complaint (“Revised FAC”). (Pl.’s Mem. of Law in Supp. of Pl.’s Countercl. and in Supp. of Denial of Defs.’ Mot. To Dismiss Ex. 1 (Dkt. No. 43).)5 PepsiCo Defendants filed their Reply on August 8, 2014. (Dkt. No. 46.)
Without accepting the Revised FAC for filing but nonetheless considering its allegations, the Court dismissed Plaintiffs FAC without prejudice on March 9, 2015. (Dkt. No. 50.)6 In that Opinion & Order, this Court granted Plaintiff leave to file a Second Amended Complaint “that specifically addresses the deficiencies identified” as well as to “renew his request to join [ScentSational] and [Landau] and file claims against them.” Kamdem-Ouaffo v. Pepsico, Inc., No. 14-CV-227, 2015 WL 1011816, at *18 (S.D.N.Y. Mar. 9, 2015).
On March 25, 2015, Plaintiff filed his SAC, alleging five causes of action arising out of his temporary work assignment at PepsiCo and joining ScentSational and Landau as additional Defendants. (Dkt. No; 52.) Pursuant to a briefing schedule set by the Court on May 11, 2015, (Dkt. No. 71), ScentSational Defendants filed their Motion to Dismiss Plaintiffs Second Amended Complaint and supporting papers on June 15, 2015. (Dkt. Nos. 72-74.) Also on that date PepsiCo Defendants filed their separate Motion to Dismiss Plaintiffs Second Amended Complaint and supporting papers. (Dkt. Nos. 75-77.) On July 21, 2015, Plaintiff filed a “Memorandum of Law in Support of the Denial of the Pepsi-Co Defendants’ Motion to Dismiss,” (Dkt. No. 86), along with a Motion to Intervene and/or Consolidate, (Dkt. Nos. 84 — 85).7 Without the Court’s leave, he also submitted a Proposed Second Amended Complaint With More Definitive Statements (“Revised SAC”). (Mot. to Am. Compl. Ex. 1-2 (Dkt. No. 81).)8 Defendants submitted [560]*560separate Reply Memoranda of Law in Support of their own Motions to Dismiss on July 29, 2015, (Dkt. Nos. 87- 88), and PepsiCo Defendants filed their Memorandum of Law in Opposition to Plaintiffs Motion to Intervene and/or Consolidate, (Dkt. No. 89). In a separate opinion, the Court has denied Plaintiffs Motion to Intervene and/or Consolidate.
II. Discussion
A. Standard of Review
“While a complaint attacked by a Rule 12(b)(6) motion to dismiss does not need detailed factual allegations, a plaintiffs obligation to provide the grounds of his entitlement to relief requires more than labels and conclusions, and a formulaic recitation of the elements of a cause of action will not do.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007) (alterations, citations, and internal quotation marks omitted). Indeed, Rule 8 of the Federal Rules of Civil Procedure “demands more than an unadorned, the-defendant-unlawfully-harmed-me accusation.” Ashcroft v. Iqbal, 556 U.S. 662, 678, 129 S.Ct. 1937, 173 L.Ed.2d 868 (2009). “Nor does a complaint suffice if it tenders naked assertions devoid of further factual [561]*561enhancement.” Id. (alterations and internal quotation marks omitted). Instead, a complaint’s “[f]actual allegations must be enough to raise a right to relief above the speculative level.” Twombly, 550 U.S. at 555, 127 S.Ct. 1955. Although “once a claim has been stated adequately, it may be supported by showing any set of facts consistent with the allegations in the complaint,” id. at 563, 127 S.Ct. 1955, and a plaintiff need allege “only enough facts to state a claim to relief that is plausible on its face,” id. at 570, 127 S.Ct. 1955, if a plaintiff has not “nudged [his or her] claim[ ] across the line from conceivable to plausible, the[] complaint must be dismissed,” id.; see also Iqbal, 556 U.S. at 679, 129 S.Ct. 1937 (“Determining whether a complaint states a plausible claim for relief will ... be a context-specific task that requires the reviewing court to draw on its judicial experience and common sense. But where the well-pleaded facts do not permit the court to infer more than the mere possibility of misconduct, the complaint has alleged— but it has not ‘show[n]’ — ‘that the pleader is entitled to relief.’ ” (second alteration in original) (citation omitted) (quoting Fed. R. Civ. P. 8(a)(2))); id. at 678-79, 129 S.Ct. 1937 (“Rule 8 marks a notable and generous departure from the hyper-technical, code-pleading regime of a prior era, but it does not unlock the doors of discovery for a plaintiff armed with nothing more than conclusions.”).
