At column 3, Smith discusses in general terms that a roadside billboard “may be viewed as effective (or at least more effective) where analytics data indicates a large number [of] user[] visits to a website advertised by the billboard, and the users are in close proximity to the billboard at or near the time of initiating the website visit.” Ex. 1032, 3:40–45. Likewise, at column 4, Smith further discloses using analytics data to assess the effectiveness of a promotion at a geographic location. Id. at 4:32–43. The cited portions of Smith, thus, disclose processing data from a large number of users to judge the effectiveness of the overall campaign. Petitioner does not direct us to any disclosure in Smith that the effectiveness processing module uses a specific action taken by a specific user, as taught by the ’219 patent, in determining that a particular browser session was initiated by a user with an intent to visit the URL.” slip op. at 19

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

      “We disagree with Petitioner’s arguments. Claim 1 recites “a decoy computer system [that] comprises . . . a virtual machine monitor,” and “at the virtual machine monitor: . . . creating, from the stored activities, a fingerprint.” Ex. 1001, 19:4–22. Thus, the claim’s plain language requires creating a fingerprint at the virtual machine monitor, not just at the decoy system, as Petitioner asserts. When, as here, a claim term has “ordinary, simple English words whose meaning is clear and unquestionable,” we may not redraft those words to mean something different. Chef America, Inc. v. Lamb-Weston, Inc., 358 F.3d 1371, 1373–75 (Fed. Cir. 2004). Petitioner offers no explanation how one skilled in the art might read “at the virtual machine monitor” to mean at the decoy system, rather than at the virtual machine monitor. Although the claim’s plain language is decisive, we also disagree with Petitioner’s assertion that the ’697 patent’s specification describes only fingerprint creation outside the virtual machine monitor because, as Patent Owner explains, the specification describes fingerprint generation inside and outside the virtual machine monitor. See Sur-reply 1– 2; see id. at 2 (citing Ex. 1001, 6:65–7:2, 10:13–22). Claim 1’s plain language, however, only covers the latter. Last, Petitioner’s characterization of Patent Owner’s infringement allegations in the related district-court proceedings, even if correct, do not undermine the claim’s plain language.” slip op. at 9

Resp. 21–23 (explaining Petitioner’s mapping). Instead, Petitioner asserts that the at-issue claim language—“at the virtual machine monitor”—does not require “that each of the subsequently recited steps must be performed by or in the [virtual machine monitor],” but instead only requires “that the fingerprint is generated by the same decoy system that contains the [virtual machine monitor].” Reply 2. Petitioner argues that the intrinsic record supports its position because “[n]owhere in the ’697 Patent is there any teaching or suggestion that a [virtual machine monitor] creates a fingerprint/signature indicative of attack activity,” and instead, “[t]he ’697 Patent teaches that its signature generation engine is separate from the [virtual machine monitor].” Reply 2 (citing Ex. 1001, 8:12–19).

      “A patent claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter 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 subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) when in evidence, objective evidence of nonobviousness.3 Graham v.

Petitioner additionally contends a “person with less education but more relevant practical experience, depending on the nature of that experience and degree of exposure to liquid cooling systems for computer systems, could also qualify as a POSITA in the field of the ’681 patent.” Id.

Apart from arguing that the recited “parameter estimation unit” is limiting, Petitioner does not propose any id. Patent Owner does not respond to Petitioner’s contentions and also does not argue that any construction is necessary for the parameter estimation unit. See generally Prelim. Resp.

The body of each claim recites the elements of the recited “parameter estimation unit,” namely, “a signal processor for determining said channel transfer functions for each received signal” and “means . . . for providing uninterrupted estimates of the channel transfer function parameters on a real-time basis . . . .” The phrase “In a multi-user detection system in which interfering signals are purposely allowed to exist” provides additional context for the environment in which the parameter estimation unit is intended to operate. Whether the preamble is limiting is a question that we do not need to decide here, however. Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

More education can supplement practical experience and vice versa.” Pet. 5 (citation omitted). Patent Owner does not dispute Petitioner’s assertion. At this juncture, we adopt Petitioner’s definition. This definition appears to be consistent with what is reflected by the content of the applied prior art references. Cf. Okajima v.

      “In view of the parties’ agreement to adopt Patent Owner’s construction and the District Court’s persuasive analysis, we find that the “multi-user detector decision unit” terms in claims 1 and 10 are properly construed on the record before us to recite the functions “using decision criteria to determine a selected multi-user detector” for claim 1 and “select[ing] a multi-user detector based upon at least one threshold” for claim 10, both of which have the following corresponding structure: a MUD decision unit 220 (or, alternatively, decision logic unit 520) configured to perform one or more of the several decision algorithms (e.g., the BER/User, SINR/Symbol, Filtered SINR/Symbol, Detected Amount/Symbol, Correlation Matrix Ratio/User, Correlation Matrix Eigenvalues, Computational Complexity, Number of Bits, Number of Users, and other algorithms) disclosed at 8:12–18, 13:35–14:40, 15:3–21, 19:43– 48, 19:56–62, and 20:41–49 of the ’492 Patent.” slip op. at 12

