ORDER ON PARTIAL MOTION TO DISMISS
WILLIAM H. ORRICK, United States District Judge
INTRODUCTION
This is a patent infringement action in which plaintiff Word to Info, Inc. (“WTI”) accuses defendant Google, Inc. of infringing seven related patents claiming techniques for natural language processing,1 Google filed this partial motion to dismiss [988]*988seeking dismissal of: (Í) WTI’s willful infringement claims, on the ground that they are based exclusively on Google’s alleged post-filing knowledge of the patents-in-suit; and (2) WTI’s claims of infringement of the ’091, ’840, ’509, ’603,. and ’436 patents, on the ground that due to errors during the application process in describing the chain of priority for these patents, each is now invalid as a matter of law. I agree with Google that WTI’s claims of willful infringement should be dismissed because they are based exclusively on Google’s knowledge since the filing of the complaint, and I agree with WTI that a certificate of correction under 35 U.S.C. § 255 may be used to correct a mistaken or omitted “specific reference” for. the purposes of 35 U.S.C. § 120. For those reasons, Google’s motion is GRANTED IN PART and DENIED IN PART.
BACKGROUND
WTI filed this action on December 15, 2014 in the United States District Court for the Northern District of Texas. Dkt. No. 1. While the case was still pending in that district, Google filed this partial motion to dismiss. Dkt. No. 13. The motion was fully briefed when the case was transferred to this district on July 29, 2015. Dkt. No. 56. On September 8, 2015, Google renoticed the motion for hearing, and I heard argument from the parties on September 23, 2015. Dkt. No. 82.
WTI claims that Google willfully infringes the ’468, ’091, and ’840 patents. Compl. ¶¶ 23-24, 33-34, 39-40. Using identical language with respect to each of these three patents, WTI alleges that
Google was made aware' of the [patent] and its infringement thereof at least' as early as the filing of this complaint.
On information and belief, therefore, Google’s continued infringement of the [patent] is willful and deliberate, entitling plaintiff to enhanced damages under 35 U.S.C. § 284 and attorneys’ fees and nontaxable costs under 35 U.S.C. § 285. -
Id. There are no other allegations in the complaint regarding willful infringement.
LEGAL STANDARD
Federal Rule of Civil Procedure 8(a)(2) requires a complaint to contain “a short and plain statement, of the claim showing that the pleader is entitled to relief,” Fed. R. Civ. P. 8(a)(2), in order to “give the defendant fair notice of what the claim is and the grounds upon which it rests,” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 555, 127 S.Ct. 1955, 167 L.Ed.2d 929 (2007) (internal quotation marks and alterations omitted).
A motion to dismiss for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6) tests the legal sufficiency of a complaint. Navarro v. Block, 250 F.3d 729, 732 (9th Cir.2001). “Dismissal under Rule 12(b)(6) is appropriate only where the complaint lacks a cognizable legal theory or sufficient facts to support a cognizable legal theory.” Mendiondo v. Centinela Hosp. Med. Ctr., 521 F.3d 1097, 1104 (9th Cir.2008). While a complaint “need not contain detailed factual allegations” to survive a [989]*989Rule 12(b)(6) motion, “it must plead enough facts to state a claim to relief that is plausible on its face.” Cousins v. Lockyer, 568 F.3d 1063, 1067-68 (9th Cir.2009) (internal quotation marks and citations omitted). A claim is facially plausible when it “allows the court to draw the reasonable inference that the defendant is liable for the misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 678, 129 S.Ct. 1937, 173 L.Ed.2d 868 (2009) (internal quotation marks omitted).
In considering whether a claim satisfies this standard, the court must “accept factual allegations in the complaint as true and construe the pleadings in the light most favorable to the nonmoving party.” Manzarek v. St. Paul Fire & Marine Ins. Co., 519 F.3d 1025, 1031) (9th Cir.2008). However, “conclusory allegations of law and unwarranted inferences are insufficient to avoid a Rule 12(b)(6) dismissal.” Cousins, 568 F.3d at 1067 (internal quotation marks bmitted). “[I]t is within [the court’s] wheelhouse to reject, as implausible, allegations that are too speculative to warrant further factual development.” Dahlia v. Rodriguez, 735 F.3d 1060, 1076 (9th Cir.2013).
