    “On remand, the Board is to determine “[w]hether the alleged inconsistency in [Petitioner’s] treatment of map images compared to other first/second versions of claim elements supports rejecting [Petitioner’s] theory on claim-construction or other merits grounds is a matter for the Board to consider in the first instance on remand, constrained by any relevantly similar now-final findings of fact and conclusions of law in the ’020 PGR and related proceedings” (CAFC Dec. 16). Thus, the two issues on remand are (1) the construction of the second map image and (2) whether A3UM teaches or suggests the claimed “second map image” under that construction.” slip op. at 10

    “c. Analysis We agree with Petitioner that the “second map image” should be construed as the map image in the second person view. Reply 5. Under Petitioner’s proposed construction, the terms “first” and “second” identify which person view that the map image is within. Id. The map image’s connection to the person view is important to how the user interacts with the interface because selecting the map image in one view does something different than selecting the map image in another, as recited in claims 14 and 46.” slip op. at 12

    “Here, we disagree with Patent Owner’s argument because it is based on the premise that the second map image is different from the first in a way that is not reflected in the claims. See Section II.C.3 supra. Even if “the claims consistently use the terms ‘first’ and ‘second’ to refer to separate and distinct elements,” A3UM’s first and second map images are separate and distinct elements for at least the reason they are included in separate and distinct views in the interface. See Pet. 63; Reply 5. As discussed in Section II.C.3, the second map image is the map image in the second person view. Here, Petitioner sufficiently shows that A3UM provides the same functionality for each person, including displaying the person in the Faces view with their name within A3UM’s overall user interface. See Pet. 62 (citing Ex. 1003, ¶215; Ex. 1005, 418–420). Patent Owner does not dispute this. See PO Resp.; Sur-reply. For the same reasons why A3UM teaches the “first map image” with respect to a first person view recited in claims 1 and 31, Petitioner has shown that A3UM also teaches the “second map image” in the second person view. See FWD 53–56. In sum, Patent Owner’s arguments are unpersuasive because they are based on an incorrect claim construction, and Petitioner has shown that claims 13 and 45 are unpatentable. 5. Claims 14–16 and 46–48 Apart from the arguments analyzed above, Patent Owner does not present separate arguments directed to the subject matter of claims 14–16 burden to show that the challenged claims are unpatentable. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). We have reviewed Petitioner’s arguments and evidence submitted in connection with the remaining limitations and find them persuasive as they are consistent with and supported by the evidence of record. See Pet. 63–64. Thus, Petitioner has shown that claims 14–16 and 46–48 are unpatentable over A3UM.” slip op. at 14

    “of Choi to support its argument that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed. See Pet. 61–62. With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape. See Ex. 1002 ¶ 197.

This is due to the fact that the claims (without limit) encompass any inhibition of any one of the various types of IL-15 signaling and various versions of the receptor, and even implicate other compounds that act on different targets but which inhibit the IL-15 signaling pathway.

