“29. In my opinion, the POSITA at the time of the alleged invention of the Asserted Patents would have had a (1) a Bachelor’s degree in a pertinent discipline, such as computer science, electric engineering, computer engineering, or a related field and (2) have 2–4 years of experience in working with computing devices and have an understanding of indexed search systems utilized by such computing devices. 30. I am aware that Petitioner has provided its own definition . . . . 31. I believe Petitioner’s definition is not meaningfully different from my definition of a POSITA. My opinions would not change regardless of which definition of POSITA is applied. Ex. 2001 ¶¶ 29–31. In our Decision on Institution, we adopted Mr. Haeberli’s formulation, finding it to be consistent with the evidence then of record, including the asserted prior art and the ’490 patent. Dec. 9. Following a review of the full record, we agree with Mr. Haeberli’s statement that Petitioner’s definition of one of ordinary skill in the art is “not meaningfully different” from Mr. Haeberli’s for the purposes of this proceeding. We continue to view Mr. Haeberli’s proposed definition as consistent with the ’490 patent and the asserted prior art, and we apply it in our analysis below. However, our analysis of the issues below would have been the same had we instead adopted Petitioner’s proposed definition.” slip op. at 9

“In our Decision on Institution, the only term that we found it necessary to construe was the term “string separator character” in claim 1. We preliminarily construed this term to mean “a single-character string separator.” Dec. 11, 30–31. We invited the parties to address the appropriateness of this construction over the course of the trial. Id. at 11, 31. In its briefing, Patent Owner agrees with the Board’s preliminary construction, arguing that it is “consistent with the intrinsic evidence.” PO Resp. 8 (citing Ex. 1001, claims 8 and 20). Patent Owner further argues that a person of ordinary skill would have understood a multi-character Boolean operator such as “AND” to be “a search syntax instruction rather than a string separator.” Id. at 9 (citing Ex. 1059, 162; Ex. 2001 ¶ 112). Petitioner’s Reply Brief does not address the issue of claim construction.

“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

“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

“c) Summary We may institute an inter partes review when “the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a). We have determined that, at this stage of the proceeding and on the present record, the information presented in the Petition does not show that Petitioner is reasonably likely to prevail with respect to its challenge to claim 1 based on the combination of Elliott and Jacob. Specifically, the Petition does not demonstrate that the proposed Elliott/Jacob combination would teach or suggest either limitation [1.e] or limitation [1.a] of independent claim 1. For the same reasons, the Elliott/Jacob combination does not teach or suggest the commensurate limitations in independent claims 6 and 11.

Each declarant, therefore, addresses issues that must be considered from the vantage point of a POSITA at the time of the invention, meaning a person with the level of ordinary skill defined in Section II.E.1 above. See Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc) (claim construction); KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007) (obviousness). If Mr. Daniels and Mr. Tulchin do not qualify as POSITAs, as Petitioner alleges, then their opinion testimony is inadmissible under Federal Rules of Evidence 702 (Testimony by Expert Witnesses). We find that there is insufficient evidence in the record to establish that Mr. Daniels qualifies as a POSITA in relation to the ’725 patent. Mr. Daniels has an undergraduate degree in engineering physics in addition to a law degree. Ex. 2121 ¶ 2. His declaration, however, does not establish that he also has “one year of experience related to marketing and distribution of multimedia material over a computer network, or the equivalent.” See Section II.E.1 above. Mr. Daniels characterizes his non-legal work experience as follows: The rest of my professional career has been spent working in my own companies in the research, development and prototyping/commercialization of a number of different technologies, principally including fishing rod technology, digital video file transport, storage and processing, LED-based light-emitting tapes, drone control systems, wearable medical related electronic devices and breath-based diagnostic devices. Ex. 2121 ¶ 3; see also Ex. 1023, 99 (Daniels Deposition) (describing work on “a suite of interactive television innovations,” including “the first working pause button”). None of the projects identified appears to relate to “marketing and distribution of multimedia material over a computer network.” Patent Owner argues that Mr. Daniels “was involved (at the time of the filing of the application which matured into the ’725 patent) in making inventions, that dealt with interactive television, video pause buttons and video file provision over the Internet.” Sur-Reply Br. 6. However, neither Mr. Daniels’ declaration nor his deposition testimony assert that he ever worked on “video file provision over the Internet,” let alone that he did so for one year or more. See Ex. 2121 ¶ 3; Ex. 1023, 98–100. We find that the evidence in the record is not sufficient for us to conclude that Mr. Daniels qualifies as one of ordinary skill in the art. We further find a lack of evidence establishing that Mr. Tulchin qualifies” slip op. at 9

- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaning
“When interpreting the meaning of a claim, “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). Patent Owner has, briefly, proposed six claim terms for construction: exhibition; exhibitor; broadcast exhibitor; distribution; marketing; and storing. PO Resp. 10. The Petition states that “[t]o resolve the grounds presented herein, Petitioner does not believe that any term requires explicit construction.” Pet. 12. We see no reason why “exhibition” and “exhibitor” should be understood as having a meaning as narrow as Patent Owner proposes. “Exhibition” and “exhibitor” encompass more than just a showing by “one in the exhibition business” because the specification of the ’725 patent identifies certain “exhibitors” that are not “in the exhibition business”: e.g., a high school, libraries, and other non-profit organizations. Ex. 1001, 12:38–41 (“schools, libraries, and other non-profit organizations”), Fig. 1 (“high school”). The plain and ordinary meaning of “exhibitors” is at least broad enough to encompass the types of exhibitors identified in the specification: movie theaters, television stations, satellite television operators, cable television operators, and non-profit organizations such as high schools. Ex. 1001, 4:20–22, Fig. 1. We further determine that some of these exhibitor types, including at least satellite and cable television operators, are “broadcast exhibitors.” Moreover, we find that the plain and ordinary meaning of the term “distribution” is not so narrow as to be limited to “the business of marketing films and providing copies to venues,” as Patent Owner proposes. See PO Resp. 10 (emphasis added). The claimed invention is a “method of marketing and distributing multimedia,” which is not limited to films. We agree with Petitioner that the term is at least broad enough to encompass distribution of any type of multimedia to any type of exhibitor contemplated in the specification. See Ex. 1001, 1:20–25 (multimedia types); Reply Br. 6. Similarly, the plain and ordinary meanings of “marketing” and “storing” are not limited to Patent Owner’s specific examples: interesting individuals in seeing a film and saving to non-volatile storage, respectively. See PO Resp. 10; Tr. at 57:3–7. The invention is directed to marketing and distributing multimedia, not just films, Ex. 1001, 16:21, and while the Specification refers to storing multimedia on “hard drives,” id. at 4:35–37, 4:44–52, there is nothing in the Specification, claims, or prosecution history that would limit storage only to hard drives or other non-volatile storage.

“Petitioner contends that a person of ordinary skill in the art would have been motivated to use Garfinkle’s video distribution system to implement Kosten’s distribution method to achieve the improvements described therein, such as: access to a large number of video products and advertising materials available at a centralized location (Ex-1007, 54; Ex-1005, 1:42–49, 1:54–2:12), improved advertising capabilities (Ex-1007, 54; Ex-1005, 1:42–49, 1:54–2:12), and improved distribution processes resulting in lower shipping and handling costs and labor intensity, improved security against piracy, wider and more flexible distribution capabilities, cost reductions for movie theaters, increased control over time and locations of exhibitions by studios and distributors, an ability to scale up or down distribution based on success in theaters, and an ability to track and monitor sales and marketing data (Ex-1007, 52, 54). Pet. 14 (citing Dystar Textilfarben v. C.H. Patrick, 464 F.3d 1356, 1368 (Fed. Cir. 2006) (A motivation to combine exists when the “improvement” results in a product or process that is “stronger, cheaper, cleaner, faster, lighter, smaller, more durable, or more efficient.”)). Petitioner further asserts that such a person would have had a reasonable expectation of success in achieving the objective of efficient content distribution through the proposed combination of Garfinkle and Kosten with no change in their respective functions because: (1) both are “from the same field and address the same well-known issues”; and (2) both references purport to achieve this objective in similar and predictable ways, “such as using the well-known teachings of digitizing content, correlating multimedia and associated advertising materials, and connecting multiple user sites to the central station through a public communications system.” Id. at 13, 16–17 (internal citations omitted) (citing Ex. 1005, 2:58–3:5, 3:32–49, 4:37–39; Ex. 1007, 54); Ex. 1002 ¶ 68. Patent Owner contends that there would have been no motivation to combine Kosten and Garfinkle because each represents a “complete solution[] to different file transport modes, Kosten involving simple file transmission to a theater and billboards, and Garfinkle involving file transmission to a [video-on-demand] user. Neither has a problem which is addressed by the other.” PO Resp. 33. Petitioner argues, however, and we agree, that “(1) a known technique can provide motivation to combine and (2) a known technique does not need to improve upon the primary reference—it just must be a ‘suitable option.’” Reply Br. 21 (citing Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023)). Thus, it does not matter that Kosten and Garfinkle each represent a complete and functional solution to digitally transporting media files. If the references in the combination address a known problem, such as issues with multimedia distribution, see Pet. 13–14, and the proposed combination is a suitable solution, then there would have been a motivation to combine the two references. Moreover, Petitioner persuasively argues that by combining Kosten and Garfinkle, one of ordinary skill in the art would have been able to achieve benefits such as lower shipping and handling costs, improved security against piracy, wider and more flexible distribution capabilities, an ability to more easily scale distribution up or down as needed, among other benefits. Pet. 14. We find that these benefits would have provided a sufficient motivation to combine Garfinkle’s technical implementation of a distribution process for large multimedia files with Kosten’s proposed business application, “beaming” films directly to theaters via satellite. Patent Owner’s arguments to the contrary are without merit.” slip op. at 21

