    “Petitioner proposes that a “person of ordinary skill in the art (‘POSITA’) in the field of the ’317 patent would have [had a] bachelor’s degree in engineering or computer science and two years of experience working on NLP [natural language processing] or automation processes” or “[a]lternatively . . . would have [had] five to six years of experience working on NLP or automation processes.” Pet. 6 (citing Ex. 1003 ¶¶ 43–45). We adopted Petitioner’s proposal for purposes of the Decision on Institution, explaining that it appeared to be consistent with the evidence of record, including the asserted prior art and the ’317 patent. Dec. 12. is inconsistent with the asserted Symons prior art and with factors (4)–(6) set forth in Daiichi Sankyo. PO Resp. 20–21 (citing Ex. 2002 ¶¶ 36–45). According to Patent Owner, the technology of the ’317 patent was “evolving rapidly” and the level of sophistication in the technology was “relatively low” in November 2017. Id. at 21–22 (citing Ex. 1004, 1–2; Ex. 1009, 2; Ex. 2002 ¶ 42; Ex. 2003 (transcript of June 26, 2024, deposition of Dr. Beigi), 141:2–9, 191:18–197:5; Ex. 2007; Ex. 2008).

Accordingly, Patent Owner argues, “[t]he evidence of record demonstrates a more appropriate level of skill would [be] a worker who had some education, formal or informal, in computer science and 1–2 years’ work experience with chatbots using NLP and/or automation processes.” Id.

    “Ex. 1042 ¶¶ 35–37). Further, Petitioner asserts, “the Petition relies on Williams, not Symons, for its teachings of a ‘web-based’ target system.” Id. (citing Pet. 40). Petitioner does not, however, address Patent Owner’s main point, i.e., that the Petition relies on Symons’s illustration of its RPA bot purportedly filling in a text input field in the GUI of the Cronos Email Signature Generator for limitation 1[g] but relies on Symons’s illustration of its RPA bot interacting with a widget in Internet Explorer for limitation 1[h], despite the recitation in limitation 1[h] of “interacting with a widget in the GUI.” See, e.g., PO Resp. 38. Dr. Beigi acknowledges that, “[a]ccording to the ’317 patent, a widget is a GUI element,” and he concludes, with reference to Petitioner’s annotated version of the screenshot from page 13 of Exhibit 1006 reproduced above, that “Symon[s]’s GUI button is a widget in a GUI.” Ex. 1003 ¶ 100 (emphasis added) (citing Ex. 1001, 10:19–21). But neither the Petition, nor the Reply, nor Dr. Beigi’s testimony persuasively explains how a dialog box in Internet Explorer teaches or suggests a widget in the Cronos GUI. The Reply’s contention that “the Petition relies on Williams . . . for its teachings of a ‘web-based’ target system” is unavailing, because the issue is not whether either the Cronos program or Internet Explorer is “web-based”12 but whether Petitioner has identified a teaching or suggestion of an implementation of an automation process that fills in a text input field in a GUI of a web-based target system and interacts with a widget in the same GUI. 12 In this regard, we credit Mr. Zatkovich’s statement that Internet Explorer is local to and resident on the user’s computer.

More specifically, Petitioner fails to explain how or why a person of ordinary skill in the art would be motivated to perform Krishnan’s automation process (i.e., fulfilling customer requests) by implementing an “automation process by interacting with a Graphical User Interface (GUI)” and “simulating user input to the GUI,” as purportedly taught by Radhakrishnan. Petitioner’s arguments are focused toward using Radhakrishnan’s RPA bot to perform Krishnan’s customer service requests (i.e., automation process) but fail to explain how Radhakrishnan’s RPA bot’s mirroring of the user’s operations (i.e., the simulation on the displayed user interface) as applied in Krishnan would work or provide sufficient reasoning to do so.

