    “B. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art (“POSITA”) at the critical time “would have had at least a bachelor’s degree in computer science, electrical engineering, or a related field, and at least two years of work or research experience in the field of content delivery management or networks,” and that “additional education could substitute for work experience.” Pet. 3 (citing Ex. 1008 ¶¶ 51–53).

    “We do not agree. The Petition states that Glines discloses that the anycast is resolved by an ISP DNS server. Pet. 20. The Petition identifies Glines’s local ISP DNS resolver 18 as the claimed ISP DNS server. Id. The Petitioner further asserts that Glines’s ISP DNS resolver 18 sends the request to the DNS server 38, but states that “Glines’s local DNS resolver, an ISP DNS server, thus causes the hostname . . . to be resolved.” Id. at 21–22. The Petition also drew an analogy with the ’112 patent and the role of local DNS server 70a in the Petition. See Pet. 20–21. Because the Petition and the Reply both identify Glines’s local ISP DNS resolver 18 as causing the hostname to be resolved, Petitioner has not advanced a new theory of unpatentability in its Reply. 6 At oral argument, Patent Owner suggested a narrower claim reading, but admitted that this had not been briefed.

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

    “We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”).” slip op. at 29

    “meaning of “icon” as claimed, including the dependent claims, the specification, the prosecution history, and the extrinsic evidence including expert testimony and dictionary definitions, we determine that the plain meaning of “icon” is readily apparent from the claims themselves. See Phillips, 415 F.3d at 1314 (“In some cases, the ordinary meaning of claim language as understood by a person of ordinary skill in the art may be readily apparent even to lay judges.”). We find that the plain meaning of “icon” as claimed encompasses at least “textual elements” because claim 20 recites “the icons comprise textual elements.” See id. (“Other claims of the patent in question, both asserted and unasserted, can also be valuable sources of enlightenment as to the meaning of a claim term.”). We highlight that the additional intrinsic evidence cited by the parties is consistent with the plain meaning. For example, Figures 1 and 2 of the specification show icons comprising textual elements. As another example, during prosecution of the ’058 patent, the Examiner found that the claimed icons were taught by textual hyperlinks. Ex. 1002, 586, 592. In order to overcome the Examiner’s rejection and obtain an allowance (id. at 641–50), applicant subsequently amended the claims to recite “specifically designed,” thus implicitly conceding to the Examiner’s interpretation of icon as encompassing textual hyperlinks. Id. at 625–640; see PO Resp. 43–44 (citing Ex. 1002, 626–27, 645–46) (acknowledging that the Examiner allowed the claims because applicant amended the claims to recite “specifically designed for containing a set of icons.”).” slip op. at 11

  • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalTerm construed petitioner constructionDecided for petitioner

    “Requiring an element to be "specifically designed" for another element narrows the claim because it requires more than the first element being merely capable of being used with the second element. The term "configured to" is generally construed narrowly to mean "made to" and "designed to" rather than broadly to require merely "capable of". See In re Giannelli, 739 F. 3d 1375, 1379-80 (Fed. Cir. 2014) (the phrase "configured to" requires more than "mere capability." Rather, that term is synonymous with "made to" and "designed to."). However, rather than use "configured to", in order to avoid any confusion as to the narrower scope of the claims as amended, Applicant herein directly and explicitly requires "designed to." In re Giannelli at 1379-80 (Fed. Cir. 2014) (reversing an obviousness rejection because (1) the claims were properly construed narrowly to mean "designed to" and not broadly to encompass merely "capable of", and (2) the USPTO had not explained the motivation for modifying the prior art to meet the "design to" requirement) See also MPEP 2111.04, citing to In re Giannelli, for the proposition that a claim can be narrowed to require that it be "designed and constructed to be used" in a specific manner (as a rowing machine in the case of In re Giannelli). Logan has not been specifically designed and constructed in the required manner, so it does not cure all deficiencies of the primary reference Iki (which lacks any tree menu structure). Logan describes only "remote web" pages 90, 95 that are merely pages retrieved from Web browsing and stored in a web computer 25. Iki as modified by Logan would result on in a tree menu structure wherein not all levels of the tree included the required selection pages specifically designed for containing the claimed set of icons.

