      “In our Institution Decision, we construed the claim term “string separator character” to mean “a single-character string separator,” and invited the parties to raise any issues they had with this construction in future briefing. D.I. 10. Patent Owner subsequently indicated that it agreed with this construction. See PO Resp. 8. Petitioner did not raise any objections to this construction (see generally Pet. Reply). Accordingly, and in the absence of any dispute, we construe “string separator character” to mean “a single-character string separator.” Neither Petitioner nor Patent Owner ask us to adopt explicit constructions of any other claim terms. See Pet. 14, PO Resp. 8–9; Pet. Reply 1–23; PO Sur-reply 2–7. We also find that the issues in dispute can be resolved without construing any other claim terms.

      “search functionalities disclosed in the Lotus Notes References and Raskin are materially different in such a way as to render combining them anything but simple and straightforward.” See PO Resp. 26–27. Indeed, Petitioner has given little or no explanation of how one of ordinary skill in the art allegedly would have taken the “idea of incremental search” and applied it to Lotus Notes. See, e.g., Ex. 2021, 116:20–117:17 (Petitioner’s declarant, Dr. Terveen, testifying that “Raskin is not explicitly talking about searching across a set of documents, but the teaching that I relied on in general from Raskin is the idea of incremental searching,” and “I did not have to talk about implementation level details or incorporating a particular implementation. That wasn’t necessary for my opinion.”). Raskin simply does not teach a mode of incremental searching that applies to the query-style, document-finding searching of the type Petitioner cites from Lotus Notes. See generally Ex. 1021; see also Ex. 2020 ¶¶ 34–35 (Mr. Haeberli contrasting the Lotus Notes searches cited by Petitioner with Raskin’s searches). Raskin even states that it is “difficult or impossible to implement incremental searches” using interface-building tools.

    • Expert testimonyPetitioner expert discountedPatent owner expert creditedDecided for patent owner

      “Having reviewed the evidence of record, we find Mr. Haeberli’s testimony to be more persuasive and better supported by the evidence. According to Dr. Terveen, “[r]obust programming languages such as C and C++, together with well-developed operating system and UI frameworks, . . . allowed an ordinary programmer to build a UI that supported incremental searching, as evidenced by the numerous prior art systems that implemented such functionality, including Entourage, Eudora, Emacs, Canon Cat, SwyftWare, and others. Ex. 1100 ¶ 43 (citing Ex. 1004, 8–9, 161; Ex. 1021, 125, 127, 129; Ex. 1039, 102–103; Ex. 1043, 385–389). The relevant question, though, is not whether it would have been possible to build a user interface that supported incremental search, but whether it would have been “simple and straightforward” to execute an incremental search of multiple partial search strings on large, indexed multi-file databases such as those described in the Lotus Notes references, as Dr. Terveen alleges. None of the prior art discussed in the “State of the Art” section of Dr. Terveen’s initial declaration, taken individually or together, discloses incrementally searching a plurality of files using two partial search strings. See Ex. 1003 ¶¶ 32–33, 37, 40; Ex. 2001 ¶ 100. Thus, creating a user interface might be “simple,” but the evidence suggests that the back-end execution of an incremental search is not. See, e.g., Ex. 1021, 126 (Raskin, concluding that “almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches”).” slip op. at 23

