    “1. Principles of Law A claim is unpatentable under § 103 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 said subject matter pertains.” 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, including (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 skill in the art; and (4) when in evidence, objective indicia of obviousness or non-obviousness (i.e., secondary considerations, such as commercial success, long-felt but unsolved need, failure of others, etc.).5 Graham v. John Deere Co. of Kansas City, 383 U.S. 1, 17–18 (1966). We analyze the asserted grounds based on obviousness with the principles we identify above in mind.” slip op. at 9

Relying on the testimony of Dr. Polish, Google argues the following: [a] person of ordinary skill in the art . . . would have possessed at least a bachelor’s degree in computer science, computer engineering, electrical engineering, or an equivalent field requiring learning computation principles, and two years of work experience in networking or streaming media systems, particularly audio and video, over the Internet.

    “In the Petition, Google states that it “does not presently contend that any [claim] term requires express construction.” Pet. 6.

    “Turning to rationale to combine, Google contends that Carmel and Mattavelli are both directed to processing multimedia data playback “for the appreciation of a user,” while providing the highest perceived audio and video output quality possible in view of system constraints to ensure playback continuity. Pet. 50–51 (citing Ex. 1003, 10:48–54, 11:9–18, 7:35– 49, Figs. 3D, 6B; Ex. 1004, 2309, 2310). Google argues that both Carmel and Mattavelli pertain to compression of multimedia data using well-known coding and compression standards for video streaming. Pet. 51 (citing Ex. 1003, 7:25–26, 11:24–52; Ex. 1004, 2309–2311). Google argues a PHOSITA would appreciate both Carmel and Mattavelli complement each other because Carmel pertains to addressing constraints to available network bandwidth, whereas Mattavalli relates to addressing limits on available processing resources at the client/multimedia player. Pet. 52 (citing Ex. 1003, Abstract, 7:36–41; Ex. 1004, 2309–2312). Google argues that a PHOSITA would have been motivated to combine the complementary teachings in Carmel and Mattavelli to create a more robust streaming system that addresses both bandwidth constraints and client processing limits to provide a best possible playback experience. Pet. 52 (citing Ex. 1002 ¶¶ 212–215). Google argues that Mattavelli teaches merely optimizing transmission bandwidth is not sufficient and is potentially harmful, which provides an express motivation to combine Carmel’s and Mattavelli’s complementary teachings to ensure that different, related links in the streaming playback chain are optimized together. Pet. 53 (citing Ex. 1002 ¶¶ 216–217; Ex. 1004, 2310). In addition, Google argues Carmel contains an express disclosure that would have motivated a PHOSITA to combine Carmel with Mattavelli’s complementary teachings because Carmel states that multimedia playback is achieved “preferably with only a minimal necessary transmission and decoding delay.” Pet. 53–54 (citing Ex. 1002 ¶ 218; Ex. 1003, 10:50–54). Withrow does not specifically respond to these arguments, except for limitations 1[c.ii] and 1[c.iv] discussed infra. See generally Prelim. Resp. Nonetheless, the burden of persuasion remains on Petitioner to demonstrate unpatentability. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). Based on the preliminary record, we discern no deficiency in Google’s characterizations of Carmel, Mattavelli, or the general background knowledge in the art. In addition, for purposes of institution, we are persuaded by Dr. Polish’s testimony concerning the relevant disclosures in Carmel and Mattavelli.” slip op. at 22

Instead, it describes “an additional configuration to select a representation based on a user characteristics and terminal characteristics.” Ex. 2004 ¶ 232. It is unclear from Patent Owner’s argument whether Patent Owner intends for the claimed “user characteristic information” to include or refer to additional configuration information, accessibility features of a representation, or both. Reply Rev. Opp. 1 (citing Ex. 2004 ¶¶ 232, 234, 253). In any event, merely because paragraph 253 uses the term “[h]ereinafter” before it discloses “two simple attributes [] for the above-described purpose”––and not even in close proximity to the “user characteristics” and “additional configuration” in paragraph 232––is not sufficient to provide support for “the user characteristic information includ[ing] the usedWith attribute and the equivalentTo attribute,” as recited 8 Ex. 2005 is Application No. 16/168,933 (“the ’933 application”). in limitations [38.6], [40.6], and [46.6].

    “rationale for combining DIS 23009-1 with M20060, Petitioner persuasively contends that: A POSA would have been motivated to add the additional “metadata” described in M20060 to the MPDs described in the DIS 23001-6 or DIS 23009-1 references in order to enable the client to choose the most suitable version of media content among alternative versions of media content. For example, M20060 describes that the additional metadata (e.g., the extended accessibility element and the usedWith, equivalentTo, bitDepth, minBitDepth, and maxBitDepth attributes) helps “both users and clients to select appropriate representations” by, for example, “1) supporting accessibility, 2) describing relationships of representations, and 3) describing media’s bit depth.” Moreover, a POSA would have had an expectation of success in modifying the MPDs in DIS 23001-6 or DIS 23009-1 to include the additional metadata described below because it simply would have been a matter of adding additional metadata to the MPD XML schemas described in DIS 23001-6 or DIS 23009-1.

