8 Plaintiff,

ORDER DENYING DEFENDANT’S

9 v. MOTION FOR LEAVE TO AMEND

ANSWER, INVALIDITY

10 POLYCOM, INC., CONTENTIONS, AND TO COMPEL

PRODUCTION

11 Defendant. Docket No. 164 12 13 14 I. INTRODUCTION 15 Plaintiff FullView, Inc. (“FullView”) filed this lawsuit against Defendant Polycom, Inc. 16 (“Polycom”) alleging patent infringement. FullView is the owner of a group of patents disclosing 17 technology involving the creation of composite images—i.e., a device capable of producing 18 panoramic photographs. Now pending before the Court is a single motion by Polycom 19 encompassing three requests: (1) Leave to amend its answer to add a claim for inequitable conduct 20 by FullView; (2) Leave to amend its invalidity contentions; and (3) An order compelling FullView 21 to comply with Patent Local Rules 3-2(a)-(b). Docket No. 164 (“Motion”). 22 For the following reasons, the Court DENIES all three requests and, thus, the motion in its 23 entirety. 24 II. BACKGROUND 25 A. Factual Background 26 FullView, the owner of the ‘143 Patent and U.S. Patent No. 6,700,711 (“the ‘711 Patent”), 27 asserts Polycom infringes on its patents. The ‘143 Patent relates to panoramic viewers used in 1 a compact “omni-directional or panoramic viewer” based on three primary components. Docket 2 No. 75, Exh. B (“‘143 Patent”), claims 10-12. 3 First, there is at least “one pyramid shaped element having a plurality of reflective side 4 facets facing in different directions.” Id. at 16:23-25. Second, there are image-processing devices, 5 such as cameras, that are oriented around the pyramid to provide a continuous 360-degree view of 6 the area. Id. at 2:3-5; 16:20-22. Each camera is pointed towards a different side of the mirrored 7 pyramid and as a result, these cameras have a virtual optical center positioned within the pyramid. 8 Id. at 2:16-20; 16:26- 28. Third, there is a “support member” (i.e., a post) that intersects the 9 pyramid shaped object’s “inner volume.” Id. at 11:54-56; 16:30-34. Some of the cameras are also 10 attached to this support member. Id. at 11:60-63; 16:30-34. 11 B. Procedural Background 12 1. Inter Partes Review History 13 In January 2012, Polycom filed an inter partes reexamination (IPR) challenging the 14 validity of the ‘711 Patent based on obviousness grounds. See SAC ¶ 18; see also Polycom, Inc. v. 15 FullView, Inc., 767 F. App’x 970, 983 (Fed. Cir. 2019). On January 4, 2017, the Patent Trial and 16 Appeal Board (PTAB) upheld the ‘711 Patent as valid; the U.S. Court of Appeals for the Federal 17 Circuit affirmed the PTAB’s decision on April 29, 2019. SAC ¶¶ 21, 23. On January 31, 2019, 18 Polycom sought an IPR of the ‘143 Patent. Id. ¶ 24. However, the PTAB denied this petition as 19 well as Polycom’s request for rehearing on September 10, 2019. Id. ¶ 25. 20 2. Litigation History 21 On January 23, 2018, FullView filed its first complaint. Docket No. 1. On July 2, 2020, 22 FullView filed its second amended complaint alleging: infringement of both the ‘711 and ‘143 23 Patents under 35 U.S.C. § 271 by (1) direct infringement; (2) infringement by inducement; and (3) 24 infringement via the doctrine of equivalents. SAC ¶¶ 59-66. Polycom moved to dismiss the 25 second amended complaint’s claims pertaining to the ‘711 Patent because that patent (a) was 26 directed at nonpatentable subject matter and (b) sought to protect an abstract idea without an 27 inventive concept. Id. The Court granted Polycom’s motion to dismiss on both grounds. Docket 1 sought to add two additional patents to the litigation and to amend the infringement contentions to 2 assert claims from those patents. Docket No. 144. 3 Accordingly, only claims 10 through 12 of the ‘143 Patent are currently in dispute in this 4 litigation. See Docket No. 110 (“Joint Statement”) at 2; SAC ¶ 47. On April 5, 2021, the Court 5 issued an order construing the disputed terms of the ’143 Patent. Docket No. 137. 6 C. Polycom’s Factual Assertions Relevant to this Motion 7 In support of the instant motion, Polycom asserts additional facts regarding the parties’ 8 actions and conduct before and during the litigation that are allegedly relevant to deciding this 9 motion. 10 Polycom asserts that after the Court ordered the parties to stipulate to fact discovery 11 deadlines on August 10, 2021, Docket No. 154, Polycom interviewed Mr. Kurtis Keller, a research 12 engineer at the University of North Carolina, who “indicated that he had built a panoramic 13 viewing device” (the “UNC device”) allegedly “meeting all the limitations in the asserted claims 14 of the ’143 Patent before the August 28, 1998 filing date of the application leading to the ’143 15 Patent”. Motion at 11. The UNC device was “operationally displayed on July 29, 1997 at the 16 University of Utah, and a non-operational version was displayed August 3–8, 1997 in Los 17 Angeles, CA” at a “convention attended by over 48,000 people.” Id. Polycom contends the UNC 18 device anticipates the ‘143. Id. at 32. 19 Keller apparently provided Polycom’s counsel with a 1999 paper written by Majumder, 20 which described the UNC device as well as previously known panoramic viewing devices. The 21 Majumder paper included a citation to a technical memorandum written in 1996 (“Nalwa 1996”) 22 by Dr. Vishvjit Nalwa, the named inventor of the asserted patent ‘143 at issue in this case. Id. at 23 11-12. According to Polycom, Nalwa 1996 “includes several figures that are substantially similar 24 to the figures in the ’143 Patent, as well as a photograph of a prototype device that appears to meet 25 all limitations of the asserted claims of the ’143 Patent.” Id. at 11. In support of this claim, 26 Polycom cites Figure 18 of the paper, which shows “[a] mirrored pyramid” that “was constructed” 27 and includes “individual mirrors of the pyramid [that] are of polished steel” in addition to “four 1 reproduced below. 2 3 4 □□ 5 7 □□□ a 6 \ . > aa 7 r 7 8 " ar 48 9 1 be x: 2 Ej el 10 11 % Bleck

