    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “Petitioner’s and Patent Owner’s definitions for the level of ordinary skill in the art are substantially similar. In light of the record before us, we adopt Patent Owner’s proposal regarding the level of ordinary skill in the art. Based on our review of the ’898 patent and the prior art of record, we determine that the definition offered by Patent Owner comports with the qualifications a person would have needed to understand and implement the teachings of the ’898 patent and the prior art, particularly experience pertaining to Internet/web interfaces and web-based media. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown”) (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985)). Neither party argues, nor do we determine, that the outcome of our Decision depends on which party’s definition is selected.” slip op. at 11

      “includ[e] a server and one or more webpages that may be provided by the server for display in a web browser.” Pet. Reply 5 (citing Ex. 1026 ¶¶ 13–15). Petitioner argues, and we agree, that the Specification strongly supports this construction (requiring a server and webpage(s)) by describing a “website” as synonymous with a server computer system: “The WWW [(World Wide Web)] service allows a server computer system (i.e., Web server or Web site) to send graphical Web pages or screens of information such as the advertising materials to a remote client computer system 10.” Ex. 1001, 3:66–4:2 (emphases added); see id. at Fig. 1 (depicting a service engine and webpages as a web server, i.e., website), 3:15–18 (describing Figure 1 as showing “a server of the website” (emphasis added)); Pet. Reply 5; see Ex. 1026 ¶ 13. Petitioner also submits a supporting (and persuasive) contemporaneous technical dictionary definition of “website,” which highlights the distinction between a lay person’s understanding of the term versus that of the relevant artisan. Pet. Reply 5–6. This definition explains that the “common but technically inaccurate” usage of “website” is to mean “Web page,” but the technically correct usage of “website” is to mean “one or more computers that are associated with a fully qualified domain name and make content available on the Web.” Id. (citing Ex. 1028, 402). Petitioner’s expert, Dr. Crovella, likewise testifies that “[a] website cannot exist without the server or computer that provides its webpages.” Ex. 1026 ¶ 15; see Ex. 1027, 36:8–20 (Patent Owner’s expert, Dr. Myler, agreeing that “it has to be some machine somewhere that’s providing the webpages for the website.”). The limitations of claim 1 also support Petitioner’s position that “website” includes a server and webpage(s). Reply 5. For example, claim 1 recites advertising material for “populat[ing] on one or more websites,” and selected “advertising buy options comprise at least one website of the respective websites.” Ex. 1001, 10:29–51 (emphases added). We find these limitations make the most technical sense where “website” implicates an Internet domain or domain name, such as brodti.com, which itself is a computer system (server) and associated webpage(s) reached via that domain name. This interpretation aligns with testimony of Patent Owner’s expert, Dr. Myler, in which he states that a “website” describes “a group of webpages at a particular domain (e.g., www.espn.com, www.espn.com/nba, www.espn.com/nfl, www.espn.com/nhl).” Ex. 2009 ¶ 68 (emphasis in italics added). In other words, brodti.com and espn.com are two different websites, with each website having one or more webpages (e.g., www.espn.com/nba, www.espn.com/nfl), and such websites include a server giving life to such webpage(s). slip op. at 15

      “Patent Owner proffers that placing advertising material “within” web property content means “inserting” an advertisement into particular content. PO Resp. 12. Petitioner responds that “placing . . . within” means what it says, and notes that “[t]he words ‘insert’ or ‘inserting’ appear nowhere in the [Specification].” Pet. Reply 7–8; see id. at 8 (Petitioner arguing that Patent Owner’s expert “admitted that the claim does not specify details regarding how advertising material needs to be placed within web property content.” (citing Ex. 1027, 29:18–24)). Patent Owner replies that the relevant artisan allegedly “would have understood ‘placing . . . within’ to mean ‘inserting into,’” but then submits that whether “placing . . . within” versus “inserting into” is used does not matter because Petitioner allegedly has not demonstrated the obviousness of either. PO Sur-reply 17. As Petitioner observes, “[i]t is unclear if Patent Owner intended any difference in meaning between these two terms.” Pet. Reply 8. Accordingly, based on the complete record before us, we determine that no further construction of this limitation is needed, and “placing A within B” means what it says—“placing A within B.”” slip op. at 20

      “determining” of impression validity feature of limitation 1[h] by disclosing “a ‘single-pixel’ image technique for determining that an impression is valid,” e.g., by using “cookies.” Pet. 42–45. Petitioner’s expert, Dr. Crovella, testifies that this “single-pixel” impression tracking technique would have been a “well-known” technique to the relevant artisan, and as described by Error, operates as follows: [A] URL link for a single pixel (or transparent) image file is embedded onto a webpage that is delivered to a web browser. The image is not meant to be viewed and will likely not be visible to the user. After the user’s browser receives the webpage, it uses the embedded URL link to request the single-pixel image from a server. The receipt of that request by the server provides an indication that the user’s web browser actually received and presented the web page to the user.

