“McCulloh’s qualifications are grounded upon Patent Owner’s “proposed level of skill” (which we rejected) that is “higher than Petitioner’s proposed level” (which we adopted for this proceeding) and focus on their level of skill in the late 1990s timeframe (time of the invention), but there is no time requirement on when an expert acquired the requisite level of skill in the art. Osseo Imaging, LLC v. Planmeca USA Inc., 116 F. 4th 1335, 1340–1341 (declining to add a timing requirement to the minimum qualifications necessary to offer expert testimony from the perspective of a person of ordinary skill in the art). “An expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art. Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention. In practice, the fact that the expert was not a person of ordinary skill at the time of the invention may well be used during cross examination to undermine the credibility of the expert.” Id. Under Petitioner’s proposed level of skill (which we adopted), Dr. McCulloh is indeed qualified to testify in this proceeding because he has a Ph.D. in Computer Science from Carnegie Mellon University and extensive experience, including “hands-on deployment and academic research in distributed systems operating under real-world constraints” (Ex. 2009, Ex. 2010). See Ex. 2010 (CV) (BSIE, MS Comp. Sci, PhD Comp. Sci, Lieutenant 1994-1999, 10th Mountain Division (“led the army’s first tactical deployment of a distributed computing system”)); Ex. 2009 ¶¶ 6–10.

Ex. 2009, ¶¶ 3, 5–34; Ex. 2010. Dr. McCulloh does not provide testimony to refute Petitioner’s obviousness analysis based on Yurt and Logan. See Ex. 2009. Mr. Johnson is only offered to refute Petitioner’s obviousness analysis based on Yurt and Logan. Ex. 2007 ¶¶ 3, 18, 29. Under Petitioner’s proposed level of skill (which we adopted), Mr. Johnson, who is a co-inventor of the ’128 patent, is qualified to testify in this proceeding, especially, when his declaration states that (1) he is a POSITA “with more than 30 years of experience building technology-driven media and contentdistribution systems” and (2) he “was actively involved in the development and deployment of digital music and video distribution technologies” since the mid-1990’s, including “real-time and near-real-time electronic delivery of media content.” Ex. 2007 ¶¶ 9–10, 14, 16.

“Plain Meaning of “Substantially Real Time” Instead, the plain meaning of “substantially real time” is readily apparent and understood by a person of skill (POSITA) in the art in the context of data distribution or transmission of the ’128 patent as referring to an acceptable time delay (i.e., “a fraction of real time”) between distribution center 18 and user device 12, via network 14, shown in Figures 1–2 of the ’128 patent and, as such, is consistent with the ‘128 patent’s specification and Dr. Lippman’s Declaration (Ex. 1003, ¶¶ 79, 126). Because the plain meaning of “substantially real time” as understood by a POSITA is readily apparent, there is no reason for the Board to consider Patent Owner’s clarification of “substantially real time” based solely on extrinsic evidence, i.e., counsel argument, Mr. Johnson’s declaration (Ex. 2007, ¶¶ 27, 29–30, 33, 39; Ex. 1018, 38:13–39:20) and Dr. McCulloh’s declaration (Ex. 2009, ¶ 19). For example, Patent Owner, relying upon Mr. Johnson’s testimony, clarifies the term “substantially real time” requires either (1) “playback while transmission is ongoing” (PO Resp. 30), or (2) “[a] coordinated system behavior in response to a user’s request” “in which a user request triggers coordinated operations, including locating content across distributed systems, routing that content, and initiating playback while transmission is ongoing” (PO Sur-Reply 4 (citing Ex. 1001, 2:67–3:2, 6:23–35)). However, Patent Owner’s shifting position regarding “substantially real time” is not commensurate with the plain reading of the term. Based on the plain meaning of “substantially real time,” we are persuaded by Petitioner that Yurt explicitly discloses transmitting data at least in “real time,” preferably “less than real time” or “a fraction of real time” for playback. Pet. Reply 9 (citing Ex.1005, code (57), 1:66–2:4, 4:68– 5:3 (teaching distributing “digital audio” in “less than real time” and in “a fraction of real time,” where the receiving system may “decompress in real time the requested material as it is distributed by transmission system 100”)).” slip op. at 36