15 16 □□ Figure 18 Photograph of implemented mirrored 2 17 pyramid with attached CCD cameras.

4 18 || Docket No. 164-6 at 31. Polycom contends Nalwa 1996 also anticipates the ‘143 Patent. Motion 19 at 32. 20 Polycom concedes that it was previously aware that Nalwa 1996 was created as a 21 Technical Memorandum for Bell Labs, but Polycom contends it did not know that the paper “was 22 publicly available before August 28, 1997 [the critical date for the ‘143 patent application], so as 23 II to qualify as prior art for the ‘143 patent under Section 102(b) of the Patent Act.” However, 24 Polycom contends it was only when it was prompted by the 1999 Majumder article’s citation to 25 || Nalwa 1996 to “revisit whether Nalwa 1996 was publicly available before August 18, 1997,” 26 || Motion at 12-13, thus excusing its failure to assert Nalwa 1996 in its invalidity contentions. 27 Polycom also concedes that “one of the prior art references Polycom cited in its Invalidity 28 |! Contentions” — published in 1998 (““Yamazawa 1998”) — cited to Nalwa 1996. However, Polycom

1 contends that before it served its invalidity contentions, it was “unable to find a library cataloged 2 version of the 1996 memorandum.” Id. at 12. It was only after seeing Nalwa 1996 cited in the 3 1999 Majumder article that Polycom renewed its investigative efforts which enabled it to discover 4 that Nalwa 1996 was publicly available before August 28, 1997, the critical application date for 5 the ‘143 patent application. Id. at 13. 6 Polycom contends Dr. Nalwa engaged in inequitable conduct. Despite public disclosure 7 before the critical date, a year before his patent application was filed, Dr. Nalwa did not disclose 8 Nalwa 1996 to the Patent Officer during the prosecution of the ‘143 Patent. Id. Similarly, 9 Polycom contends that FullView’s failure to disclose Nalwa 1996 during initial disclosures 10 violated Rule 3-2(a). And, Polycom argues, Dr. Nalwa belatedly revealed in his response to 11 Polycom’s interrogatories that “thousands of individuals worldwide became aware of the 12 invention between 1995-1998. Id. In Polycom’s telling, “FullView’s [interrogatory] responses 13 thus confirmed Nalwa 1996’s public availability before August 28, 1997” and “[d]espite its 14 misrepresentations to the Patent Office and to Polycom, this is the first time Dr. Nalwa and 15 FullView admitted that Nalwa 1996 was publicly available before the critical date.” Id. 16 Finally, Polycom accuses FullView of a decades-long conspiracy and fraud that it contends 17 renders the ‘143 Patent unenforceable:

18 Despite admitting under oath that Nalwa 1996 described the ’143 Patent’s invention and having personal knowledge that Nalwa 1996 19 was publicly available prior to the priority date of the ’143 Patent, Dr. Nalwa and FullView withheld this key document, authored by 20 Dr. Nalwa, from the Patent Office. Dr. Nalwa and FullView withheld this key document, when required to disclose it and 21 relevant facts related to it, pursuant to this Court’s rules, from Polycom. Indeed, instead of coming clean on their very own prior 22 art of which there can be no doubt they were aware, Dr. Nalwa and FullView have reaped rewards from their misconduct licensing the 23 ’143 Patent both to Microsoft and then to Polycom and then bringing this suit to try to recover even more money from Polycom. 24 Despite years of benefitting from the fruits of their misconduct, 25 FullView only disclosed the existence of this key evidence after they were emboldened by the fact that certain deadlines had passed in 26 this case. FullView now asks this Court to elevate procedure over substance (and indeed justice) and allow FullView to escape the 27 ramifications of its actions. disclosure from the Patent Office, they committed fraud on the same 1 and the ’143 Patent should be held unenforceable. 2 Motion at 8. 3 Based on these assertions, Polycom seeks leave from the Court to amend its answer to 4 allege a counterclaim of inequitable conduct by FullView, amend its invalidity contentions to 5 include information about Nalwa 1996 and public use of the UNC device described in Majumder 6 1999, and to compel FullView to comply with Patent Local Rule 3-2 by completing its disclosure 7 of relevant materials. 8 D. FullView’s Responses to Polycom’s Assertions 9 FullView responds to Polycom’s assertions by suggesting that Polycom’s story of its 10 recent discovery of Nalwa 1996 does not make logical sense, nor is it relevant to the claims at 11 issue in this case. 12 First, FullView focuses on Polycom’s concession that Polycom cited Yamazawa 1998 as a 13 prior art in its Invalidity Contentions; the Yamazawa article in turn cited Nalwa 1996. Docket No. 14 168 (“Opp.”) at 8. FullView contends that Polycom has long-known that Nalwa 1996 was cited in 15 a paper published in 1998 (and even referred to that 1998 article their invalidity contentions). 16 Hence, there is no basis for Polycom’s contention that its recent discovery of the 1999 Majumder 17 article was a revelatory moment for Polycom to investigate whether Nalwa 1996 was in circulation 18 before the critical date of August 28, 1997. Id. As FullView puts it, “Why would the Majumder 19 article . . . prompt a course of action that Yamazawa 1998 did not prompt?” Id. In light of 20 Polycom’s longstanding knowledge about the existence of Nalwa 1996, FullView argues there 21 was no basis for Polycom’s putative inability to find out that Nalwa 1996 was in circulation prior 22 to the 1997 patent application date. Indeed, as FullView points out, Nalwa 1996 has been publicly 23 available on FullView’s website for over a decade, that every page of the publicly-available 24 document had a stamp showing that copyright date in 1996. Further, FullView contends a simple 25 search on Google, Google Scholar, Semantic Scholar, or even the PTO’s patent search engine 26 show that the paper was in the public domain since before the critical date. Opp. at 5, 10.1 27 1 Second, FullView contends that Polycom’s assertions that FullView has engaged in 2 inequitable conduct and been engaged in a decades-long fraud on the PTO, this Court and the 3 public are meritless. Specifically, FullView explains that nothing in Nalwa 1996 discloses the 4 invention in the ‘143 Patent at issue here. FullView notes that the ’143 Patent is closely related to 5 and includes all the apparatus-related disclosures of the ’711 Patent. Opp. at 11 (“In fact, the first 6 13 figures of the ’143 Patent are from the ’711 Patent and not from Nalwa 1996. The inclusion of 7 substantially all the apparatus-related disclosures of the ’711 Patent in the ’143 Patent is hardly 8 unexpected, as each of the claims in the ’143 Patent represents an improvement on the inventions 9 included in the ’711 Patent, which preceded Nalwa 1996.”); Docket No. 75, Exh. B (‘143 Patent) 10 at 1-2. The ‘711 Patent application was filed on November 30, 1995, before the publication of 11 Nalwa 1996. See Docket No. 1, Exh. A (‘711 Patent) at 2; Docket No. 168-2 (“Nalwa Decl.”) at ¶ 12 1. Hence, the relevant question is whether anything in Nalwa 1996 disclosed elements of the 13 patented invention of the ’143 Patent that is not also disclosed in the ’711 Patent. Opp. at 10. 14 Polycom does not address this issue and thus fails to demonstrate Nalwa 1996 disclosed anything 15 new. 16 More centrally, FullView contends that nothing in Nalwa 1996 discloses the invention in 17 Patent ‘143. Claim 10 of the ‘143 Patent (at issue in this case) is described as follows:

18 10. A panoramic viewing apparatus, comprising:

19 plurality of image processing devices, each having an optical center and a field of view; 20 a pyramid shaped element having a plurality of reflective side facets 21 facing in different directions, each of at least two of the plurality of reflective side facets redirecting a field of view of one of the 22 plurality of image processing devices to create a plurality of virtual optical centers; 23 and a support member intersecting an inner volume of the 24 pyramid shaped element, the pyramid shaped element being secured to the support member and the plurality of image processing 25 devices being secured to the support member. 26 ‘143 Patent at 16:20-16:35 (emphasis added). And claim 12, the other claim at issue in this case, 27 1 is “the panoramic viewing apparatus of claim 10, wherein the support member is hollow.” Jd. at 2 16:38. The ‘143 Patent exemplifies claims 10-12 through its Figure 17 which illustrates the 3 inclusion of the “supporting member.” See id. at 11:43-12:19. 4 ° a30 6 818 FIG. 17 | Lt) 816 “Cameras 810” are the 7 ———— ‘image processing g B10 devices” secured to “a Every “inner volume B14 support member” that shaped element” is = — B12 10 wholly within this 7 To 806 “Reflective pyramid shaded area | \ UZ Oh is “the pyramid 11 " i shaped element” Hollow tube soe 's | 800 secured to “a support 12 __@ support member member” that is intersecting an inner i | “hollow tube 804” B volume of the 808 | 804 pyramid shaped I t” 4 cee 80 ae 524 820“ | J 802 15 818 16

2 17 || Docket No. 168-2 (“Nalwa Decl.”) {| 15; see also ‘143 Patent at 11:43-12:19 (“... Reflective Z 18 || pyramid 800 is mounted to stand or post 802 using a support member such as hollow tube 804. 19 || The pyramid is secured to hollow tube 804 at vertex end 806. The hollow tube is secured to stand 20 802 by angle brackets 808. Hollow tube 804 extends beyond vertex end 806 so that cameras 810 21 may be supported by tube 804. The cameras are mounted to tube 804 by strap or belt ... It should 22 || be noted that hollow tube 804 may be replaced with a solid support member ... It is also possible 23 || to invert the viewer of FIG. 17 so that the viewer is supported by end 830 of tube 804.”). 24 Importantly, Nalwa 1996 does not depict an invention that includes or refers in any way to 25 “a support member intersecting an inner volume of the pyramid shaped element,” not to a “support 26 || member [that] is hollow.” Jd. This is significant. Polycom’s filings during the IPR Proceedings 27 clearly shows that Polycom is aware that the new aspect of the ‘143 Patent was the addition of a 28 || “support member”:

1 Nalwa is an earlier European patent application by the inventor of the °143 patent and discloses a panoramic viewing system that is 2 identical to the single-polyhedral structure described in the ’143 patent. Nalwa’s disclosure is included in the ’143 patent; Figures 1- 3 10 of Nalwa are the same as Figures 1-10 of the ’143 patent, including the single-polyhedral embodiments in Figures 2-6. (Ex. 4 1006, 1:10-5:6, Figs. 2-6). The only difference between Nalwa and the challenged claims of the ’143 patent is the addition of a 5 support member [with the claimed intersection]. (Ex. 1002 § 44). 6 Docket No. 118-1, Exhibit C at 13 (emphasis added). 7 The only evidence in support of Polycom’s argument that Nalwa 1996 discloses the ‘143 8 Patent amounts to a citation to a single image in Nalwa 1996: Figure 18 (reproduced above). 9 Motion at 11-12, 25-26. But, nothing in Figure 18 or elsewhere in Nalwa 1996 mentions, 10 || describes or refers to a “support member intersecting an inner volume of the pyramid shaped 11 element.” 12 Polycom asserts that Figure 18 depicts a support member, quoting the language of the ‘143

13 || Patent, and then incorporates a zoomed-in image Figure 18, which Polycom proclaims “suggest[s]

v 14 || that the pyramid shaped element is attached or fastened to a support member that intersects the

15 inner volume of the pyramid shaped element.” Motion at 26. 16

= 17

Z 18

19 yy 20 21 22 23 24 25 Id. Setting aside the fact that Polycom does not point to anything in the text of Nalwa 1996 that 26 supports what Polycom insinuates, Polycom’s claim that Figure 18 “suggest[s]” that there is a 27 “support member that intersects the inner volume of the pyramid shaped element” requires x-ray 28 vision in order to be credited. Figure 18 shows the exterior of a device, with no indication of how

1 the interior is constructed. Indeed, it appears that post to which the cameras are attached is 2 connected to a flange on the pyramid shaped element, not a support member that runs through the 3 pyramid. 4 Moreover, FullView objects to Polycom’s selective quoting of FullView’s interrogatory 5 responses to suggest that FullView engaged in a decades-long fraud. As FullView argues:

6 Polycom quotes FullView’s response to Polycom’s Interrogatory No. 1 several times — at 8, 13, 14, 27 — but only partially, so that it 7 loses context:

8 Dr. Nalwa stated, under oath, that “[t]housands of individuals worldwide became aware of the invention” 9 between “1995–1998 and beyond” and “saw a prototype of the invention or read the technical memorandum that 10 described it”

11 As the accompanying Nalwa Declaration explains in detail at ¶¶ 18– 25, the “invention” being referred to above, in context, is that of the 12 ’711 Patent. Polycom could not have misunderstood this because Dr. Nalwa also said in the same response that, “The asserted claims (of 13 the ’143 patent) were reduced to practice in 1999-2000: A product that implemented these claims was sold to USC around May 2000.” 14 In verifying FullView’s responses, Dr. Nalwa also affirmed under oath in response to Polycom’s Interrogatory No. 4 that “[b]efore the 15 filing of the patent application on August 28, 1998, the inventor and his employer at the time, Bell Laboratories, kept the invention [of 16 the asserted claims] in strict confidence.” 17 Opp. at 12. 18 Finally, FullView points out that Polycom fails to demonstrate due diligence in discovering 19 the UNC device more than a year after it filed its invalidity contention. FullView argues that 20 Polycom also failed to exercise diligence in asserting Nalwa 1996 for the first time in the pending 21 motion on October 19, 2021. FullView, thus, argues that Polycom is not entitled to amend its 22 invalidity contentions. Id. 23 III. LEGAL STANDARDS 24 A. Amendment of Pleadings 25 Federal Rule of Civil Procedure 15(a) provides that a court “should freely give leave [to 26 amend pleadings] when justice so requires.” However, “the grant or denial of a subsequent 27 opportunity to amend is within the discretion of the district court.” Foman v. Davis, 371 U.S. 178, 1 discretion, the Supreme Court has stated that:

2 [i]n the absence of any apparent or declared reason—such as undue delay, bad faith or dilatory motive on the part of the movant, 3 repeated failure to cure deficiencies by amendments previously allowed, undue prejudice to the opposing party by virtue of 4 allowance of the amendment, futility of amendment, etc.—the leave sought should, as the rules require, be “freely given.” 5 6 Id. Courts have held that “the crucial factor is the resulting prejudice to the opposing party.” 7 Howey v. United States, 481 F.2d 1187, 1190 (9th Cir. 1973). 8 In determining undue delay the question is “whether the moving party knew or should 9 have known the facts and theories raised by the amendment in the original pleading.” Jackson v. 10 Bank of Hawaii, 902 F.2d 1385, 1388 (9th Cir. 1990). Indeed, “amendments to assert new 11 theories are not reviewed favorably when the facts and the theory have been known to the party 12 seeking amendment since the inception of the cause of action.” Acri v. Int’l Ass’n of Mach. & 13 Aerospace Workers, 781 F.2d 1393, 1398 (9th Cir. 1986) (internal citations omitted). Further, a 14 motion to amend may be denied on grounds of futility of the proposed amendments irrespective of 15 other factors. See Hoang v. Bank of Am., N.A., 910 F.3d 1096, 1103 (9th Cir. 2018). 16 B. Inequitable Conduct 17 To state a claim for inequitable conduct, a party must allege that “(1) an individual 18 associated with the filing and prosecution of a patent application made an affirmative 19 misrepresentation of a material fact, failed to disclose material information, or submitted false 20 material information; and (2) the individual did so with a specific intent to deceive the PTO.” 21 Exergen Corp. v. Wal-Mart Stores, Inc., 575 F.3d 1312, 1327 n.3 (Fed. Cir. 2009) (internal 22 citation omitted). Allegations of inequitable conduct must be pleaded with particularity pursuant 23 to Federal Rule of Civil Procedure 9(b), which requires that the pleadings “identify the specific 24 who, what, when, where, and how of the material misrepresentation or omission committed before 25 the PTO.” Id. at 1328. 26 C. Amendment of Invalidity Contentions 27 Patent Local Rule 3-6 governs the process for any amendment of infringement contentions: Contentions may be made only by order of the Court upon a timely 1 showing of good cause. Non-exhaustive examples of circumstances that may, absent undue prejudice to the non-moving party, support a 2 finding of good cause include:

3 (a) A claim construction by the Court different from that proposed by the party seeking amendment; 4 (b) Recent discovery of material, prior art despite earlier diligent 5 search; and

6 (c) Recent discovery of nonpublic information about the Accused Instrumentality which was not discovered, despite diligent efforts, 7 before the service of the Infringement Contentions.