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable

      “different approach from that taken in Lotus Notes. The difference between Raskin’s sequential scanning method and the index-based system described in Wilcox is that sequential scanning by definition can only scan one document at a time as each document is loaded into a “buffer.” See, e.g., Ex. 2020 ¶ 35. Lotus Notes, however, only needs to load the index into memory for a user to be able to locate the single index entry identifying all instances of an indexed term across all indexed files. In fact, Raskin acknowledges that indexing may be necessary to maintain an acceptable response time. Ex. 1021, 132 n.10; see also id. at 129 (indexing speeds search times). Mr. Haeberli’s third and final reason for concluding that one of ordinary skill would not have been motivated to combine Raskin’s incremental search with Lotus Notes is that at the time using incremental searches would have presented “extreme technical difficulties.” Ex. 2001 ¶ 101. Here again we find Mr. Haeberli’s explanation more persuasive than Dr. Terveen’s opinion that combining the teachings from Raskin with Lotus Notes’ teachings “would have required only simple and straightforward software modifications.” Ex. 1003 ¶ 80. According to Mr. Haeberli, “there are serious technical challenges with implementing the complex search strategies of the challenged claims in the systems on which Dr. Terveen relies.” Id. ¶ 96. As Patent Owner argues: searching across a set of files to find specific files requires the system to identify which files are in the set, access those files (which are often not loaded in active memory), search their contents, determine which files contain matches to search criteria, and then present results to the user; all tasks that do not exist in the same way (or at all) for a search confined to text in a single open file already loaded into memory. Sur-Reply 9; see Ex. 2020 ¶¶ 15, 35–36. There would have been other challenges as well. For example, “[t]he type of sequential scanning typically employed to search a single open document is very time and resource intensive if employed to search a large set of documents.” Ex. 2020 ¶ 15. Also, “[i]mplementing incremental search in the Lotus Notes indexed system would necessarily require a larger index, which would slow down, rather than increase the search speed.” PO Resp. 23; see Ex. 2020 ¶ 33. Finally, Raskin itself concludes that “even if incremental searching is advantageous, ‘almost all interface-building tools make it easy to implement delimited searches and difficult or impossible to implement incremental searches.’” Ex. 2001 ¶ 96 (emphasis added by Mr. Haeberli) (quoting Ex. 1021, 126). In short, Mr. Haeberli presents three significant reasons why there would have been no motivation or expectation of success in combining the teachings of Wilcox with those of Raskin. Dr. Terveen’s opinion to the contrary, on the other hand, is not supported by evidence. Dr. Terveen testifies that “[a] POSITA would have been motivated to perform Lotus Notes’ multi-string search incrementally for the reasons stated by Raskin: speed, effectiveness, and ease of use.” Ex. 1003 ¶ 78 (citing Ex. 1021 ¶¶ 125–127). The evidence, however, not only fails to support Dr. Terveen’s testimony, but also demonstrates that one attempting to make the proposed combination would not have reasonably expected the proposed combination to result in greater speed or effectiveness.” slip op. at 27

      “We agree with Patent Owner that a problem with Petitioner’s combination is that it proposes to take the idea of incremental searching from Raskin and divorce it from Raskin’s teaching of incremental searching. See PO Resp. 20 (arguing, “a [person of ordinary skill in the art] must consider all the teachings of a reference, and not pick out general ‘concepts’ disclosed in the art without considering the context in which they are used”); see also id. at 17–28 (setting out the whole argument); Ex. 2020 ¶¶ 39–62 (Patent Owner’s declarant explaining why Petitioner’s approach is “technically problematic”). Raskin’s incremental search is tied to finding and moving to character strings within a document. Ex. 1021, 125. For example, if a user were to type a string that was found in the text, “the instance [of that string] is selected and the cursor placed immediately after the end of the selection.” Id. The cursor can move about the text as characters of the search string are added or deleted. Id. at 125–126. Thus, Raskin discloses in-text search, even when searching across documents. Id. at 132 (“After the local document has been completely searched the search then proceeds through the following documents until the end of the folder is reached, when the search continues from the beginning of the first document in the folder until the current, already searched document is reached. After cycling through the folder, the next larger domain is treated similarly, and so forth.”). Raskin even distinguishes its text-finding search from Lotus Notes’ document-finding search, stating that “[i]t is usually easy to tell in what domain you are searching, because you see the results in context; what you see is not just a list of file names, as with many present search systems.” Id. (emphasis added); see also PO Sur-reply 16 (citing the same page and arguing that “Raskin recommends doing the opposite of what is claimed”). This context gives credence to Patent Owner’s argument that “the search functionalities disclosed in the Lotus Notes References and Raskin are materially different in such a way as to render combining them anything but simple and straightforward.” PO Resp. 26–27. Indeed, Petitioner has given little-to-no explanation of how one takes the “idea of incremental search” and applies it to Lotus Notes. Ex. 2021, 116:20–117:17 (Petitioner’s declarant testifying that “Raskin is not explicitly talking about searching across a set of documents [at once], but the teaching that I relied on in general from Raskin is the idea of incremental searching,” and “I did not have to talk about implementation level details or incorporating a particular implementation. That wasn’t necessary for my opinion.”). Raskin does not teach a mode of incremental searching that applies to the query-style, document-finding searching in Lotus Notes. See generally Ex. 1021; see also Ex. 2020 ¶¶ 34–35 (Patent Owner’s declarant contrasting Lotus Notes and Raskin).

