“For purposes of institution, we find sufficient Dr. Darrell’s testimony that a person of ordinary skill in the art would have been motivated to combine Choe and Workman because Workman discloses predictive models to identify the horizon line (Ex. 1003 ¶ 146), and additionally, because using Workman’s model to identify the horizon line would have been combining known elements (CNNs and annotation for camera calibration) according to known methods to yield predictable results and used known techniques (CNNs) to improve similar devices in the same way. Pet. 48 (citing Ex. 1003 ¶ 150). We find sufficient for institution Dr. Darrell’s testimony that because these models were well known, a person of skill in the art would have had a reasonable expectation of success in combining the teachings of Choe and Workman to achieve the method of claim 1. Id. at 49 (citing Ex. 1003 ¶ 150). We have reviewed Mr. Andrews’s testimony to the contrary (Ex. 2003 ¶¶ 71–80) but, at this stage, do not find it persuasive. For example, to the extent Patent Owner and Mr. Andrews assert that Choe does not identify any “shortcomings” that would motivate a POSITA to look for a better approach like that of Workman (see Prelim. Resp. 29; Ex. 2003 ¶ 74), we note that it is “not necessary to show that a combination is ‘the best option, only that it be a suitable option,’” and “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill,” Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (citations omitted).

Patent Owner disagrees with Petitioner’s definition and asserts that a POSITA “would have a bachelor’s degree in engineering or computer science with one- or two-years training and/or experience in design of software for camera/sensor systems in the automotive industry.” Prelim. Resp. 12 (citing Ex. 2003 (Declaration of Scott Andrews) ¶ 35). We determine that no express finding is necessary, on the present record, and that the level of ordinary skill in the art is reflected by the prior art of record. See Okajima v.

The difference in how each party characterizes a POSITA’s work experience does not change our analysis or conclusions based on the present record.

“B. Merits 1. Level of Ordinary Skill in the Art According to the Petition, Here, a Person of Ordinary Skill in the Art (“POSITA”) at the time of the claimed invention would have a bachelor’s or equivalent degree in computer science or a related field and at least 2 years of experience in multimedia processing or delivery using internet protocols. . . . A person with less formal education but more experience, or more formal education but less experience, could also meet the standard. Pet. 19 (citing Ex. 1007 ¶¶ 68–69). Patent Owner provides a different definition: A person of ordinary skill in the art at the time of the inventions in the ‘002 Patent would have had a bachelor’s degree in computer science or a related field, and at least two years of experience working in the field of software systems used in generating and broadcasting multimedia streams. An individual with less technical education but more experience, or vice versa, could also qualify as a person of ordinary skill in the art. Prelim. Resp. 12 (citing Ex. 2006 ¶ 59) (emphasis added).

“There is no dispute that (1) Avellan’s user initiates the request and eventually receives the stream and (2) gateway server 134 receives a request for a media stream for playback on a broadcast channel. See id. at 32–39; Pet. 22. The issue here is whether claim 1 requires that the recited “content provider” originates the request. We agree with Petitioner that claim 1 does not require this. Prelim. Reply 7. Apart from being received from the content provider, claim 1 does not limit the request’s origin in any way. Rather, claim 1 only requires that the request is received from the content provider. Ex. 1001, 14:51–54. Claim 1 recites “comprising” in the preamble of the method (id. at 14:50), which is a encompasses user-originated requests that are received from other entities. With this understanding of the claim, we preliminarily agree with Petitioner that Avellan discloses limitation 1a through its communication path from network 150 to user computers 1041–104n via gateway platforms 1301–130n. Pet. 22. That is, Avellan’s gateway platform 134 receives a request for at least one media stream, and claim 1 does not exclude user-originated requests. See id. We agree that the content can be video from CNN, BBC, ESPN, or other live-streaming television feeds. Id. at 24 (citing Ex. 1003, 8:18–21). Thus, at this stage and on this record, we agree with Petitioner that Avellan discloses limitation 1a. See id. at 22. ii. Remaining Limitations Apart from the arguments discussed above, Patent Owner does not present arguments specifically directed to the other limitations of claim 1. See Prelim. Resp. We determine that Petitioner’s arguments made in connection with those limitations are sufficient at this stage and on this record. Pet. 24–32. We agree with Petitioner that Avellan teaches obtaining content from the networks 150 and 152, as recited in 1b; rendering a webpage by a browser at gateway 134, as recited in 1c; generating the screen captures at gateway 134, as recited in 1d; and assembling and providing the media stream when gateway server 134 compresses the image or video format and sends it to the browser 106, as recited in 1e and 1f. Id. at 24–29. Petitioner has provided a sufficient rationale at this stage why a method with the subject matter recited in lg and 1h would have been obvious. Id. at 29– 32. Conclusion At this stage and on this record, it is reasonably likely that Petitioner would prevail in showing that claim 1 is unpatentable as obvious over Avellan.

