    “First, the claims use present-tense language, “one or more other connections, which have respective bandwidths and which are permitted to share a bandwidth allocation with the new connection.”3 Ex. 1001, claim 1 (emphasis added). The exclusive use of the present tense have indicates “other connections” must have current possession of the bandwidth. For these other connections to share bandwidth with a newly established connection, they must already exist and have bandwidth ready for immediate use, rather than merely holding a dormant “reservation” pending a network failure.

    “combination, do not teach or suggest limitations 1.2 and 1.3 requiring: providing a sharing definition specifying one or more other connections, which have respective bandwidths and which are permitted to share a bandwidth allocation with the new connection, such that a total bandwidth allocated jointly to the new connection and to the other connections in any given segment is equal to a maximum of the requested bandwidth and of the bandwidths of the other connections in the given segment Ex. 1001, limitations 1.2, 1.3 (emphasis added); see PO Resp. 17–22; Sur-reply 4–5, 12–14. As discussed above in Section II.C.2, we interpret “other connections” to mean “existing connections in the network that already have bandwidth allocated to them.” Because the information shared in Dziong and Sathyanath, described below, relates to reserved protection paths, rather than existing connections that have bandwidth that can currently transmit network traffic, the references do not teach or suggest the “other connections” part of the sharing definition in limitations 1.2 and 1.3. Dziong describes advertising, across the network, the amount of bandwidth reserved for recovery on each link that would be activated when a protected link fails. See, e.g., Ex. 1005 ¶ 60; Pet. 36. Once activated, network traffic from a “primary path” failure is rerouted to these recovery paths. See Ex. 1005 ¶¶ 7–9, 70, 83. Petitioner points to this advertising of the reserved bandwidth information as teaching the claimed “sharing definition.” Pet. 33–36 (arguing that the “protection paths [in Dziong] have bandwidth reservations” and “share an overall protection bandwidth reservation”); Reply 21–23. However, since the advertised information only contains information about the recovery paths “that would be activated” upon a primary path failure, such paths are not existing connections that already have bandwidth allocated to them, and therefore do not teach the claimed “other connections” that are part of the sharing definition.

More specifically, Petitioner argues, a person of ordinary skill in the art “would have had a master’s degree in computer science, computer engineering, or an equivalent, and two years of professional experience relating to network communications and resource allocations,” where “[a]dditional work experience can substitute for specific educational background, and vice versa.” Id.

Specifically, according to Patent Owner, Petitioner proposed that “predetermined” be construed as “determined before the data flow request” and that “quantum” be construed as “an amount of a requested resource by which to increase or decrease.” Id. (citing Ex. 2007). Patent Owner contends asserted prior art combinations disclose or render obvious the challenged claims under these constructions. Id. Because our conclusion that Petitioner has not demonstrated that any of the challenged claims are unpatentable does not turn on the construction of either “predetermined” or “quantum,” there is no need for us to construe those terms.

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.

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

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

  • Skill levelSkill level petitioner adoptedOther

    “We adopt Petitioner’s articulation of the level of ordinary skill in the art, minus the phrases “at least” modifying the education and “or more” modifying the number of years of experience. As we explained in our Institution Decision, although Petitioner’s articulation otherwise appears consistent with the level of skill in the art at the time of the invention as reflected in the asserted prior art, inclusion of such qualifiers render the articulation vague by being open-ended thus encompassing the level of education and experience of an expert, someone with more than ordinary skill in the art. See Dec. 12. Thus, in summary, we find that one with ordinary skill in the art at the pertinent time period would have had a bachelor’s degree in computer science, electrical engineering, computer engineering, or the equivalent, and two years of experience with designing, programming, configuration, and/or analysis/research with Internet or similar network-related processes including, for example, user/entity profile management and/or web-based targeted content delivery, or a related field, where more education could supplement practical experience and vice versa.” slip op. at 12

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableNot shown unpatentable

    “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

We also agree with Patent Owner that the claimed “linking” of a DSP “to the Downloadable” does not compel a different understanding because we are not persuaded that the linking contemplated in the ’844 patent requires modification of the code of the Downloadable itself.

