“Figure 3 above is an example of the embodiment of Ho showing a wings button, a car, and a hamburger monster in the foreground. Ex. 1004, 5:1–5, Fig. 3. Ho describes how the various interactive information elements are used for game play. See id. at 5:11–38. For example, hamburger monster 56 may be engaged when character 52 fights and successfully slays the hamburger monster, car 58 may be engaged when character 52 enters the car, and “wings” button 54 may be engaged (for example when character 52 wishes to fly) by clicking on icon 54 using a pointer, or by using an enclosure moving between different icons to highlight icon 54 to engage the icon. Id. Because Petitioner has not shown persuasive evidence that a user would not have expected those objects to be ones that the user could interact with, Petitioner has not shown them to be background objects. Petitioner also argues that Ho teaches that activating the interactive information elements “does not disrupt gameplay” and is therefore “outside the primary focus of game play.” Pet. 31–32 (quoting 5:36–38). We do not find that argument persuasive for two reasons. First, we do not see how the fact that activating an element without disrupting game play means the element is in the background. Petitioner and its expert simply make a statement without any explanation. See id.; Ex. 1003 ¶ 122. Such conclusory statements are not persuasive. Second, the language in Ho Petitioner relies on is not about the interactive information element, which Petitioner maps to the hotspot. Instead, Ho describes a sub-screen that appears after the user interacts with one of the interactive information elements, namely when the user slays the hamburger monster: “Similarly, making the character 52 slay the hamburger monster 56 may generate a sub-screen showing an advertisement of a chain of fast food restaurants. The sub-screen may also be overlain on the game environment and may not be disruptive to gameplay.” Ex. 1004, 5:35–38. Petitioner does not persuasively explain how a nondisruptive sub-screen that appears after an interaction with an object makes the object a background object.” slip op. at 23

“Obviousness Analysis A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which the subject matter pertains. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, primarily: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness. Graham, 383 U.S. at 17–18.6 Petitioner asserts that claims 1–2, 7–8, 10, 12–13, and 17–18 are unpatentable under § 103 as obvious in view of Paxton and Sutton. See Pet. 6, 18–64.

“c. Summary of Claim 1 In sum, Petitioner does not explain how the edge cache devices contribute or detract from Jungck’s ability to teach or suggest the “entire boundary” and “all traffic” limitations of the challenged claims. The evidence of device 900 and claims of collateral estoppel do not remedy this deficiency. In the absence of such evidence, Petitioner has failed to “identif[y], in writing and with particularity, . . . the evidence that supports the grounds for the challenge.” See Intelligent Bio-Sys., Inc. v.

For the reasons above, Petitioner has not shown sufficiently that the combination of Jungck and Wood meets the limitation of “[a] method of filtering packets at a packet security gateway, of a plurality of packet security gateways that collectively provide an entire interface across a boundary of a network protected by the packet security gateway . . . comprising: a first set of packet filtering rules to be applied to all network traffic traversing the boundary.”” slip op. at 24

“Patent Owner requests that the preamble of independent claims 1, 8, and 15 be treated as limiting. Prelim. Resp. 16–17. These preambles provide antecedent basis for “packet security gateway,” “boundary,” “network,” and “one or more other networks.” Id. at 16 (citing Ex. 1001, 20:64–21:2, 22:13–18, 23:35–42). The preambles also recite the “plurality of packet security gateways that collectively provide an entire interface across a boundary of a [protected] network,” which is “essential to understand” the “all traffic” limitation in the body of these claims and thus ‘“give life, meaning, and vitality”’ to the claims. Id. (citing Catalina Mktg. Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) (citation omitted)). The preambles provide the context for the body of the independent claims by defining the arrangement of the “plurality of packet security gateways” relative to the “boundary” of the protected network and thus the basis for applying “packet filtering rules . . . to all network traffic traversing the boundary.” Id. (citing Ex. 1001, 20:64–21:8). The “entire interface” limitation also was relied on during prosecution of the parent ’437 Patent’s claims to distinguish them from the prior art. Id. at 16–17 (citing Ex. 2008, 254–61; Catalina, 289 F.3d at 808–09). Petitioner does not dispute the preambles are limiting. Pet. 18–21, 37. For, the reasons above, we construe the preambles of independent claims 1, 8, and 15 as limiting. After review of the current record, we conclude that, other than determining the preambles are limiting, no express claim construction is necessary to determine whether to institute review of the challenged claims. See, e.g., 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)) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’”).” slip op. at 7

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