According to Petitioner, a “person with a different degree but with additional relevant experience could still qualify if the additional experience compensates for the different educational background.” Id. Petitioner also asserts a “person with less than 2 years of experience working in a field involving wireless communications could still qualify if the person has additional education that compensate[s] for their lesser experience.” Id. Patent Owner does not dispute Petitioner’s proposed level of skill. See generally PO Resp. We find that “at least” in Petitioner’s formulation of the level of skill in the art is vague and open-ended. Otherwise, we adopt Petitioner’s formulation of the level of ordinary skill in the art, because it appears consistent with the ’463 Patent Specification and the prior art of record.” slip op. at 8

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

      “We do not agree with Patent Owner’s arguments disputing Petitioner’s backward compatibility rationale for combining the teachings of Yan and Takeda. Patent Owner’s arguments are misplaced because they are premised incorrectly on Takeda’s teachings being limited to 5G NR (i.e., standalone 5G NR), and the proposed combination requiring “mixing standards and behaviors.” To the contrary, Petitioner explicitly asserts that “Takeda states that its teachings are applicable to both 4G and 5G”––i.e., non-standalone 5G. Pet. 14 (citing Ex. 1007 ¶ 239). Likewise, instead of mixing 5G and 4G standards and behaviors as argued by Patent Owner, Petitioner merely proposes retaining Yan’s 4G method of allocating UL channel resources sets with Takeda’s teaching of 5G NR BWPs. See Pet. 14–15. We credit Dr. Roy’s testimony that a person of ordinary skill in the art would have been motivated to modify Takeda’s teachings with Yan’s teachings to provide Takeda with backwards network capability because it is supported by the cited evidence of record. See Ex. 1002 ¶¶ 105, 106 (citing Ex. 1007 ¶ 239; Ex. 1031, 1, 3; Ex. 1033, 5:23–31; Ex. 1034, 10; Ex. 1035, 1, 5; Ex. 1037, 31). Moreover, as pointed out by Petitioner, Dr. Shimony’s deposition testimony regarding the usefulness of backward compatibility and the importance of a non-standalone UE having the ability to communicate over both 4G and 5G standards supports Dr. Roy’s testimony, yet undermines Patent Owner’s arguments. See Ex. 1050, 178:16–182:16; Pet. Reply 14–15. Based on the entire record developed during trial, we are persuaded by a preponderance of the evidence that Petitioner provides sufficient articulated reasoning with rational underpinning to support the conclusion that it would have been obvious to a person of ordinary skill in the art to modify Takeda’s teachings with Yan’s teachings to provide Takeda with backwards network compatibility.10 See Pet. 13–15; KSR, 550 U.S. at 418.” slip op. at 15

      “The parties have not addressed whether the differences in these definitions impact the unpatentability analysis before us.

      “And Patent Owner states that it “agree[s] with Petitioner’s construction” with respect to the MPF terms. PO Resp. 13. Although Patent Owner also contends that a “POSITA would understand the ‘means for transmitting’ to be a socket server transmitting through an event socket that implements the algorithms described in Figures 2, 3, 21A–21E and accompanying disclosures” (id.), Patent Owner’s proposed further construction is not disputed by Petitioner. See generally Pet. Reply. Furthermore, Petitioner’s proposed constructions of “socket” and “event socket” (Pet. 39) are not disputed by Patent Owner. PO Resp. 2, 13–14. In fact, by arguing that Spivey’s topic queues are neither “uniquely addressable” nor “communication endpoint[s],” Patent Owner appears to adopt Petitioner’s proposed construction of “socket” as a “uniquely addressable communication endpoint.” Id. at 2. As Patent Owner acknowledged during Oral Argument, “I don’t think there’s any dispute of what we mean by socket, a uniquely addressable communication endpoint.” Tr. 73:11–13.6 Thus, on this record, because there is no dispute between the parties regarding the terms “means for transmitting,” “event socket,” or “socket,” construction is not needed. Accordingly, we decline to provide further analysis or an express construction for these terms.” slip op. at 14