    “Petitioner, supported by the testimony of Dr. Reader, argues that a person of ordinary skill in the art (“POSITA”) “would have a bachelor’s degree, or equivalent, in electrical engineering, computer science, a related field, and 2–3 years’ experience researching, designing, or developing content delivery systems and related hardware, software, and firmware, or equivalent experience.” Pet. 14 (citing Ex. 1006 ¶¶ 67–69). Petitioner further argues “[o]ne having less education but more practical experience, or more education and less experience, might also meet this standard.” Id. Patent Owner does not dispute Petitioner’s definition or offer an alternative level or skill in the art. PO Resp. 12 (citing Pet. 14; Ex. 2012). Instead, “[f]or the purposes of this PO Response only, Patent Owner applies Petitioner’s definition of POSITA.” Id. Thus, on this record, the parties agree upon the proposed level of ordinary skill in the art, and this level is consistent with our review and understanding of the technology and descriptions in the ’101 patent and the prior art references that disclose content delivery systems.

    “the gap between the playback deadline and the target schedule, (td(n) − tT(n)), is the target buffer duration, i.e., ‘the desired client buffer duration (in client time).’” Id. at 22–23 (quoting Chou ¶ 74). Petitioner also argues that “in efforts to match upper bound tb(n) to target schedule tT(n), Chou takes into consideration the time duration between target schedule tT(n) and the playback deadline td(n).” Thus, it appears Petitioner assembles three separate and distinct time intervals from Chou’s timing diagrams and equations to construct one contiguous time interval equivalent to claim 1’s remaining time. However, Chou does not recognize the time interval that Petitioner posits, and Petitioner has not persuasively shown that this combined time interval exists as a teaching in the prior art and is used as part of any step or decision involved in determining the code rate. As admitted by Petitioner’s expert, Dr. Reader, Petitioner’s analysis “used the claims as a road map to find limitations in the prior art.” Ex. 2015, 76:4–9 (Reader Deposition Transcript). See also Tr. 28:20–31:2 (Petitioner’s response to whether identification of and integration of separate time ranges described by Chou is hindsight reconstruction, Petitioner argues Chou’s device operates such that code rate is based on remaining time). Under the circumstances, this is improper because Petitioner and Dr. Reader do not justify this combination of separately identified time ranges except based solely on hindsight reconstruction of the claimed invention. However, even if that were not the case, we are not persuaded that Chou or the other asserted prior art references suggest using the combined time interval td(n) − ta(n) as the basis for any decision related to determining the code rate.” slip op. at 37

    “d) Analysis In our Institution Decision, although expressing some uncertainty with respect to certain of Patent Owner’s arguments on the preliminary record then before us, “we [were] not persuaded by Petitioner’s contentions that [(1)] Wang teaches [1d]’s code rate” (Dec. 53 (citing Pet. 62–65) or (2) “a POSITA would have been motivated to combine the teachings of Chou and Wang” (id. at 54 (citing Pet. 74)). Petitioner does not dispute those determinations in its Reply or otherwise. Furthermore, Petitioner does not address or otherwise dispute Patent Owner’s arguments challenging the asserted obviousness of claims 1, 4–6, 10–16, and 19–26 over the combined teachings of Chou and Wang. Thus, for at least the reasons set forth in our Institution Decision, we agree with Patent Owner that Petitioner fails to show that (1) one skilled in the art would have combined the teachings of Chou and Wang or (2) the combined teaching of Chou and Wang renders limitation 1(d) obvious. e) Conclusion Regarding Claim 1 For the foregoing reasons, we determine that Petitioner has not shown by a preponderance of the evidence that independent claim 1 is unpatentable over the combination of Chou and Wang.” slip op. at 47