“teaches or renders obvious all limitations of claim 1, Petitioner also provides sufficient motivation or reasoning with a rational underpinning to combine Yurt and Logan. Specifically, Petitioner, relying on Dr. Lippman’s declaration (Ex. 1003, ¶¶ 62–73), asserts “a POSITA would have been motivated to combine Yurt with Logan for several reasons, discussed further below. Combining Logan’s usage log teachings with Yurt’s improved audio file accessibility (e.g., via popularity) to track additional user request information would have been obvious, beneficial, and predictable.” Pet. 19 (citing Ex. 1003, ¶¶ 62–72). According to Petitioner, because “Logan teaches implementation details for tracking user/usage data for billing purposes and adapting preferences ‘based on actual usage,’” “[a] POSITA would have thus been motivated to combine Yurt’s teachings (e.g., tracking information about requested items like item popularity) with Logan’s teachings (e.g., storing user data and usage information in response to user requests).” Id. at 19–20. “This would have been merely the use of a known technique (Logan’s tracking of user and usage data in response to user requests) to improve a similar method in the same way (Yurt’s tracking of information about user-requested items).” Id. at 20 (citing Ex. 1003, ¶¶ 67– 68). According to Petitioner, [T]he combination is straightforward: use Logan’s known technique for recording user data with Yurt’s existing item database teachings. See Ex. 1005, 12:28–57, 10:66–11:4; Ex. 1006, 5:33–42, 6:27–35, 8:49–58; Pet. 19–23. Since Yurt already teaches using its item database to track item popularity and request information, no modification to Yurt’s architecture is necessary. Logan merely confirms when and how to store the user information. Pet. 19–21. A POSITA would have found the combination obvious for all the reasons Dr. Lippman provided.

In particular, we agree with Patent Owner’s argument that the insulating barriers would be unable to be configured to “block[] substantially all through-air arcing paths between the first and second electrical contacts,” as claimed, unless they were electrically insulating. See Ex. 1001, 4:36–44. Moreover, as Patent Owner avers, our interpretation of “insulating” as it applies to the first and second insulating barriers should be the same as for the first and second housings.

See id. at Fig. 2; Pet. 44–46 (diagrams showing Winkler as modified to have a printed circuit board or wiring board). As such, movement of Winkler’s terminals appears to be mostly limited to within their respective receiving pockets. Given the above teachings, we fail to see how Petitioner’s proposed modification would have meaningfully interfered with the degree of freedom of movement required by Winkler’s terminals. Notably, Mr. Locati’s testimony regarding this issue is conclusory. See Ex. 2001 ¶ 120. Because movement of Winkler’s terminals occurs primarily in the receiving pockets, we also do not discern how the solder joint of Petitioner’s proposed modification would experience undue stress or risk breaking due to that movement. See Ex. 1004, 1:47–55, 3:14–37, Fig. 2; Pet. 44–46. This is particularly true in view of Winkler’s teaching that each cylindrical end portion may be soldered to a cable. See id. at 2:6–10; see also Pet. 43 (arguing that Winkler teaches soldering to a cable but not specifically to a printed circuit or wiring board).