“[W]hen ruling on a defendant’s motion to dismiss, a judge must accept as true all of the factual allegations contained in the complaint.” Erickson v. Pardus, 551 U.S. 89, 94, 127 S.Ct. 2197, 167 L.Ed.2d 1081 (2007); see also Nielsen v. Rabin, 746 F.3d 58, 62 (2d Cir.2014) (“In addressing the sufficiency of a complaint we accept as true all factual allegations ....” (internal quotation marks omitted)); Aegis Ins. Servs., Inc. v. 7 World Trade Co., 737 F.3d 166, 176 (2d Cir.2013) (“In reviewing a dismissal pursuant to Rule 12(b)(6), we ... accept all factual allegations in the complaint as true .... ” (alterations and internal quotation marks omitted)). Further, “[flor the purpose of resolving [a] motion to dismiss, the Court .., draw[s] all reasonable inferences in favor of the plaintiff.” Daniel v. T & M Prat. Res„ Inc., 992 F.Supp,2d 302, 304 n. 1 (S.D.N.Y.2014) (citing Koch v. Christie’s Int’l PLC, 699 F.3d 141, 145 (2d Cir.2012)). Where, as here, a complaint was filed pro se, it must be construed liberally with “special solicitude” and interpreted to raise the strongest claims that it suggests. Hill v. Curcione, 657 F.3d 116, 122 (2d Cir.2011) (internal quotation marks omitted).
Additionally, “[i]n ruling on a 12(b)(6) motion, ... a court may consider the complaint!,] • • • any written instrument attached to the complaint as an exhibit[,] or any statements or documents incorporated in it by reference,” as well as “matters of which judicial notice may be taken, and documents either in [the] plaintiffs’ possession or of which [the] plaintiffs had knowledge and relied on in bringing suit.” Kalyanaram v. Am. Ass’n of Univ. Professors at N.Y. Inst. of Tech., Inc., 742 F.3d 42, 44 n. 1 (2d Cir.2014) (alteration and internal quotation marks omitted); see also Leonard F. v. Isr. Disc. Bank of N.Y., 199 F.3d 99, 107 (2d Cir.1999) (“In adjudicating a Rule 12(b)(6) motion, a district court must confine its consideration to facts stated on the face of the complaint, in documents appended to the complaint or incorporated in the complaint by reference, and to matters of which judicial notice may be taken.” (internal quotation marks omitted)); Hendrix v. City of N.Y., No. 12-CV-5011, 2013 WL 6835168, at *2 (E.D.N.Y. Dec. 20, 2013) (same).
B. Unenforceable Contract, Unjust Enrichment, and Constructive Trust Claims
As in the FAC, Plaintiff alleges against PepsiCo Defendants several causes action [562]*562arising out of the Agreement.9 The Court, once again, finds that these allegations of unenforceable contract, unjust enrichment, and constructive trust fail to state a claim upon which relief may be granted.
1. Res Judicata
First and foremost, Plaintiffs claims of unenforceable contract, unjust enrichment, and constructive trust, all of which relate to the Agreement, are barred by res judicata because they were or could have been raised by Plaintiff in a prior proceeding. Under the federal rules of res judicata, a subsequent lawsuit will be barred where a party can show: (1) an adjudication on the merits in the previous action; (2) that the previous lawsuit involved the same parties, or those in privity with them; and (3) that the claims asserted in the subsequent suit were raised, or could have been raised, in the prior proceeding. See Monahan v. N.Y.C. Dep’t of Corr., 214 F.3d 275, 285 (2d Cir.2000).10 “The rationale underlying this principle is that a party who has been given a full and fair opportunity to litigate a claim should not be allowed to do so again.” In re Hunter, 4 N.Y.3d 260, 794 N.Y.S.2d 286, 827 N.E.2d 269, 274 (2005).
In September 2010, Plaintiff filed a lawsuit in the New York Supreme Court, alleging a number of causes of action against PepsiCo. See Kamdem-Ouaffo v. PepsiCo, Inc., No. 22625/2010 (N.Y.Sup.Ct. 2010); see also Kamdem-Ouaffo, 2015 WL 1011816, at *4 n. 9 (discussing this state court action). Most relevant here, Plaintiffs complaint alleged that PepsiCo breached the employment contract by terminating Plaintiff prior to the contract’s end date and that PepsiCo violated New York’s Whistle Blower statute by terminating him before the contract expired and by refusing to consider him for a permanent position. (See Tempesta Decl. Ex. 4 (“N.Y. Judgment”) 3.)11 Plaintiff not only [563]*563readily acknowledges this prior proceeding, (see, e.g., SAC ¶¶ 38, 71 n.l, 112), but also notes that “[t]he said [summary judgment] motion at the Supreme Court of the State of New York was granted in favor of PepsiCo,” (id. ¶ 144). In fact, even prior to the state court’s ruling on PepsiCo’s motion for summary judgment, Plaintiff agreed to the dismissal of his breach of contract claims. (See N.Y. Judgment 13.)12 With regard to Plaintiffs Whistle Blower allegations, PepsiCo argued, inter alia, that these claims should be dismissed because Plaintiffs termination resulted from the expiration of the temporary employment contract and not as a retaliatory measure by the defendant. (See id. (noting Pepsi-Co’s argument that “the expiration of that agreement was not an adverse change”).) On July 8, 2013, the state court dismissed these claims, (see id. at 40), concluding “there is no triable issue of fact that [Pep-siCo] did not engage in retaliation based on its failure to either renew Plaintiffs contract or offer Plaintiff another permanent position as a result of Plaintiffs Whistle Blower activity,” (see id. at 32).