    “Having considered the parties’ arguments, we agree with Petitioner that the recited “system” of claim 35 does not necessarily exclude a “third-party second media property.” As Petitioner points out, claim 35 uses the open-ended transitional phrase “comprising,” such that the recited “system comprising one or more computers” may include components other than the recited “one or more computers.” See Pet. Reply 1 (citing CIAS, Inc. v. All. Gaming Corp., 504 F.3d 1356, 1360 (Fed. Cir. 2007)). Moreover, we agree with Petitioner that the phrase “programmed to implement a method of directing electronic advertisements” more naturally modifies “one or more computers,” rather than “system.” Id. at 3. Nonetheless, it is clear from the plain language of claim 35, as well as from the prosecution history of the related ’745 patent, that the third-party second media property must be distinct from such “one or more computers.” Petitioner’s repeated use of the abbreviation “TPSMP” obscures the fact that claim 35 does not simply recite a “second media property” but instead specifically recites a “third-party second media property.” Ex. 1001, 16:18–19 (emphasis added). Highlighting the significance of the modifier “third-party,” as Patent Owner points out, is the fact that that modifier was added to “second media property” in the phrase “automatically electronically authorizing, with at least one of the computers, a third party second media property to allow display, to the electronic visitor when later visiting the second media property, of an advertisement” in an Examiner’s amendment during prosecution of the ’822 patent’s grandparent ’286 application to avoid certain prior art, and the prosecution record of the ’286 application reflects that this amendment was made to make it clear that the recited “authorizing is being done of an unrelated site.” Ex. 2005, 58; see PO Resp. 10–11. More particularly, as Patent Owner points out, the applicant stated in the cited examiner interview report that “the claim structure already made [it] clear” that “the authorizing is being done of an unrelated site . . . because the phrase ‘authorizing’ a site does not seem to cover a site deciding something on its own,” but that the amendment to specify a “third party second media property” made that requirement “explicit.” Ex. 2005, 58; see PO Resp. 7–8 (quoting the same).” slip op. at 23

    “Having considered the parties’ respective contentions in light of the evidence of record, we conclude that Petitioner has not established by a preponderance of the evidence that claim 35 is unpatentable over the combination of Perry, Wilson, and Bronson. In particular, we are not persuaded that the cited prior art teaches or suggests “a system comprising one or more computers programmed to implement a method . . . comprising: . . . automatically electronically authorizing a third-party second media property to allow display . . . of an advertisement correlated with the profile-attribute information received about the visitor.” Although Figure 1 of Perry depicts a “system” that includes computers programmed to implement a method of distributing advertisements to users over the Internet, we are not persuaded that any component in that system implements a method that includes “automatically electronically authorizing a third-party second media property” to display such advertisements. As Patent Owner points out, Petitioner identifies “Internet publisher computer systems 131 and 132” and “advertising service company computer system 140 comprising one or more CPUs 141” as the recited “one or more computers.” Pet. 7; PO Resp. 11. Although there is no dispute that Publisher Systems 131 and 132 and ASC 140 are computers, we find that neither satisfies the remaining limitations of claim 35, particularly because neither “automatically electronically authoriz[es] a third-party second media property” to display advertisements. As we explain in our claim construction discussion above, we are not persuaded by Patent Owner’s arguments that the recited “system” necessarily must exclude the “third-party second media server.” See supra § III.C. Nonetheless, the third-party second media server still must be separate and distinct from the “one or more computers programmed to implement [the recited] method,” lest the modifier “third-party” be rendered meaningless.” slip op. at 54

The definite article “the” can be used to modify something plural, e.g., “the digital representations.” Although in claim 1, “the” is used to modify a “digital representation,” that does not help the Patent Owner, because nothing in the claim excludes the involvement of additional digital representations while one “digital representation” is analyzed. Patent Owner points to nothing in claim 1 which restricts the analyzing to “only” one digital representation or “no more” than one digital representation, and we see none. Further, claim 1 uses the non-limiting phrase “comprising,” which creates a presumption that the claim is not limited to only those elements expressly recited in the claim. Crystal Semiconductor Corp. v. TriTech Microelectronics Int’l, Inc., 246 F.3d 1336, 1348 (Fed. Cir. 2001). We recognize that the only embodiment described in the specification of the ’036 patent analyzes only a single digital representation, but we are not required to construe the claim as limited to just that embodiment. Innova/Pre Water, Inc. v. Safari Water Filtration Systems, Inc., 381 F.3d 1111, 1121–22 (Fed. Cir. 2004). Such a construction is neither encouraged nor presumed. Id. Additionally, Patent Owner points to no expressions of disavowal either in the prosecution history or in the specification of the ’036 patent with regard to “a digital representation” in which the patent applicant disavows, with clarity, claim scope covering analysis of more than one digital representation. For the foregoing reasons, we disagree with Patent Owner, and we determine that analyzing “a digital representation” as recited in claim 1 does not preclude involvement of an additional digital representation or digital representations in the analysis.” slip op. at 17