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightMotivation not foundNot shown unpatentable

      “Entourage and what True is doing and how it is doing it, Petitioner asserts that it would have been obvious to use True’s two search strings “to provide more targeted searching, as was common sense and well known in the art.” Pet. 60 (citing Pet. 8–9; Ex. 1057, 27); see also id. at 56, 66 (similar). But we are not persuaded by a preponderance of the evidence that True provides more targeted searching or better search results when finding documents. True itself appears silent on the issue. Petitioner cites Exhibit 1057, but all that stands for is the general premise that doing a Boolean AND search in a Web search engine reduces the number of search results. Ex. 1057, 27. Petitioner does not allege that True uses a Boolean AND search of the kind discussed in Exhibit 1057. Thus, the statement in Exhibit 1057 regarding reducing the number of search results is tied to a manner of performing Boolean searches, something Petitioner does not use to modify Entourage. In other words, Exhibit 1057 is of little relevance to the Entourage-True combination, and does not serve as a factual underpinning in support of Petitioner’s reasoning. Petitioner also cites to several other references that discuss Boolean-style searches, but these generic background disclosures do not explain why a person of ordinary skill in the art would have considered it obvious to use one or more features of the probabilistic-based interest level search from True in a document-finding application like Entourage. See Pet. 8–9 (string citing over a dozen references with no pinpoint citations). Accordingly, there appears to be little reason, absent hindsight, to incorporate some aspect of a text-as-proxy-for-sounds system like True into Entourage’s filter or Find feature to provide more targeted searching. Accord Ex. 2020 ¶ 120 (“Patent Owner’s declarant stating that “a [person of ordinary skill in the art] working on the problem of searching large document collections would not look to [True,] a system designed for navigating imprecise transcriptions of single audio files, as the technical approaches and constraints are entirely different”). Patent Owner argues, and we agree, that another problem with Petitioner’s combination is that True does not appear to actually provide more targeted or better searching. PO Resp. 59–60 (“True’s search capabilities are inherently imprecise”) (citing Ex. 1009, 1:18–27; Ex. 2001 ¶ 137); see also Ex. 1009, 4:31–37 (explaining that True uses a speech recognition system that calculates confidence levels based on a “% likelihood that [a word] corresponds to the portion of the digitized audio [at a given time]”); Ex. 2020 ¶ 114 (Patent Owner’s declarant stating that “the purpose of True is not to definitively locate where a search string actually appears”). Petitioner does not explain what about True would make some aspect of Entourage’s filter or Find features more targeted. Even if it was known to use Boolean AND searches, for example, Petitioner is not citing True to modify Entourage to have a Boolean search. True uses an “interest level” search instead, which is more inclusive than a Boolean AND search (it adds together hits for “queen” OR “mother,” and may return hits containing neither). Ex. 1009, 5:29–50, Fig. 2 (showing results list 22 having several results which do not indicate any of the searched-for words); see Ex. 2020 ¶ 116 (Patent Owner’s declarant analyzing True’s interest level search would also include “text [that] does not show the query word”). Petitioner does not appear to be proposing to incorporate an interest level search or a Boolean-style search into the filter or Find features, and we are not persuaded that True in fact provides more targeted searching. Even if the quality of the transcripts in True happened to be perfect (see Pet. Reply 10, arguing that “True describes searching a text file that has 100% accuracy”), the fact remains that True attempts to find text in particular time windows using an interest level search based on the probability that a word or words were spoken in a given time window, which is completely different from what Entourage is doing with its search (see Ex. 2020 ¶¶ 114–116, 121). In its Reply, Petitioner states that True teaches “an incremental search for multiple search strings entered in a search field.” Pet. Reply. 