    “We find insufficient support in the specification or prosecution history to narrow the term “haptic effect” to only one that has not been modified or combined with another haptic effect. The ’738 patent still refers to combined or modified haptic effects as a “haptic effect.” Ex. 1001, 11:35–38 (“a haptic effect may further be modified or combined with another haptic effect” and “the haptic effect can include one or more haptic effects”). We also find no support for importing into the construction of “haptic effect” the ’738 patent’s example in which a haptic effect can be “based on the proximity signal and the touch sensor signal.” That is already an explicit claim limitation. Id. at 14:19–20 (“generate a haptic output signal based at least in part on the first [proximity] and second [touch] sensor signals”). Including that limitation as part of the construction of “haptic effect” would render the limitation superfluous. See Apple, Inc. v. Ameranth, Inc., 842 F.3d 1229, 1237 (Fed. Cir. 2016) (“The Board was correct to not include in its construction of ‘menu’ features of menus that are expressly recited in the claims . . . . Construing a claim term to include features of that term already recited in the claims would make those expressly recited features redundant.”). We also disagree with Patent Owner that the ’738 patent’s references to haptic effects modified or combined with other haptic effects are unclaimed embodiments. The ’738 patent discloses that a proximity-based haptic effect may be combined with a touch-based haptic effect, such as when “a particular haptic effect associated with a particular control on a user interface element [is] further . . . modified or combined with another haptic effect based on the proximity sensor signal,” or when “the haptic effect [to be output by the processor] . . . include[s] a haptic effect meant to confirm ‘pushing’ on a virtual button.” Ex. 1001, 11:32–40. These examples are consistent with the claim language and we find no credible evidence in the record that these embodiments are intended to be excluded from the claimed invention. Thus, we agree with Petitioner that it would be incorrect to construe the term “haptic effect” to include the extraneous limitations Patent Owner proposes. We also agree with Petitioner that a person of ordinary skill in the art reading the ’738 patent disclosure would have understood that a combined or modified haptic effect is still a haptic effect.” slip op. at 11

Ex. 1008, Fig. 12 (items 705, 710, and 715). The summed signal 715 is the basis for generating what the user would perceive as a single haptic effect. See Ex. 1004 ¶ 210–212. This meets limitation 1F. We agree with Petitioner’s argument as to why there would have been a motivation to modify Pratt to include Ku’s teachings. Petitioner’s argument is not merely that Pratt was ready for improvement; Petitioner persuasively argues that a person of ordinary skill in the art would have had reason to add Ku’s method for confirming that the user has touched the intended icon to Pratt’s system. Both Pratt and Ku already disclose using both proximity and touch data in generating a haptic effect, and based on the evidence of record, we are of the view that combining the two teachings would not have been uniquely challenging or otherwise beyond the level of ordinary skill in the art.

    “We agree with Petitioner that “gm boosting” is the only gm enhancement referred to in the ’074 patent, that the ’074 patent uses the terms “gm enhanced” and “gm-boost” synonymously, and that Patent Owner has failed to point to any credible intrinsic evidence of this alleged distinction. Although, “[i]n the absence of any evidence to the contrary, we must presume that the use of . . . different terms in the claims connotes different meanings, CAE Screenplates Inc. v. Heinrich Fiedler GmbH, 224 F.3d 1308, 1317 (Fed. Cir. 2000), in this case there is evidence to the contrary. In particular, the ’074 patent never refers to “gm enhancement” as a function separate from “gm boosting.” Indeed, the transistors (368, 370, and 382) that Patent Owner identifies as performing the function of “gm enhancement” are disclosed as part of a “gm-boost stage.” Ex. 1001, 5:8–24. Patent Owner’s alleged separation of Figure 3B into distinct “gm boosting” and “gm enhancement” is not consistent with the intrinsic evidence and is based on the conclusory testimony of Dr. Taylor. Thus, based on the evidence of record, we disagree with Patent Owner’s proposed construction distinguishing the terms “gm enhanced” and “gm-boost” in claim 1. Rather, we find persuasive Petitioner’s argument that a person of ordinary skill in the art would have regarded these terms to be synonymous.

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Patent Owner asserts that a person of ordinary skill in the art at the time of filing “would have had a Bachelor’s degree in electrical engineering, computer science, or the like, and/or four or more years of experience in server-based applications” and that “[a]dditional experience may make up for a lack of education and vice versa.” PO Resp. 9. Because Petitioner’s proposed level of ordinary skill in the art appears to be consistent with the challenged patent and prior art, we adopt it and use “skilled artisans” to refer to people with such skill at the time the invention was filed. We do not perceive a substantive distinction between the parties’ definitions, but note that Petitioner’s definition provides more detail about the capabilities of skilled artisans. Also, the level of ordinary skill in the art can be evidenced by the references cited, and we find it commensurate with the cited references in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978).” slip op. at 9