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

    “adequately address the pertinent issue—whether Petitioner’s proposed hypothetical person of ordinary skill in the art would lack the requisite experience and understanding of the art. Patent Owner does not identify adequately a substantive difference between Petitioner’s hypothetical person of ordinary skill in the art and Patent Owner’s. See PO Resp. 17–20. For example, Patent Owner does not argue that an electrical engineer or physicist with two years of experience utilizing electronic circuit testing equipment would lack adequate knowledge of the use of lasers in circuit testing. To the contrary, Patent Owner’s expert, Dr. Woods, “generally agree[s] with petitioner’s definition of a [person of ordinary skill in the art]”—including the type of education and level of experience—and testified that “[t]hese techniques [of OBIRCH and TIVA] were known and widely used around the time of the invention of the ’982 patent to determine the location of defects in a semiconductor device and would have been known to those of ordinary skill in the art.” Ex. 2029 ¶¶ 30–31. To the extent that Patent Owner’s proposed definition of the level of ordinary skill is more than merely an elaboration upon Petitioner’s, we find it to be directed to a super-expert in a very narrowly defined field and calculated to undermine Dr. Mercer’s credibility while simultaneously promoting the credentials of its own experts. We do not find this litigation-induced argument persuasive. We determine that the definition offered by Dr. Mercer comports with the qualifications a person would have needed to understand and implement the teachings of the ’982 patent and the prior art of record. Cf. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself may reflect an appropriate level of skill in the art).

    “In support of its case, Petitioner reasons that “a POSITA would have considered it obvious to have configured Hamada’s electrical current meter 6 to determine a plurality of samples of the response signal, and to have configured signal processing and display 9 to add up this plurality of samples, in order to optimize Hamada’s averaging process.” Pet. at 23 (emphasis added) (citing Ex. 1004 ¶ 24; Ex. 1014 ¶ 205). Neither Petitioner nor its expert elaborates on the conclusory assertion that performing the claimed determining and accumulating steps would have “optimize[d]” Hamada’s averaging process. Petitioner further reasons that: it would have been obvious for a POSITA at the time of the invention to have configured electrical current meter 6 and signal processing and display unit 9 to respectively measure and add multiple samples of the response signal to allow Hamada’s averaging process, in turn, to be performed on multiple samples. Id. at 24 (citing Ex. 1014 ¶ 206). This reasoning is circular in that it is, effectively, an assertion that it would have been obvious to perform operations on multiple samples in order to perform the process on multiple samples. We also have considered Petitioner’s arguments in the Petition that the “motivation” comes from the “teaching or suggestion” provided by the disclosure of “averaging,” along with Petitioner’s string of reasons from KSR International Co. v. Teleflex Inc., 550 U.S. 398 (2007). See Pet. 24, 43–44 (citing Ex. 1014 ¶¶ 206, 306). Petitioner does not develop adequately any of these reasons. An obviousness analysis requires more than “mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). In its Reply, Petitioner repackages its “[b]y definition” argument as purportedly an obviousness argument. Pet. Reply 19–20. Petitioner argues that, “to the extent that Hamada does not explicitly disclose this limitation, a POSITA would have considered the act of configuring Hamada to measure and add multiple samples to have been obvious because that is what the definition of ‘averaging’ requires.” Id. (citing Pet. 23–26; Ex. 1014 ¶¶ 204– 208). Although possibly an obviousness theory, this argument reads more like an assertion that the claimed determining and accumulating of a plurality of samples either is inherently or implicitly disclosed in Hamada (offered as an alternative if it is deemed not explicitly disclosed). Thus, Petitioner appears to take the position that the disputed limitation is not absent from Hamada, and Petitioner fails to explain why a person of ordinary skill would have seen a reason to modify Hamada. For the reasons discussed above, we do not find Petitioner’s “[b]y definition” argument persuasive in the anticipation context and, for those same reasons, do not find it persuasive when couched as an obviousness ground. We determine that Petitioner has failed to demonstrate that independent claim 1 would have been obvious over Hamada. Petitioner’s arguments as to dependent claims 2, 3, 8–16, 19, and 20 (Pet. 24–26, 44–45, 47) do not cure the underlying defect in its obviousness theory with regard to independent claim 1. Accordingly, Petitioner also has not demonstrated that those dependent claims would have been obvious over Hamada. F. The Remaining Obviousness Grounds Based on Hamada in Combination” slip op. at 29