DISCUSSION
I. WILLFUL INFRINGEMENT
Google contends that WTI’s claims of willful infringement of the ’468, ’091, and ’840 patents should be dismissed because they are based exclusively on Google’s alleged post-filing knowledge of the patents. See Mot. at 4-5 (Dkt. No. 15); Reply at 1-2 (Dkt. No. 39). I agree, and Google’s motion to dismiss these claims is GRANTED.
Although patent infringement is a strict liability offense, a patentee, may obtain enhanced damages where it establishes that the defendant’s infringement was “willful.” In re Seagate Tech., LLC, 497 F.3d 1360, 1368 (Fed.Cir.2007). A pat-entee claiming willful infringement must show by clear and convincing evidence that the accused infringer “acted despite an objectively high likelihood that' its actions constituted infringement of a valid patent.” Id. at 1371. “If this threshold objective standard is satisfied, the patentee must also demonstrate that this objectively defined risk.. .was either'known or So obvious that it should have been known to the accused infringer.” Id. Because “a party cannot be found to have willfully infringed a patent of which the party had- no knowledge,” Gustafson Inc. v. Intersystems Indus. Products, Inc., 897 F.2d 508, 511 (Fed.Cir.1990) (internal quotation marks omitted), “[knowledge of the paten[t] is essential to a claim of. willful infringement,” Radware, Ltd. v. A10 Networks, Inc., No. 13-CV-02021-RMW, 2013 WL 5373305, at *6 (N.D.Cal. Sept. 24, 2013).
“[A] patentee must have a good faith basis for alleging willful infringement.” Seagate, 497 F.3d at 1374 (citing Fed. R. Civ. P. 11). Accordingly, a willful infringement claim “in the original complaint must necessarily be grounded exclusively in the accused infringer’s pre-filing conduct.” Id. In line with this rule, courts dismiss willfulness claims in original pleadings where the defendant’s only alleged basis for knowing of the patents-in-suit is the filing of the action itself. See, e.g., CAP Co. v. McAfee, Inc. No. 14-cv-05068-JD, 2015 WL 3945875, at *2. (N.D.Cal. June 26, 2015) (dismissing -willful infringement claims where the patentee “does not allege that defendants had any pre-suit knowledge of the patents”); Touchscreen Gestures LLC v. Research in Motion Ltd., No. 12-CV-00263, 2013 WL 8505349, at *2 (E.D.Tex. Mar. 27, 2013) (“[T]he complaint presents no facts supporting that [plaintiff] had a good faith basis for alleging willful [990]*990infringement. The absence of any allegation of pre-filing knowledge of the patents is fatal to [plaintiffs] willful infringement claims.”); Select Retrieval, LLC v. L. L. Bean, Inc., No. 12-cv-00003, 2012 WL 5381503, at *5 (D.Me. Oct. 31, 2012) (“The complaint doe's not provide any facts as to the defendant’s conduct before October 17, 2011, when the Plaintiff originally filed this lawsuit. Without such facts, the plaintiff has not plausibly;pleaded its claim.of willful infringement.”).
Like the willful infringement claims in these cases, WTI’s willful infringement claims fail because they are based exclusively on Google’s alleged post-filing knowledge of the relevant patents. WTI claims that Google knew of the ’468, ’091, and ’840 patents “at least as early as the filing of this complaint.” Compl. ¶¶ 23-24, 33-34, 39-40. The complaint contains no other allegations regarding , Google’s knowledge of or conduct with respect to the relevant patents. This is far from enough to plausibly establish that Google has willfully infringed. “The absence of any allegation of pre-filing knowledge of the patents is fatal to [WTI’s] willful infringement claims.” Touchscreen, 2013 WL 8505349, at *2.