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

    “device indicated by the session data” encompasses “determining a notification method based on” session data indicating the current state of the external device, where the current state of the device encompasses an online state as well as an offline state. See Pet. 53–54; Tr. 55:3–10 (The Board: “Are there any other states of an external device other than online or offline?” Patent Owner: “As far as I know, Your Honor, those are the only two[.]”), Tr. 65:24–66:1 (The Board: “When the claim says current state, they mean it’s online or offline?” Petitioner: “Correct.”), Tr. 20:23–21:8. The specification is consistent with the plain language of the claim in disclosing two examples of the claimed “current state,” namely, online and offline. Ex. 1101, 21:1–4. The specification discloses that the notification manager “queries session manager 456 to determine the user’s connectedness.” Id. at 21:6–8. The specification discloses that if the user is “online, notify by, for example, the user’s active session. If offline, notify by, for example, a txt [sic] message, call the user’s landline, call a friend of the user, and the like.” Id. at 21:1–4, 23:28–31.” slip op. at 13

  • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

    “Patent Owner’s expert witness, Dr. Goodrich, show written description support for providing a notification to an active external device, Patent Owner has not cited any portion of the 2009 Parent, nor any portion of the testimony of Dr. Goodrich, to show that the 2009 Parent provides written description support for determining a notification method by which to provide an alert to an external device based on the current state of the external device as offline. We highlight that Paragraphs 130 and 131 of the 2011 CIP Application disclose offline notification preferences for determining a notification method by which to provide an alert to an external device based on the current state of the external device as offline. Ex. 1110 ¶¶ 130–131. Specifically, paragraphs 130 and 131 describe that: the notification manager of the eventing and alerting subsystem 452 queries the configuration server 454 for the user's notification preferences and correlates these notification preferences with session manager 456 to determine the best notification method. That is, the notification manager queries the configuration server 454 and determines, for example, that the user has certain online notification preferences and certain offline notification preferences. If online, notify by, for example, the user's active session. If offline, notify by, for example, a txt message. . . . The notification manager of the eventing and alerting subsystem 452 then queries session manager 456 to determine the user's connectedness. Id. That is, if the user’s connectedness, or “current state” of the claimed external device, is offline, and the user’s offline notification preferences are “notify by txt message,” the notification manager will determine that the notification method for the external device having a current state of offline is by txt message. See id. Thus, the 2011 CIP Application describes a notification manager that queries a session manager to determine whether an external device is offline, and if the external device is offline, determines a notification method for providing an alert on the external device based on the current status of the external device as offline and the user’s offline notification preferences. Although we find this written description support for the determining limitation in the 2011 CIP Application, we do not find this written description support in the 2009 Parent.” slip op. at 25

    “As to the “determining a notification method” limitation (1.10), Petitioner asserts that Austin-Lane teaches determining: (1) the user device(s) to send the notification to (e.g., phone, PDA, notebook computer, desktop computer); (2) the communication protocol to use to send the notification, i.e., how to send the notification (e.g., SMTP (for email), SMS (for texts), HTTP (for web browsers)); and (3) the type of alert to provide, i.e., how to present the notification, (e.g., text, an icon, a pop-up window, a video, an email, an audible or tactile alarm), based on the current state of the at least one external device indicated by the session data (“presence information”), which may include whether and on which device(s) the user is online and/or whether and on which applications the user has an active session. Id. at 53 (internal citations omitted) (citing Ex. 1105 ¶¶ 4, 5, 29, 32, 33, 39, 46, 48, 61, 79, Fig. 1). We highlight that paragraph 61 of Austin-Lane discloses that: The type preferences 650 may include preferences for various notification types. . . . [A]uction alert #1 660 defines the following delivery precedence 663: (1) a web browser (if the user is online), (2) an IM client (if the user is online), (3) a mobile phone #1, (4) a PDA, (5) a mobile phone #2, (6) a pager, and (7) an email inbox. Ex. 1105 ¶ 61; see id. ¶¶ 74–77 (Describing that one of several notification methods for delivering an alert to a user’s device is determined based on the current state of the user’s device as online or offline).

