A person of ordinary skill in the art with a higher level of education may have fewer years of academic or industry experience, or vice versa. Pet. 22 (citing Ex. 1002 ¶ 10). Patent Owner does not contest Petitioner’s articulation of the level of skill in the art. PO Resp. 4–5. We regard Petitioner’s definition as consistent with the prior art before us. See Okajima v.

“embodiments that operate with a low frequency driving signal in a double-ended configuration, Patent Owner did not recite “low frequency” or “double-ended” in its claims and instead chose the broader term “first driving mode.” See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). The fact that a limitation in the specification may define over the prior art does not justify importing that limitation into the claims unless a term is expressly defined such that the patentee becomes his own lexicographer or there is an express disavowal of claim scope. See GE Lighting Sols., LLC v. AgiLight, Inc., 750 F.3d 1304, 1308–09 (Fed. Cir. 2014). There is no evidence of an express disavowal here. As to lexicography, we disagree with Patent Owner’s contention that the Specification defines the phrase “first driving mode.” Patent Owner relies on the mere fact that the specification describes an embodiment with a first driving mode that has a low frequency driving signal and is in a “double-ended” configuration, but this is not sufficient to define the term. The specification does not require that a low frequency driving signal must necessarily be used. In fact the specification, although not entirely clear, suggests that the driving signal may be from a high frequency ballast. Ex. 1001, 51:8–14. Thus, the fact that the patent here discloses a low frequency driving signal does not mean that all the claims are directed to such a driving signal. See E-Pass Tech., Inc. v. 3Com Corp., 343 F.3d 1364, 1368–69 (Fed. Cir. 2003). Indeed, dependent claim 15 recites “the first driving mode is performed when the external driving signal is a relatively low frequency or voltage signal,” while the independent claims were directed to a more general driving signal. The doctrine of claim differentiation suggests that the independent claims here should not include explicit limitations of a dependent claim. See Phillips, 415 F.3d at 1315 (“[T]he presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim.”); Liebel-Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 910 (Fed. Cir. 2004).” slip op. at 7

The evidence of device 900 and claims of collateral estoppel do not remedy this deficiency.

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.

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.

“Whether or not this was known as a general proposition does not address reasons why Jungck’s traffic appears to bypass the edge servers upon which Petitioner relies and why a person of ordinary skill would have modified Jungck’s operation to apply its rules to all traffic or why a person of ordinary skill would have modified Jungck’s operation to use device 900 instead of the edge servers and what effect that would have on the rest of the operation of Jungck. Petitioner also appears to rely on its declarant who testifies it was well-known to block all incoming traffic. Fintiv Reply 9 (citing Ex. 1004 [Declaration of Dr. Vijay Madisetti] ¶¶ 72–73). Nevertheless, this section of the Declaration was not cited in the Petition but rather is referred to indirectly in a portion of the Declaration which is cited in the Petition. Pet. 44 (citing Ex. 1004 ¶ 241). Paragraph 211 of the Declaration states “[a]s also discussed in Section IV, the use of block lists (e.g., blacklists) to perform packet filtering, including both ingress and egress filtering, was well-known,” but does not refer to paragraphs 72 and 73. Ex. 1004 ¶ 211 (emphasis added). As the Court of Appeals for the Seventh Circuit has explained, “[a] brief must make all arguments accessible to the judges, rather than ask them to play archaeologist with the record.” DeSilva v. DiLeonardi, 181 F.3d 865, 867 (7th Cir. 1999); see also United States v. Dunkel, 927 F.2d 955, 956 (7th Cir. 1991) (“Judges are not like pigs, hunting for truffles buried in briefs.”). Additionally, paragraph 72 of the Declaration contains new argument regarding “firewall” and “standard networking practice” based on references (Bharali and Wood) not cited for that proposition in the Petition. Ex. 1004 ¶ 72. We find the Petition improperly incorporates this section of the Declaration by reference because the basis of the “firewall” argument is not explained sufficiently in the Petition.

We further find that Patent Owner’s argument during prosecution that the packet transformation function is configured “to prevent an exfiltration operation” resulted in allowance of the claims of the ’343 patent, which overlaps with the argument that Patent Owner makes in this case against Petitioner’s challenges. Prelim. Resp. 35–36. Petitioner has not shown that the two-stage filtering process was a basis for the Examiner’s allowance of the claims of the ’343 patent over the cited prior art.