The cases cited by WTI do not call for a different result. The bulk of them concern situations where the defendant learned of the patents-in-suit from some source other than the complaint under review. See, e.g., MyMedicalRecords, Inc. v. Jardogs, LLC, 1 F.Supp.3d 1020, 1026 (C.D.Cal.2014) (denying motion to dismiss willfulness claim in second amended complaint, where defendant allegedly learned of patents from previous complaints). The rest address a different issue — i.e., whether under Sea-gate a patentee must seek a preliminary injunction to prevail on a willful infringement claim based on post-filing conduct. See, e.g., DataQuill Ltd. v. High Tech Computer Corp., 887 F.Supp.2d 999, 1014-17 (S.D.Cal.2011) (rejecting argument that “Seagate creates a per se bar to any claim for willful infringement based on post-filing conduct where the patentee did not seek a preliminary injunction”). Because these cases are either easily distinguishable from this one, or are inapplicable at this juncture, they do not help WTI.2
All claims of willful infringement in the complaint are DISMISSED. In case WTI knows of facts that have not yet been pleaded that provide a good faith basis for accusing Google of .willful infringement based on pre-filing conduct, I will grant LEAVE TO AMEND. If WTI develops a good faith basis for accusing Google of willful infringement based on post-filing conduct, it may seek leave to add such claims under Federal Rule of Civil Procedure 15.
II. 35 U.S.C. § 120
A. Google’s Argument
Google moves to dismiss WTI’s claims of infringement of the ’091, ’840, ’509, ’603, and ’436 patents, on the ground that due to errors during the application process in describing the chain of priority for these patents, each is now invalid as a matter of law.
[991]*991Some additional background -is necessary to appreciate Google’s argument. The seven patents-in-suit are related to one another through a chain of patent applications. See Mot. at 6. The first application in the chain, for the ’468 patent, was filed on September 30, 1994.' Id, The applications for each of the subsequent six patents-in-suit states that it is a continuation of one or more of the prior applications in the chain. Id.
A continuation application “is a second application for the same invention claimed in a prior nonprovisional application.” MPEP § 201.07 (9th ed. 2014). The continuation must be filed before the prior non-provisional application is abandoned or patented. Id Google states that “continuation applications are part of a well-established practice of allowing inventors to file new patent applications based on the disclosures of previous applications, without having the previous applications be treated as invalidating prior art.” Mot. at 6.
35 U.S.C. § 120 sets forth the basic requirements for continuation applications:
An application for patent for an invention disclosed.. .in an application previously filed in the United States.. .which names an inventor or joint inventor in the previously filed, application shall have the same effect, as to such invention, as though filed on the date of the prior application, if filed before the patenting or abandonment of or termination of proceedings on the first application or on an application similarly entitled to the benefit of the filing date of the first application and if it contains or is amended to contain a specific reference to the earlier filed application.
No application shall be entitled to the benefit of an earlier filed application under this section unless an amendment containing the specific reference to the earlier filed application is submitted at such time during the pendency of the application as required by the Director. The Director may consider the failure to submit such an amendment within that time period as a waiver of any benefit under this section. The Director may establish procedures... to aceept an unintentionally delayed submission of an amendment under this section.
35 U.S.C. § 120 (paragraphing added).3
Google’s argument focuses on the section 120 requirement that the continuation “contain[n] or [be] amended to contain a specific reference to the earlier filed application.” 35 U.S.C. § 120. In Medtronic CoreValve, LLC v. Edwards Lifesciences Corp., 741 F.3d 1359 (Fed.Cir.2014), the Federal Circuit construed this requirement to mean that where a continuation claims an earlier priority date through a chain of earlier filed applications, the continuation must “specifically reference each earlier filed application.. .in the chain of priority.” Id. at 1367; see also Encyclopaedia Britannica, 609 F.3d at 1352 (holding that the section 120 specific reference requirement mandates that “each application in the chain of priority.. .refer to the prior applications”).
The applications for the patents-in-suit were filed, and the patents were issued, in the following order: (1) ’468 patent (filed Sep. 30, 1994; issued Feb. 3,1998); (2) ’087 [992]*992patent (filed Sep. 24, 1997; issued Oct. 24, 2000); (3) ’091 patent (filed Sep. 27, 2000; issued Aug. 19, 2003); (4) ’840 patent (filed Aug. 8, 2003; issued Mar. 25, 2008); (5) .’509 patent (filed Mar. 20, 2008; issued Jan. 18, 2011); (6) ’603 patent (filed Jan. 14, 2011; issued Dec. 4, 2012); and (7) ’436 patent (filed Nov. 30, 2012; issued Apr. 1, 2014). See Compl. ¶¶ 9-15, Exs. A-G.