Usui’s description of a plurality of metal layers (layers 13–18) and a capping layer formed over the plurality of metal layers (layer 19), along with its description of the structure’s usefulness for forming electrical connections in an integrated circuit structure, is sufficient, on this record, to establish that Usui discloses “an electrode stack including a plurality of metal layers and a capping layer formed over said plurality of metal layers” as recited in claim 1. Usui’s teaching that the capping layer is a refractory metal nitride (titanium nitride) that has a thickness (150–800 Å) greater than the bottommost layer of the plurality of metal layers (layer 13, 90–110 Å), sufficiently establishes, on this record, that Usui discloses the “said capping layer consisting only of a refractory metal nitride, said refractory metal nitride forming a top of said electrical contact and having a thickness greater than that of a bottommost layer of said plurality of metal layers” limitation of claim 1.” slip op. at 11

“a bachelor’s degree in computer science, electrical engineering, computer engineering, or a closely related field, and one to three devices that used common wireless communications protocols such as Bluetooth and 802.11/Wi-Fi. More education, e.g., a Master’s or Ph.D., would compensate for less work experience and vice versa. 305 Pet. 13–14; accord 306 Pet. 14. Patent Owner “has adopted Microsoft’s definition for this proceeding.” 305 PO Resp. 6; accord 306 PO Resp. 6. Neither party argues that a particular level of ordinary skill in the art makes a difference in the outcome of the issues presented in these proceedings. Accordingly, we adopt Petitioner’s level of ordinary skill in the art, which we find to be consistent with the record evidence, particularly because it specifies having one to three years of experience working with wireless devices that use Bluetooth and 802.11.” slip op. at 11

“We conclude that for the purposes of this Decision, we need not determine whether the claim term “detecting” encompasses “soliciting” detectable responses from other devices, as Patent Owner proposes, Sur- Reply 3, or whether Petitioner is correct that “solicitation and detection are distinct acts, and thus using Bluetooth for solicitation is not using Bluetooth for detection.” Reply 5. As discussed in Section IV above, “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” Nidec Motor Corp., 868 F.3d at 1017 (quoting Vivid Techs., 200 F.3d at 803). Here, it is not necessary to construe the term “detecting” to determine that no presumption of nexus exists because, for the reasons discussed below, we find that AirDrop is not coextensive with the challenged claims under either party’s interpretation of the term.” slip op. at 38

“device uses significantly less power than if a high speed seek was used.” Ex. 1005 ¶ 43. However, once a connection between two devices is established, Petitioner persuasively argues that “[a] POSITA would have been motivated to implement devices based on these teachings to switch from Bluetooth to Wi-Fi to transfer content, as taught by McKillop, because Ex. 1003 ¶ 70. Petitioner contends that a person of ordinary skill in the art at the time of the invention “would have reasonably expected to succeed in implementing these features because they would have required only minor software code that was well within the skill of a POSITA, as evidenced by these features’ ubiquity in the prior art.” Pet. 19–20; see Ex. 1003 ¶¶ 38–45 (ubiquity in the prior art), 72 (only “minor software code” required). Petitioner also persuasively argues that one of ordinary skill “would have been further motivated to implement the Ahya+McKillop wireless devices to prompt users to accept or deny incoming file transfers, as described by numerous background references[,]” and would have had a reasonable expectation of success in doing so. Pet. 22; see Ex. 1003 ¶¶ 46– 51 (background references), 78–81 (motivation), 83 (only “minor software code” required to implement combination). We find that on the full record Petitioner has sufficiently established that a person of ordinary skill in the art at the time of the invention would have been motivated to combine Ahya and McKillop.

“Here, the evidence demonstrates that AirDrop includes significant unclaimed features that are likely to have been major contributors to any commercial success or industry praise that Apple’s AirDrop-equipped devices have enjoyed. This is true even if the analysis is limited to the AirDrop feature itself, rather than to the entire Apple device. See Sur- Reply 10–11 (“Patent Owner is not claiming the commercial success of the iPhone to show a presumptive nexus. “). Petitioner identifies three major features of AirDrop that are not part of the claimed invention: (1) device visibility controls implemented using iCloud services-based authentication; (2) security, including encryption; and (3) tight integration within the Apple ecosystem.

