      “communication device for multiplexing signals.” Ex. 1001, 12:2–3 (emphasis added). The language in the preamble does not support adopting Petitioner’s proposed interpretation of “multiplexing” to mean that “the connections may be used simultaneously or sequentially for combining multiple data paths into a single path,” because signals are being multiplexed, not connections or data paths.

      “show by a preponderance of the evidence that Yegoshin teaches or would have been understood to reasonably suggest “multiplexing signals” and that Bernard “includes or operates as a multiplexer for combining the data packets.” See Pet. 32–40. Because Petitioner does not show multiplexing signals in any of the asserted references, Petitioner does not show by a preponderance of the evidence that its proposed combination of Yegoshin, Bernard, Johnston, and Preiss would have rendered obvious “[a]n IP-enabled communication device for multiplexing signals,” as recited by claim 1. Also, because Petitioner fails to show Yegoshin teaches or would have been understood to reasonably suggest multiplexed signals and fails to show that Bernard “includes or operates as a multiplexer for combining the data packets,” Petitioner’s asserted motivation to modify Yegoshin in view of Bernard for “multiplexing signals” lacks rational underpinning. Weighing the underlying factual determinations, a preponderance of the evidence does not persuade us that claim 1 of the ’075 patent is unpatentable over Yegoshin, Bernard, Johnston, and Preiss.

      “B. Level of Ordinary Skill in the Art In determining the level of skill in the art, we consider the type of problems encountered in the art, the prior art solutions to those problems, the rapidity with which innovations are made, the sophistication of the technology, and the educational level of active workers in the field. Custom Accessories, Inc. v. Jeffrey-Allan Indus. Inc., 807 F.2d 955, 962 (Fed. Cir. 1986); Orthopedic Equip. Co. v. U.S., 702 F.2d 1005, 1011 (Fed. Cir. 1983). Petitioner contends the following assessment in connection with a person of ordinary skill in the art: The Challenged Claims pertain to a method of recovering geothermal heat. However, “[m]any of the techniques are derived from oil and gas industry.” EX1001 at 4:23-24. Accordingly, here, a person of ordinary skill in the art (“POSITA”) is a person with a Bachelor’s degree, Master’s degree, and/or Ph.D. in Chemical Engineering, Petroleum Engineering, Energy Resource Engineering, or the like, or at least five years of experience engineering, drilling, and constructing wells. Furthermore, a person with less formal education but more experience, or more formal education but less experience, could also have met the relevant standard for a POSITA. Pet. 16–17 (citing Ex. 1004 ¶¶ 34–36). Patent Owner does not offer its own assessment of a POSITA. For purpose of this Decision, we adopt Petitioner’s assessment.” slip op. at 9

Patent Owner further submits that “[u]nder Rule 104(b)(3),[14] Petitioner had an obligation to provide a construction of claim element 9c that includes both the claimed function and the specific portions of the specification that describe the structure, material, or acts corresponding to each claimed function.” Id. We agree with Patent Owner that the term “means for” when appearing in a claim triggers a rebuttable presumption that treatment under § 112 applies. On the record before us, however, Petitioner has not explained why the noted presumption has been rebutted or does not apply, and has not provided a construction of the pertinent “means for” term in the Petition in contradiction to the requirements of 37 C.F.R. § 104(b)(3).” slip op. at 10

      “While it is certainly the case that “a prior art reference is relevant for all that it teaches to those of ordinary skill in the art,” see In re Fritch, 972 F.2d 1260, 1264-65 (Fed. Cir. 1992), it is incumbent on a petitioner, in advancing a permissible theory of obviousness, to explain why a skilled artisan would recognize to pick and choose certain aspects of a reference and combine them with other aspects of the reference, particularly so where the reference itself does not suggest such combination. See In re Hedges, 783 F.2d 1038, 1041 (Fed. Cir. 1986) (“It 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” ) (citation and inner quotes omitted). Here, Petitioner’s oscillation between different embodiments of Rinaldi in an attempt to reach the requirements of claim 1 is not adequately explained, and more closely resembles impermissible hindsight. See Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1367 (Fed. Cir. 2017). (“[W]e cannot allow hindsight bias to be the thread that stitches together prior art patches into something that is the claimed invention.”). In sum, we determine that Petitioner has not shown a reasonable likelihood of prevailing in its assertion that claim 1 is unpatentable as a part of Petitioner’s proposed Ground 1.” slip op. at 18