Id. (citing Ex. 1004 ¶¶ 108–109; Ex. 1010 ¶ 419). Mr. Kasdorf’s declaration testimony is nearly verbatim to the Petition and similarly provides no indication as to what in CryptoKube constitutes a “mining processor” other than his conclusory opinion that one of ordinary skill in the art “would have understood that to mine bitcoin, the mining processors need to be connected to a network interface and adapted to mine transactions associated with the 19 We note that Mr. Kasdorf’s reliance on Kheterpal is limited to Kheterpal’s background discussion regarding the Bitcoin protocol inasmuch as it “defines a system in which the creation and distribution of the bitcoin cryptocurrency is governed by consensus among a peer-to-peer network” and includes “a public ledger in which new transactions are verified and recorded by members of the network via cryptography.” Ex. 1010 ¶ 4.

“Petitioner’s contention that “a combination of an ASIC chip and a controller would meet the ‘mining processor’ limitation” (Pet. Reply 11 (citing Ex. 1036 ¶ 21)) is an improper new argument. In determining whether an argument is a proper argument in reply, we look to see if the Reply argument is responsive to an argument from Patent Owner and expands on a position in the Petition. See Rembrandt Diagnostics, LP v. Alere, Inc., 76 F.4th 1376, 1384 (Fed. Cir. 2023) (“[W]e have held that a reply may be proper if it is responsive and simply expands on previously raised arguments.”). Or, if Petitioner relies on previously unidentified disclosure “to make a meaningfully distinct contention.” Id. at 1383 (“[W]e held that a petitioner who asserted in its reply previously unidentified prior-art disclosures ‘to make a meaningfully distinct contention’ was impermissibly raising a new theory of unpatentability.”). We find that Petitioner’s argument in reply is closer to the later situation. Here Petitioner does not expand on a position from the Petition that Patent Owner criticizes based on the merits of the contentions.

“B. Level of Ordinary Skill in the Art Petitioner asserts that a person of ordinary skill in the art [“POSITA”] at the critical time “would have had a bachelor’s degree in electrical engineering, mechanical engineering, computer science, or a similar field and two years of experience related to electronic consumer product design [and the] POSITA could have also obtained similar knowledge and experience through other means.” Pet. 6 (citing Ex. 1003 ¶ 31). Patent Owner states that it would require experience with electro-mechanical control systems rather than electronic consumer product design. PO Resp. 3. Because Petitioner provides for “similar knowledge and experience through other means,” we do not discern any meaningful distinction. Thus, we adopt Petitioner’s proposed level of ordinary skill, as it appears to be consistent with the specification of the ’830 patent and the prior art of record.” slip op. at 7

“Determining whether a limitation that does not use the term “means” invokes § 112, paragraph 6, involves a three-part inquiry: (1) there is a generic placeholder that substitutes for the term “means”; (2) the generic placeholder is modified by functional language; and (3) the limitation does not include the structure, material, or acts necessary to perform the function in question without need to resort to other portions of the specification or extrinsic evidence for an adequate understanding of the structure. See Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1349 (Fed. Cir. 2015); Tri-Med, Inc. v. Stryker Corp., 514 F.3d 1256, 1259–60 (Fed. Cir. 2008); Rodime PLC v.

“Limitation [1b] With respect to limitation [1b], a “moveable component,” Petitioner argues that it should be construed as a means (component) having a function (moveable) that corresponds to a structure (a moving weight). Pet. 7. Petitioner argues that “essentially any physical component can perform the function of being moved,” references different types of structure as the moving components in the ’830 patent, and concludes that therefore the term has no definite structure. Pet. Reply 2 (citing Ex. 1001, Figs. 4A–4G, 14, 15–17). Patent Owner argues for a non-means-plus-function construction of a component that “is capable of being moved.” PO Resp. 7–8 (citing Ex. 2008 ¶ 55). Patent Owner argues, and Petitioner agrees, that “there is likely no material difference between” the parties’ proffered constructions such that construction is necessary. Id. at 8; Pet. Reply 7. We agree, because Petitioner has shown, and Patent Owner does not contest, that the prior art teaches such a component under either construction. Infra § II(D)(2)(a). Because Petitioner’s assertions and our determination would be unaffected by its proposed construction, we need not construe this term. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Cir. 2017). The General Electric decision cited by Petitioner does not hold otherwise. In General Electric, the Federal Circuit considered an obviousness challenge based on combining disclosures from multiple references. See Gen. Elec., 983 F.3d at 1339–40, 1344–52. The Federal Circuit criticized the Board for dissecting an embodiment disclosed in the primary reference into a collection of “individual elements” and requiring the patent challenger to “re-do the work already done” regarding that embodiment in the primary reference. Id. at 1351–52. The Federal Circuit did not consider an obviousness challenge based on combining multiple embodiments from a single reference. See id. at 1344–52.