“Because the inputs are used by the processor to create the database, the inputs must be received by the processor prior to creation of the database. Creation of a database is a way of provisioning a database, as explained in the specification of the ‘818 patent. Ex. 1001, 3:41–43 (“Database provisioning services involve creating and/or associating databases with the database system for management and use.”). The SLA then protects the database “after” it is provisioned (per limitation [1D]) and a snapshot may be captured “after” the database is provisioned (per limitation [1E]). For the foregoing reasons, Petitioner has shown a reasonable likelihood that it would prevail in establishing that claim 1 would have been obvious over Sivasubramanian and Zha. 4. Dependent Claims 2–7, 22, 23, 28–30 Claims 2–7, 22, 23, and 28–30 each depend, directly or indirectly, from claim 1. Ex. 1001, 40:31–57, 42:17–22, 42:35–53. Patent Owner does not present arguments for these claims separate from those it submits for claim 1, which we have rejected above in the context of claim 1.

“With respect to limitation [1E], Petitioner asserts that it would have been obvious for one of ordinary skill in the art to incorporate into Sivasubramanian Zha’s feature of user input of the frequency for retrieving snapshots and user input of the “times during the day” for retrieving snapshots. Pet. 52–54. Patent Owner does not dispute the assertion. We have reviewed the evidence cited by Petitioner, and agree on this record that Sivasubramanian and Zha reasonably would have suggested limitation [1E]. With respect to limitation [1F], Petitioner notes that Sivasubramanian already discloses a user interface to receive the first, second, and third inputs, and asserts that if there are fourth and fifth inputs based on an analysis of limitation [1D], then one of ordinary skill would have used the same interface to receive the fourth and fifth inputs. Pet. 54–55. Patent Owner does not dispute the assertion. We have reviewed the evidence cited by Petitioner, and agree on this record that Sivasubramanian and Zha reasonably would have suggested limitation [1F]. With respect to limitation [1H], Petitioner asserts that a person of ordinary skill in the art (POSA) “would have understood that the purpose of accepting these inputs [first through fifth] is to use them to ‘create’ a database based on these inputs and based on the amount of storage determined from the user input.” Pet. 57 (emphasis omitted).

“Regarding the alleged anticipation by Okaya, Petitioner has not adequately shown that Okaya discloses that the audio and video outputs of carousel 10 connect to a communication network without the intervening use of a computer or video conferencing system to which the carousel is connected. Okaya specifically describes that “the multimedia carousel 10 includes several input and output terminals for integrating with a multimedia computer or video conferencing system.” Ex. 1006, 3:1–4.

“For reasons discussed below, we find Petitioner’s reasoning to be insufficient for one of ordinary skill in the art to add two cameras to Nagasawa’s case body 1, one on each side of case body 1. Petitioner does not adequately address the issue of sufficient spacing on Nagasawa’s case body 1, which includes two back-to-back mounted displays 4 and 8 (Figure 1A), to include two additional cameras, one facing inward and the other facing outward, particularly as one side of case body 1 is used for gaming (Fig. 1B, Ex. 1007, 3:53–65). In Nagasawa’s fifth embodiment, which includes a camera for video conferencing, the camera is placed in the hinge connecting case bodies 1 and 2, and not within case body 1. That is an indication that there is not enough room in Nagasawa’s case body 1 to incorporate a camera, much less two cameras as Petitioner has proposed to meet limitations [18c] and [18d]. Nagasawa’s Figure 12B is reproduced below: Figure 12B is a front view of a fifth embodiment of Nagasawa’s foldable phone in the unfolded position. Ex. 1007, 3:24–26. Nagasawa describes: “Video conference display may be provided where the photo sticker 51 is to be affixed in order to provide folding portable apparatus equipped with a small-sized TV camera 53 at the hinge.” Id. at 7:36–39. Nagasawa’s design already dictates where a camera would be mounted, and omits discussion of any other locations of that camera, much less a placement of it on the phone case body. Id.” slip op. at 23

“Additionally, Dr. Theogarajan testifies: “A person using [Nagasawa’s] pocket game would cover any camera placed on the outer surface of the first case body. Any camera placed in such a position would be abused with dirt and oil from a game player’s hand.” Ex. 2001 ¶ 145. We credit the testimony. It further undermines Petitioner’s proposed addition of two cameras to Nagasawa’s case body 1. Also, Nagasawa’s fifth embodiment already includes a video conferencing camera facing the user, mounted in the hinge connecting case bodies 1 and 2. In light of that teaching, there is little reason to add a camera to the inward facing side of Nagasawa’s case body 1.” slip op. at 24