“extent to which additional evidence and facts presented in the Petition warrant reconsideration of the prior art or arguments. Petitioner’s declarant testifies regarding the prosecution history of the ’343 patent. Ex. 1003 ¶¶ 85–90. He concludes that “the ’343 Patent claims were apparently allowed because the Examiner concluded that the prior art of record failed to disclose a two-stage packet filtering process,” mirroring Petitioner’s argument. Id. ¶ 90. Petitioner’s declarant does not indicate how the facts support this conclusion. As mentioned, Patent Owner’s argument during prosecution leading to allowance was that the ’343 patent’s claims recite applying the packet transformation function configured to prevent an exfiltration operation. Ex. 1002, 1614–1615, 1639. Petitioner’s declarant does not explain sufficiently where in the prosecution history Patent Owner argued that a two-stage packet filtering process distinguished the ’343 patent’s claims over the prior art, or where the Examiner allowed the claims because of two-stage packet filtering. Accordingly, lacking evidentiary support, the declarant’s testimony is entitled to little or no weight on this point. 37 C.F.R. § 42.65(a). Thus, we see no additional evidence or facts in the Petition that warrant reconsideration of the prior art. Therefore, we find that Petitioner has not demonstrated that the Office erred in a manner material to the patentability of the challenged claims under the second part of the Advanced Bionics framework.” slip op. at 18

“Here, as explained below in Section III.E.2., under either articulation of the level of skill in the art Petitioner has shown the claims would have been obvious.

“Petitioner asserts “for the purposes of this proceeding and the analysis presented herein, no claim term requires express construction [and that it] analyzes the claims consistent with ordinary and customary meaning as would be understood by a POSITA in light of the specification.” Pet. 8. Patent Owner does not request construction of any claim term. See generally PO Resp. 12 12 Patent Owner proposed a construction for the limitation “no-switching criterion,” as recited in each of the challenged claims in its Preliminary Response. Prelim. Resp. 7–8. Patent Owner asserted “no-switching criterion” should be construed as “one more criteria determined based on inputs obtained from the two camera images.” Id. at 7. In the Institution Decision, we did not limit “no-switching criterion” to “one more criteria determined based on inputs obtained from the two camera images.” Patent Owner did not address claim construction in its Patent Owner Response. See generally PO Resp. Our Scheduling Order states that “Patent Owner is cautioned that any arguments not raised in the response may be deemed waived.” Paper 8, 8. Thus, Patent Owner’s proposed construction for the limitation “no-switching criterion” is waived and we do not explicitly We do not discern a dispute between the parties regarding any limitation and we need not expressly construe any limitation to resolve the controversy before us. See, e.g., Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“We have reviewed Petitioner’s arguments, the supporting testimony provided by Dr. Durand, the cited portions of Golan, Martin, and Togo and the other cited evidence and we are persuaded that the proposed combination teaches the limitations recited in independent claim 1 as set forth above. Petitioner’s rationales for combining Golan and Martin and Golan, Martin, and Togo are set forth earlier in this Section, and is determined to be supported by sufficient rational underpinning for at least the reasons set forth above. Patent Owner’s contentions regarding secondary considerations of non-obviousness are set forth above and, as discussed, do not weigh in favor of non-obviousness because Patent Owner has not established a nexus between the claimed invention and the cited evidence. For the foregoing reasons, we conclude Petitioner establishes unpatentability of independent claim 1 over Golan and Martin by a preponderance of the evidence. Accordingly, we are persuaded that Petitioner demonstrates the unpatentability of claim 1 over the combination of Golan, Martin, and Togo by a preponderance of the evidence.” slip op. at 55
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“We do not agree with Patent Owner’s arguments, which are premised on a “physical” or “bodily” incorporation of limitations of one reference into the other. This is not the standard. See In re Sneed, 710 F.2d 1544, 1550 (Fed. Cir. 1983) (“[I]t is not necessary that the inventions of the references be physically combinable to render obvious the invention under review.”). The relevant inquiry is whether the claimed subject matter would have been obvious to those of ordinary skill in the art in light of the combined teachings of those references. See In re Keller, 642 F.2d 413, 425 (CCPA 1981). “Combining the teachings of references does not involve an ability to combine their specific structures.” In re Nievelt, 482 F.2d 965, 968 (CCPA 1973). Rather than express obviousness as the physical incorporation of a structure from one reference into the structure of another reference, the prior art should be viewed as a combination of teachings from different sources, and the use of those teachings by one of ordinary skill in the art. See KSR Int’l Co., 550 U.S. at 418(the conclusion of obviousness can be based on the interrelated teachings of multiple patents, the effects of demands known to the design community or present in the marketplace, and the background knowledge possessed by a person having ordinary skill in the art). Petitioner contends “Togo’s image-quality-based no-switching criterion teachings apply to the combination regardless of whether a distance between cameras is close or whether optical axes are parallel.” Pet. Reply 10 (citing Ex. 1040 ¶ 52). Petitioner seeks only “to incorporate Togo’s teachings of a no-switching criterion based on a specific ‘setting magnification X’ and ‘photography distance Y’ of an object to be imaged.” Pet. 32 (citing Ex. 1005 ¶ 15; Ex. 1010 ¶¶ 2, 37, 49; Ex. 1003 ¶ 68). Thus, Patent Owner’s argument does not undermine Petitioners showing For the foregoing reasons, we are persuaded that Petitioner’s rationale for combining Golan, Martin, and Togo is supported by sufficient rational underpinning. See KSR, 550 U.S. at 418. We are further persuaded that the cited evidence sufficiently supports Dr. Durand’s testimony.” slip op. at 43