8 The duty to supplement discovery responses does not excuse the need to obtain leave of court to amend contentions. 9 10 The Patent Local Rules “require parties to state early in the litigation and with specificity 11 their contentions with respect to infringement and invalidity.” O2 Micro Int’l, Ltd. v. Monolithic 12 Power Sys., Inc., 467 F.3d 1355, 1359 (Fed. Cir. 2006). The purpose of the Patent Local Rules “is 13 to ensure early crystallization of the parties’ theories, and specifically, to place the burden on the 14 plaintiff to quickly decide on and disclose the contours of its case.” OpenTV, Inc. v. Apple Inc., 15 No.15-cv-02008-EJD-NC, 2016 WL 3196643, at *3 (N.D. Cal. June 9, 2016). Thus, amendments 16 to a party’s contentions require a showing of good cause. See Pat. L.R. 3-6. 17 The moving party bears the burden of establishing diligence. O2 Micro, 467 F.3d at 1355. 18 Where the moving party is unable to show diligence, there is “no need to consider the question of 19 prejudice,” although a court in its discretion may elect to do so. See id. at 1368 (affirming district 20 court's denial of leave to amend upon finding the moving party was not diligent, without 21 considering the question of prejudice to the non-moving party). “If the court finds that the moving 22 party has acted with diligence, it must then determine whether the nonmoving party would suffer 23 prejudice if the motion to amend were granted.” Apple Inc. v. Samsung Elecs. Co. Ltd, No. 12- 24 cv0630-LHK (PSG), 2013 WL 3246094, at *1 (N.D. Cal. June 26, 2013) (internal quotation marks 25 omitted). 26 The Court may also consider “the relevance of the newly-discovered prior art, whether the 27 request to amend is motivated by gamesmanship, [and] the difficulty of locating the prior art.” 1 2622794, at *2 (N.D. Cal. July 1, 2008). 2 D. Patent Local Rules 3-2(a)-(b) 3 Patent Local Rules 3-2(a)-(b), Document Production Accompanying Disclosure provide 4 the following:

5 With the “Disclosure of Asserted Claims and Infringement Contentions,” the party claiming patent infringement shall produce 6 to each opposing party or make available for inspection and copying: 7 (a) Documents (e.g., contracts, purchase orders, invoices, 8 advertisements, marketing materials, offer letters, beta site testing agreements, and third party or joint development agreements) 9 sufficient to evidence each discussion with, disclosure to, or other manner of providing to a third party, or sale of or offer to sell, or any 10 public use of, the claimed invention prior to the date of application for the patent in suit. A party’s production of a document as 11 required herein shall not constitute an admission that such document evidences or is prior art under 35 U.S.C. § 102; 12 (b) All documents evidencing the conception, reduction to practice, 13 design, and development of each claimed invention, which were created on or before the date of application for the patent in suit or 14 the priority date identified pursuant to Patent L.R. 3-1(f), whichever is earlier[.] 15 16 Id. 17 IV. ANALYSIS 18 A. Overview 19 Polycom’s motion raises four questions for the Court: 20 1. Should Polycom be granted leave to amend its answer under Fed. R. Civ. P. 15 to 21 assert a counterclaim that the non-disclosure of Nalwa 1996 by FullView to the 22 patent office during the prosecution of the ’143 Patent constituted inequitable 23 conduct? 24 2. Has Polycom provided good cause to be permitted to amend its Invalidity 25 Contentions to include Nalwa 1996? 26 3. Did FullView violate Patent Local Rules 3-2(a) and (b) by not including Nalwa 27 1996 in the documents it produced with its Infringement? 1 Contentions to allege third party “public use” of the UNC device (described in 2 Majumder 1999) before the critical date of the ’143 Patent? 3 On the first two questions, the Court’s analysis begins by assessing whether Polycom 4 exercised diligence in discovering and asserting Nalwa 1996. For the reasons explained below, 5 the Court finds that Polycom was not diligent, and, thus, the answer to the first two questions is 6 no. Furthermore, on the first and third questions, the Court determines that Polycom has not 7 alleged facts sufficient to state a claim for inequitable conduct. Nor has Polycom alleged enough 8 to show that FullView violated Patent Local Rule 3-2. Finally, as to the fourth question, the Court 9 concludes that Polycom fails to demonstrate due diligence and, thus, is not given leave to amend 10 its invalidity contentions. 11 B. Polycom Has Not Demonstrated Diligence in Discovering and Asserting Nalwa 1996 12 A threshold question relevant to whether Polycom should be granted leave to amend its 13 answer to include a claim of inequitable conduct and to amend its invalidity contentions to assert 14 Nalwa 1996 is whether Polycom exercised diligence in discovering and asserting the article. See 15 Acri, 781 F.2d at 1398 (“[A]mendments to assert new theories are not reviewed favorably when 16 the facts and the theory have been known to the party seeking amendment since the inception of 17 the cause of action.”); O2 Micro, 467 F.3d at 1355 (moving party bears the burden of establishing 18 diligence to amend invalidity contentions). Polycom’s concession that it was aware of Nalwa 19 1996 before it served it Invalidity Contentions on August 31, 2020 because Nalwa 1996 was cited 20 to by Yamazawa 1998 is enough to end the inquiry. Motion at 12. 21 Polycom has not provided any good excuse for its failure to cite Nalwa 1996 as prior art in 22 its invalidity contentions on August 31, 2020. Polycom concedes it was aware of Nalwa 1996 23 based on its inclusion of Yamazawa 1998 in its invalidity contentions on August 31, 2020 and that 24 it knew Nalwa 1996 was publicly available on FullView’s website for many years prior to the 25 commencement of this litigation. Id. Yet Polycom waited until October 19, 2021 to move to 26 amend its answer and invalidity contentions. 27 Polycom’s assertions that it repeatedly and diligently searched but was unable to determine 1 August 28, 1997 lacks credibility. Polycom provides no evidence of what these assertedly 2 repeated and diligent searches involved. In contrast, FullView specifically contends that a search 3 on Google Scholar, Semantic Scholar or the PTO website shows that Nalwa 1996 was cited in a 4 patent application filed prior to the critical date for the ‘143 Patent. Polycom provides no response 5 nor does it dispute FullView’s claim about the ease with which Polycom could have discovered 6 that Nalwa 1996 was publicly available before the critical date. The Court cannot conclude that 7 Polycom demonstrated diligence in its discovery and assertion of Nalwa 1996, and, thus, denies 8 Polycom’s motion for leave to amend its invalidity contentions to include Nalwa 1996. See O2 9 Micro, 467 F.3d at 1368. 10 Additionally, Polycom’s lack of diligence to discover Nalwa 1996 suggests that Polycom 11 should have known about the alleged inequitable conduct when it filed its answer in July 2020. 12 Yet, Polycom did not attempt to amend its answer herein until October 19, 2021. This undue 13 delay of over one-year weighs against Polycom’s request for leave to amend its answer. See Acri, 14 781 F.2d at 1398 (“[A]mendments to assert new theories are not reviewed favorably when the 15 facts and the theory have been known to the party seeking amendment since the inception of the 16 cause of action.”). Although this factor weighs against Polycom’s request for leave to amend its 17 answer, it is not dispositive; the Court must address whether it would be futile for Polycom to 18 amend its answer. See Foman, 371 U.S. at 182; Hoang, 910 F.3d at 1103. 19 C. Polycom Fails to Allege Facts or Provide Evidence Sufficient to State a Claim for 20 Inequitable Conduct or to Demonstrate That FullView Violated Patent L.R. 3-2 21 Polycom seeks leave to amend its answer to assert a counterclaim of inequitable conduct. 22 To state a claim for inequitable conduct, Polycom must allege that “(1) an individual associated 23 with the filing and prosecution of a patent application made an affirmative misrepresentation of a 24 material fact, failed to disclose material information, or submitted false material information; and 25 (2) the individual did so with a specific intent to deceive the PTO.” Exergen Corp., 575 F.3d at 26 1327 n.3 (Fed. Cir. 2009) (internal citation omitted). Polycom fails to allege facts that satisfy 27 these two elements, and thus, has not shown that it would be able to state a claim for inequitable 1 demonstrated violation of Patent L.R. 3-2 by FullView. 