10. This is a broad generalization of what True does, made with the benefit of hindsight, but as we have just explained, True’s interest level search is different from the kinds of searches done in Entourage or even the Boolean-style web searches performed in the background references. See, e.g., Ex. 1057, 27. This means it is not a matter of taking one known teaching and simply applying it to another system. True is doing something different, and it’s not clear how True’s search would actually provide “precise, targeted search results” (Pet. Reply 3) given that True appears to suggest a less-targeted search than claimed (see, e.g., Ex. 1001, 29:62–63, claiming “identifying one or more documents included in both the first one or more documents and the second one or more documents”). See also Ex. 2001 ¶¶ 135 (Patent Owner’s declarant stating that “Entourage and True are directed to completely different purposes”), 136–138 (further analysis); Ex. 2020 ¶ 114 (stating that “the purpose of True is not to definitively locate where a search string actually appears”), ¶ 116 (stating that True returns text that does not even have the search word). True does not teach, suggest, or support Petitioner’s general premise that there is a benefit for an incremental search for multiple search strings entered in a search field or that such searches would provide precise, targeted search results. The problem with Petitioner’s analysis becomes more apparent when the Petition turns to the “string separator character” of claim 1. Notably, it is the claimed string separator character that converts a field with a single search string into a field with two search strings. See, e.g., Ex. 1098, 37:12– 41–4 (deposition of Patent Owner’s declarant) (discussing that a string separator character is what instructs the computer to break up one string of characters into separate strings of characters). Thus, one cannot discuss the string separator character apart from the limitations requiring first and second search strings in a single search field. Nevertheless, Petitioner treats the “string separator character” in isolation. See Pet. 61–62. Petitioner’s reason for modifying one or both of Entourage’s filter and/or Find feature(s) to have a string separator character is because “it was common to [use string separator characters].” Id. at 61. However, even if something was known, it does not mean it is obvious to incorporate it into one or both of these features in Entourage. KSR, 550 U.S. at 418 (“a patent composed of several elements is not proved obvious merely by demonstrating that each of its elements was, independently, known in the prior art”). Adding a string separator character to divide a single string into two separately searched strings changes how the software would function. See Ex. 1098, 39:22–40:8 (Patent Owner’s declarant testifying that software has to look for a string separator character in order to know multiple search strings were entered in the field). The space character in “Orson Welles,” used in the Advanced Find example in Barber, for example, is not a string separator character because one looking to exclude hits with “Orson Welles” is searching for the string “Orson Welles”—the space is another character in the name string whose inclusion serves a specific semantic purpose (delineating between a first and last name). See Ex. 2001 ¶ 151 (“there is no evidence that when a user types ‘Orson Welles’ into this Find command text box that a search is performed on ‘Orson’ and ‘Welles’ separately as opposed to searching on the full text string ‘Orson Welles.’”); Ex. 1006, 387 (discussing how exclude the specific person “Orson Welles” from the search, not to find someone having the first name “Orson” or the last name “Welles”); see also Ex. 1003 ¶ 144 (Petitioner’s declarant implicitly acknowledging that the space in “Orson Welles” is not a string separator character). Thus, the space character in “Orson Welles” does not signal to the computer to break the string up into two parts at the space and perform” slip op. at 42

But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra. Id. ¶ 19; see also In re Etter, 756 F.2d 852, 859 (Fed.

Petitioner’s grounds for both independent claims 1 and 16 rely on Zhou for teaching a low-light high-pass parameter or a stickiness parameter. Pet. 23–28, 64.

Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

      “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

      “Given the teachings of the specification, we agree with Patent Owner that a low-light high-pass parameter is a parameter of a smoothing function that favors high frequencies (high pass) when exposure times are long (low light). See Tr. 42:10–18 (Patent Owner’s counsel stating that “high-pass” means “there’s a bias or preference for high frequencies”); Ex. 2020, 93:23– 94:15 (Petitioner’s declarant, Dr. Katsaggelos, agreeing that a high-pass system attenuates the low frequency of a signal). Although we acknowledge Petitioner’s position that the specification provides other ways or considerations in implementing a smoothing function, based on our above analysis of the specification, we find that the specification describes the lowlight high-pass parameter as a specific component of a smoothing function. See, e.g., Ex. 1001, 21:17–25 (setting out several parameters besides the low-light high-pass parameter used in trajectory smoothing).” slip op. at 10

      “position and a real device position. Id. at 18:27–40. In other words, the blur is addressed by analyzing the image to identify motion and then shifting the image. Shi, however, does not disclose how its parameter is based on low light (or the long exposure times indicative of low light). In its Petition, Petitioner asserts that a person of ordinary skill in the art would understand that “blurs can be caused by low light conditions.” Pet. 28 (citing Ex. 1003 ¶ 111). Although this is true, that does not mean that Shi’s blurs are identified by a parameter that considers low light. As we just described, Shi identifies the blur by quantifying the amount of motion of the points in an image, not by identifying low light. This is simply a different way to determine the presence of motion blur. In Shi, blur is measured, whereas in the ’840 patent, it is inferred based on low-light conditions (e.g., by observing the exposure time). See, e.g., Ex. 1007, 18:7– 26; Ex. 1001, 19:12–26. In its Reply, Petitioner does not point to any further disclosures. Accordingly, we find that Shi does not disclose the “low-light” aspect of the claimed low-light high-pass parameter. This is sufficient to determine that Petitioner’s ground does not meet all claim limitations. Similarly, we find that Shi does not disclose the “high-pass” aspect of the parameter. Shi’s blur compensation uses a spherical interpolation to modify the image. Ex. 1007, 18:27–40. The low-light high-pass parameter, as we have construed the term, allows more high frequencies. To allow more high frequencies, this necessarily means either allowing fewer low frequencies, or allowing more high frequences as opposed to some counterfactual situation in which fewer high frequencies were going to be allowed. See Ex. 2020, 94:23–95:15; Ex. 2022. We are directed to no persuasive evidence from Petitioner that Shi’s spherical interpolation favors high frequencies over low frequencies. Accord Ex. 2018 ¶ 107 (Patent Owner’s expert stating that Shi’s spherical interpolation “reintroduce[es] both high- and low-frequency motion”). Even if Shi allows the viewing window to track the camera position “consistent with the natural blur in the image” (Ex. 1007, 17:63–67), we are not provided with sufficient evidence to conclude by a preponderance of the evidence that providing a similar visual goal as a high-pass parameter (Ex. 1001, 22:16–18, “the output motion may include high frequencies that mask motion blur”) is the same as having a high-pass parameter. Again, merely preserving high frequencies is not the same as having a “high-pass parameter” because, as construed, a “high-pass parameter” also involves some degree of attenuation of low frequencies or relative increase of high frequencies. Accordingly, we find that Shi does not disclose the “high-pass” aspect of the claimed low-light high-pass parameter.” slip op. at 18

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.

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.

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

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.

Certainly, each shelf label in the real world, as well as in the drawing of Figure 4, has a horizontal position. However, that does not mean that Fujiwara’s database stores information indicating the horizontal position of the shelf label as required by the claim. The claim is not calling for the shelf label to have a location; it is calling for location information to be accessible by the server so that the server can determine the location of the mobile terminal. Ex. 1001, 8:19–24 (claiming a “method being performed by a central server configured to access a planogram associating . . . identifiers . . . with . . . locations . . . defined by a vertical and horizontal position”), 8:41–46 (claiming a method step of “determining a location of the mobile terminal . . . based on . . . the planogram).