In addition to involving the same parties and thereby satisfying the second element of res judicata, the prior proceeding also satisfies the first, as the state court evaluated the merits of Plaintiffs contract claims against PepsiCo and found his allegations lacking. See Kamdem-Ouaffo v. Pepsico, Inc., 133 A.D.3d 825,21 N.Y.S.3d 150, 154 (2015) (affirming that PepsiCo “established its prima facie entitlement to judgment as a matter of law dismissing the remaining causes of action to recover damages for[, inter alia,] breach of contract”).13 As to the third prong of the test, in considering whether Plaintiffs claims asserted in a subsequent suit were, or could have been, raised in a prior proceeding, the Court considers “whether the underlying facts are ‘related in time, space, origin, or motivation;’ whether they form a [564]*564convenient trial unit; and whether their treatment as a unit conforms to the parties’ expectations.” Waldman v. Vill. of Kiryas Joel, 207 F.3d 105, 108 (2d Cir. 2000) (quoting Interoceanica Corp. v. Sound Pilots, Inc., 107 F.3d 86, 90 (2d Cir.1997)). Notably, “[r]es judicata does not require the precluded claim to actually have been litigated.” EDP Med. Computer Sys., Inc. v. United States, 480 F.3d 621, 626 (2d Cir.2007) (italics omitted); see also Federated Dep’t Stores, Inc. v. Moitie, 452 U.S. 394, 398, 101 S.Ct. 2424, 69 L.Ed.2d 103 (1981) (affirming that res judicata extends to all claims that “were or could have been raised in that [prior] action” (emphasis added)). In this way, the doctrine applies “not only as to what was pleaded, but also as to what could have been pleaded.” In re Teltronics Servs., Inc., 762 F.2d 185, 193 (2d Cir.1985); see also Magi XXI, Inc. v. Stato Della Cita Del Vaticano, 22 F.Supp.3d 195, 205 (E.D.N.Y.2014) (same). Additionally, “the facts essential to the barred second suit need not be the same as the facts that were necessary to the first suit. It is instead enough that the facts essential to the second were [already] present in the first.” Waldman, 207 F.3d at 110-11 (alteration in original) (emphasis and internal quotation marks omitted). “Even claims based upon different legal theories are barred provided they arise from the same transaction or occurrence [as the claims previously raised].” L-Tec Elecs. Corp. v. Cougar Elec. Org., Inc., 198 F.3d 85, 88 (2d Cir.1999); see also Waldman, 207 F.3d at 110 (“[A] plaintiff cannot avoid the effects of res judicata by ‘splitting’ his claim into various suits, based on different legal theories ....”); Saud v. Bank of N.Y., 929 F.2d 916, 920 (2d Cir.1991) (“[I]t is the factual predicate of the several claims asserted that determines whether res judica-ta will apply, not a litigant’s ability to devise a new legal theory.” (internal quotation marks and some italics omitted)).
In seeking to differentiate the two suits, Plaintiff underscores that the state court “declined to exercise jurisdiction over the matters related to [p]atent[s].” (Pl.’s Mem. of Law Opp’n to Defs.’ Mot. To Dismiss (“Pl.’s Opp’n”) 10-11 (Dkt. No. 86).) Yet, notwithstanding Plaintiffs insistence otherwise, (see, e.g., id. at 11 (“All causes of actions and the relief sought [ ]in ... Plaintiff’s SAC are related to [a patent].”)), this Court’s original jurisdiction over such subject matter, pursuant to 28 U.S.C. § 1338(a), has no bearing on the three contract-related claims at issue here. Plaintiffs claims for unenforceable contract, unjust enrichment, and constructive trust pertain to the Agreement, not to patents also at issue in this case. (See, e.g., SAC ¶ 14 (“Plaintiff alleges that the said [Agreement] was/is invalid and/or unenforceable and/or voidable.”)). Considering that state courts are competent to entertain contract suits, see Gottlieb v. Carnival Corp., 436 F.3d 335, 337 (2d Cir.2006) (noting “state courts are courts of general jurisdiction”), it is clear Plaintiff could have, but did not, assert those claims in his prior suit against PepsiCo.
These claims “arise out of the same factual predicate as the original claims,” L-Tec Elecs., 198 F.3d at 88, namely Plaintiffs work assignment contract. It is well-settled that multiple claims based upon a single contract are considered part of the same transaction, unless the plaintiff could not have asserted a claim in the original action. See Prime Mgmt. Co. v. Steinegger, 904 F.2d 811, 816 (2d Cir.1990) (explaining that, in a suit for breach of contract, “res judicata will preclude the party’s subsequent suit for any claim of breach that had occurred prior to the first suit”). As discussed above, Plaintiff could have raised these contract claims in the state court since the underlying contract pre-dated that suit. For whatever reason he did not, [565]*565and instead he now puts forth allegations that similarly relate to the Agreement. Thus, because the instant Action’s claims for unenforceable contract, unjust enrichment, and constructive trust “share a common nucleus of operative facts with the prior one,” Waldman, 207 F.3d at 108, these three causes of action are barred by res judicata.