  • Strike new argumentNew argument disregardedDecided for patent owner

    “We agree with Patent Owner. The Petition is required to identify “[h]ow the challenged claim is to be construed.” 37 C.F.R. § 42.104(b)(3). Petitioner argued in the Petition that “as properly construed, the claimed ‘first parameter,’ ‘second parameter,’ ‘third parameter,’ and ‘fourth parameter’ are four different parameters.” Pet. 17–18. In the Institution Decision, Petitioner prevailed on that point and “we agree[d] with Petitioner that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels.” Dec. 14. Patent Owner “relie[d] on the Board’s construction ‘that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels,’” and proposed distinct parameters in the Specification that it alleges are examples of second and third parameters, albeit not the same two parameters proposed by Petitioner. PO Resp. 9, 29. Petitioner now proposes new constructions for the second and third parameters that would limit those parameters to the two examples it advanced in the Petition and improperly supports these new constructions with new expert testimony and an exhibit from the prosecution of a later patent. Reply 20–25; Ex. 1040 ¶¶ 20–29; Ex. 1038. See also Consolidated Trial Practice Guide (“TPG”)10 73 (“Petitioner may not submit new evidence or argument in reply that it could have presented earlier, e.g. to make out a prima facie case of unpatentability.”). As Patent Owner observes (Sur-reply 10 Available at https://www.uspto.gov/TrialPracticeGuideConsolidated. 21), it has no opportunity to introduce rebuttal evidence contesting the new constructions. See TPG 73–74 (Nov. 2019) (“The sur-reply may not be accompanied by new evidence other than deposition transcripts of the crossexamination of any reply witness. Sur-replies should only respond to arguments made in reply briefs, comment on reply declaration testimony, or point to cross-examination testimony.”). We agree with Patent Owner that it would be unfair to consider Petitioner’s new construction. See 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in the corresponding opposition, patent owner preliminary response, patent owner response, or decision on institution.”). Thus, Petitioner has forfeited its new claim construction arguments and they will not be considered. See TPG 74 (“While replies and sur-replies can help crystalize issues for decision, a reply or sur-reply that raises a new issue or belatedly presents evidence may not be considered.”). Moreover, these arguments would be unpersuasive even if considered. Petitioner has, at most, cited description in the Specification to show that its identified second and third parameters are examples corresponding to the recited second and third parameters. Ex. 1005 ¶¶ 84–95. This description does not define the second and third parameters nor purport to exclude from the claims any parameter that would otherwise meet the language of the claims. The prosecution history to which Petitioner cites, that of a child application, took place after the prosecution of the ’466 patent and thus, does not constitute a definition or disclaimer of subject matter for claims of the ’466 patent. In any case, the brief argument in the cited response to office action, that “[i]n the algorithm, the first value is provided by the wireless network for each of a plurality of buffers where the buffer having the second value above a threshold transmits data first,” does not define the second and third parameters, disavow any values from those parameters, or even discuss the third parameter. Ex. 1038, 12. Petitioner’s extrinsic evidence, Dr. Akl’s testimony, does little more than repeat the arguments in the Reply and, thus, is of little value. Ex. 1040 ¶¶ 20–29. In sum, we maintain our construction that the second and third parameters are separate and different parameters, and not different instances of the same parameter for separate channels. Under this construction, RAAUq” and RAAUq’, respectively, could potentially be second and third parameters, as could RAAUq’ and RAAUq”, respectively, as long as they satisfy the rest of the pertinent language of the challenged claims.” slip op. at 15

    “production, we still would find that a skilled artisan would not have been able to ascertain from the disclosure in the ’421 application that RAAUq’ could take values less than zero. Instead, even if we were to credit Dr. Lomp’s testimony, to conclude that RAAUq’ can take negative values, a skilled artisan would need to program computer software to simulate the ’421 application’s algorithm and correctly choose starting parameters and other context variables without guidance from the description in the ’421 application. This case is similar to that in New Railhead, where the written description was insufficient because “one of ordinary skill in the art must first make the patented invention before he can ascertain the claimed features of that invention.” 298 F.3d at 1295. This case also is similar to Los Angeles Biomedical Research Institute, in which an application’s written description was insufficient because assumptions and starting variables were not knowable from the disclosure in the application. 849 F.3d at 1058. Thus, even if we were to conclude that Patent Owner has met its burden of production, a preponderance of the evidence shows that the ’421 application does not provide written description support for Alternative A. In sum, we conclude that the ’421 application does not provide written description support for the challenged claims and that, therefore, Speight is prior art to the challenged claims.” slip op. at 41

