8 Plaintiff, ORDER GRANTING MOTIONS TO 9 v. DISMISS AND STRIKE AND DENYING MOTION FOR 10 TETRAMEM, INC., ATTORNEYS’ FEES AND COSTS 11 Defendant. Re: Dkt. Nos. 28, 31

12 Pro se plaintiff Xiaohua Huang alleges that defendant TetraMem infringes U.S. Patent No. 13 RE45,259 (“the ’259 patent”), which Huang owns. This is the second action that Huang has 14 brought against TetraMem in this district alleging infringement of the ’259 patent. See Xiaohua 15 Huang v. TetraMem Inc., No. 23-cv-04936 (Huang I). Huang voluntarily dismissed Huang I on 16 January 29, 2024, before the court could decide TetraMem’s then-pending motion to dismiss the 17 amended complaint in that case. Huang filed this action asserting very similar claims less than 18 nine months later. 19 TetraMem moves to dismiss Huang’s amended complaint pursuant to Federal Rule of Civil 20 Procedure 12(b)(6) and to strike sections of it pursuant to Federal Rule of Civil Procedure 12(f). 21 Additionally, TetraMem moves for attorneys’ fees and costs pursuant to Federal Rule of Civil 22 Procedure 11. For the following reasons, the motions to dismiss and strike are granted and the 23 motion for attorneys’ fees and costs is denied. 24 LEGAL STANDARD 25 I. Rule 12(b)(6) 26 Federal Rule of Civil Procedure 8(a)(2) requires a complaint to include a “short and plain 27 statement of the claim showing that the pleader is entitled to relief.” If the complaint fails to state a 1 Dismissal is required if the plaintiff fails to allege facts allowing the Court to “draw the reasonable 2 inference that the defendant is liable for the misconduct alleged.” Ashcroft v. Iqbal, 556 U.S. 662, 3 678 (2009). “Dismissal under Rule 12(b)(6) is appropriate only where the complaint lacks a 4 cognizable legal theory or sufficient facts to support a cognizable legal theory.” Mendiondo v. 5 Centinela Hosp. Med. Ctr., 521 F.3d 1097, 1104 (9th Cir. 2008). To survive a Rule 12(b)(6) 6 motion, a plaintiff need only plead “enough facts to state a claim to relief that is plausible on its 7 face.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007). 8 In considering a Rule 12(b)(6) motion, the Court must “accept all factual allegations in the 9 complaint as true and construe the pleadings in the light most favorable” to the non-moving party. 10 Rowe v. Educ. Credit Mgmt. Corp., 559 F.3d 1028, 1029–30 (9th Cir. 2009). While legal 11 conclusions “can provide the [complaint’s] framework,” the Court will not assume they are correct 12 unless adequately “supported by factual allegations.” Iqbal, 556 U.S. at 679. Courts do not “accept 13 as true allegations that are merely conclusory, unwarranted deductions of fact, or unreasonable 14 inferences.” In re Gilead Scis. Secs. Litig., 536 F.3d 1049, 1055 (9th Cir. 2008) (quoting Sprewell 15 v. Golden State Warriors, 266 F.3d 979, 988 (9th Cir. 2001)). 16 II. Rule 12(f) 17 Federal Rule of Civil Procedure 12(f) permits a court to “strike from a pleading an 18 insufficient defense or any redundant, immaterial, impertinent, or scandalous matter.” Immaterial 19 matter is “that which has no essential or important relationship to the claim for relief or the 20 defenses being pleaded.” Fantasy, Inc. v. Fogerty, 984 F.2d 1524, 1527 (9th Cir. 1993), rev’d on 21 other grounds, 510 U.S. 517 (1994). “Scandalous material has been defined as allegations that cast 22 a cruelly derogatory light on a party or person.” Holmes v. Elec. Document Processing, Inc., 966 23 F. Supp. 2d 925, 938 (N.D. Cal. 2013) (cleaned up). “The rationale behind granting motions to 24 strike is to ‘avoid … prejudice to a party by preventing a jury from seeing the offensive matter or 25 giving the allegation any unnecessary notoriety.’” In re Valence Tech. Sec. Litig., No. C 94-1542- 26 SC, 1995 WL 274343, at *18 (N.D. Cal. May 8, 1995) (quoting 5A Charles A. Wright and Arthur 27 R. Miller, Federal Practice and Procedure § 1382, at 715 (2d ed. 1990)). Motions to strike are 1 bearing on the subject matter of the litigation.” LeDuc v. Ky. Cent. Life Ins. Co., 