      “Absent a recitation of order, or an order mandated by grammar or logic, the steps of a method claim are not construed to require a particular order. See, e.g., Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed. Cir. 2003). Patent Owner argues that the steps of claim 1, a method claim, must be performed in sequential order. PO Resp. 13–16. Without commenting on or conceding Patent Owner’s proposal, Petitioner contends that “the trial grounds meet this proposed construction.” Pet. Reply 24–25; Tr. 8:25–11:16. Our record does not reflect any indication that Patent Owner’s proposed construction requiring the sequential ordering of the method steps is not at least encompassed by the correct construction of claim 1. Because of this, and because Petitioner agrees that the arguments in the Petition meet this construction, we accept Patent Owner’s construction as correct for the purposes of this Decision.” slip op. at 10

      “We do not agree with Patent Owner that Petitioner’s showing uses the same sound data to teach the “first sound data” of limitation 1.a and the “second sound data” of limitation 1.c. Patent Owner is correct that Rosenberg’s claim 5 describes the determination of a volume threshold based on the volume of the ambient audio signal in which characteristic form(s) (e.g., the name of the user of the media player) are present. Ex. 1006, 13:66–21, 14:28–30. However, the Petition describes using Fu’s “predetermined threshold” in combination with Hart-787’s device, which attenuates audio output of a device upon detecting a user’s utterance intended to gain the attention of the device, in order to “include adjusting the audio output volume of a wirelessly-linked audio-producing device when the voice-controlled device determines that the ambient noise level at the time a Ex. 1004, 2:22–37, 5:61–6:10, 9:18–25; Ex. 1005 ¶¶ 24, 32, 54; Ex. 1003 ¶¶ 88–89). Petitioner further proposes including a threshold that is advantageously based on the environment in which the device is operating as described in Fu, for example to respond to differing levels of noise at different times of day. Id. at 26, 29–30, 40 (citing Ex. 1006, 10:42–67, 14:28–30; Ex. 1003 ¶¶ 48–53, 55, 58, 87, 91, 107–109). We agree with Petitioner that Patent Owner’s arguments address the references individually instead of addressing the combination of the teachings proposed in the Petition. See Pet. Reply 8, 13–14; see also Dec. on Inst. 21–22, 23–24, 25–26. The Petition relies upon a combination of elements of Hart-787 with the predetermined threshold as taught in Fu and with establishing such a threshold based on the operating environment of a device as in Rosenberg. Pet. 26–31, 34–41. Patent Owner is correct that Rosenberg’s threshold is set at the time of the utterance in Rosenberg’s claim 5 and cites Petitioner’s declarant as “conceding” issues regarding how “Rosenberg’s volume threshold is determined.” PO Resp. 20–21. But this argument and the ostensible concession do not squarely address the proposed combination, which combines Fu’s teaching of an adjustment unit that “compares the volume of the ambient noise received . . . to a predetermined threshold” with Rosenberg’s teaching that such “a threshold may be ‘determined based on the volume of [an] ambient audio signal.’” Pet. 39, 40 (emphasis omitted) (quoting Ex. 1006, 14:28–30). While Patent Owner argues that “Petitioner has not proposed using a predetermined/pre-set threshold or a previously established threshold based on environmental noise in the combination of Hart-787 with F[u] and Rosenberg” (PO Resp. 46), we find, on the contrary, that the Petition describes a combination based predetermined threshold” and on a threshold “determined according to an environmental noise level.” Pet. 29–30. Thus, we find Petitioner’s unpatentability grounds do not suffer from the issues Patent Owner argues are a consequence of the purported use of the same sound data for the “first sound data” of claim limitation 1.a and for the “second sound data” of claim limitation 1.c. We do not agree with Patent Owner’s arguments regarding Fu’s teachings with respect to limitation 1.e’s “transition from a first state having a first volume level to a second state having a second volume level that is less than the first volume level” because these arguments similarly do not address the proposed combination. See PO Resp. 26–30. The Petition cites Hart-787 for attenuating the volume of an audio-producing device when a wake word is issued. Pet. 32–34, 43–44. The Petition cites Fu for adjusting volume of an audio-producing device if the level of ambient noise exceeds a predetermined threshold. Id. at 36–39, 44–45. Thus, even if Fu teaches only increasing the volume of an audio-producing device if the predetermined threshold is exceeded, the Petition relies on the combination of teachings of Hart-787 and Fu, and Patent Owner’s argument that neither reference teaches “decreasing a controllable appliance’s volume output when a previously established volume threshold is exceeded” (PO Resp. 30) does not address the combination proposed. Patent Owner’s argument that “Petitioner has not proposed modifying Fu to decrease a controllable appliance’s volume output when a volume threshold is exceeded” (PO Resp. 30) similarly does not address the combination proposed in the Petition. We also find that the preponderance of the evidence supports Petitioner’s showing regarding the motivation to combine the references.” slip op. at 23

