    “Beel actually discloses the following: [0321] On the peripheral device 32 the video packets are received at the corresponding plug and play port, e.g. the USB port 11, read by the Human Interface Driver (HID) interface handler 13, unpacked to remove HID protocol headers in an unpacker 20 and then transmitted to the communications network by a transmitter 21. The network can be wireless for example WiFi or LiFi network.

  RulingsFinal written decision

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

    “Behbahani teaches “comparing the strength of the desired signal to the strength of the interfere signal,” as recited in limitation 1(a). See PO Resp. 68–69; Sur-reply 21–23. Although Petitioner argues that Behbahani “expressly teaches comparing the desired and interferer signal strengths,” Petitioner does not cite to sufficient evidence in support of this statement. Pet. 38. The basis of Petitioner’s argument is that Behbahani teaches the same process for determining signal strengths as shown in Figure 4 of the ’202 patent. Figure 4 of the ’202 patent is reproduced below: Figure 4 shows, among other things, signal strength indicator circuits 440 and 450 connected to input line 410 and output line 460, on either side of gain element 420 and filter 430. Ex. 1001, 6:53–57. The input signal on input line 410 is shown as desired signal 412 and interferers 464 and 466. Id. at 59–61. Figure 4 is further described as follows. The signal strength indicators 440 and 450 do not provide information as to the relative sizes of the desired and interfering signals. Rather, a cumulative signal level is provided at their outputs. For example, the first signal strength indicator 440 outputs a level corresponding to the sum of desired signal 412 and interfering signals 414 and 416, while the second signal strength indicator 450 provides a signal level corresponding to the sum of desired signal 462 and interfering signals 464 and 466. In this specific example, the gain of the gain and filter circuit combinations is shown as approximately one, while the interfering signals 414 and 416 signal levels are reduced. A comparison of the signal levels provided by the signal strength indicators 440 and 450 indicates that much of the combined received signal on line 410 has been filtered. Accordingly, it may be deduced that large interfering signals present at the input are being filtered by the filter 430. From this information, as will be shown in greater detail below, the bias, impedance, and gain of the gain stage 420 and filter 430 combination may be optimized to reduce power dissipation. Ex. 1001, 6:61–7:13 (emphasis added). In other words, Figure 4 shows a comparison of a sum of the desired and interferer signals output from the strength indicator circuits, not a comparison of the strength of the desired signal and the strength of the interferer signal, as required by the claim language. See Sur-reply 22–23. The ’202 patent describes Figure 4 as “an embodiment,” and claims are not limited to specific embodiments described in the specification. See Phillips v. AWH Corp., 415 F.3d 1303, 1323 (Fed. Cir. 2005) (en banc). Petitioner even admits that Figure 4 “compar[es] a cumulative signal strength at a first node to a cumulative signal strength at a second node.” Pet. 36 (emphasis added).

    “Pursuant to 37 C.F.R. § 42.23(b), a reply “may only respond to arguments raised in the corresponding . . . patent owner response.” We agree with Petitioner, for the reasons stated in the Opposition, that the arguments in the Reply and Reply declaration testimony are responsive to arguments raised in the Patent Owner Response. See Opp Mot. 7–12 (explaining the positions taken in the Petition, Patent Owner’s arguments in Response, and the arguments presented in Reply); see Corephotonics, Ltd. v. Apple Inc., 84 F.4th 990, 1008–1009 (Fed. Cir. 2023). Petitioner does not provide a new theory of unpatentability; rather, Petitioner responds and elaborates on the theory presented in the Petition to explain why Patent Owner’s arguments are incorrect. E.g., Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d 919, 925 (Fed. Cir. 2019) (“Parties are not barred from elaborating on their arguments on issues previously raised.”); Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1081–82 (Fed. Cir. 2015) (reasoning that rebuttal evidence should be responsive such that it is offered “to explain, repel, counteract, or disprove the evidence of the adverse party”). “[T]he introduction of new evidence in the course of the trial is to be expected in [IPR] trial proceedings” and permissible “as long as the opposing party is given notice of the evidence and an opportunity to respond to it.” Genzyme Therapeutic Prods. Ltd. P’ship v. Biomarin Pharm. Inc., 825 F.3d 1360, 1366 (Fed. Cir. 2016). We also note that our Consolidated Trial Practice Guide (“CTPG”) states that In most cases, the Board is capable of identifying new issues or belatedly presented evidence when weighing the evidence at the close of trial, and disregarding any new issues or belatedly presented evidence that exceeds the proper scope of reply or sur-reply. As such, striking the entirety or a portion of a party's brief is an exceptional remedy that the Board expects will be granted rarely. CTPG at 80, 84 Fed. Reg. 64,280 (Nov. 21, 2019). We follow that guidance here. Further, Patent Owner argues that Dr. Abidi’s testimony as a co- author of Behbahani is “self-serving and unsupported.” Mot. 6–7. The fact that Dr. Abidi is a co-author of Behbahani, as well as Petitioner’s expert, is not, in and of itself, sufficient to discredit Dr. Abidi’s testimony. The CTPG provides that “[t]he Board has broad discretion to assign weight to be accorded expert testimony.” CTPG 35. We are capable of discerning from the testimony and the evidence presented whether Dr. Abidi’s testimony should be entitled to any weight, either as a whole or with regard to specific issues. We will weigh the testimony on an issue-by-issue basis as appropriate. Moreover, to the extent that Patent Owner has pointed out the inadequacies of Dr. Abidi’s testimony, we are also capable of noting those inadequacies and weighing that testimony accordingly. For the foregoing reasons, Patent Owner’s motion to strike is denied.” slip op. at 11