2. Validity of the Agreement
Even if res judicata did not preclude Plaintiff from raising these claims here, the causes of actions that arise out of the Agreement would fail nonetheless,
a. Unenforceable Contract Claim
In its prior Opinion dismissing Plaintiffs contract claim, this Court held that “Attachment B is a clear and explicit assignment of all intellectual property from Plaintiff to PepsiCo,” Kamdem-Ouaffo, 2015 WL 1011816, at *11, thereby upholding the validity of the Agreement, see id. at *13 (concluding that “the Agreement governs Plaintiffs rights to the intellectual property at issue”); id. at *14 (“[B]y operation of Attachment B, Plaintiff has no remaining ownership interest in the intellectual property at issue.”). While “Plaintiff challenges the validity and enforceability of Attachment B,” (SAC ¶ 153), the SAC ultimately offers no new factual allegations to alter the Court’s prior conclusion. Plaintiff himself asserts that “[i]t is substantially supported by the same factual background of the [FAC].” (Id. ¶ 153.) Indeed, his bare allegations of “lack of [m]utual [a]ssent, failure to disclose material facts to ... Plaintiff, [and] ambiguity,” (id. ¶ 159 (internal quotation marks omitted)), are no more than “naked assertions devoid of further factual enhancement,” Iqbal, 556 U.S. at 678,129 S.Ct. 1937 (alteration and internal quotation marks omitted). As such, his unsubstantiated challenges to the validity of the Agreement fail to establish any right to relief.
On one hand, Plaintiff alleges lack of mutual assent on the basis that “he was never given the opportunity to review the entire [Agreement]” and thus did not fully understand its content. (SAC ¶ 167; see also Pl.’s Opp’n 10 (“Plaintiff was never provided a copy of the executed agreements until during discovery of the [state court] lawsuit.”).) However, under New York law, “[a] party’s failure to read or understand a contract that it signs does not relieve it of its obligation to be bound by the contract.” In re Lehman Brothers Inc., 478 B.R. 570, 587 n. 19 (S.D.N.Y.2012), aff'd sub nom. In re Lehman Bros. Holdings Inc., 761 F.3d 303 (2d Cir.2014); see also Brandywine Pavers, LLC v. Bombard, 108 A.D.3d 1209, 970 N.Y.S.2d 653, 655 (2013) (“A party is under an obligation to read a document before he or she signs it, and a party cannot generally avoid the effect of a document on the ground that he or she did not read it or know its contents.” (alterations and internal quotation marks omitted)); Superior Officers Council Health & Welfare Fund v. Empire Health-Choice Assurance, Inc., 85 A.D.3d 680, 927 N.Y.S.2d 324, 326 (2011) (“[P]arties are presumed to know the contents of the agreements they have signed.”), aff'd, 17 N.Y.3d 930, 935 N.Y.S.2d 574, 959 N.E.2d 511 (2011). Accordingly, Plaintiffs contention that he did not read or understand the entirety of the “voluminous document,” (SAC 11160), by itself, does not void the Agreement. Because Plaintiff provides no other reason to invalidate the Agreement, it should be enforced according to its terms. See Marciano v. DCH Auto Grp., 14 F.Supp.3d 322, 330 (S.D.N.Y.2014) (enforcing an agreement against a party who claimed that “she did not read the entire ... [a]greement” before signing it); Martin v. Creative Mgmt. Grp., Inc., No. 10-CV-2214, 2010 WL 2629580, at *2 (S.D.N.Y. June 29, 2010) (“[A] person who signs a written contract is bound by its terms regardless of his or her failure to [566]*566read and understand its terms.” (internal quotation marks omitted)).14
In addition, Plaintiff “seek[s] to have the contract voided by the Court and/or found to be unenforceable” due to an alleged breach of “an implied covenant of good faith and fair dealing between PepsiCo and ... Plaintiff.” (SAC ¶¶205, 208.) Yet, under New York law, only parties to a contract can be held liable for breach of the implied covenant of good faith and fair dealing. See Ray Legal Consulting Grp. v. DiJoseph, 37 F.Supp.3d 704, 727 (S.D.N.Y.2014) (holding that “an action for breach of the implied covenant of good faith and fair dealing of [an] agreement cannot lie against” those who were not party to it); Am.-European Art Assocs., Inc. v. Trend Galleries, Inc., 227 A.D.2d 170, 641 N.Y.S.2d 835, 836 (1996) (dismissing a “cause of action for breach of an implied duty of good faith and fair dealing by [the] defendants” due to the absence “of a valid and binding contract from which such a duty would arise”). The plain terms of the Agreement make clear that PepsiCo and its employees were not a party to the work assignment contract. (See, e.g., Agreement, at Attachment B (referring to “my employer, the Staffing Supplier named below”); id. at Attachment C ¶ 1(“I understand that I am an employee of the Staffing Supplier [Subex,] and I am not an employee of PepsiCo.”).) This Court, in fact, has already determined that “under the plain terms of the Agreement, PepsiCo cannot be liable for any breach of contract under the Agreement, to which it was not a party.” Kamdem-Ouaffo, 2015 WL 1011816, at *7 (emphasis added).15 Furthermore, while Plaintiff accurately notes that a valid contract requires “an intent to be bound,” (SAC ¶ 157 (citing Kowalchuk v. Stroup, 61 A.D.3d 118, 873 N.Y.S.2d 43, 46 (2009))), there is no specific allegation that PepsiCo Defendants manifested such intent that could impose contractual obligations on them.16 Because [567]*567they were not parties to the Agreement, Plaintiff cannot state a contractual claim for breach of the implied covenant of good faith and fair dealing against PepsiCo, Dr. Given, and Dr. Zhang.