      “ability for the clients and the server to communicate,” which can be any system that can “provide real-time sports,” but “doesn’t discuss whether it’s a push system or a pull system,” wherein Spivey, on the other hand, “expressly indicates that it is a push type of data system which reduces latency over prior art systems that utilize push technologies.” Tr. 15:13–19. We find availing Petitioner’s contention that, “[a]s explained by Dr. Wicker, . . . a POS[IT]A would have been motivated to implement real-time data delivery using Spivey’s data pushing technique to reduce latency.” Id. at 16:2–4. “[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. We find unavailing Patent Owner’s contention that Petitioner fails to “articulate why a POSITA would have been motivated to make the necessary modification and proposed combination.” PO Resp. 44. Here, Petitioner points out that its proposed combination would have been made to improve latency issues in Ellis’s system. Pet. 19–24. In particular, Spivey’s discloses that its techniques “may reduce . . . delay [on the order of seconds (e.g., 30 to 45 seconds) or minutes] to an order of milliseconds (ms) (e.g., 100 ms) or less, providing a significant advantage over the conventional practices.” Ex. 1017 ¶ 28. Spivey also discloses pushing data to the “subscribed connected client devices” substantially simultaneously with the message queue server receiving the topic entry from a live data source, e.g., “with a time delay of 100 milliseconds or less,” which Spivey discloses is “at least two orders of magnitude shorter than conventional time periods of legacy devices.” Id. ¶ 96; see also id. at code (57) (disclosing pushing “the topic entry to a subscribed client device substantially simultaneously with the message queue server receiving the topic entry from a live data source”).” slip op. at 51

      “demonstrated that a long-felt but unresolved need existed for the claimed invention. See Apple v. Samsung, 839 F.3d at 1056. As Petitioner points out, although Patent Owner argues that there is a long-felt need for a system that “allows broadcasters to deliver synchronized, low-latency video and audio content. . . . ” (PO Resp. 66), Patent Owner does not contest Petitioner’s showing that Ellis also discloses “a video streaming system that provided event information over a separate channel, which is not hard embedded in the video stream.” Pet. Reply 22–23. Further, as Petitioner also points out, “claim 19 simply requires a media source to receive the live stream of digital content and distribute it.” Pet. Reply 23. In fact, during Oral Argument, although Patent Owner argues that its invention is “the synchronization and the latency improvements through that one-to-many socket architecture,” Patent Owner conceded that the claims “could be broader than that.” Tr. 44:24–46:16. We find availing Petitioner’s argument that the “claim language” does not “relate to any synchronized, low-latency, scalable, flexible, or new and improved video streaming technique.” Pet. Reply 23. Nevertheless, as Petitioner points out, Patent Owner does not cite to any evidence as to any long-felt but unresolved needs. Pet. Reply 23 (citing PO Resp. 67–68). In particular, Patent Owner merely provides conclusory statements that, prior to the claimed invention, “conventional video streaming systems” include “hard-embedded event information,” and that “[t]he claimed invention satisfied the long-felt need for an innovative system.” PO Resp. 66–68. Thus, considering the totality of the evidence, we agree with Petitioner that Patent Owner has failed to establish that there was a long-felt but unresolved need for the claimed invention.” slip op. at 59

Additional professional experience might substitute for less education and vice versa. Pet. 10–11 (citing Ex. 1011 ¶¶ 33–35). Patent Owner, at this stage, does not disagree or propose a different definition of the person of ordinary skill in the art. However, Patent Owner’s proffered declarant, Dr. Noubir, opines that “a person of ordinary skill in the art in March 2003 would have a bachelor’s degree in computer science or electrical engineering, and would have one or two years of experience in computer networking or equivalent educational and professional experience.” Ex. 2008 ¶ 53. We discern no material difference between the two definitions. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v.

Patent Owner asserts that “a person of ordinary skill would read ‘a domain name’ in its ordinary networking sense: an ASCII string label used with the Domain Name System (DNS) to resolve to an IP address.” Prelim. Resp. 16 (citing Ex. 1001, 1:47–48; Ex. 2008 ¶ 37). This is consistent with the Specification, which explains: Users and software applications do not always refer to hosts or other resources by their numerical IP address. Instead of using numbers, they use ASCII strings called domain names. The Internet uses a Domain Name System (DNS) to convert a domain name to an IP address. Ex. 1001, 1:45–50. According to the Patent Owner, the network in the Specification of the ’785 patent is defined by the domain name X.VCN. Id. at 33 (citing Ex. 1001, 9:18–19, 9:28–31). Patent Owner further contends that “[t]he use of a domain name to define the virtual network in the ‘785 Patent’s claims provides more than an identifier of the virtual network or even a plain language identification of an IP address – it signifies a hierarchical structure for the virtual network that enables [certain functions].” Prelim.