814 F. Supp. 820, 2 830 (N.D. Cal. 1992). The moving party has the burden to show that the allegations it hopes to 3 strike as irrelevant will cause “specific undue prejudice.” In re Facebook PPC Advert. Litig., 709 4 F. Supp. 2d 762, 773 (N.D. Cal. 2010). Ultimately, “[w]hether to grant a motion to strike lies 5 within the sound discretion of the district court.” Woods v. Google LLC, No. 5:11-cv-01263, 2018 6 WL 5292210, at *2 (N.D. Cal. Oct. 23, 2018) (cleaned up) 7 III. Rule 11 8 Federal Rule of Civil Procedure 11 allows the court to impose sanctions if it finds that a 9 lawsuit relies on frivolous legal arguments, lacks a factual basis, or has been filed “for any 10 improper purpose, such as to harass, cause unnecessary delay, or needlessly increase the cost of 11 litigation.” The “purpose of Rule 11 is to deter baseless filings.” Cooter & Gell v. Hartmarx 12 Corp., 496 U.S. 384, 393 (1990). Rule 11 seeks to achieve a balance between, “the desire[s] to 13 avoid abusive use of the judicial process and to avoid chilling zealous advocacy.” Hudson v. 14 Moore Bus. Forms, Inc., 836 F.2d 1156, 1159–60 (9th Cir. 1987). An objective standard of 15 reasonableness is applied to determine whether a litigant has met their obligations under Rule 11. 16 G.C. and K.B. Investments, Inc. v. Wilson, 326 F.3d 1096, 1110 (9th Cir. 2003). 17 ANALYSIS 18 I. Huang fails to state a claim for patent infringement. 19 Huang appears to allege direct (both literally and under the doctrine of equivalents), 20 induced, and contributory patent infringement. 21 To prevail on a claim for direct patent infringement, a plaintiff must establish ownership of 22 the patents and show that the accused infringer, without authorization, made, used, offered to sell, 23 sold, or imported the patented invention. 35 U.S.C. § 271(a). “[T]o properly plead direct 24 infringement under Twombly and Iqbal, a plaintiff must plausibly allege that a defendant directly 25 infringes each limitation in at least one asserted claim.” Scripps Rsch. Inst. v. Illumina, Inc., No. 26 16-cv-661, 2016 WL 6834024, at *5 (S.D. Cal. Nov. 21, 2016) (cleaned up). A plaintiff’s claims 27 of infringement do not satisfy “the Iqbal/Twombly standard by reciting the claim elements and 1 allegations that, when taken as true, articulate why it is plausible that the accused product infringes 2 the patent claim.” Bot M8 LLC v. Sony Corp. of Am., 4 F.4th 1342, 1353 (Fed. Cir. 2021). 3 “To find infringement under the doctrine of equivalents, any differences between the 4 claimed invention and the accused product must be insubstantial. One way of proving 5 infringement under the doctrine of equivalents is to show, for each claim limitation, that the 6 accused product performs substantially the same function in substantially the same way with 7 substantially the same result as each claim limitation of the patented product.” Brilliant 8 Instruments, Inc. v. GuideTech, LLC, 707 F.3d 1342, 1346–47 (Fed. Cir. 2013) (cleaned up). 9 To plead inducement, a plaintiff must plead that the “the alleged inducer [1] knew of the 10 patent, [2] knowingly induced the infringing acts, and [3] possessed a specific intent to encourage 11 another’s infringement of the patent.” Vita-Mix Corp. v. Basic Holding, Inc., 581 F.3d 1317, 1328 12 (Fed. Cir. 2009) (cleaned up). 13 To plead contributory infringement, a plaintiff must plead four elements: “(1) the 14 defendant sold a component or material for use in practicing the patented method; (2) the 15 component or material constitutes a material part of the invention; (3) the defendant knew that the 16 item it sold was especially made or adapted for use in infringing the patented method; and (4) the 17 item sold is not a staple article or commodity of commerce suitable for substantial noninfringing 18 use.” Sandisk Corp. v. Lexar Media, Inc., 91 F. Supp. 2d 1327, 1331 (N.D. Cal. 2000). 