Plaintiff also claims the Agreement is unenforceable because “there was no definiteness” as to his compensation. (Id. ¶ 196.) However, this Court already determined that the Agreement did indeed specify his compensation. See Kamdem-Ouaffo, 2015 WL 1011816, at *10 (recognizing the $82,142 that Plaintiff received “as compensation” to be “the consideration that he was promised on the face of the Agreement”). Moreover, as this Court also previously held, “[u]nder the Agreement, Plaintiff was clearly an employee of Subex, and not of PepsiCo.” Id. at *7. Precisely because the Agreement unambiguously indicates Plaintiff’s employer as Subex, not PepsiCo, (cf. SAC ¶208 (acknowledging that “PepsiCo did not directly sign ... Attachment B”)), no parol evidence is “admissible to suggest that PepsiCo promised that Plaintiffs name would remain on his inventions, or that PepsiCo owed him compensation as his employer,” Kamdemr-Ouaffo, 2015 WL 1011816, at *9; see also Schron v. Troutman Sanders LLP, 20 N.Y.3d 430, 963 N.Y.S.2d 613, 986 N.E.2d 430, 436 (2013) (affirming that “evidence outside the four corners of the document” is admissible to modify or contradict a written agreement “only if a court finds an ambiguity in the contract”). For these reasons, the Court again rejects Plaintiffs attempt to challenge the definiteness of the Agreement.
Lastly, Plaintiff alleges that PepsiCo Defendants “voided the contract” through “either fraud in the execution or fraud in the inducement, with respect to [ ]Attachment B.” (SAC ¶¶ 212, 221.) Yet, such allegations once again fail to meet the heightened pleading standard required for fraud claims. See Kamdem-Ouaffo, 2015 WL 1011816, at *12 (“It long has been clear that ‘[a]llegations of fraud are subject to a heightened pleading standard.’ ” (alteration in original) (quoting Nakahata v. N.Y.-Presbyterian Healthcare Sys., Inc., 723 F.3d 192, 197 (2d Cir.2013))); see also Fed. R. Civ. P. 9(b) (“In alleging fraud or mistake, a party must state with particularity the circumstances constituting fraud or mistake.”). To survive a motion to dismiss a fraud-based claim, “a party must state with particularity the circumstances constituting fraud, ... which ... requires the plaintiff to (1) specify the statements that the plaintiff contends were fraudulent, (2) identify the speaker, (3) state where and when the statements were made, and (4) explain why the statements were fraudulent.” Nakahata, 723 F.3d at 197 (internal quotation marks omitted). Though he claims “the way Defendants worked the fraud was that they first expunged the Plaintiffs name from his inventions,” (SAC ¶ 219), Plaintiff, for a second time, fails to satisfy the fourth prong of the pleading standard in not specifying any federal or state law that Defendants have violated, see Kamdemr-Ouaffo, 2015 WL 1011816, at *12 (“Plaintiff does not explain how PepsiCo’s actions were fraudulent given that an assignee of intellectual property is permitted to make a patent application” (citing 35 U.S.C. § 118 (“A person to whom the inventor has assigned ... the invention may make an application for patent.”))). Even had Plaintiff intended to allege common law fraud under New York law, he nonetheless fails to allege facts that establish the elements of such a claim, as the SAC, like the FAC, does not allege reliance on a misrepresentation of material [568]*568fact or resulting economic detriment. See id. (noting that “the elements of a common law fraud claim are: (1) a misrepresentation of material fact, (2) made with fraudulent intent, (3) upon which the plaintiff reasonably relies to his (4) economic detriment” (internal quotation marks omitted)).