The ’087 patent application, the ’091 patent application, and the ’840 patent application each made specific reference only to the ’468 patent application — the ’091 patent application did not reference the ’087 patent application, and the ’840 patent did not reference either the ’091 patent application or the ’087 patent application.
On this ground, Google" contends that the ’091 and ’840 patents are not entitled to the priority date of the ’468 patent and, hence, are anticipated and invalidated" by the ’468 patent, which was issued on February 3, 1998, before the applications for the ’091 and ’840 patents were filed. See Mot. at 16-18.
Google then takes its argument a step further. It acknowledges that the applications for the ’509, ’603, and ’436 patents (in contrast with the applications for the ’091 and ’840 patents) correctly listed all earlier filed applications in the chain of priority. See Mot. at 18-20. .Nevertheless, Google contends that these patents are also anticipated and invalidated by the ’468 patent, because the defects in the applications of the ’091 and ’840 patents destroy the whole chain of priority. See id.
The ’091 and ’840 patents were issued in 2003 and 2008, respectively. Compl. ¶¶ 11-12. Google does not dispute that the inventor of the ’091 and ’840 patents obtained certificates of correction in 2012 and 2013 adding a complete and correct chain of priority to each patent. See Mot. at 11-12. Under 35 U.S.C. § 255,
[w]henever a mistake of a clerical or typographical nature, or of minor character, which was not the fault of the Patent and Trademark Office, appears in a patent and a showing has been made that such mistake occurred in good faith, the Director may, upon payment of the required fee, issue a certificate of correction, if the correction does not involve such changes in the patent as would constitute new matter or would require re-examination. Such patent, together with the certificate, shall have the same effect and operation in law on the trial of actions for causes thereafter arising as if the same had been originally issued in such corrected form.
35 U.S.C. § 255. According to Google, however,' a certificate of correction under section 255 cannot be used to correct a defective chain of priority in a continuation application. Google states that this is because of the section 120 reqüirement that “[n]o application shall be entitled to the benefit of an earlier "filed application.. .unless an amendment containing the specific reference to the earlier filed application is submitted at such time during the pen-dency of the application as required by the Director.” 35 U.S.C. § 120 (emphasis added).-Google contends that “[t]his sentence unambiguously requires that any amendment to an application to seek the benefit of an earlier filing date must be made, while the application is still pending,” not through a section 255 certificate of correction after the patent has been issued. See Mot. at 12.
B. WTI’s Response
WTI disputes only one aspect of Google’s argument — that the inventor’s certificates of correction were ineffective to correct the priority chains stated in the ’091 and ’840 patents. According to WTI, a section 255 certificate of correction may be used to correct a mistaken or [993]*993omitted “specific reference” for the purposes of section 120.
Among other points, WTI emphasizes that section 120 provides only that “[t]he Director may consider the failure to submit such an amendment within that time period as a waiver of any benefit under this section.” Id. (emphasis added), WTI also notes that pursuant to the final sentence of section 120, “[t]he Director may establish procedures.. .to accept an unintentionally delayed submission of an amendment under this section.” Id.
C. Analysis
While neither party cites any binding authority that squarely addresses this issue, I am persuaded that WTI has the better argument. Google’s position is based on a hypertechnical reading of sections 120 and 255 that ignores longstanding PTO practice as well as the case law that exists concerning the interaction between the two statutes.
First, as WTI points out, section 120 does not require the PTO to consider the failure to identify the correct chain of priority in a continuation as a waiver of the earlier priority date.' It provides only that “[t]he Director may consider the failure to submit such an amendment within that time period as a waiver of any benefit under this section.” 35 U.S.C. § 120 (emphasis added). It also authorizes “[t]he Director [to] establish procedures.. .to accept an unintentionally delayed submission of an amendment under this section.” Id.