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “B. Level of Ordinary Skill in the Art Petitioner, citing Dr. Bims’s declaration, asserts that, “[a] person of ordinary skill in the art (“POSITA”) in the subject matter of the ’817 patent would have had a master’s degree in electrical engineering, computer engineering, or computer science, or equivalent and at least three years of experience in the field of telecommunications or wireless systems,” and that “[a]dditional education might compensate for less experience, and vice-versa.” Pet. 10–11 (citing Ex. 1002 ¶ 22). Patent Owner asserts that one of ordinary skill would have had “a bachelor’s degree in electrical engineering, computer engineering, or computer science with (1) at least three years of experience in the field of telecommunications or wireless systems; and/or (2) an advanced degree in field of telecommunications or wireless systems.” Prelim. Resp. 16. We do not discern a meaningful difference between the two parties proposals. Petitioner’s proposal appears consistent with the problems and solutions in the ’817 patent and prior art of record and is supported by expert testimony. We note, however, that the open-ended language “at least” expands the range of experience indefinitely with no upper bound. Upon this preliminary record and for the purposes of institution, we adopt Petitioner’s definition of the level of skill with the exception that we delete the words “at least.”” slip op. at 9

      “C. Claim Construction Neither party makes a claim construction proposal or indicates that any claim requires construction. Pet. 11; see generally Prelim. Resp. We note that an argument was raised that presents an implicit construction question regarding whether a flag which “only identifies if encryption [is] ‘on’ or ‘off’” (Prelim. Resp. 24) teaches or suggests “an encryption scheme identifier that identifies an encryption scheme used by the UE to encrypt the subscription identifier in the SUCI” (as recited in limitation 1d of claim 1 and identically in claims 9, 10, and 15). We address that argument below, in Sections II.D.3.c.ii and iii of this Decision. With that exception, we do not discern that any claim terms require construction at this point in the proceeding for the purpose of institution. See Nidec Motor Corp. v.

    • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportReference is prior artDecided for petitioner

      “i. Nair Provisional’s Support for a Claim in Nair Patent Owner argues that the Petition is deficient because it does not show that the disclosure in the Nair Provisional supports at least one claim in Nair, even though Nair is subject to the AIA and Patent Owner concedes that the Board’s precedential opinion in Penumbra concludes we do not need to make such a determination regarding support for at least one claim to reach a prior art determination under the AIA. Prelim. Resp. 23–24 n.6; Penumbra, 2023) (precedential). Following that precedent, we decline to require a showing of support in the Nair Provisional for at least one claim in Nair and instead only require that the ministerial requirements for claiming priority were met. See Penumbra, Paper 34 at 32–33. Petitioner argues that the “ministerial requirements” described in Penumbra have been met. Pet. 4–5 (noting that Nair contains a priority claim to the Nair Provisional, was filed within 12 months of the Nair Provisional, and includes a common inventor). Patent Owner does not contest that these requirements have been met, and upon our examination, we agree that they appear to have been met. Ex. 1004, codes (22), (60), (72); Ex. 1008, 1, 4, 38. Thus, on the present record and for the purposes of institution, the disclosures of Nair are prior art, to the extent that the relied-upon disclosures are included in the Nair Provisional. ii. Nair Provisional’s Date for Cited Portions of Nair Patent Owner also argues that the Petition relies on material in Nair that was added after the filing of the Nair Provisional, and that this material cannot be properly relied on as prior art. Prelim. Resp. 19–23. We address these specific arguments regarding material Petitioner references from Nair (and the Nair Provisional) below, in our analysis with respect to the respective limitations of claim 1 these citations relate to.” slip op. at 15

      “Further, we find the testimony of Patent Owner’s declarant more persuasive based at least on his consideration of Swenson as a whole and his more detailed analysis and explanations. For example, Patent Owner’s declarant explains in detail why, “[i]n the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets:” Furthermore, Swenson discloses that the steering device 130 “sends an ICAP request message 516 comprising [a] HTTP GET request header and a portion of the [HTTP] response payload to the network controller 140, which inspects the message to determine whether to monitor the flow or optimize the video.” Ex. 1007 [0065]. In the context of a HTTP GET request and response, as disclosed in Swenson, the message does not constitute a single packet but a flow of packets. The reference to a HTTP request and response “header” and “payload” are thus not references to the header and payload of a packet. A POSA would know that despite common parlance references to “HTTP packets,” HTTP does not pertain to individual packets, whereas packet transmission is governed by the TCP protocol. HTTP utilizes TCP to exchange data such that information may be used by an end user (e.g., a video or audio stream). Even assuming that Swenson’s controller were analyzing the header and payload of an HTTP request/response, a POSA would understand that this analysis is not at the packet but at the flow level and thus does not constitute deep packet inspection. Ex. 2025 ¶ 69. Petitioner’s declarant merely responds by reiterating what was previously stated: Swenson is explicit in stating that its inspection techniques include inspection of “a portion of the [HTTP] response payload.” . . . A POSA would have understood the analysis of the “response payload” to be DPI by a DPI-capable controller, as DPI refers to monitoring the payload of a packet.” slip op. at 15