Given these considerations, Plaintiff cannot sustain a claim for an unenforceable contract even if it were not barred by res judicata.
b. Unjust Enrichment Claim
Having reaffirmed the enforceability of the Agreement in the absence of any new factual allegations, the Court again rejects Plaintiffs unjust enrichment claim. See id. at *13 (dismissing Plaintiffs unjust enrichment claim). The SAC alleges that “Defendants[J or at least some of ... Defendants, have been and continue to be unjustly enriched by asserting ... they own and/or are inventors of Plaintiff[’]s [intellectual [p]roperty.” (SAC ¶ 261.) Yet, as previously noted by this Court, the remedy of “[ujnjust enrichment is not available where there is a valid contract between the parties covering the same subject matter.” Arbitron, Inc. v. Kiefl, No. 09-CV-4013, 2010 WL 3239414, at *7 (S.D.N.Y. Aug. 13, 2010); see also Am. Med. Ass’n v. United Healthcare Corp., No. 00-CV-2800, 2007 WL 683974, at *10 (S.D.N.Y. Mar. 5, 2007) (“[D]ecisions both in New York state courts and in [the Southern District of New York] have consistently held that claims for unjust enrichment may be precluded by the existence of a contract governing the subject matter of the dispute .... ”). As discussed above and in its prior decision by this Court, the Agreement “contractually transferred [Plaintiffs] intellectual property to PepsiCo.” Kamdem-Ouaffo, 2015 WL 1011816, at *11. This valid contract thus governs Plaintiffs rights to the subject matter at issue and precludes this second cause of action, regardless of the applicability of res judicata.
c. Constructive Trust Claim
Plaintiff repeats his earlier claim that he is entitled to a constructive trust related to certain patents outlined in the SAC.17 Yet, as with the remedy of unjust enrichment, it is well-settled that a constructive trust cannot be imposed where a valid agreement covers the subject matter of the dispute. See In re First Cent. Fin. Corp., 377 F.3d 209, 215 (2d Cir.2004) (“[W]here a valid agreement controls the rights and obligations of the parties, an adequate remedy at law typically exists” such that “a constructive trust should not be imposed.” (internal quotation marks omitted)); N. Shipping Funds I, LLC v. Icon Capital Corp., 921 F.Supp.2d 94, 107 (S.D.N.Y.2013) (dismissing a claim for constructive trust because “[the plaintiff] has a contractual claim against [the defendant]”); Spanierman Gallery, PSP v. Love, No. 03-CV-3188, 2003 WL 22480055, at *4 (S.D.N.Y. Oct. 31, 2003) (dismissing a constructive trust claim because, under New York law, the “existence of a valid and enforceable written contract governing a particular subject matter ordinarily precludes recovery in quasi contract for events arising out of the same subject matter” (internal quotation marks omitted)).18 The equitable remedy of a constructive trust is unavailable in the instant Action precisely because of the Agree[569]*569ment. (See Agreement, at Attachment B ¶A (assigning to PepsiCo any “right, title[,] and interest in and to all ... ‘Intellectual Property’ ... conceived ... during the period of such work or performance of assignments” (emphasis added)).) Therefore, res judicata aside, Plaintiff’s constructive trust claim fails. See Abraham v. Am. Home Mortg. Servicing, Inc., 947 F.Supp.2d 222, 235 (E.D.N.Y.2013) (rejecting a constructive trust claim because “[i]t is well established that the existence of a contract precludes a claim for a constructive trust”).
C. Correction of Inventorship
Repeating yet another claim from the dismissed FAC, Plaintiff seeks correction of ownership for at least two intellectual property items outlined in the SAC.19 He alleges that, “[i]n view of ... 35 U.S.C § 261, ... Plaintiff still has interest in the patents and patent applications of ... Plaintiff[’]s [intellectual property] that he created at PepsiCo.” (SAC ¶ 212.) Even taking as true that “it is undisputed ... Plaintiff is the true inventor of the two patents” at issue, (id. ¶ 108), the Court, for the same reasons as before, dismisses this cause of action, see Kamdem-Ouaffo, 2015 WL 1011816, at *14 (dismissing correction of inventorship claim on the basis that § 256 “does not provide a private right of action to challenge inventorship of a pending patent application” and because Plaintiff assigned his intellectual property rights to PepsiCo, he lacks standing to make a claim” as to the single issued patent (internal quotation marks omitted)).
To the extent that Plaintiff seeks to once again bring a correction of inventorship claim for any patent application referenced in the SAC, (see, e.g., SAC ¶¶ 48, 60), such an attempt must be denied. As this Court has already emphasized, there is no “private right of action to challenge inventorship of a pending patent application.” HIF Bio, Inc. v. Yung Shin Pharm. Indus. Co., 600 F.3d 1347, 1354 (Fed.Cir.2010); see also Kamdem-Ouaffo, 2015 WL 1011816, at *14 (“Plaintiff cannot bring a cause of action for a correction of inventorship for the four pending patent applications.”). This is equally true for abandoned patents, as “a district court lacks jurisdiction to review the inventor-ship of an unissued patent.” Camsoft Data Sys., Inc. v. S. Elecs. Supply, Inc., 756 F.3d 327, 335 (5th Cir.2014) (alteration and internal quotation marks omitted), cert. denied, — U.S. -, 135 S.Ct. 1162, 190 L.Ed.2d 914 (2015); see also E.I. Du Pont de Nemours & Co. v. Okuley, 344 F.3d 578, 584 (6th Cir.2003) (same).20 Accordingly, [570]*570Plaintiff cannot bring a correction of inven-torship claim for any of the referenced patent applications, whether pending or otherwise.