19 Huang fails to state a claim for patent infringement under any theory because his 20 infringement allegations—in addition to being confusing, often unintelligible, and punctuated by 21 lengthy and irrelevant digressions—are conclusory and unsupported by any specific factual 22 allegations showing why it is plausible that TetraMem’s products infringe any of the ’259 patent’s 23 claims. For example, Huang alleges that “[b]ased on the information obtained that the products 24 made by Defendant TetraMem, including but not limited to embedded ReRAM or RRAM IP, also 25 called Analog-in-ReRAM, ‘a metal-oxide based cross-point switch’, Memristor, ‘multi-level 26 RRAM’, ‘computing memristor’, ‘analog RRAM’ and chips called ‘TetraMem MX100’ and 27 Cullinan, contain integrated circuit with the function which read the claim 29 of US patent 1 have infringed and continue to infringe directly, indirectly, literally, on Doctrine of Equivalent the 2 claim 29 of the ‘RE259 patent by using the devices which infringes the claim 29 of ‘RE259 patent. 3 The Customers of the Defendant uses the function of reading and writing data and information 4 which contains the circuit and logic reading the claim 29 of the ‘RE259 patent. The using of 5 function of reading and writing data and information in accused devices are completely not a 6 staple article or commodity of commerce suitable for substantial non-infringing use.” 7 As the Federal Circuit has made clear, a plaintiff cannot state a claim for patent 8 infringement by simply “reciting the claim elements and … concluding that the accused product 9 has those elements.” Bot M8, 4 F.4th at 1353. Instead, “there must be some factual allegations that 10 … articulate why it is plausible that the accused product infringes the patent claim.” Id. Huang’s 11 complaint is devoid of any such factual allegations, and instead merely recites the elements of 12 patent infringement and asserts that TetraMem meets them. Accordingly, Huang’s complaint fails 13 to state a claim for patent infringement, and TetraMem’s motion to dismiss is granted on that 14 basis. 15 Leave to amend should generally be freely granted unless amendment would be futile. Fed. 16 R. Civ. P. 15. Having carefully considered the record, the Court concludes that leave to amend 17 would be futile here. As other courts considering some of the at least 53 patent infringement cases 18 Huang has filed in jurisdictions around the county have noted, Huang “is a sophisticated pro se 19 litigant, an engineer, and a business owner.” Huang v. Amazon.com Inc., No. 23-CV-04679, 2024 20 WL 413355, at *4 (N.D. Cal. Jan. 26, 2024); Xiaohua Huang v. Huawei Techs. Co., No. 15-cv- 21 01413, 2017 WL 1133201, at *4 (E.D. Tex. Mar. 27, 2017), aff’d, 735 F. App’x 715 (Fed. Cir. 22 2018). Despite receiving extensive notice of the deficiencies in his claims, Huang has failed to 23 remedy them. Not only has TetraMem filed multiple motions to dismiss detailing why Huang’s 24 pleadings are confusing and inadequate in both this action and Huang I, but TetraMem also sent 25 Huang a letter explaining the deficiencies in his infringement allegations after Huang’s dismissal 26 of Huang I. Despite these repeated notices, Huang has consistently failed to modify his allegations 27 in a manner that addresses the insufficiency of his allegations. 1 extensive notice of their deficiencies and in light of his prior experience in patent litigation 2 demonstrates that providing leave for further amendment would be futile. The Court therefore 3 grants TetraMem’s motion to dismiss with prejudice and without leave to amend. 4 II. Paragraphs 10 through 14 are stricken from the first amended complaint. 5 TetraMem argues that paragraphs 10–14 of the amended complaint should be stricken 6 because they are baseless, improper, derogatory, unnecessary, and irrelevant to Huang’s patent 7 infringement claims. 8 These paragraphs accuse defense counsel of various forms of misconduct in this case and 9 in Huang I. They also allege that defense counsel and judges in Huang’s other patent lawsuits 10 engaged in various form of misconduct. 