Google attempts to neutralize these sentences through a complicated argument that distinguishes between a mandatory statutory deadline prescribed by section 120 itself, and a discretionary administrative deadline that section 120 authorizes the PTO to create. See Reply at 4-7. Google numbers the three sentences in the second paragraph of section 120 as follows:
[1] No application shall be entitled to‘the benefit of an earlier filed application under this section unless an amendment containing the specific reference to the earlier filed application is submitted at such time during the pendency of the application as required by the Director. [2] The Director may consider the failure to, submit such an amendment within that time period as a waiver of any benefit under this section. [3] The Director piay establish procedures... to accept an unintentionally delayed submission of an amendment under this section.
Id. at 4. Google explains that sentence [1] authorizes the PTO to set an administrative deadline “during the pendency of the application” by which an amendment correcting a priority chain must be submitted. Id. Google states: “This empowers the [PTO] to set an administrative deadline that can be earlier then the' statutory deadline” — the statutory, deadline being before patent issuance.' Id. Google then argues that the discretion reflected in the “may” in sentence [2], as well as the procedures for accepting “an unintentionally delayed submission” authorized by sentence [3], apply only to'failures to comply with the administrative deadline, not with the statutory deadline. According to Google, “[t]hese sentences authorize the [PTO] to accept" amendments correcting priority claims that are submitted after the.administrative deadline, but they do not change the statutory deadline of patent issuance.” Id. at 5.
This argument is not Convincing. Even assuming that Google is right to distinguish between administrative and statutory deadline's for the purposes of section 120, it does not necessarily follow that sentences [2] and [3] apply only when the amendment is submitted before the patent is issued. The textual basis for such a reading of sentence [2] is tenuous at best, [994]*994and there is nothing in sentence [3] to indicate that the procedures it authorizes may not be applied to amendments submitted post-issuance.
• Further, even if section 120 did not authorize the PTO to allow post-issuance correction of priority chains, section 255 still would. Google argues that section 265 cannot be used to fix section 120 mistakes because “certificates of correction apply only to patents, not applications,” Reply at 6 (emphasis in original). Google cites no authority for this argument, and I have not found any. Moreover, as discussed in more detail below, Google’s construction of section 255 is at odds with the Federal Circuit’s analysis in E.I. du Pont de Nemours & Co. v. MacDermid Printing Solutions, L.L.C., 525 F.3d 1353 (Fed.Cir.2008), which implicitly recognized that a certificate of correction under 35 U.S.C. § 254 can be used to fix priority chain mistakes under 35 U.S.C. § 119(e)(1). The relevant language in sections 254 and 119(e)(1) is identical to that in sections 255 and 120: both section 254 and section 255 concern “patent[s],” and both section 120 and section 119(e)(1) concern “application^].”4,5
Google’s position is further weakened by the lack of case law Google cites in support [995]*995of it. Google relies principally on Medtronic and Encyclopaedia Britannica, another case involving a chain of priority defect under section 120. These cases are clearly relevant to other aspects of Google’s argument — i.e., whether the applications for the ’091 and ’840 patents were required to identify other applications in the chain, and whether their failure to do so impacts the priority dates for the ’509, ’603, and ’436 patents. But the cases say little, if anything, about the one aspect of Google’s argument that WTI actually disputes — i.e., whether a section 255 certificate of correction may be used to correct a defective chain of priority under section 120. The patentees in Medtronic and Britannica did not seek or obtain certificates of correction, and Google identifies nothing in either decision that speaks to the interaction between sections 120 and 255. The cases do not help Google.