While 35 U.S.C. § 256 “provides a private right of action to challenge inventorship” for issued patents, Kamdem-Ouaffo, 2015 WL 1011816, at *14 (internal quotation marks omitted), “a plaintiff seeking correction of inventorship under § 256 can pursue that claim in federal court only if the requirements for constitutional standing — namely injury, causation, and redressability — are satisfied,” Larson v. Correct Craft, Inc., 569 F.3d 1319, 1326 (Fed.Cir.2009). As before, the Court finds that Plaintiff lacks standing to make such a claim because, pursuant to the Agreement, he assigned his patent rights to PepsiCo. {See generally Attachment B.) Plaintiff thus has no remaining ownership interest in the disputed intellectual property, including the “patent from ... Plaintiffs intellectual property [that] was granted on July 2, 2013 as US Patent No. 8,474,637 B2.” (SAC ¶ 41; cf. id. ¶ 18 (“Defendants have already been granted a utility patent by the [USPTO] as Patent No. US 8,474,637 B2.”).)
Furthermore, Plaintiffs conclusory allegations of “damages in terms of the loss of the ownership, inventorship, recognition, and the honor for his valuable, marketable, confidential, patentable and now patented [i]ntellectual [property” do not suffice, (SAC ¶ 304), as the Agreement unmistakably leaves Plaintiff with none of the requisite interests for standing, see Larson, 569 F.3d at 1327 (concluding that the plaintiff “has no financial interest in the patents sufficient for him to have standing to pursue a § 256 claim”); Jim Arnold Corp. v. Hydrotech Sys., Inc., 109 F.3d 1567, 1572 (Fed.Cir.1997) (finding the plaintiff lacked standing to pursue a patent infringement claim where he had assigned away all his patent rights and thus did not have an ownership interest in the patents); Swanson v. ALZA Corp., No. 12-CV-4579, 2013 WL 968275, at *4 (N.D.Cal. Mar. 12, 2013) (“Where an inventor assigns all of his interest in an invention to others, he retains no financial interest in the patents and therefore no interest sufficient for him to have standing to pursue a § 256 claim.” (internal quotation marks omitted)). In light of this principle, Plaintiffs correction of inventorship claim is dismissed.
[571]*571D. Defamation
As the one fresh cause of action presented in the SAC, Plaintiff alleges that “[Pep-siCo] Defendants knowingly and willfully made written false statements against ... Plaintiff to attack ... Plaintiffs performance on his job and profession, and to attack ... Plaintiffs moral character.” (SAC ¶ 308.)21 However, his defamation action comes too late and, furthermore, fails to state a viable claim.
1. Statute of Limitations
According to Plaintiff, “[t]he said written defamatory statements were made [by PepsiCo Defendants] to the United States government in a document dated 12/18/2009.” (Id.; see also id. ¶39 (“Pepsi-Co and its protégés publically and deceitfully made representation[s] ... in a letter dated 12/18/2009.”).) New York Civil Practice Law and Rules (“CPLR”) § 215(3) requires that an action for defamation “be commenced within one year,” that is, within one year of the original publication of the statements. See Melious v. Besignano, 125 A.D.3d 727, 4 N.Y.S.3d 228, 229 (2015) (“A cause of action alleging defamation is governed by a one-year statute of limitations ... [that] accrues at the time the alleged statements are originally uttered.”); see also Tucker v. Wyckoff Heights Med. Ctr., 52 F.Supp.3d 583, 596-97 (S.D.N.Y.2014) (“Under CPLR § 215(3), a claim for libel must be asserted within one year of the date on which the libelous material first was published, that is, displayed to a third party.” (internal quotation marks omitted)), appeal dismissed (Feb. 26, 2015). Notwithstanding that Plaintiff allegedly “discovered in 2012 that on 12/18/2009 [PepsiCo] Defendants had written to the United States government,” (SAC ¶ 67; see also Pi’s Opp’n 26 (stating that the document “was discovered as part of a judicial proceeding [before] the State Supreme Court”)), any action for defamation accrued when the alleged statements were first published such that he needed to commence suit within one year of December 18, 2009.22 A later discovery of defamatory material does not toll the one-year statute of limitations. See Teneriello v. Travelers Cos., 226 A.D.2d 1137, 641 N.Y.S.2d 482, 483 (1996) (“Contrary to [the] plaintiffs contention, the action accrued when the statements were originally published ..., not upon [the] plaintiffs discovery of the statements two years later.”); Karam v. First Am. Bank of N.Y., 190 A.D.2d 1017, 593 N.Y.S.2d 640, 642 (1993) (“In an action for slander, the [s]tatute of [Limitations runs from the time [572]*572of the utterance, not the discovery of the slanderous matter.”).