See Pet. 23 (citing Ex. 1004, 5:47–51; Ex. 1003 ¶ 82), 43–44 (citing Ex. 1004, 1:67–2:7, 2:26–27, 5:47–51; Ex. 1003 ¶ 118). In addition, Petitioner shows that these control signals were well-known in the art and would have been known to one of ordinary skill in the art at the time of the invention, supporting its showing with additional testimony from its declarant. Id. at 44 (citing Ex. 10183, 2:39–47, 5:35–38; Ex. 10194 ¶¶ 3, 13; Ex. 1003 ¶¶ 44–45, 118). We conclude Petitioner’s evidence regarding the showing in Hart-787 is sufficient with respect to this point. Hart-787 describes altering a signal sent to the speaker to attenuate the audio from that speaker. Ex. 1004, 1:67– 2:1. Petitioner’s declarant testifies that using transmitted control signals to do this would have been known to one of ordinary skill. Ex. 1003 ¶¶ 44–45, 82, 118. We consider Petitioner’s evidence regarding what one of ordinary skill in the art would have understood from Hart-787’s disclosure to be sufficient for the showing regarding the “causing one or more commands to be automatically issued to the controllable appliance to thereby cause” that appliance to transition to a lower volume level, as required in limitation 1.e.

      “For purposes of this Decision, we thus make a preliminary determination that collateral estoppel precludes Patent Owner from relitigating the issue of whether Kovatch teaches a ranking associated with web site addresses indicating the order in which to access a plurality of preselected web sites. In challenging independent claims 1 and 2 as unpatentable under 35 U.S.C. § 103(a) over Kovatch and Burrows, the Petition presents an element-by-element analysis to support its position. Pet. 14–32. That analysis relies on Kovatch’s disclosure of the HeyAnita system for accessing web sites to retrieve information a user requested, and relies on Burrows for disclosure of a system for ranking database records that are “presented to the users in a rank order where the pages having a higher rank are presented first.” Id. at 12–13 (citing Ex. 1006, 27:28–32, 32:14–47). Petitioner reasons that a person of ordinary skill in the art “would have found it obvious to apply Burrows’s numbered ranking and polling approach to Kovatch’s destination tree to better identify and present the records of the most interest to the user.” Id. at 13 (citing Ex. 1006, 3:56– 58). In particular, because Burrows explains that “there needs to be a way to rank order the list in a meaningful manner,” Petitioner reasons that a person of ordinary skill in the art “would have been motivated to apply Burrows’s numbered ranking to Kovatch’s destination tree web pages to provide those of interest first.” Id. (citing Ex. 1002 ¶ 115); Ex. 1006, 27:28–29. Petitioner’s element-by-element analysis explains Petitioner’s position as to how each limitation of independent claims 1 and 2 is met within such a combination. Id. at 14–32. Although Patent Owner makes a number of arguments in its Preliminary Response why the combination does not meet certain limitations, those arguments are precluded by our preliminary determination that collateral estoppel applies. See Prelim. Resp. 29–44.7 We have thus re-evaluated the parties’ arguments in light of the findings made in the 846 IPR, and affirmed by the Federal Circuit, and we conclude that Petitioner demonstrates a reasonable likelihood of prevailing on its challenge of independent claims 1 and 2 as unpatentable under 35 U.S.C. § 103(a) over Kovatch and Burrows. We accordingly grant Petitioner’s Rehearing Request and institute an inter partes review of all claims on all grounds asserted in the Petition.8 See SAS Inst. Inc. v. Iancu, 138 S. Ct. 1348, 1359–60 (2018); 37 C.F.R. § 42.108(a).” slip op. at 20