Based on Patent Owner’s arguments, we are not persuaded that the ’639 provisional demonstrates possession by the inventors of linking a DSP to the Downloadable “before a web server makes the Downloadable available to web clients.” Rather, by the time that the DSP has been linked to the Downloadable (e.g., by code scanner 325, in Patent Owner’s mapping), we understand that the Downloadable has already been received—and hence “made available”—by the web server. Notably, this conclusion does not depend on where the “linking” occurs—particularly, whether it may occur at a network gateway, a focus of the parties’ claim construction arguments (see, e.g., Pet. 25–27; PO Resp. 10–12; Section II.B.5, supra)—but instead on when it occurs relative to the Downloadable being made available to clients. Further, having considered the alleged Appendix to the ’639 provisional (Ex. 2015, 37–45), including portions cited by Dr. Butler in related litigation (see Ex. 2047), we are not persuaded that anything in the Appendix demonstrates possession of linking “before a web server makes the Downloadable available to web clients.” In conclusion, therefore, we are not persuaded that the inventors were in possession of the subject matter of the challenged claims at any time prior to the December 22, 1997, filing date of the ’648 application.” slip op. at 35

    “Tempered against Petitioner’s evidence of an alleged motivation to combine MR810, Gradon, and Edirisuriya is the uncertainty of operability of the proposed combination. With respect to each of the proposed circuit designs that Petitioner contends a skilled artisan would have been aware of to implement the combined teachings, a skilled artisan would have been faced with the real-world fact that there was uncertainty as to the operability of the design. First, the circuit designs that Petitioner proposes a skilled artisan would have utilized are not based on disclosure in the prior art. See Pet. Reply 5–7; Ex. 1032 ¶¶ 13–22. Petitioner does not rely on any prior art showing a circuit that allows a heater wire also to carry measurement signals. Pet.

Moreover, Petitioner does not otherwise sufficiently rely on evidence that any of the proposed circuit designs would have been reasonably expected to be operable in any device, much less a humidification system. See Pet. Reply 5–7. Furthermore, Mr. Bath admits that these proposed designs are incomplete and would require additional non-trivial components. Ex. 2018, 89:13–90:21.

    “We further find that Petitioner’s challenges rest on impermissible hindsight reconstruction of the disclosure in the ’641 patent. See Grain Processing Corp. v. Am.-Maize Prods. Co., 840 F.2d 902, 907 (Fed. Cir. 1988) (“Care must be taken to avoid hindsight reconstruction by using ‘the patent in suit as a guide through the maze of prior art references, combining the right references in the right way so as to achieve the result of the claims in suit.’” (quoting Orthopedic Equip. Co. v. United States, 702 F.2d 1005, 1012 (Fed. Cir. 1983))). All of the circuit designs Petitioner proposes a skilled artisan could have used to implement the asserted combination are hindsight reconstructions based on the disclosure in the ’641 patent. The ’641 patent describes switching the heater wire between two modes of use— carrying temperature measurement signals and heating the gas delivery tube —by inserting a component in parallel with a temperature measuring thermistor to switch the current path of the heater wire between the thermistor and the parallel-connected component. Specifically, the ’641 patent discloses switching the current flowing in heater wire 21, 28 between the parallel paths of thermistor 23 and diode 22, depending on whether heater wire 21, 28 is being used to carry temperature measurement signals or heat gas delivery tube 3, respectively. Ex. 1001, 4:8–21. Each of Petitioner’s proposed circuits, drawn solely from the testimony of Mr. Bath and not supported by the prior art, has a similar purpose. Petitioner’s first proposed circuit contains a capacitor connected in parallel with a thermistor to switch the path of the heating wire current between the thermistor, when the heating wire is being used to carry temperature measurement signals, and the capacitor, when the heating wire is being used to heat the breathing tube.

(citing Tempo Lighting Inc. v. Tivoli LLC, 742 F.3d 973, 978 (Fed. Cir. 2014)). The Federal Circuit has emphasized that, even under the broadest reasonable interpretation, “the Board’s construction ‘cannot be divorced from the specification and record evidence,’” id.