    “it was “known to utilize ‘cues’ to help the user know what gesture to utilize and whether they are correctly performing the gesture (e.g., graphics such as movable images that help the user visualize the correct gesture and how to complete it successfully).” Pet. 40 (citing Ex. 1005, Abstract, ¶¶ 54, 62, 73). This sentence does not cure the deficiency noted above regarding Petitioner’s reliance on Ahn’s graphic shadow moving with a gesture. Chaudhri is relied on for the proposition that, Ahn’s graphic shadow is “[i]ndeed” a movable image known to give a user a visual cue. Id. But no such “cue” is provided in Ahn by the graphical shadow alone, because there is no movement of that object. The Petition does not present argument that a Chaudhri object is the movable object or how any of Chaudhri’s teachings of movable objects would have suggested to modify Ahn “to thereby move” the graphical shadow.” slip op. at 18

  • Strike new argumentNew argument disregardedDecided for patent owner

    “the theory that Ahn’s graphic shadow moves. Reply 3−4. Petitioner interprets the sentences in Ahn we have analyzed above in conjunction with testimony of Dr. Terveen to argue that temporal descriptions in Ahn make it obvious for a person of ordinary skill in the art to drag in the right direction while continuing to press the graphic 1800. Id. (citing Exs. 1004 ¶¶ 117−119, Ex. 1023 ¶ 10). The Petition, however, relies on an Ahn disclosing a moving graphic shadow according to the embodiment of Figure 18(a), as described in paragraph 118. Petitioner now changes its theory of how Ahn’s graphic shadow would move according to paragraph 119, i.e., that although the graphic shadow is merely pressed (in the embodiment shown in Figure 18(b)) it would also be dragged while pressed. Reply 3. Not only is this a shift from the theory Petitioner presents in the Petition, it is not persuasive. As Patent Owner argues, and we agree, there is no cogent explanation for modifying the graphic shadow embodiment of Figure 18(b), especially in light of Ahn’s disclosure that the graphic shadow disappears when pressed and the menu list is displayed as emerging. Sur-reply 2−3. In other words, Petitioner’s new argument does not account for Ahn’s teaching that the objective of the graphic shadow is merely to notify the user of the start of the gesture, and once that start of the gesture is detected (the press on the graphic shadow), paragraph 119 informs us that there is no longer a need for the graphic shadow—it disappears from the display. Ex. 1004 ¶ 119. The Petition does not offer any argument for a theory in which the gesture of paragraph 119 (the press, not a touch and drag operation) results in graphic 1800 disappearing, while also moving during the disappearance. We are mindful that “[i]t is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests to one skilled in the art.” Bausch & Lomb, Inc. v. Barnes-Hind / Hydrocurve, Inc., 796 F.2d 443, 448 (Fed. Cir. 1986)). Consequently, we determine that Petitioner’s argument in Reply belatedly relying on the different embodiment of paragraph 119 is improper new argument, and that even if considered it is not persuasive.” slip op. at 20

    “Following the Institution Decision, both parties submitted proposed claim constructions in the district court stating that the preamble is limiting. Ex. 2009, 3–4 (Petitioner’s Preliminary Claim Construction Chart); Ex. 2010, 7 (Patent Owner’s Preliminary Claim Construction Chart). Patent Owner states in the Patent Owner Response that “[t]he parties now agree that the entire preambles of both claims 1 and 6 are limiting.” PO Resp. 17. In its Reply, Petitioner states that “whether the Board finds the phrase ‘service auto-configuration’” in the preamble to be limiting is “immaterial” because it “does not affect the analysis of whether the prior art cited in the petition invalidates [the challenged] claims.” Pet. Reply 5. At the oral hearing, Petitioner acknowledged that it does not dispute that the entire preamble of claims 1 and 6 is limiting. Tr. 20:25–21:17, 23:15–17. Because the parties agreed in district court that the entire preamble of claims 1 and 6 is limiting, and also agree in this proceeding, we find that the preambles of claims 1 and 6 are limiting for purposes of this Decision.

    “Based on the full trial record, we find that Petitioner has failed to meet its burden to show that Bernstein recites a “service auto-configuration” method as recited in the preamble of claim 1. As discussed above, the parties agree that the preamble of claim 1, including the “service auto-configuration method” language, is limiting. See § II.B, supra. As we explained in the Institution Decision, the Petition does not set forth a construction of “service auto-configuration method” or explain how the prior art discloses a “service auto-configuration method.” Pet. 11, 24; Inst.

Instead, the Petition merely explains how Bernstein teaches “a DOCSIS Provisioning of EPON (DPoE) system,” without explaining how it teaches a “service auto-configuration method.” Pet. 24 (citing Ex. 1005 ¶ 59). By failing to offer a construction of “service auto-configuration method” or explain how this limitation is met by the prior art, the Petition fails to show by a preponderance of the evidence that the prior art discloses or suggests this limitation.” slip op. at 34