    “We also disagree with Petitioner that “Dr. Abidi provided well- reasoned analysis that Behbahani teaches determining and comparing desired and interferer signal strengths.” Reply 27 (citing Ex. 1003 ¶¶ 179– 181). We have reviewed the Dr. Abidi’s testimony cited in the Petition and Reply for limitation 1(a) (Ex. 1003 ¶¶ 95, 96, 113–120, 179–181; Ex. 1042 ¶¶ 12–16), and we disagree that Dr. Abidi provided well-reasoned analysis that Behbahani teaches comparing desired signal strengths with interferer signal strengths. Rather, Dr. Abidi’s testimony focuses on determining or measuring desired and interferer signal strengths, generally simply repeats what is in the Petition, and only provides a conclusory assertion that Behbahani expressly teaches comparing the strengths of the desired and interferer signals without providing any explanation. See TQ Delta, LLC v. Cisco Sys., Inc., 942 F.3d 1352, 1358–59 (Fed. Cir. 2019) (“Conclusory expert testimony does not qualify as substantial evidence.”). Accordingly, Dr. Abidi’s supporting testimony is also deficient. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). As Patent Owner points out, the only comparison mentioned by Petitioner in Behbahani is to derive the strength of the interferer signal. Sur-reply 22 (citing Pet. 38–39); Ex. 1004, 1207 (“[B]y comparing the signal level at the input and the output of the digital filter (DI and DO), the relative strength of the out-of-channel signal that passes through the analog filter is calculated”).

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

    “After review of the ’404 patent’s description, we find no disclosure that pressing the panic button together with another button causes the panic button to ready itself to perform functions (1) and (2) as recited in limitation 1[d]. The closest descriptions we find to limitation 1[d] are that the safety switch readies the panic button to contact 911 (Ex. 1001, 6:59–62), that the panic button may be activated by pressing the panic button with another button (id., 3:59–67, and that the panic button may start a speech recognition process that can trigger the device (id., 7:61–62). Consequently, claim 1 is itself the best source for determining what the claim language means. We determine that the ordinary and customary meaning of the “ready itself” feature of claim 1 is that the panic button “prepares itself to be triggered to perform the panic button functions (1) and (2).” Since the intrinsic evidence is sufficiently clear to discern the meaning of the “ready itself” limitation, we do not resort to extrinsic evidence. See Phillips, 415 F.3d at 1317 (explaining that extrinsic evidence is less significant than intrinsic evidence); Seabed Geosolutions (US) Inc. v. Magseis FF LLC, 8 F.4th 1285, 1287 (Fed.

  • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportDecided for petitioner

    “Thus, the ’353 application describes that moving the safety switch into position readies the panic button to contact 911, which is not the same as the panic button being activated to ready itself to perform functions (1) and (2) required by claim 1 of the ’404 patent. Patent Owner’s reliance on disclosures elsewhere in the ’353 application is unavailing. PO Resp. 5–8 (citing Ex. 1006, 15, 17, 19–21, 23, 25); PO Sur-Reply 2–3 (citing Ex. 1006, 15, 17, 19–20, 24–25)). For example, while the ’353 application does mention voice activation with a codeword and activation by depressing of the panic button together with another button (see, e.g., Ex. 1006, 17, 21, 24–25), it does not mention that depressing the panic button together with another button causes the panic button to ready itself to perform recited functions (1) and (2). The application explains that “[t]he [panic] button can send a signal to a controller inside the device to activate [the code word activation] process” and “[t]he [panic] button can start the speech recognition process in one embodiment, to trigger the device.” Ex. 1006, 25. But that describes readying the device for activation by the code word, not readying the button to perform the recited functions. The ’353 application also mentions the word “ready” in relation to using a self-defense mechanism such as pepper spray, which does not appear to be related the readying of the panic button recited in claim 1. Ex. 1006, 15, 19–20. Petitioner has thus met its burden to demonstrate that claims 1–8 of the ’404 patent lack written description support for a panic button adapted to “ready itself” to perform the recited functions because the limitation is not present in the ’353 application to which the ’404 patent claims priority.3 Pet. 8–10. The burden of production thus shifted to Patent Owner to demonstrate that the ’353 application has written description support for limitation 1[d], which it has not done on this record.

    “DiPerna964 discloses a separate “safety” switch that readies the panic button to contact 911 upon being pressed (Ex. 1028 ¶ 41), but there is no mention of pressing the panic button together with another button to cause the panic button to “ready itself” to perform panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit, as limitations 1[d] and 1[e] require. DiPerna964 mentions pressing two buttons together to activate the panic button (see, e.g., Ex. 1028 ¶¶ 17, 23–25, 27), but not to “ready itself” to perform recited functions (1) and (2). Petitioner relies on Strack’s triggering the collection of audio, video, and location data for transmission to a remote location as equivalent to a panic button readying itself to, when activated, perform the panic button functions (1) dialing a public or private network for an emergency purpose and (2) activating the transmitting unit. Pet. 15–17 (citing Ex. 1002 ¶¶ 76–88). We do not agree with Petitioner’s contention because Petitioner fails to explain how Strack’s button press that collects and then transmits audio, video, and location data would ready the panic button to perform recited functions (1) and (2). It appears that Strack’s button press readies the device, not the button, to perform the functions. As neither DiPerna964 nor Strack nor their combination teach or suggest limitations 1[d] and 1[e], we determine it is unnecessary to proceed further with the obviousness analysis. PAR Pharm., Inc. v.

Petitioner must explain with particularity how the prior art would have rendered the Challenged Claims unpatentable. 35 U.S.C. § 312(a)(3); 37 C.F.R. § 42.104(b)(4) (“The petition must specify where each element of the claim is found in the prior art patents or printed publications relied upon.”). IV. PATENTABILITY ANALYSIS A. Legal Standards A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the subject matter sought to be patented 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 (2007). The obviousness inquiry requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)).

    “From this description in Burrows, it is clear that index 70 has no sense of ranking, and that Burrows’ system overall has no sense of ranking prior to a query; thus, adding or deleting a webpage from the index does not change a ranking that does not yet exist. It is also clear that, if a page is flagged as deleted, it will be ignored by the query module when the query module queries the index and ranks the identified qualified pages. Id. at 15:12–16, 15:21–22. The webpage’s rank is not decreased, as the webpage is never ranked in the first place. As Mr. Occhiogrosso testifies: web page. A “polled web site” page cannot be ranked in the Burrows system because the Burrows ranking is performed only after a user query is performed. Only at that time can the Burrows system provide a ranked list (of qualified webpages) for presentation to the user. As Burrows discloses, the Automated Web Browser is robotic in nature and not associated with the queries of users. Ex. 2009 ¶ 181. Mr. Occhiogrosso’s testimony on this point is consistent with Burrows’ description, credible, and entitled to substantial weight. We have considered Mr. Lipoff’s testimony that a skilled artisan “would have understood that combining Burrows’s polling mechanism receiving no response into Kovatch would decrease the entries’ ranking or placement in Kovatch’s destination tree in order to further limit the pages that may not be of interest to the user.” Ex. 1002 ¶ 172 (citing Ex. 1006, 1:38–46). That testimony, however, is conclusory and lacks persuasive reasoning. Moreover, the passage in Burrows to which it cites (Ex. 1006, 1:38–46) does not teach or suggest decreasing the ranking of webpages. Thus, Mr. Lipoff’s testimony on this point lacks credibility and is entitled to little weight.

Mr. Lipoff repeats this statement in his testimony without identifying the basis for it, rendering that testimony of little value. Ex. 1061 ¶ 24. In any case, it appears that Petitioner and Mr. Lippoff are arguing that a general notion of processing cost any time computer processing occurs would lead a skilled artisan to decrease a webpage’s rank based on response time. This is a new argument, not presented in the Petition, and is therefore forfeited and will not be considered.
