“This argument is unpersuasive because Buruganahalli uses rules/policies to filter encrypted packets by correlating them with handshaking packets that have unencrypted data, in the same way that is done in the ‘856 Patent. The only “filtering step” in the patent that “use[s] rules to filter encrypted packets without decryption” (PO Resp. 20) is the hello message approach used, for example, at steps 19 and 23 (see id.), which is clearly disclosed in Buruganahalli.7 As explained above, the ‘856 Patent does not describe applying rules to encrypted packets. Instead, it describes (a) filtering encrypted packets by correlating them with unencrypted data in other packets and (b) by decrypting the packets and applying the rules that are recited in the claims to unencrypted data. As also explained above, the amendment added the rules of step 22, which are applied to decrypted data, to a claim that was drafted to cover filtering of encrypted packets. However, among the criteria used in the filtering performed at step 22 is a “uniform resource identifier (URI),” which, we conclude, covers Buruganahalli’s “domain name.” Thus, despite the error made during prosecution, the claims that issued cover Buruganahalli’s method of determining that a session should be filtered based on a domain name in unencrypted handshake data.” slip op. at 28

“given to the Eastern District of Virginia court’s opinion because it was later vacated. The district court considered all of the Read factors (applying Read Corp. v. Portec, Inc., 970 F.2d 816, 826-827 (Fed. Cir. 1992)), of which only the first factor is directed to deliberate copying, although factors 2 and 9 bear indirectly on the issue of copying. The district court determined that “[t]he fact that Cisco released products with Centripetal’s functionality within a year of these meetings goes beyond mere coincidence. Therefore, the fact that Cisco’s system mirrors the functionality of the Centripetal patents is compelling evidence that damages should be enhanced for copying.” Ex. 1027, 157. Without more, it is difficult to evaluate the processes that the district court employed to reach its determination. As the Federal Circuit instructed, we need “not [] go searching throughout the entire litigation record to find the evidence of copying, but [we have] an obligation to consider the specific evidence that was put before” us. Centripetal Networks, 19. We continue to determine that the vacated finding of the district court should be provided little weight, especially in view of the strong case of obviousness discussed above. Examination of Aaron Striegel We also do not find the Aaron Striegel’s testimony to be particularly persuasive. The testimony provides statements such as “I found evidence that it could be plausible,” “[s]o we can see the timeline is very plausible,” and “I found it very plausible that indeed that this technology could have made its way into these respective accused products.” Ex. 1029, 31:12–32:3. This testimony suggests the possibility of copying but does not demonstrate actual evidence of copying. At most, this testimony indicates that further consideration of the underlying evidence is warranted, but does little to support an ultimate finding of copying. Again, even taking this testimony as evidence of copying, it still must stand up against the strong case of obviousness discussed above.” slip op. at 40

“The District Court did not provide an element-by-element analysis of how the claims of the ‘856 Patent cover this description. See Ex. 1027, 41. However, from the description, we understand the Court to have concluded that the system receives rules, identifies a set of packets as part of a flow using the NetFlow logs, “determines” that encrypted packets in the flow match known malicious signatures based on unencrypted data in other packets (e.g., data in the SNI), and then filters the flow based in a URI (e.g., that from the SNI), routing it to the null interface. The Court does not describe how the system “determines” that encrypted packets match known malicious signatures based on information in unencrypted packets, but we assume that is done as in the ‘856 Patent, by correlation, i.e., an encrypted packet is “determined” to match a threat indicator if it is in the same flow as a packet with unencrypted information that matches the threat indicator.10 With that understanding, we conclude that the allegedly infringing system operates, as least at the level described in the court’s decision, in the same way Buruganahalli’s system operates, filtering encrypted packets due to their presence in a flow that includes packets with unencrypted data, such as in a handshaking packet. It follows that Patent Owner is unable to establish a nexus, because “[w]here the offered secondary consideration actually results from something other than what is both claimed and novel in the claim, there is no nexus to the merits of the claimed invention.” Novartis AG v.

But beyond that, it appears that the problem identified as “unsolvable” in the press release––“detect[ing] known attack signatures even in encrypted traffic”––had, in fact, already been solved in Buruganahalli, using the very same hello message, flow correlation, and man-in-the-middle techniques described in the ‘856 Patent. We thus cannot say that the press release identifies a long-felt need that was actually unsolved. See ZUP, 896 F.3d at 1374 (explaining that “[w]here the differences between the prior art and the claimed invention are . . . minimal . . . it cannot be said that any long-felt need was unsolved”) (quoting Geo.