      “The party seeking to invoke collateral estoppel must show: “(1) the issue is identical to one decided in the first action; (2) the issue was actually litigated in the first action; (3) resolution of the issue was essential to a final judgment in the first action; and (4) [the party against who collateral estoppel is being asserted] had a full and fair opportunity to litigate the issue in the first action.” Google, 54 F.4th at 1381. Each of these requirements appears to be met with respect to the issue of whether Kovatch discloses rankings associated with the order in which web site addresses are accessed. First, the claim limitations at issue in the two proceedings are sufficiently similar to raise the issue of collateral estoppel. See Ohio Willow Wood, 735 F.3d at 1342 (“If the differences between the unadjudicated patent claims and adjudicated patent claims do not materially alter the question of invalidity, collateral estoppel applies. . . . Thus, the mere use of different words in these portions of the claims does not create a new issue of invalidity.”). For example, claim 1 of the ’705 patent recites “a rank number assigned to each one of said web sites and stored in said database” and “access[ing] one of said web sites having the highest said rank number,” while claim 10 of the ’431 patent recites “a ranking associated with each said web site address, said ranking indicating the order in which the plurality of pre-selected web sites are accessed.” Ex. 1001, 19:58–59, 19:65–66; 846 IPR, Ex. 1001, 21:9–11.” slip op. at 18

      “Although Patent Owner appears to argue that applying the preference factors to a general score does not encompass weighting the general score’s components (see, e.g., id. at 10–12; Sur-reply 13–16), this is not reflected in Patent Owner’s proposed construction (PO Resp. 12). Patent Owner’s construction provides no limitation on how the preference factors are applied to a general score. See id. To the extent Patent Owner argues that the phrase “applied to,” as recited in the claim, excludes such component-based weighting, we disagree. Rather, the record better aligns with Petitioner’s argument that “applied to” involves a linear combination of values, which could be the values of the general score’s components. See Pet. 30–31. Petitioner’s position is supported by the plain language of the claim, the ’727 patent’s discussion of weighted aggregation, and Mr. William’s testimony—all of which indicate that weighting the component scores is encompassed by claim 1. As for the plain language, the claim does not define how the factors are “applied to” the general score. Rather, the claim only recites that they are. In the context of the claim, the preference factors are applied to the general score. Patent Owner does not dispute this. PO Resp. 12. Claim 1 further recites that the customized score is based on the application of the preference factors to the general score. Ex. 1001, 23:14–27. We note that the generate the combined ranking, which is then used for the recited selection.

This is not case where an expert “does not disclose the underlying facts or data on which the opinion is based.” See 37 C.F.R. § 42.65(a). Rather, Mr. Williams adequately supports his testimony about the second preference factor with reasoning based on Jackson’s teachings about how the social-network distance is used to weight the global score.

Ex. 1006, 17:47–55, cited in Williams Decl. ¶ 147; see also Pet. 42–43; Reply 9. Mr. Williams also cites Jackson’s discussion of how social-network distance and geographic distance can be used together. Williams Decl. ¶ 147 (citing Ex. 1006, 3:57–4:22). We agree with Petitioner that Jackson adequately supports this part of Mr. Williams’s analysis. Reply 7–9. Specifically, Jackson discloses that a determination may use social-network distance to “modify the criteria” that it uses to provide posts to users. Ex. 1006, 3:66–4:1, cited in Williams Decl. ¶ 147. Jackson further explains how geographic distance can be used in addition to other criteria: “Transmitting the post to the second computing device may be dependent upon determining that the criteria is met and determining that the posting location is within the threshold distance.” Id. at 4:19–22 (emphasis added), cited in Williams Decl. ¶ 147. This is consistent with Jackson’s teaching that a post may be recommended based on several factors and for several reasons. Id. at 17:47–67, cited in Williams Decl. ¶ 147. Also, Jackson explains how the global score, which Petitioner mapped to the recited “general score,” is used to generate a post’s score: “[A] particular post’s global score . . . is multiplied by, divided by, or summed with a distance between” a user and the post’s author. Id. at 9:54–67, cited in Williams Decl. ¶ 148. Jackson weights a post’s global score against a position of the posts author in a social graph. Id. at 9:25–53. Mr. Williams testifies that it is obvious and conventional to generate the modified scores embodiment. Williams Decl. ¶ 144. This is supported by Jackson. In another example cited by Petitioner, Jackson multiplies a post’s global score by a geographic distance to generate a personal score. Id. at 21:60–22:5, cited in Pet. 37, 39, 43.