    “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.

Patent Owner does not address this issue in the Preliminary Response.

Patent Owner also argues that “[t]he terms “provisioning, . . . based on the determined correlation, . . . rules configured to identify the first plurality of packets received by the network device,” and “provisioning, . . . based on the determined correlation, . . . rules configured to identify the second plurality of packets transmitted by the network device” (“provisioning rules”) . . . should be given their plain and ordinary meaning—rules configured to identify packets.” Prelim.

    “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. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (“It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’”) (quoting 35 U.S.C. § 312(a)(3)); 37 C.F.R. § 42.104(b). 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

    “We agree with Patent Owner that the Petition’s avoidance of the operation of edge caches when edge caches are important in the processing of traffic flowing across the boundary undermines this ground of the Petition. If Petitioner wished to rely on an embodiment or configuration in which the edge caches were irrelevant, the edge caches were redundant to the edge server, or the edge caches were unnecessary, it was incumbent upon Petitioner to explain sufficiently how and why that was the case. Petitioner was aware of the edge caches because it appears to have omitted all references to them in the Petition yet did not explain why this was done. Additionally, although Petitioner’s declarant does include references to edge caches, its declarant also does not explain sufficiently the relevance of those edge caches. Ex. 1004 ¶¶ 148, 212, 214, 215, 227, 323.

    “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)).

(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.

Although, Petitioner does submit that, “[f]or purposes of this IPR only, Petitioner relies on the claim scope positions Patent Owner has advanced in district court for ‘port definer module.’” Pet. 8. Similarly, Patent Owner argues each claim term should have its ordinary and customary meaning, except that, as in the parallel district court proceeding, the function of alleged means-plus-function term “port definer module” should be construed to be “designating any one physical link of the logical link and examining the designated link of the logical link.” Prelim.

    “Petitioner argues it would have been obvious to a person of ordinary skill in the art to combine Jaso and Stine1998 “to etch a plurality of dummy trenches in a dielectric layer between a first (wider) trench and a series of second (narrower) trenches.” Id. at 66 (citation omitted). Petitioner argues that a person of ordinary still in the art “would be motivated to combine the teachings in Jaso and Stine1998, as both references are directed to the addition of dummy conductors to equalize pattern density to improve CMP planarity.” Id. at 38–39 (citing Ex. 1004, code (57), 3:29–64; Ex. 1005, 668). In particular, Petitioner states that “Stine1998 enhances and improves upon the disclosure in Jaso by providing general teachings and specific methods that are widely applicable to dummy metal-fill techniques for addressing added capacitance.” Id. at 39 (citing Ex. 1005, 670–672). Petitioner points out that “Stine1998 expressly motivates a [person of ordinary skill in the art] to apply its teachings to a damascene process requiring dummy-fill to enhance planarity” because Stine1998 states its methodology can be extended to “inlaid metal techniques such as copper (emphasis omitted). Analysis of Patent Owner’s Arguments 1) Prior Art Does not “Look for” a Specific Configuration Patent Owner argues “Stine1998 does not tell the POSA to look for a specific configuration of structures, and then insert dummy metal into a particular location within that configuration (as the Relevant Solution does.)” PO Resp. 36–37. Patent Owner also argues that Jaso and Stine1998 “together accordingly tell the POSA to focus on pattern density, and to take steps to ensure that variations in pattern density across the chip are minimized” as opposed to looking for the particular configuration called out by the claims. Id. at 58. There is no requirement in the claims for the prior art to “look for” specific structures, but rather it must disclose those structure required by the claims. For the reasons articulated in the Petition, we agree that the combined teachings of Jaso and Stine1998 teach the structure required by claim 1.

We also credit Dr. Boning’s testimony that these references’ teachings “to locate dummies in sparse regions proximate to wide and narrow lines...would obviously include placing dummies in regions between such lines.” Ex. 1002 ¶ 183 (emphasis added). The fact that Jaso and Stine1998 may not purposefully seek out the configuration relied on by Patent Owner does not undermine Petitioner’s showing that the proper configuration would result from an obvious combination of the references.

    “a. Centralized Caller profile System Patent Owner argues “Centralized Caller Profile System,” recited in the preamble of independent claims 1 and 11, is limiting and refers to caller profiles in a central location accessible and revisable by multiple parties. PO Resp. 8–9. According to Patent Owner, unlike caller profiles traditionally stored at a single location, the caller profiles are stored at a centralized database accessible and updatable by the user and authorized third parties (e.g., user’s agent, service provider). Id. at 9–10 (citing Ex. 2005 ¶¶ 40–44). Accordingly, Patent Owner submits that, as acknowledged by Petitioner, “Centralized Caller Profile System” encompasses not only caller profiles located at a single location, but also that which is accessible and revisable by multiple parties.