Attempting to keep alive his defamation claim, Plaintiff asserts that, pursuant to “CPLR [§ ] 203(g), Plaintiff has two years from the date of imputation to commence action.” (Pi’s Opp’n 26.) This reliance on CPLR § 203(g) is misplaced, however, as § 215 does not provide that the statute of limitations for defamation accrues from discovery.23 Again, the case law is clear: a defamation claim has a one-year statute of limitation that “accrues on the date of the first publication.” Gelbard v. Bodary, 270 A.D.2d 866, 706 N.Y.S.2d 801, 802 (2000); see also E.B. v. Liberation Publ’ns, Inc., 7 A.D.3d 566, 777 N.Y.S.2d 133, 134 (2004) (“The accrual of a cause of action for libel occurs upon the ’publication’ of the offending material, which has been repeatedly defined as the date on which the offending material was placed on sale or became generally available to the public.”); Kilbourne v. State, 111 Misc.2d 161, 443 N.Y.S.2d 538, 540 (N.Y.Ct.CL 1980) (“It is not disputed that a cause of action in defamation accrues on the dates of publication of the alleged libelous statement or the date the allegedly slanderous matter is uttered.”). Moreover, Plaintiff cannot seek to evade the statute of limitations through allegations that “[u]p to this date, ... [Defendants continued to defame ... Plaintiff in written documents.” (SAC ¶ 254.) Under New York law, “a cause of action for defamation accrues immediately upon the occurrence of the tortious act and thus, is not appropriate for the continuing violation exception.” Lettis v. U.S. Postal Serv., 39 F.Supp.2d 181, 205 (E.D.N.Y.1998); see also Nussenzweig v. diCorcia, 9 N.Y.3d 184, 848 N.Y.S.2d 7, 878 N.E.2d 589, 590 (2007) (“[T]he single publication rule ... states that a cause of action for defamation accrues on the date the offending material is first published”).24 It is thus clear that Plaintiffs defamation action accrued on December 18, 2009.
Plaintiff filed the SAC on March 25, 2015, meaning that any claims for defamation prior to March 25, 2014 are time barred. Because Plaintiffs allegations here all rest on “the same 12/18/2009 letter to the United States government,” (SAC 1168), the Court dismisses this final cause of action.
[573]*5732. Failure to State a Claim
In addition to being time barred, Plaintiffs defamation action fails to state a viable claim. “To establish a claim for defamation under New York law, a plaintiff must prove that: (1) the defendant published a defamatory statement of fact to a third party, (2) that the statement of fact was false, (3) the false statement of fact was made with the applicable level of fault, and (4) either the false statement was defamatory per se or caused the plaintiff special harm.” Medcalf v. Walsh, 938 F.Supp.2d 478, 485 (S.D.N.Y.2013).
In the instant Action, Plaintiff cannot satisfy these elements because the document to which Plaintiff refers as containing “the job performance and sexual defamations” does not actually contain such statements. (SAC ¶ 306.)25 The SAC alleges that PepsiCo defamed him “by stating ... that ... Plaintiff is a Food Scientist with ‘unsatisfactory performance,’ ” (id. ¶ 181 (italics omitted)), and by “represent[ing] in the same 12/18/2009 letter to the United States government that ... Plaintiff was going to work ... only for the purpose of predatory sexual intercourse,” (id. ¶ 68 (italics omitted)). In fact, the referenced letter merely articulates PepsiCo’s “legitimate, non-retaliatory reasons for not offering a permanent, full-time position to [Plaintiff].” (PepsiCo’s Letter 13.)26 “A statement of opinion that is accompanied by a recitation, of the facts on which it is based or one that does not imply the existence of undisclosed underlying facts is protected as a statement of opinion and thus not a false statement of fact.” Medcalf, 938 F.Supp.2d at 486 (alteration and internal quotation marks omitted) (quoting Gross v. N.Y. Times Co., 82 N.Y.2d 146, 603 N.Y.S.2d 813, 623 N.E.2d 1163, 1168 (1993)). Describing in detail Plaintiffs work history, (see PepsiCo’s Letter 2-7), PepsiCo’s Letter never “implies a basis in facts which are not disclosed to the reader or listener,” Gross, 603 N.Y.S.2d 813, 623 N.E.2d at 1168; see also Levin v. McPhee, 119 F.3d 189, 197 (2d Cir.1997) (“When the defendant’s statements, read in context, are readily understood as conjecture, hypothesis, or speculation, this signals the reader that what is said is opinion, and not fact.”). Examining the statements in context, it is clear that “the unfavorable assessment of his work performance in the letter amounted to a nonactionable expression of opinion.” Ott v. Automatic Connector, Inc., 193 A.D.2d 657, 598 N.Y.S.2d 10, 11 (1993); see also id. (“An employer has the right to assess an employee’s performance on the job without judicial interference.”). For that reason, Plaintiffs defamation claim would fail regardless of its untimeliness, and the Court thus dismisses this final cause of action.27
[574]*574III. Conclusion
For the foregoing reasons, Defendants’ Motions To Dismiss are granted, and Plaintiffs Second Amended Complaint is dismissed with prejudice.28 The Clerk of the Court is respectfully requested to terminate the pending Motions, (see Dkt. Nos. 72, 75), and close the case.