Meanwhile, as WTI highlights and Google does not dispute, the PTO has allowed patentees to use section 255 certificates of correction to correct section 120 priority chains since at least as early as 1976. See In Re Lambrech, 202 U.S.P.Q. 620 (1976); see also Worlds, Inc. v. Activision Blizzard, Inc., No. 12-cv-10576, 2014 WL 972135, at *9 (D.Mass. Mar. 13, 2014) (recognizing the prospective effectiveness of a section 255 certificate of correction issued by the PTO to correct a section 120 specific reference mistake); Pfizer Inc. v. Teva Pharm. U.S.A., Inc., 882 F.Supp.2d 643, 696-99 (D.Del.2012) (same); Carotek, Inc. v. Kobayashi Ventures, LLC, 875 F.Supp.2d 313, 335-36 (S.D.N.Y.2012) (same); Adrain v. Hypertech, Inc., No. 98-cv-37C, 2001 WL 740542, at *2-5 (D.Utah Apr. 18, 2001) (same). The most recent version of the Manual of Patent Examining Procedures (“MPEP”) provides that a certificate of correction under either section 255 or section 254 can be used, “with respect to 35 U.S.C. § 120 priority, to correct. . .the failure to make reference to a prior copending application” in an application filed either before November 29, 2000 or on or after November 29, 2000 and before March 16, 2013, so long as “all requirements set forth in [the relevant version of 37 C.F.R §. 1.78(a)(1)] have been met in the application which became the patent to be corrected,” and it is “clear from the record of the patent and the parent application(s) that priority is appropriate.” MPEP § 1481.03(II)(B)-(C) (9th ed. 2014) (emphasis added). This instruction plainly indicates that, insofar as the PTO is concerned, a section 255 certificate of correction can be used to correct a section 120 chain of priority defect even after patent issuance.6
[996]*996WTI’s argument is further supported by MacDermid, the one Federal Circuit decision cited by either party that is factually similar to this case. In MacDermid, the patentee filed a provisional application followed by a nonprovisional application, but due to PTO mistake, the issued patent did not reference the provisional application. 525 F.3d at 1355. The patentee sought and obtained a certificate of correction under section 254 to add a reference to the provisional application in accordance with section 119(e)(1). In upholding the effectiveness' of the certificate of correction, the Federal Circuit rejected the defendants’ argument that the mistake was the paten-tee’s and not the PTO’s. The court stated:
We hold that a lack of diligence during prosecution, at least under the facts of this case, does not convert a PTO error into an applicant error for the purpose of seeking a post-issuance certificate of correction.
It is, of course, desirable to have applicants correct the PTO’s mistakes in pending applications as soon as possible so that ■ the correct information is reflected in published applications and-issued patents. Nevertheless, nothing in [section 254] conditions eligibility for a certificate to correct PTO error on the applicant’s diligence in correcting the mistake, and the statute does not set any time limit for seeking such corrections.
Id, at 1361-62;
MacDermid is. not a perfect fit for this case, in that it concerns a certificate of correction under section 254 (as opposed to section 255) to correct a specific reference error under section 119(e)(1) (as opposed to section 120). MacDermid also does not squarely address whether a section 119(e)(1) mistake can be corrected by a section 254 certificate of correction — the court appears to have merely assumed that it can be.
Nevertheless, the similarities, between sections 254 and 255, and between sections 119(e)(1) and 120, make the case instructive here. Both sections 254 and 255. provide that the corrected “patent ... shall have the same effect and operation in law on the trial of actions for. causes thereafter arising as if the same had been originally issued in such corrected form.” 35 U.S.C. §§ 254, 55 (emphasis added). And both sections 119(e)(1) and 120 require that the “application ... contain] or [be] amended to contain a specific reference to the [provisional / earlier filed] application.” 35 U.S.C. §§ 119(e)(1), 120 (emphasis added). Despite section 254 referencing “patents” and section 119(e)(1) referencing “applications,” the Federal Circuit did not hold that a section 254 certificate of correction could not be used to fix a section 119(e)(1) mistake. To the contrary, the court implicitly recognized that it could be, and stated that section 254 “does not set any time limit for seeking.. .corrections.” MacDermid, 525 F.3d at 1361-62. Given the similarities between sections 254 and 255, and between sections. 119(e)(1) and 120, Mac-Dermid casts serious doubt on Google’s argument that a section 255 certificate of correction cannot be used to fix section 120 mistakes because “certificates of correction apply only to patents, not applications.” Reply at 6.7
[997]*997In sum, Google has not shown that a section 255 certificate of correction cannot be used to correct a defective. chain of priority under section 120. Google does not dispute that the certificates of correction for the ’091 and ’840 patents otherwise complied "with section 255. Accordingly, Google’s motion to dismiss WTI’s claims of infringement of the ’091, ’840, .’509, ’603, and ’436 patents is DENIED.
CONCLUSION
For the foregoing reasons, Google’s motion to dismiss is GRANTED IN PART and DENIED IN PART. WTI shah file an amended complaint, if any, within 20 days of the date of this Order.
IT IS SO ORDERED.