“operatively linked to said electronic circuit” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. We note there is no presumption of applying means-plus-function analysis to the switching element, because the limitation does not use the words “means for” that would mandate such claim construction treatment, and “switching” may invoke structure as well as function. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349–1350 (Fed. Cir. 2015) (en banc) (holding that “use of the word ‘means’ creates a presumption that § 112, ¶ 6 applies”). Regardless, we look to the meaning of the claim phrase at issue in view of the specification. We determine that the ’294 patent provides a clear, concise meaning for the switching element upon which both parties rely for construction. Patent Owner’s express agreement with Petitioner, that the claimed switching element is described in the ’294 patent as “any type of device allowing data to be conveyed according to alternate data conveyance operations in response to an activation cue being received by transceiver 18 or not,’” is particularly telling because it is not consistent with Patent Owner’s argument that the switching element means “switching of the data.” Resp. 7, 31 (citing Ex. 1001, 9:28–318). The claim language does not recite, and the specification does not describe, the switching element as a device that switches the data.

Pet. 7–8 (citing Ex. 1001, 2:14–17, 4:7–14, 9:3–6; Ex. 1003 ¶¶ 67–68). As above, whether we construe the “[external] data exchange device” under 35 U.S.C. Section 112, sixth paragraph or not, the result is the same. Patent Owner, quoting the description of a data exchange device in the ’294 patent, contends that a “[external] data exchange device” “can be any sort of data exchange device comprising an electronic circuit (not shown) therein and a data transceiver 9a.” Resp. 8 (quoting Ex. 1001, 9:4–6). Patent Owner also responds to the Petition by clarifying that “[a]n external data exchange device is not a transceiver but a device with a transceiver.” Id. (citing Ex. 2001 ¶ 48). Petitioner argues in reply that Patent Owner does not contest Petitioner’s mappings of Mooney’s “cordless telephone base unit” or “cellular network infrastructure” to the claimed data exchange devices, such that no construction is necessary to resolve the dispute. Reply 5 (citing Resp. 16–37; Wellman, Inc. v. Eastman Chem. Co., 642 F.3d 1355, 1361 (Fed. Cir. 2011)). Limitations [1.c] and [1.d] recite “a first [second] data transceiver operatively linked to said electronic circuit [in the cell phone],” both of which are defined functionally as “for exchanging data between said electronic circuit [in the cell phone] and a first [second] external data exchange device over a first [second] communication link.” Nothing in the the other independent claims, further limits the form or function of the “[external] data exchange device,” although a device external to the cell phone may invoke additional structure.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“Thomason are in the same field of endeavor. Thomason describes a camera and method for correctly orientating pictures from the camera. See, e.g., Ex. 1004 ¶¶ 1, 2 29–40, Figs. 3a–3b. In particular, Thomason is interested in rotating and cropping images to reduce the effect of poor orientation. Pet. 9 (citing Ex. 1004 ¶¶ 2, 34, 36). Pacurariu likewise describes aligning and resizing/cropping of a captured image to correct poor orientation. See, e.g., Ex. 1005 ¶¶ 1, 3, 45–56, Figs. 5A–5C. The preponderance of the evidence also supports that a person having ordinary skill in the art would have had reason to combine the Pacurariu’s teachings with Thomason to predictably improve Thomason. Thomason teaches correct rotation of video data and makes use of rotation sensor to correct rotated images. Pet. 19–21 (citing, e.g., Ex. 1004 ¶¶ 4, 27, 29, 35; Ex. 1002 ¶¶ 76–77). Pacurariu similarly uses sensors and measures tilt angle of the camera. Id at 21–22 (citing, e.g., Ex. 1005 ¶¶ 51–52, Fig. 6; Ex. 1002 ¶ 78). Pacurariu further teaches that its tilt data angle can be stored for each “video frame.” Id. at 22 (citing Ex. 1005 ¶ 52). Petitioner, with support from credible testimony of Dr. Katsaggelos, explains how the teachings of Thomason and Pacurariu could be successfully combined. Id. at 23 (citing, for example, Ex. 1002 ¶ 81). A person of ordinary skill in the art could have known that Thomason’s system could be improved by saving rotation data for each video frame and correcting images on a frame-by-frame basis. Id. at 23–24. The testimony of Dr. Katsaggelos is credible in this regard. Ex. 1002 ¶¶ 80–81. Petitioner and Dr. Katsaggelos explain the references’ teachings and, based on these teachings, assert that a person having skill in the art would have had reason to combine with reasonable expectation of success based on those teachings. Reason to combine may properly come from the references themselves. KSR Int’l Co., 550 U.S. at 418 (explaining reason to combine may come from “interrelated teachings of multiple patents”). Based on the evidence presented, Petitioner establishes by a preponderance of the evidence that a person having ordinary skill in the art would have had reason to combine the teachings of Thomason and Pacurariu with a reasonable expectation of success. Ex. 1002 ¶¶ 76–81, 89–92; Ex. 1004 ¶¶ 4, 8–9, 27, 29, 35; Ex. 1005 ¶¶ 26, 41, 46, 51–52, 55–57, Figs. 6, 7.” slip op. at 27