Additional education may substitute for experience, and significant work experience may substitute for formal education. Pet. 6 (citing Ex. 1002 ¶¶ 115–120). Patent Owner does not dispute Petitioner’s proposed level of skill in the art, which is consistent with the prior art references asserted by Petitioner. Okajima v. Bourdeau, 261 F.3d 1350, 1354–55 (Fed. Cir. 2001) (stating that the applied prior art may reflect an appropriate level of skill).

      “Since the parties apply what they contend is the plain and ordinary meaning of the claim terms in their briefs, and have stipulated in the Cox case that the plain and ordinary meaning applies, and Patent Owner argues that the district court’s construction in the Charter case is the plain and ordinary meaning, there is no controversy concerning claim terms that we need to resolve in this Decision. Pet. 6; Prelim. Resp. 10; Ex. 1005, 104–105; Ex. 2001, 2. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). At this stage of the proceeding, therefore, we apply the plain and ordinary meaning to the claim terms consistent with their ordinary and customary meaning under 37 C.F.R. § 42.100(b). We note, however, that Patent Owner seems to consider the court’s construction in the Charter case to require that the claimed “probe” must be of a type that can be compared with a reference signal. Prelim. Resp. 10. We question whether all of the different types of probes mentioned and claimed in the ’690 patent would require comparison with a reference signal. See, e.g., Ex. 1001, 2:7–19. However, this is a matter best resolved, if necessary, on a full record at trial.” slip op. at 14

      “Prelim. Resp. 23 (citing Ex. 1013, 37) (annotated in red by Patent Owner). IEEE-802.16’s Table 5 shows that the CID is a field of a generic MAC header. Petitioner does not show sufficiently that the CID, located in the header, specifies content payload of a MAC message, as required by limitation 1A. Petitioner alternatively relies on IEEE-802.16’s ranging code index that it contends is another example of data that is in a ranging request parameter and is used for the ranging response payload. Pet. 15 (citing Ex. 1013, 49–51, 204–213, 576–579, 665–66; Ex. 1002 ¶ 149). Patent Owner asserts that the portions of IEEE-802.16 that Petitioner cites do not disclose that the ranging code index is sent as part of a ranging request message. Prelim. Resp. 25. Although the parts of IEEE-802.16 that Petitioner cites disclose that the ranging code index is sent from the SS to the BS and is included in a ranging response (Ex. 1013, 49–51, 204–213, 576–579, 665–66), the cited parts do not disclose that the SS sends the ranging code index to the BS in a ranging request. Consequently, Petitioner has not established that IEEE- 802.16 anticipates a ranging code index that is a parameter of a ranging request specifying the content payload of the ranging response corresponding to limitation 1A. For the foregoing reasons, on this record, we determine that Petitioner has not shown a reasonable likelihood to prevail in showing that claim 1 is anticipated by IEEE 802.16.” slip op. at 18

      “persuaded on the current record that Patent Owner provides sufficient evidence to establish the failure of others. Patent Owner makes much of Broadcom and CableLabs allegedly failing to “realize the possibility of remote spectrum monitoring” prior to the ’008 patent. See Prelim. Resp. 50–52. The mere failure to “realize the possibility” of a certain technique or device, however, is not sufficient to show the failure of others. Rather, the failure of others as an indicium of nonobviousness generally 8 DOCSIS refers to “Data Over Cable System Interface Specification.” Ex. 1011, 1:42–43. relates to situations where others failed while attempting to address a particular problem. See In re Cyclobenzaprine Hydrochloride Extended- Release Capsule Pat. Litig., 676 F.3d 1063, 1081 (Fed. Cir. 2012) (“Evidence that others tried but failed to develop a claimed invention may carry significant weight in an obviousness inquiry. . . .

Resp. 10. Petitioner contends this construction is consistent with the ordinary and customary meaning of the claim language. Pet. 25.