    “unpatentability, we determine that there are multiple deficiencies with Petitioner’s showing with respect to the proposed combination as related to specifically recited claim limitations. See 35 U.S.C. § 316(e); 35 U.S.C. § 312(a) (requiring the petition to identify “in writing and with particularity . . . the grounds on which the challenge to each claim is based”); see also 37 C.F.R. § 42.104(b) (requiring “a statement of the precise relief request”). Because we find that even the combination, if effected in the manner proposed by Petitioner, does not meet all limitations recited in the challenged claims, we do not reach the issue of whether Petitioner articulates sufficient reasoning with rational underpinning to effect the combination. See Pet. 21–28; PO Resp. 21–47. First, we agree with Patent Owner that Petitioner insufficiently shows that the combination it proposes teaches or suggests “using the routing channel number as an index to select the destination point to which the 7 Although we rely on illustrations of Petitioner’s proposed combination as set forth in the Reply because they are more clear, we find those illustrations consistent with the position taken by Petitioner in the Petition. See Pet. 24– 27. controller subsequently sends the data.” PO Resp. 59–61. This limitation is recited in both independent claims 1 and 12 in the context of searching for a destination point of the data in the routing table. Ex. 1001, col. 19, ll. 6–9, col. 20, ll. 40–43. In articulating how it draws a correspondence between elements recited in the claims and entries of its proposed routing table, Petitioner makes the following identifications: (1) the recited “routing channel number” corresponds to the channel identifier in the inbound VCI allocated to a first data path defined by the card access module and router; (2) the recited “source point” corresponds to “an identifier of the SAP associated with a smart card application on the contact smart card . . . in the inbound ‘VPI’; and (3) the recited “destination point” corresponds to “an identifier of an SAP associated with software . . . in the outbound VPI.” Pet. 36. With these correspondences, we agree with Patent Owner that the channel identifier in the inbound VCI cannot function as an “index to select the destination point” as the claims require because there is no unique association of the outbound VPI with the inbound VCI.8 PO Resp. 59. This is evident from the table provided in the Reply, and reproduced above, in 8 Although we agree with Petitioner, as explained above in Section II.C.3, that a construction of “routing table” does not require a “one-to-one correspondence between the routing channel number and each corresponding routing parameter,” see PO Resp. 57 (emphasis added), the nature of an “index” nevertheless requires a unique association of the index with what it indexes. That is, an “index to select the destination point” must uniquely identify the selected destination point, even if the same destination point can be selected by multiple indexes. A “one-to-one” correspondence would additionally require that each destination point be selected only by a single index. which the same VCIin value of “Chin 1” is associated with different values of VPIout, namely “CPU SAP 1” in the first row and “RF SAP 1” in the third row.” slip op. at 29

    “At the oral hearing, we expressed surprise that a party would seek to exclude the cross-examination testimony of its own expert witness. See Tr. 49:19–52:8. Patent Owner’s counsel explained that it “provided a motion to exclude based on the way that the evidence was used in the reply.” Tr. 50:1–6. But the Board has previously explained that “neither a motion to strike nor a motion to exclude is a proper mechanism to present argument that a reply contains new arguments.” Ultratec, Inc. v. Sorenson Communications, Inc., Case IPR2013-00288, Paper 38 at 2 (PTAB May 23, 2014). Rather, an evaluation of the propriety of, and weight to be accorded to, arguments made in a reply is left to the determination of the Board, with parties afforded various opportunities to provide context for the evidence. See 37 C.F.R. §§ 42.23, 42.65. We, therefore, consider Patent Owner’s arguments as going to the weight that should be given to the cross-examination testimony and related deposition exhibit, not to the admissibility of that evidence. See Liquid Dynamics Corp. v. Vaughan Co., 449 F.3d 1209, 1221 (Fed. Cir. 2006) (“Vaughan’s challenge goes to the weight of the evidence rather than the admissibility of Lueptow’s testimony and analysis.”). As indicated above, we have considered and weighed the testimony provided by Dr. Medvidovic and have not relied on the testimony of Dr. Bims in reaching our decision. Accordingly, we deny Patent Owner’s Motion to Exclude.” slip op. at 25