Rather than explaining the “why,” the Petition’s motivation argument focuses on the purported capabilities of the resulting combination and implying, but not explicitly stating, that the combination results in the claimed subject matter; this indicates impermissible hindsight. See, e.g., id. at 29 (“This integration would leverage Hipp’s DNS capability for virtual hostnames to return multiple address records from a single query, aligning with the dual addressing requirements of hybrid virtual/physical networks. The combination creates a cohesive system where DNS resolution triggers context-aware routing decisions—using virtual addresses for internal Supernet traffic and NAT-translated addresses for cross-boundary communication.”). We determine that Petitioner has failed to set forth an adequate and persuasive reason with rational underpinning as to why a person of ordinary skill in the art would have combined the three references’ teachings to arrive at the claimed subject matter where the three recited addresses are returned in response to a DNS request.” slip op. at 21

    Claims 2–23, 26, 41–60, 63, 64, 91–152, and 155–171 are unpatentable; Rao anticipates some claims, and the stated Rao combinations render the remaining claims obvious.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Petitioner argues that a person having ordinary skill in the art “would have at least a bachelor’s degree in computer science, computer engineering, or a similar field, and approximately two years of industry or academic experience in a field related to computer software development and/or computer networking.” Pet. 2 (citing Ex. 1015 ¶¶ 50–52). Petitioner further argues that “[w]ork experience can substitute for education, and additional education can substitute for work experience.” Id. at 2–3 (citing Ex. 1015 ¶¶ 50–52). Because Petitioner’s proposed level of ordinary skill in the art is consistent with the field of the invention of the ’541 patent and not disputed by Patent Owner (see PO Resp.), we adopt Petitioner’s formulation of the person having ordinary skill in the art.” slip op. at 12

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “In summary, the extrinsic record shows that, in the context of wireless network communications using the IEEE 802.16 standard, a “mobile device” is distinct from and excludes a device that is “fixed” or “portable,” where a “mobile” device is described as a device that is mobile during wireless network communications, and a “fixed” or “portable” device is described as a device that is fixed or slowly moving during wireless network communications. See Ex. 1005 ¶ 11; Ex. 1025, 24, 34, 38, 45; Ex. 2025, 71. This understanding of a “mobile device” from the extrinsic record is consistent with the language of claim 7 which recites a mobile device configured for wireless network communications (e.g., receiving an identifier and a signal from a base station), and consistent with the ’450 Patent disclosure that repeatedly and consistently utilizes the term “mobile device.” Accordingly, based on the record, we construe “mobile device” as a device that is mobile during wireless network communications, and is not fixed or slowly moving during wireless network communications.” slip op. at 19

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “We do not agree with Petitioner’s arguments because, as explained above in Section III.B., we construe “mobile device” as a device that is mobile during wireless network communications, and is not fixed or slowly moving during wireless network communications. Thus, after having considered both parties’ arguments and the cited supporting evidence, we are not persuaded that the combination of Park and IEEE 802.16-2004, including the application of Park to WiBro’s teaching of stationary or slowly moving devices communicating using band AMC, teaches or suggests a “mobile device,” as properly construed, that is configured to perform the limitations recited in the body of claim 7.” slip op. at 36

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “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. Cir. 1995) (citation omitted). Considering the subject matter of the ’898 patent, the background technical field, the prior art, and Petitioner’s proposed and unopposed definition of the skilled artisan (Ex. 1002 ¶¶ 9–12), we apply the level of skill set forth above.” slip op. at 11

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction needed

      “Petitioner submits that all terms in the Challenged Claims should be given their plain and ordinary meaning in this proceeding, and that no specific construction of any claim term is required to resolve this case. Pet. 6 (“Petitioner does not believe express claim construction is necessary to resolve this Petition.”). Patent Owner has not submitted a preliminary response, and thus does not propose any terms for construction at this stage. In determining that Petitioner has demonstrated a reasonable likelihood of establishing unpatentability of at least one Challenged Claim, we need not and do not construe expressly any claim terms. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “Petitioner argues the skilled artisan would have had various rational reasons for combining the teachings of these four references, and would have had a reasonable expectation of success in doing so. See, e.g., Pet. 18–21 (discussing reasons to combine Nicholas and Laidlaw and expectation of success in doing so), 33–37 (discussing reasons to combine Nicholas and Mayadas and expectation of success in doing so), 44–45 (discussing reasons to combine Nicholas, Laidlaw, Mayadas, and Error and expectation of success in doing so). Based on the record before us, we find Petitioner sufficiently shows that the combination of Nicholas, Laidlaw, Mayadas, and Error would have taught or at least fairly suggested to the skilled artisan the limitations of claim 1.4 Thus, for the reasons stated in the Petition (Pet. 8–51), we determine that Petitioner has established a reasonable likelihood that it would prevail in showing that independent claim 1 would have been unpatentable as obvious over the combination of Nicholas, Laidlaw, Mayadas, and Error.” slip op. at 21