“Record evidence supports Petitioner’s contentions that a skilled artisan would have had reason to look to Kumar for further implementation details of a circuit that performs functions like those performed by Fujiyoshi. See Pet 24–26. For example, Dr. Young testifies that a person of ordinary skill in the art would have recognized that Kumar discloses the details, at a granular level, of Fujiyoshi’s capacitive sensing systems and would have looked to Kumar for understanding of how to implement Fujiyoshi’s system. Ex. 1002 ¶ 145. Patent Owner does not point to persuasive evidence to rebut this opinion. Moreover, Petitioner cites to Kumar, not only for an explicit disclosure of capacitive pickoff signals, but also for its disclosure of both DC bias and AC carrier signals and recognizing the applicability of an AC carrier pickoffs that operates without DC bias. Pet. 24–26 (citing Ex. 1005 3:65–4:2, 6:29–36). We credit Dr. Young’s testimony on this issue and agree with Petitioner that a person of ordinary skill in the art, looking at Fujiyoshi’s description of capacitive sensing systems, would be motivated to look to Kumar for its more detailed teachings of the implementation details of such systems and would combine these details to arrive at limitation 1(a). We determine that Petitioner has shown, by a preponderance of the evidence, that one of ordinary skill in the art would have been motivated to combine Fujiyoshi and Kumar in the manner argued by Petitioner.” slip op. at 37

“during the conference and in the Minute Entry, and in the court’s subsequent Order Regarding Schedule. We also note that the evidence shows the district court may intend to reschedule the trial to a date substantially earlier than March 9, 2026. See Ex. 2010, 5; Ex. 1029, 10−11. However, given that the Order does not unambiguously set a trial date for December 1, 2025, or even sometime in December 2025 or January 2026 (see Ex. 1028), we decline to speculate as to what date the court may ultimately select for trial. Moreover, the record shows that Petitioner has consistently opposed moving the trial to a date earlier than March 9, 2026. See Ex. 2010, 5; Ex. 1026, 2−4; Ex. 1029, 11. We view Petitioner’s opposition as creating yet more ambiguity as to the trial date in the co-pending litigation.

“We agree with Patent Owner that its proffered additional level of ordinary skill in the art appears consistent with the experience Petitioner describes. See Pet. 16. For purposes of this Decision, we adopt the level of ordinary skill in the art articulated by Petitioner and supplemented by Patent Owner, because, based on the current record, it is consistent with our review and understanding of the technology and descriptions in the ’561 patent and prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). We note, however, that the open-ended language “at least” expands the range of education and experience indefinitely with no upper bound.

My work on these joint replacement systems included my direct engagement or supervision of and professionals in the inventing, designing, fabricating, testing, obtaining regulatory approvals, ensuring regulatory compliance, commercializing, and patenting of these systems. Ex. 1002 ¶ 10. Mr. Fallin also testifies that his experience “includes working directly with supervising professionals whose responsibilities included designing, developing, and commercializing joint replacement systems and similar device[s].” Id. ¶ 67 As such, Mr. Fallin identifies “decades” of experience with joint replacement systems. Ex. 1002 ¶ 10. Moreover, Patent Owner does not persuasively explain why Mr. Fallin’s “direct engagement” and “working directly with,” as well as “supervision” of, other individuals designing joint replacement systems, does not at least imply personal design experience. See Prelim. Resp. 10–11. Therefore, we determine that the current record reflects that Mr. Fallin is qualified to testify as to the knowledge of a person of ordinary skill in the art.” slip op. at 20

“Pet. 8–9 (citing Ex. 1004 ¶ 43). Patent Owner’s asserted level of ordinary skill in the art mirrors Petitioner’s except that Patent Owner contends that “a general knowledge of advertising and virtual reality . . . do not specifically apply to the ‘165 Patent.” PO Resp. 5. The ’165 patent claims and describes a “virtual thematic environment” in detail. Indeed, the ’165 patent describes in one embodiment “a method of integrating holographic images into a virtual thematic environment using a computerized system” and “that the computer system of the present invention provides product placement in a virtual thematic environment.” Id. at 3:32–33, 40–45. Although virtual reality and advertising are not claim elements in this case and do not play a specific role in our analysis below, because the ’165 patent specifically contemplates the integration of advertising and virtual environments we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’165 patent and the asserted prior art, and we apply it in our obviousness evaluations below. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art, itself, can reflect appropriate level of ordinary skill in art).