Patent Owner therefore argues that Petitioner’s contention that the preamble is not limiting for lack of antecedent basis, and relates merely to a location (e.g. centralized or on the cloud) is not persuasive because it overlooks the ’612 patent’s description that the “Centralized Caller Profile System” permits multiple parties to access the database. Id. at 11–12, Sur-Reply 2–4. In response, Petitioner reasserts that the preamble is not limiting because it does not provide antecedent basis for and does not breathe meaning into the claims. Pet. Reply 3, Pet. 25. According to Petitioner, because the proposed construction of the preamble is already recited in the claim, namely “the Cloud Database is maintained [(meaning ‘accessible and revisable’)]” by each of a service provider, user, and third party, the reading of the preamble into the claim is duplicative and thereby non-limiting. Pet. Reply 3. We agree with Petitioner insofar as it is undisputed by the parties that the claim, as a whole, requires the Centralized Caller Profile System that comprises the Cloud Database including contents, which are maintained (i.e., accessible and revisable) by each of a user, a service provider, and a third party.

Patent Owner further directs our attention to a single sentence of deposition testimony in which Petitioner’s declarant Dr. Szepesi appears to agree with Patent Owner’s construction by stating, in the context of claim 9, that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” PO Resp. 8 (citing Ex. 2003, 44:16– 45:1). Petitioner rebuts Patent Owner’s arguments by identifying additional deposition testimony and statements made in a second declaration offered by Dr. Szepesi opposing Patent Owner’s construction. Reply 2–3 (citing Ex. 1016 ¶¶ 18–21, 26–30; Ex. 2003, 43:16–45:1). For instance, immediately before the statement Patent Owner cites, Dr. Szepesi testified: Q: “So is it your opinion that an output for disabling the pulse generator must disable the pulse generator regardless of the other conditions in the circuit?” . . . A: “I don't understand your question. I said disabling the pulse generator means that the output of the pulse generator which is providing the pulses to the gate of the main switch, those pulses are disabled. That’s what it means in my opinion in this context.” Ex. 2003, 43:24–44:9. And, in his supplemental declaration, Dr. Szepesi states: As a first matter, I opined during my deposition that “an output disabling a pulse generator” means that “the output signal of this first comparator disables the output pulses driving the gate of that independent of anything else.” But, at the time of my deposition I had not done a focused claim construction analysis of the limitation “a first comparator […] having an output for disabling the pulse generator.” This is because I hadn’t anticipated there being a dispute relevant to the validity analysis in view of what I understood as the plain meaning of the language. Despite the quote that Patent Owner relied upon, I believe now that a POSITA would not understand the claim language to require the first comparator to disable the output pulses independent of anything else. This belief is consistent with my responses to the first two of three successive questions in which I was asked about “disabling the pulse generator.” It is my opinion that the operation of the disclosed embodiment requires the presence of other conditions precedent before the first comparator can disable the drive pulses and this requirement is not excluded by the claim language. Ex. 1016 ¶ 18 (emphasis added). Our reviewing court has made clear that extrinsic evidence “is generally of less significance than the intrinsic record” in matters of claim construction. Wi-LAN, Inc. v. Apple Inc., 811 F.3d 455, 462 (Fed. Cir. 2016) (citation omitted). Here, beyond competing declarant testimony, neither party has entered into the record extrinsic evidence, such as dictionary definitions or contemporaneous usage in the art, addressing the scope of “in response to.” Having considered the testimony upon which Patent Owner relies and weighing it against the claim language itself, the Specification’s disclosures set forth above, and the contrary testimony of Petitioner’s declarant, we find on balance that it does not warrant departing from the plain and ordinary meaning of “in response to” as Patent Owner urges. See In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994) (holding that an inventor may define specific terms used to describe invention, but must do so “with reasonable clarity, deliberateness, and precision”) (quoting Intellicall, Inc. v.

As discussed above, we decline to import into claim 4 a requirement that the claimed disabling must occur independent of other circuit conditions. See supra Section III.C.1. Because Patent Owner’s argument relies on a claim construction that we rejected above, we are not persuaded that Hwang fails to meet the limitations of claim 4. Rather, having reviewed the evidence cited by Petitioner, we agree with Petitioner that Hwang discloses the limitations of independent claim 4, arranged as recited in the claim.

You don't have an opinion that a POSA would have been motivated to use Hsu only when Franaszek has a data type, but would not have been motivated to use Hsu when Franaszek doesn't have a data type, right? A. I don't believe that I expressed an opinion on that in my declaration. Ex. 2003, 130:18–131:12 (emphases added).” slip op. at 26

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.