      “a reasonable likelihood of success in establishing that Onggosanusi teaches or suggests these limitations. Petitioner does not rely on Egnor for these limitations. Therefore, Petitioner fails to show a reasonable likelihood of success in establishing that claims 1 and 10 would have been obvious over Onggosanusi and Egnor. Claims 2–9 and 11–16 depend from claims 1 and 10 respectively, and thus Petitioner likewise fails to show a reasonable likelihood of success that those dependent claims would have been obvious over Onggosanusi and Egnor. Therefore, we find that Petitioner fails to show a reasonable likelihood of success for Ground 1.” slip op. at 15

      “Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1367 (Fed. Cir. 2016) (“[T]he PTO is permitted, but never compelled, to institute an IPR proceeding.”). “Even when a petitioner demonstrates a reasonable likelihood of prevailing with respect to one or more claims, . . . institution of review remains discretionary.” Chevron Oronite Co. v. Infineum USA L.P., IPR2018-00923, Paper 9 at 10 (PTAB Nov. 7, 2018) (informative) (citing SAS Inst. v. Iancu, 138 S. Ct. 1348, 1356 (2018); Harmonic, 815 F.3d at 1367). Where a Petition presents a reasonable likelihood of success as to only a small number of the challenged claims, the Board has the discretion to decline to institute review, because instituting a full review on all challenged claims may be an inefficient use of the Board’s limited resources. See, e.g., Deeper, UAB v. Vexilar, Inc., IPR2018-01310, Paper 7 at 42–43 (PTAB Jan. 24, 2019) (informative) (denying institution where a petitioner demonstrated a reasonable likelihood of success on only two out of twenty- a petitioner demonstrated a reasonable likelihood of success on only two out of twenty claims). Of the eighteen challenged claims, we have found that Petitioner failed to establish a reasonable likelihood of success as to sixteen of those claims. This leaves a single independent claim (claim 17) and a single dependent claim (claim 18) remaining for consideration. Even were we to conclude that Petitioner had established a reasonable likelihood of success as to claims 17 and 18, this would leave at most two claims subject to a single ground upon which such a showing had been made, out of eighteen challenged claims. Based on the particular circumstances of this case, it would be inefficient for the Board to expend resources on a full review of all eighteen challenged claims, where Petitioner has failed to establish even a reasonable likelihood of success as to the vast majority of those claims. Accordingly, we need not, and do not, take any position as to Petitioner’s showing on Ground 2 but instead exercise our discretion to deny review.” slip op. at 21

      “We agree with Autoscribe’s argument that PayPal Express Checkout does not teach the “providing” steps of independent claim 1 and 25 and the “receiving” step of independent claim 15 for two reasons. First, as we explain in our claim construction analysis above, we decline to adopt M&A Ventures’s proposed construction of the “providing” and “receiving” steps as being limited temporally such that not providing the data token to the payer only occurs “during execution of the token retrieval function.” Instead, we construe the “providing” and “receiving” steps in accordance with their plain and ordinary meanings, which includes giving the negative limitation recited therein (i.e., not providing the data token to the payer) patentable weight, without limiting the occurrence of this negative limitation during execution of the token retrieval function. See supra Section II.A.1. With this construction in mind, step 4 of the PayPal Express Checkout flow run in the sandbox environment plainly sends the Payer ID, which M&A Ventures maps to the claimed “data token,” to the buyer. Ex. 1006, 17, 25–26; see also Pet. 64 (arguing PayPal’s Payer ID teaches the “non-sensitive electronic data token” (emphasis omitted)), 67 (arguing the same). Because PayPal sends the Payer ID to the buyer during the PayPal Express Checkout flow, PayPal provides the data token to the payer and, therefore, violates the negative limitation required by the “providing” and “receiving” steps.” slip op. at 31

      “page is in the visible area of the browser window.” Ex. 1001, 60:4–6. But nothing in the claim suggests that the determination is optional or that it need not ever occur. For example, the “in response to” limitation of claim 1 does not use the conjunction “if,” as was the case in Schulhauser. See 2016 WL 6277792, *3 (interpreting “triggering an alarm state if the electrocardiac signal data is not within the threshold electrocardiac criteria” such that “triggering an alarm state” only needs to be performed “if the electrocardiac signal data is not within the threshold electrocardiac criteria.”).7 In fact, the prior step (a) of claim 1 explicitly requires the determination, reciting: “(a) determining whether a predefined portion of the predefined area of the ad content display page is in the visible area of the browser window.” Ex. 1001, 60:1–3. As properly construed, the “in response to” language modifies the recited step of “causing a communication to be sent from the remote computing device to one or more dispatcher servers” such that the step must be “in response to a determination that the predefined portion of the predefined area of the ad content display page is in the visible area of the browser window.” Ex. 1001, 60:4–8. In other words, “causing a communication” is a required step of the method of claim 1.” slip op. at 8

      “Patent Owner argues that a person having ordinary skill in the art also would have had “experience in the internet advertising industry” and urges us to adopt the same formulation as we adopted in the final written decision in IPR2023-00953. Prelim. Resp. 4. We agree with Patent Owner that the person of ordinary skill in the art would have had such experience. Indeed, it is unclear how Petitioner’s proposal accounts for the types of problems encountered in the art or prior art solutions to those problems. See Daiichi Sankyo, 501 F.3d at 1256 (identifying these factors, among others, as “a guide to determining the level of ordinary skill in the art”). The difference between the parties’ proposals as to the person of ordinary skill in the art, however, is immaterial here.

When the event occurs, the system performs operation S203, otherwise, the system waits for the event to occur. In this instance, the event may include a user enter event or a scrolling event.”).