“evaluating nexus between the claimed invention and objective evidence of nonobviousness, also referred to as secondary considerations. Lectrosonics, Inc. v. Zaxcom, Inc., IPR2018-01129, Paper 33 at 33 (PTAB Jan. 24, 2020) (precedential). We first consider whether Patent Owner has demonstrated “that its products are coextensive (or nearly coextensive) with the challenged claims,” resulting in a rebuttable presumption of nexus. Id. at 33. If not, that “does not end the inquiry into secondary considerations”; “the patent owner is still afforded an opportunity to prove nexus by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Id.

“II. ANALYSIS A. Institution of Inter Partes Review We instituted an inter partes review in the Apple IPR on all challenged claims and all asserted grounds of unpatentability. Apple IPR, Paper 10 (institution decision); see also Apple IPR, Paper 2 (the “Apple Petition”). Petitioner here challenges the same claims and asserts the same grounds of unpatentability as those on which we instituted the Apple IPR. Compare Pet. 2, with Apple Petition 1; see also Mot. 1 (asserting the instant “Petition is substantively identical to Apple Inc.’s petition (‘Apple Petition’) in the Apple IPR, including that it relies on the same expert declaration,” and asserting “the same grounds presented in the Apple IPR”). As indicated, Petitioner also relies on the same declarant as did the petition in the Apple IPR. Mot. 1; compare Ex. 1003 (Hannaford Declaration), with Apple IPR, Ex. 1003 (same). Because the grounds of unpatentability in the instant Petition are identical to those in the Apple IPR and for the same reasons stated in our Decision to Institute in the Apple IPR, we institute inter partes review in this proceeding on the grounds presented in the Petition. See Apple IPR, Paper 10 (analyzing challenges in the Apple Petition).” slip op. at 7
- PTAB / AIA Trials › Joinder §315(c) / SAS all-or-nothingJoinder, grantedGranted
“We determine that Petitioner has met its burden of showing that joinder is appropriate because, as set forth above, the Petition (1) is substantially identical to the Apple Petition, (2) contains the same grounds based on the same evidence, and (3) relies on the same declaration, the Hannaford Declaration (Ex. 1003). Mot. 1, 4. Petitioner represents that “joinder will not negatively impact the Apple IPR trial schedule” and “expressly consents to the existing trial schedule.” Id. at 10; see also id. at 7 (“Proceeding with a consolidated inter partes review would avoid potential inconsistency, promote efficient review of the same claims for the same patent under the same grounds, and would result in a final written decision without delay.”). Petitioner also represents that as “long as Apple remains in the joined IPR, Nintendo remains in a limited ‘silent understudy’ role that does not actively participate in the IPR.” Id. at 8. The record supports Petitioner. In addition, the final written decision in the Apple IPR is due to issue on or before October 15, 2025, with the Oral Hearing complete and no further briefing due. See IPR 2024-00807, Paper 15 (Oral Hearing Transcript); Paper 18, 2–3. Therefore, as Petitioner argues, joinder by Petitioner will have little or no impact on the trial schedule in the Apple IPR. On the other hand, if the Board denies joinder, Petitioner submits that it “intends to file a separate petition for IPR (‘Second Petition’) that includes grounds in addition to some (or all) of the grounds in the Apple IPR.” Mot. 14.” slip op. at 10