2 Central to Polycom’s theory of inequitable conduct is its allegation that Nalwa 1996 3 discloses, anticipates or renders obvious the patented inventions of the ‘143 Patent. But as 4 explained above, Polycom fails to demonstrate Nalwa 1996 discloses the ‘143 Patent. Indeed, 5 Polycom declined to address whether Nalwa 1996 discloses anything about the ‘143 Patent not 6 already disclosed by the ‘711 Patent or any other prior art that the ‘143 Patent application 7 disclosed. Polycom, thus, has waived any such argument to the contrary. 8 Moreover, Polycom’s allegation that FullView’s interrogatory response reveals that Dr. 9 Nalwa attempted to sell and publicly showed the invention patented in ‘143 Patent to thousands of 10 people before the critical date in 1997 lacks merit. Motion at 8. Polycom selectively quotes from 11 the interrogatory response, which leaves out the context that Dr. Nalwa described the iterative 12 process by which he developed the technology included in the ‘143 Patent, beginning with the first 13 device which he filed a patent for in 1995 – the ‘711 Patent. See Docket No. 164-2 at 5-6. In the 14 same response, Dr. Nalwa stated under oath that, “Every art with a bearing on the patent 15 application for the ‘143 patent application for the ‘143 Patent that came to the attention of the 16 inventor or his patent attorneys was disclosed to the patent office” and that the “asserted claims 17 were reduced to practice in 1999-2000.” Id. Polycom failed to account for or address the context 18 surrounding Dr. Nalwa’s interrogatory response. 19 Thus, Polycom has not alleged facts sufficient to demonstrate the first prong of inequitable 20 conduct before the PTO – that FullView “made an affirmative misrepresentation of a material fact, 21 failed to disclose material information, or submitted false material information.” Exergen Corp., 22 575 F.3d at 1327 n.3. 23 Polycom also fails to satisfy the second prong of inequitable conduct: Polycom has not 24 alleged facts sufficient to show that any failure to disclose was made with “a specific intent to 25 deceive the PTO.” Id. Polycom alleges no facts establishing Dr. Nalwa’s specific intent to 26 deceive the PTO. Having disclosed the ‘711 Patent and dozens of other works of prior art in the 27 ‘143 Patent application, why would Dr. Nalwa deliberately conceal Nalwa 1996, particularly since 1 prior application for the ‘711 patent? And if FullView and Dr. Nalwa were engaged in a decades- 2 long fraud to conceal Nalwa 1996, why would they have made Nalwa 1996 publicly available on 3 FullView’s website since at least 2009, including during the pendency of IPR proceedings 4 regarding the ‘143 Patent? 5 Therefore, Polycom has not alleged facts sufficient to satisfy either of the two elements 6 required to claim for inequitable conduct; it has failed to state a plausible claim of inequitable 7 conduct. Exergen Corp., 575 F.3d at 1327 n.3. Thus, it would be futile for the Court to grant 8 Polycom leave to amend its answer to include a counterclaim for inequitable conduct. See Foman, 9 371 U.S. at 182. Given Polycom’s lack of diligence and undue delay in asserting this 10 counterclaim, the Court denies Polycom’s request for leave to amend its answer. 11 Furthermore, Polycom’s argument that FullView violated Patent Local Rules 3-2(a)-(b) by 12 failing to disclose Nalwa 1996 is similarly meritless. As already explained, Polycom has not 13 demonstrated that Nalwa 1996 discloses the patented inventions in the ‘143 Patent, and thus, it is 14 not a document that “evidence[s] disclosure to, or other manner of providing to a third party, or 15 sale of or offer to sell, or any public use of, the claimed invention prior to the date of application 16 for the patent in suit,” Patent L.R. 3-2(a), nor does it “evidenc[e] the conception, reduction to 17 practice, design, and development of each claimed invention,” Patent L.R. 3-2(b). Therefore, 18 FullView’s failure to disclose Nalwa 1996 did not violate the Rules and Polycom’s request to 19 compel FullView to produce additional documents pursuant to the Rule is denied. 20 D. Leave to Amend Invalidity Contentions to Include the UNC Device 21 Polycom also fails to demonstrate its diligence in locating the prior art of the UNC device, 22 nor to justify why it is seeking leave to amend now, more than a year after it filed its invalidity 23 contentions on August 31, 2020. Polycom does not explain why due diligence could not have led 24 it to discover the Majumder 1999 paper and reference to the UNC device therein earlier. No 25 explanation is given why Polycom was unable to locate this paper and its reference to the UNC 26 device. Nor does Polycom explain why it could not have met with Mr. Keller, the potential expert 27 from UNC, before serving its Invalidity Contentions. 1 31, 2020 when Polycom served its invalidity contentions with respect to the ‘143 Patent by 2 performing internet searches for prior art, engaging a prior art research firm, and working with a 3 subject matter expert.” Motion at 21. But this statement does not explain why Polycom did not 4 previously locate Majumder 1999—which appears to be a publicly-available paper—or why 5 Polycom did not previously become aware of the UNC device, which they allege was 6 demonstrated to thousands of members of the public in 1997. Id. at 11. Polycom makes an 7 unsubstantiated, conclusory assertion that “a device—even a device on public display is unlikely 8 to be uncovered by a prior art search firm who would be targeting publications and patents.” Id. at 9 21. But as Polycom stated itself, the UNC device was included and described in a publication, 10 Majumder 1999. Polycom failed to establish that there was any inherent “difficulty of locating the 11 prior art.” Golden Hour Data Sys., Inc, 2008 WL 2622794, at *2. Polycom fails to satisfy its 12 burden to establish diligence as required to be granted leave to amend its invalidity contentions. 13 O2 Micro, 467 F.3d at 1368. 14 Thus, the Court denies Polycom’s motion to amend its invalidity contentions to include the 15 UNC device. 16 V. CONCLUSION 17 The Court DENIES Polycom’s motion. Docket No. 164. 18 This order disposes of Docket No. 164. 19 20 IT IS SO ORDERED. 21 22 Dated: November 30, 2021 23 24 ______________________________________