“Having considered the complete record now before us, and where both parties have deferred to the District Court’s constructions, there is no actual dispute as to the meaning of any specific claim terms in this proceeding and we determine that no express additional claim construction is necessary for any particular claim term. Like the parties, for purposes of this Decision we adopt, and where appropriate refer to, the District Court’s claim constructions and also to Patent Owner’s additional interpretations of “client” and “server.” We note that neither “software layer” nor “types,” as set forth in the District Court’s construction of the QIE module is recited in the claims of the ’165 patent. To the extent necessary, we address the terms “types,” “software layer,” “client,” and “server” in our analysis below in the context of the claims and written description of the ’165 patent. See, e.g., Ex. 1001, 12:34–37 (The ’165 patent describing that “[i]n a client-server environment, at least one client and at least one server are each connected to a network such as a Local Area Network (LAN), Wide Area Network (WAN), and/or the Internet, over a communication link.”). We make another observation regarding the claimed “quantum imaging environment (QIE) module” referenced as 202/211 in Figure 2 of the ’165 patent. A QIE is discussed throughout the specification as relating to both a “QIE engine” and a “(QIE) module.” Id. at 6:6, 16:47. Apart from the broad description that QIE 202/211 is a software layer, and includes “an interpreter” which “allows developers to develop objects and applications from the interpreter,” and that the “interpreter [] will take all of the rich content, interpret the information into objects to be manipulated and accessed via any device and place these objects or information in the the software architecture of the QIE itself and how it actually handles, manipulates, or converts information or content into specific formats. Id. at 15:55–59.7 Apart from adopting the District Court’s claim constructions, we need not further expressly construe any claim terms to resolve the parties’ disputes. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (holding that only claim terms in controversy need to be construed, and only to the extent necessary to resolve the controversy (citing Vivid Techs., Inc. v. Am.

“In summary, we find that Pisanich discloses to a person of ordinary skill in the art a computer game system that incorporates real world data into multiple games, and even games with different themes, but not a QIE for accomplishing these tasks for different devices. Ex. 1004 ¶ 17. We find insufficient evidence by Petitioner and Mr. Crane that a person of ordinary skill in the art, considering Pisanich, would have understood that multiple games included multiple games on different devices as required by the District Court’s claim construction of a “QIE module”—that is “a software layer which receives and interprets content such that the content is manipulated so as to be accessible on different types of devices for use within the virtual thematic environment.” Ex. 1009, 4–7 (emphasis added). Independent Claim 18 Independent claim 18 recites the same limitation of “providing a quantum imaging environment (QIE) module in one of the client or the server system” as in claim 1[b]. Consequently, our analysis of the corresponding limitations of claim 1[b] applies also to claim 18. For the reasons given for claim 1, we find that Petitioner has failed to show by a preponderance of the evidence that claim 18 would have been obvious over Pisanich.” slip op. at 36

“prosecution history and the amendment changing “held at” to “accessible at,” testimony upon which Patent Owner relies to support its position. Specifically, Dr. Medvidović testifies that a person having ordinary skill in the art would have understood the two phrases to be synonymous because, 1) the amendment was not made to overcome a prior art reference, 2) the applicant did not make a statement disclaiming that “being accessible at” does not encompass “being held at,” and 3) the examiner did not object to the amendment as exceeding the scope of the Specification. See Ex. 2005 ¶ 34. We find that Dr. Medvidović’s conclusion is not supported by his reasoning. First, an amendment made not to overcome a prior art reference does not mean an amendment that does not change the scope of a claim. An applicant is free to amend a claim at any time during prosecution, even an amendment that may expand the scope of a claim (one made not to overcome a prior art rejection). Second, whether “being accessible at” encompasses “being held at” is not the issue—because the scope of one term encompasses the scope of another term does not make the two terms” slip op. at 26