    “vi. Proposed Combination of Ellison and Muir Petitioner contends that Ellison discloses “an isolated execution architecture that improves security in a computer system or platform by implementing several levels of hierarchy and normal and isolation execution modes for the operating system and processor.” Pet. 46–47 (citing Ex. 1006, 1:12–15, 2:40–61, Fig. 1). Although Petitioner acknowledges that Ellison “does not reveal details of [] a system or transaction between multiple parties,” Petitioner relies on Muir for such teaching. Id. at 47. According to Petitioner, a POSITA looking to implement Ellison’s isolated execution architecture in a computer with multiple devices “would have looked to Muir’s teachings to implement a secure electronic transaction between two parties,” because “both Ellison and Muir are related to providing improved security for transactions involving keys using cryptographic techniques.” Id. at 48 (citing Ex. 1006, 1:38–51; Ex. 1008, 7, 8, 11; Ex. 1003 ¶ 66).

We credit the testimony of Dr. Black as sufficient support for Petitioner’s contention, when he explains, “a POSITA would have viewed extension of Ellison’s system to include the multi-party transactions described by Muir to have been a natural and obvious extension,” wherein a “a POSITA would have been motivated to enable such multi-party transaction [] in Ellison’s system to increase the functionality and usefulness of Ellison’s system.” See Ex. 1003 ¶ 69.

    “term “placing” requires more than a theoretical placing or planning to place as part of an analytical solution. Turning first to the claim language, we agree with Petitioner that the language of the independent claims is consistent with “placement” occurring after and separately from the analytical evaluation process. See Pet. Reply 3. For example, claim 1 is directed to a system for “determining placement of source computer systems on target systems,” the system configured to “determine a placement” by employing operations to “evaluate compatibility.” Ex. 1001, 40:2–4, 40:8– 36. The second “evaluate compatibility” operation is “to determine if the specific source system can be placed with those other source systems on the specific target system,” which suggests that what is being evaluated is whether the source system can be actually placed (e.g., moved or transferred) to the target system. Id. at 40:18–27 (emphasis added). Similarly, the third “evaluate compatibility” operation involves “evaluating the impact on resource utilization of the specific target system of placing the specific source system on the specific target system,” which suggests that what is being evaluated is the impact on resource utilization once the source system is actually moved or transferred to the target. Id. at 40:28–32 (emphasis added). Additionally, the claim states that, based on the “evaluate” operations, the claimed system “determine[s]” a placement, not that it executes the placement. Id. at 40:8–11. The actual placement seemingly occurs after the final claimed operation of “issu[ing] instructions to place” the source system(s) on to the target system “in accordance with the determined placement.” Id. at 40:37–39. Independent claims 32 and 63 include similar language. Id. at 42:36–43:3, 45:1–46:19.

    “As noted above, the claim language requires evaluating compatibility between a specific source system and one or more other source systems “already placed” on the target system. Paragraph 82 does not disclose the evaluation of compatibility of a source system and another source system as part of the “forward consolidation.” Additionally, paragraph 82 does not disclose that “existing target systems 16” have source systems “already placed” on them. Thus, paragraph 82 does not provide the level of detail recited in the limitation under either party’s definition of “placed.” In addition, as noted above, we have interpreted “placed” to require an actual placement rather than merely “planning to place” or a theoretical placement. See § II.A.2, supra. Therefore, even if the “existing target system 16” had theoretical or hypothetical systems added to it as part of the consolidation analysis, those would not be systems that are “already placed” on the target system.” slip op. at 34

See Realtime Data, 912 F.3d at 1375 (noting that we need only construe “only those terms that . . . are in controversy”). Ex. 1003 ¶ 92).

Nor can the language of claim 1 reasonably be read to exclude combining more than one ceiling tile with the microphone array. Where claim 1 assigns specific properties to a ceiling tile, it does so expressly, reciting “the ceiling tile being sized and shaped to be mountable in a drop ceiling in place of at least one of a plurality of ceiling tiles included in the drop ceiling.” Thus, the plain language of claim 1 requires at least one ceiling tile combined in some way with a beamforming microphone array, and each ceiling tile (if there is more than one) is a particular size and shape.” slip op. at 13

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