“B. Level of Ordinary Skill in the Art Factors pertinent to determining the level of ordinary skill in the art include (1) the educational level of the inventor; (2) the type of problems encountered in the art; (3) prior-art solutions to those problems; (4) the rapidity with which innovations are made; (5) the sophistication of the technology; and (6) the educational level of workers active in the field. Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983). Not all factors may exist in every case, and one or more of these or other factors may predominate in a particular case. Id. These factors are not exhaustive, but merely a guide to determining the level of ordinary skill in the art. Daiichi Sankyo Co. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir. 2007). Moreover, the prior art itself may reflect an appropriate skill level. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Petitioner asserts that a person of ordinary skill in the art at the time of the alleged invention “would have had a bachelor’s degree in electrical engineering, mechanical engineering, computer science, or a similar field and two years of experience related to electronic consumer product design.” 3 The parties do not provide evidence or argument regarding objective indicia of nonobviousness. See, e.g., Pet. 9–93; Resp. 18–66. Pet. 6. Petitioner also asserts that an ordinarily skilled artisan “could have also obtained similar knowledge and experience through other means.” Id. Dr. Wolfe’s testimony supports Petitioner’s assertions. See Ex. 1003 ¶ 30. Patent Owner asserts that a person of ordinary skill in the art at the time of the alleged invention “would have had (1) a bachelor’s degree in electrical engineering, mechanical engineering, or a comparable field of study, and (2) at least two years of professional experience with electro-mechanical control systems, or other similarly relevant industry experience.” Resp. 3.

Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999); see Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017). Above, we discussed issues concerning the “component” limitations in claims 1, 3, and 4 and an ambiguity in claim 4. See supra §§ III.C.4(c), III.C.5(c), III.C.6(c), III.C.7(c), III.C.8(c), III.C.9. We determine that no other claim language requires a discussion of scope or an explicit construction to decide whether Petitioner satisfies the “preponderance of the evidence” standard for proving unpatentability. D. Alleged Obviousness over Fukumoto: Claims 1–3, 7–9, and 17 Petitioner contends that claims 1–3, 7–9, and 17 are unpatentable under § 103(a) because the claims would have been obvious over Fukumoto.

For the reasons explained below, we agree with Petitioner that claims 1, 2, 7, and 17 are unpatentable under § 103(a) because the claims would have been obvious over Fukumoto but disagree that claims 3, 8, and 9 are unpatentable based on Fukumoto.” slip op. at 44

“2. MEANS-PLUS-FUNCTION CLAIMING The patent statute provides that “[a]n element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.” 35 U.S.C. § 112 ¶ 6 (2006). The absence of the word “means” in a claim limitation creates a rebuttable presumption that § 112’s means-plus-function provision does not apply. Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part). When a claim limitation lacks the word “means,” a party may rebut the presumption that § 112’s means-plus-function provision does not apply by demonstrating that “the claim term fails to ‘recite[] sufficiently definite structure’ or else recites ‘function without reciting sufficient structure for performing that function.’” Williamson, 792 F.3d at 1348 (alteration by the court) (quoting Watts v. XL Sys., Inc., 232 F.3d 877, 880 (Fed. Cir. 2000)). Construing a means-plus-function limitation involves two steps: first, identify the claimed function or functions; and second, determine what structure, if any, disclosed in the patent’s specification corresponds to the claimed function or functions. Williamson, 792 F.3d at 1351; see Medtronic, Inc. v. Advanced Cardiovascular Sys., Inc., 248 F.3d 1303, 1311 (Fed. Cir. 2001). For the second step, a person of ordinary skill in the art must “recognize the structure in the specification and associate it with the corresponding function in the claim.” All-Voice Computing PLC v. Nuance Commc’ns, Inc., 504 F.3d 1236, 1241 (Fed. Cir. 2007). The “duty to link or associate structure to function is the quid pro quo for the convenience” of using means-plus-function claiming. B.

“limitations that require specific connections between MIMO transceivers and arrays and a relationship between MIMO transceivers and beams.” Pet. 41. Petitioner contends that “Trigui teaches that each of the two modems (MIMO transceiver) would be connected to one of the two beams from each of the two arrays,” resulting in the interconnection requirements recited in the two “wherein” clauses of limitation [1b]. Id. at 41–42. Petitioner concludes that a person having ordinary skill in the art would have found the interconnection recitations of limitation [1b] obvious. Id. at 48–50; see id. at 48 (providing an annotated version of Trigui’s Figure 10 (modified to include two modems) and depicting the cross-connection of received signals).