To the extent we accept that Fujiwara teaches a unique identifier (shelf label ID) and a vertical position (e.g., shelf number 21-1), we find Fujiwara to be missing a horizontal position as required by the claim because neither the shelf number nor the shelf label ID provides an indication of where along the shelf the shelf label is located.” slip op. at 14

Rather, the Petition merely asserts that a POSITA would have understood that the gate recess of Figure 1A is optional without providing any persuasive reason why a POSITA would have removed the gate recess but retained the sloped sidewalls of Figure 1A. Pet. 25, 40, 45. For example, Petitioner asserts that Saxler’s gate contact may be “recessed or non-recessed” and that when the gate recess shown in Figure 1A is not utilized, Saxler would have the structure of Saxler Modified Figure 1A. Pet. 25 (citing Ex. 1003 ¶ 81; Ex. 1007 ¶ 52, 66); see also Pet. 40, 45 (citing Ex. 1007 ¶ 52). Neither of these paragraphs provide sufficient motivation to a POSITA to remove the gate recess from Saxler Figure 1A. Saxler paragraph 52 states: Exemplary devices according to some embodiments of the present invention are schematically illustrated in FIGS. 1A through 6. Thus, while embodiments of the present invention are described herein with reference to a recessed gate structure or a non-recessed gate structure, other embodiments of the present invention may include or not include a gate recess. Accordingly, embodiments of the present invention should not be construed as limited to the particular exemplary embodiments described herein but may include any suitable structure having a cap layer and/or passivation layer as described herein. Ex. 1007 ¶ 52. Petitioner’s expert, Dr. Shealy states that he understands paragraph 52 to mean that it is “fair game to pull the recess out of any of those figures [Figures 1A through 6].” Ex. 2004, 39:12–21. Dr. Shealy, however, also clarifies that “[a]s I said before, I think you could take all the embodiments and bring in which ones you want, depending on what you’re trying to accomplish.” Ex. 2004, 40:24–41:1. During the hearing, Petitioner admitted that Dr. Shealy’s “statement to modify the reference depending on what you're trying to accomplish” means that “a POSITA may modify with reason to do so. A POSITA would have removed Saxler’s recess to obtain the benefits of enhancement-mode.” Tr. 19:19–25. Again, the Petition does not provide a reason why a POSITA would have removed Saxler’s gate recess.” slip op. at 28

    • Expert testimonyPatent owner expert creditedDecided for patent owner

      “We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

      “understanding of a person of ordinary skill in the art (sometimes abbreviated herein as “POSITA”). Graham, , 383 U.S. at 17–18. Petitioner argued that a person of ordinary skill in the art would have had a “at least a four-year degree in electrical engineering, chemical engineering, physics, or material science or a closely related field and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies. Additional education could substitute for professional experience and vice versa.” Pet. 11 (citing Ex 1003 ¶ 69). Patent Owner did not dispute this proposed definition prior to institution. See generally Prelim. Resp. In our Decision on Institution, we adopted Petitioner’s proposal. After institution, Patent Owner asserted a slightly different definition of a POSITA, namely someone who “would have possessed at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” Resp. 17. Relevant graduate education could substitute for the professional work experience. Id. Upon review of the full record, we see no reason to modify, and we thus maintain, the definition of a POSITA applied in our Decision on Institution. We also determine that our decision would be the same under either of the parties’ proposed definitions.” slip op. at 14

      “During the proceeding, the parties also dispute the proper construction of “etching away the doped GaN layer, except a portion of the doped GaN layer beneath the gate contact” as recited in step [1e4] and provided briefing on this issue. Papers 35, 36, 37, 38. Because, as explained below, our determination rests upon Petitioner’s failure to show a sufficient reason to modify the asserted art, which is not dependent upon any particular claim construction, we need not, and do not, address these claim construction issues. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)) (holding that only claim terms in controversy need to be construed, and only to the extent necessary to resolve the controversy).” slip op. at 13