11 These allegations are immaterial to Huang’s claims for patent infringement. They do not 12 plead facts relevant to the elements of direct, induced, or contributory patent infringement. 13 Further, they risk harming TetraMem’s public reputation. Accordingly, the Court grants 14 TetraMem’s motion to strike. 15 III. Attorneys’ fees and costs 16 TetraMem argues that Huang’s repeated assertion of the same baseless claims in this 17 lawsuit and Huang I despite notice of their deficiencies constitutes harassment or, “at the very 18 least, … is calculated to pressure TetraMem into reluctantly entering a settlement agreement.” 19 TetraMem argues that Huang’s conduct in this case must be interpreted in light of the 53 other 20 patent lawsuits Huang has filed and Huang’s repeated judicial admonishments for his vexatious 21 conduct, “bad faith and abuse of the judicial process,” and use of litigation to “harass 22 defendant[s].” Xiaohua Huang v. Genesis Glob. Hardware, Inc., No. 2:20-cv-1713, 2020 WL 23 7360582, at *5 n.5 (E.D. Cal. Dec. 15, 2020); Huang v. Huawei Techs. Co., No. 2:15- cv-01413, 24 2017 WL 1133201, at *3 (holding that Huang’s bad faith conduct justified awarding defendant’s 25 attorneys’ fees and costs, which ultimately totaled $604,036.71). In Huang v. Huawei Techs. Co., 26 for example, the court determined that Huang’s case had been “frivolous from the outset,” and his 27 “motive all along was to extract a settlement by whatever means necessary.” No. 2:15- cv-01413, 1 TetraMem should therefore be awarded its attorneys’ fees and costs as a sanction under Rule 11. 2 TetraMem also contends that the two money orders for $1,000.00 each that Huang sent to 3 TetraMem’s counsel—which were accompanied by a note that said, “The enclosed is for you 4 upfront, the other will be after the settlement.”—constituted a bribe, and that Huang knew this 5 conduct was impermissible because he had been warned about similar conduct in another case. See 6 Huang v. Trifecta Networks, LLC, No. 21-cv-01637, at *1 (M.D. Fla. Dec. 20, 2022) (warning 7 Huang that sending a Christmas card to the court with $2,500 in money orders was “not 8 appropriate” and that similar conduct in the future could lead to sanctions). 9 Huang’s complaint certainly borders on frivolous or harassing for the reasons that 10 TetraMem describes. But Huang’s pro se status counsels in favor of resolving all doubts in his 11 favor. “Although Rule 11 applies to pro se plaintiffs, the court must take into account a plaintiff’s 12 pro se status when it determines whether the filing was reasonable.” Warren v. Guelker, 29 F.3d 13 1386, 1390 (9th Cir. 1994) (per curiam); cf. id. (quoting Kurkowski v. Volcker, 819 F.2d 201, 204 14 (8th Cir. 1987) (“We recognize that pro se complaints are read liberally, but they still may be 15 frivolous if filed in the face of previous dismissals involving the exact same parties under the same 16 legal theories.”). Taking into account Huang’s pro se status, and interpreting the complaint 17 liberally, it does not rise to a level warranting sanctions under Rule 11. Huang is cautioned, 18 however, that reasserting any claims against TetraMem similar to those asserted here will likely 19 lead to Rule 11 sanctions given that his claims have been dismissed with prejudice. See Profita v. 20 Andersen, No. CV 18-00286-PA, 2018 WL 4199214 (C.D. Cal. Aug. 8, 2018) (declining to 21 impose Rule 11 sanctions on plaintiff due to his pro se status but cautioning him that “future 22 attempts to file a federal lawsuit in this Court on the grounds set forth in the amended complaint 23 may result in the imposition of sanctions”), report and recommendation adopted by No. CV 18- 24 00286-PA, 2018 WL 4191611 (C.D. Cal. Aug. 31, 2018), aff’d, 771 F. App’x 414 (9th Cir. 2019) . 25 CONCLUSION 26 For the foregoing reasons, TetraMem’s motions to dismiss and to strike portions of 27 Huang’s complaint are granted. Because the Court finds that amendment would be futile, the 1 for attorneys’ fees and costs is denied. 2 IT IS SO ORDERED. 3 Dated: May 7, 2025 May be~ 5 P.