      “Weighing the parties’ arguments and evidence, we find that Petitioner demonstrates by a preponderance of the evidence that a person of ordinary skill in the art would have been motivated to combine the teachings of Ji and Sarafa. As explained below, Petitioner persuades us that a person of ordinary skill in the art would have understood that Ji teaches automatic scrolling, and that Sarafa’s automatic scrolling would have beneficially complemented Ji’s. Pet. 21–22; Pet. Reply 14–17; Ex. 1003 ¶¶ 75–77; Ex. 1018 ¶ 47. Additionally, regardless of whether Ji teaches automatic scrolling in paragraph 92, Petitioner persuades us that Ji and Sarafa address similar problems related to tracking and understanding convoluted conversations in messaging systems. See Pet. 16–21; Ex. 1003 ¶¶ 64, 65, 70, 73, 74. As Dr. Cockburn testifies, Ji emphasizes the problem that users cannot quickly find and understand messages in complicated message streams. Ex. 1003 ¶ 64 (citing Ex. 1006 ¶ 2); Pet. 16. Petitioner also persuades us that Sarafa addresses such problems, at least in part, by expressly teaching certain advantages of its scroll-back feature, such that a person of ordinary skill in the art would have considered it advantageous to add Sarafa’s scroll-back feature to Ji’s system. See Pet. 18–19; 21–23; Ex. 1003 ¶¶ 70, 74. For example, addressing the same problems discussed in Ji, Sarafa explains that its scroll back feature would facilitate a user’s ability to understand a complicated conversation because “[m]aking available the context of a quoted message may benefit a user in understanding a quoted message by providing messages that were displayed before and/or after the quoted message so as to play the quoted message in context.” Ex. 1007 ¶ 90; Pet. 19; Ex. 1003 ¶ 70. Similarly, Sarafa explains that its scroll back feature “provid[es] additional context to users . . . , improving the user experience of quoted messages for its users.” Ex. 1007 ¶ 23; Pet. 19; Ex. 1003 ¶ 70. We find that these disclosed benefits would have provided compelling motivation for a person of ordinary skill in the art to add Sarafa’s scroll back feature to Ji’s messaging system. Pet. 19–23; Ex. 1003 ¶¶ 71, 73–77. Indeed, as Dr. Cockburn explains, “[s]ince Ji also quotes the original message in the reply, Sarafa would therefore be a natural complement to Ji.” Ex. 1003 ¶ 77.” slip op. at 42

Petitioner clarifies that the Petition identifies Exhibit 1009’s buy page as corresponding to the “composite web page contain[ing] one or more selectable URLs” recited in the claim and identifies the “view cart,” “modify cart,” and “check out” pages linked to the “buy” page as corresponding to the recited “hierarchical set of additional pages.” See Req.

Petitioner thus demonstrates that the buy page shown in Exhibit 1009, i.e., the recited “composite web page,” contains one or more selectable URLs connecting the “view cart,” “modify cart,” and “check out” pages to the buy page, i.e., the recited “hierarchical set of additional web pages,” as required by the claim.

PO Resp. 15–16. Patent Owner contends the claim language and the specification describe the actual delivery of information to the local bulletin board. Id. (citing Ex. 1001, 6:27–31, 12:33–35). Petitioner contends Patent Owner’s proposed meaning is unreasonably narrow and proposes, instead, that the term “should be construed as ‘making the information available to another process,’ consistent with its plain meaning.” Reply 7 (citing Ex. 1036 ¶ 29). Petitioner observes the challenged claims do not recite delivery into a second process, and 7 Petitioner refers to the ’843 patent; in context, it is clear the reference is intended to be to the ’705 patent. additionally notes claim 1 of the related ’843 patent merely requires “sharing the information” and it is not until dependent claim 16 of the ’843 patent that “sharing” further includes “providing the information.” Id.
