“We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012). The Technical Data Sheets may support a finding that the Xirallic® products they describe existed as of the dates on the documents, but they do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public.” slip op. at 20

“witnesses. See Elbit Systems of Am., LLC v. Thales Visionix, Inc., 881 F.3d 1354, 1358 (Fed. Cir. 2018) (citing Trs. of Columbia Univ. v. Illumina, Inc., 620 F. App’x 916, 922 (Fed. Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

“Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

“inter partes review. SAS Inst. v. Iancu, 584 U.S. 357, 366 (2018). Specifically, “[i]f a panel determines that a petition meets the standards for institution in relation to fewer than all the challenges presented, . . . the panel will evaluate all the challenges and determine whether, in the interests of efficient administration of the Office and integrity of the patent system, the entire petition should be denied.” See Consolidated Trial Practice Guide, 64 (Nov. 2019), available at https://www.uspto.gov/sites/default/files/ documents/tpgnov.pdf.

“In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Neither party argues, at least at this stage of the proceeding, that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’868 patent, the background technical field, the prior art, and Petitioner’s proposed and unopposed definition of the skilled artisan (Ex. 1012 ¶ 20), we apply the level of skill set forth above.” slip op. at 8

“Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Resp. 4). In determining at this stage of the proceeding that Petitioner has demonstrated a reasonable likelihood of establishing unpatentability of at least one challenged claim (namely dependent claim 11 in this case), we need not and do not construe expressly any claim terms. Nevertheless, we encourage the parties to submit proposed constructions for the limitation “determining a UE [i.e., User Equipment] environment information,” as recited in dependent claim 11. See Ex. 1001, 49:12–15, 1:40–42 (emphasis added). To the extent that a party proposes that this limitation should have its ordinary and customary meaning, the party should submit and explicitly identify such meaning. O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008) (“A determination that a claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”). For example, the parties should discuss (a) the meaning and scope of “determining” as used in the subject limitation; (b) the meaning and scope of “environment information” as used in the subject limitation; (c) any relationship or overlap between “environment information” and “link quality positioning information,” as recited in dependent claims 7 and 11 (see Ex. 1001, 48:62–65, 49:12–15); and (d) whether UE “environment information” includes location or orientation of the UE.” slip op. at 10

“Petitioner contends the skilled artisan would have had rational reasons to combine the teachings of Jarvinen and Fox to arrive at the invention of dependent claim 11 (which includes the features of independent claim 1 and dependent claim 7) and would have had a reasonable expectation of success in doing so. Pet. 37–41; see, e.g., id. at 38 (“[The skilled artisan] faced with the problem of estimating a UE’s future link quality at a location would have looked to Fox because Fox solves the problem of estimating future link quality with the exact same information available to Jarvinen.”); Ex. 1012 ¶ 70 (Dr. McClellan testifying that “[a]ll of the data upon which Fox relies is already disclosed and linked together in Jarvinen’s database, and it would have been obvious for [the skilled artisan] to combine Fox’s method of looking up previous link quality to estimate future link quality with Jarvinen’s teachings.”); ¶ 72 (Dr. McClellan testifying that “modifying Jarvinen to perform Fox’s link quality estimation would have constituted a simple substitution of a known element to yield predictable results.”). Patent Owner does not dispute such reasons or expectations at this stage of the proceeding. For the reasons and evidence set forth in pages 37–41 of the Petition, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox to arrive at the invention of claim 11, and to do so with a reasonable expectation of success. c) Summary At this stage of the proceeding and based on the record before us, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox with a reasonable expectation of success, and sufficiently supports Petitioner’s contention that dependent claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox.

“Petitioner also focuses on Hanafusa’s teaching that all known methods can be used to make a rough surface low-profile, and Dobashi’s teaching that RSm can be used as an indicator for judgment of the surface, to support its contention that a POSITA would have been motivated to apply Dobashi’s RSm to further achieve Hanafusa’s purpose, without explaining how and why that would be the case. In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness and is rough when RSm is small.” Id. at 3:1–3, 6:27–29.

“We agree that the lack of the word “means” recited in claims 1 and 9 creates a rebuttable presumption that § 112(6) does not apply. Williamson, 792 F.3d at 1348. “When a claim term lacks the word ‘means,’ the presumption can be overcome and § 112[(6)] will apply if the challenger demonstrates that the claim term fails to ‘recite[] sufficiently definite structure’ or else recites ‘function without reciting sufficient structure for performing that function.’” Id. at 1349 (citation omitted). “One way to demonstrate that a claim limitation fails to recite sufficiently definite structure is to show that, although not employing the word ‘means,’ the claim limitation uses a similar ‘nonce word that can operate as a substitute for ‘means’ in the context of § 112 [(f)].’” MTD Products, Inc. v. Iancu, 933 F.3d 1336, 1341 (Fed. Cir. 2019) (quoting Williamson, 792 F.3d at 1350). Patent Owner argues that “[a] general-purpose computer, i.e., a ‘controller,’ fails to recite sufficiently definite structure for performing the DSC’s claimed function.” PO Sur-Reply 3–4. Petitioner responds that the term “controller” has previously been found to not invoke § 112(6) because it is understood as having a definite meaning of structure. Pet. Reply 1–2 (citations omitted). Petitioner is correct that the Board and district courts have in some cases found a “controller” to recite sufficient structure. On this preliminary record, we are not persuaded that the evidence is sufficient to establish that the term “designation software controller” fails to recite sufficiently definite structure and overcome the presumption that § 112(6) does not apply. At this juncture, neither party has provided sufficient evidence as to how the claimed “designation software controller” would reasonably be understood by persons of ordinary skill in the art. See Williamson, 792 F.3d at 1349 (“The standard is whether the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure.”). In addition, regardless of whether “designation software controller” alone connotes structure, the claim language that follows the term “designation software controller” appears to provide structure. Specifically, the claim language appears to include a step-by-step procedure, namely 1) keep the information in memory in response to a termination of viewing; and 2) designate the succeeding part of the digital moving image contents when the viewing starts again. See Ergo Licensing, LLC v. CareFusion 303, Inc., 673 F.3d 1361, 1365 (Fed. Cir. 2012) (“Even described ‘in prose,’ an algorithm is still ‘a step-by-step procedure for accomplishing a given result.’”); Sage Prods., Inc. v. Devon Indus., Inc., 126 F.3d 1420, 1427–28 (Fed. Cir. 1997) (“where a claim recites a function, but then goes on to elaborate sufficient structure, material, or acts within the claim itself to perform entirely the recited function, the claim is not in means-plus-function format”). Accordingly, for purposes of this decision, we do not construe the claimed “designation software controller” as a means-plus-function limitation. No further construction of this term is necessary for purposes of this decision. During trial, the parties may provide further briefing on this issue.” slip op. at 10
