      “We are persuaded by Patent Owner’s argument that claim 1 is not obvious over Avellan because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 21–23. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. PO Sur-reply 20. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

      “For purposes of this Decision, we adopt Petitioner’s definition of a POSITA. Petitioner’s witness (Mr. Cook) qualifies as a POSITA under this definition, and, therefore, is qualified to opine from the perspective of a POSITA on technical matters included within the areas of expertise prescribed by the definition. As indicated above, Petitioner’s definition of a POSITA does not require education in the field of optics and professional experience designing or analyzing optical apparatus, unlike Patent Owner’s definition. We are aware, however, that Patent Owner’s witness (Dr. Klopp) has more extensive experience with optical systems and methods than Petitioner’s witness (Mr. Cook). Compare Ex 1003 ¶¶ 8–14, Ex. 2005, 39:21–59:17, with Ex. 2003 ¶¶ 3–20, Ex. 2004, 1–2, Ex. 1015, 10:22–13:25. Although Mr. Cook possesses excellent credentials in the field of mechanical engineering, his experience in the design and analysis of optical systems and methods is sparse and insubstantial compared to that of Dr. Klopp. Id. Due to this difference in experience levels, in instances where the witnesses express differing views on factual issues related to optical systems and methods, we will accord more weight to Dr. Klopp’s testimony than to Mr. Cook’s.” slip op. at 8

      “through the light transmission portion and bottom output face 313 of light conductor 38, which teaches transmitting light in parallel with the longitudinal axis of the housing. Tseng does not disclose or teach that light is emitted through the side surface of annular protrusion 383 in a direction perpendicular to the longitudinal axis of the housing. Ex. 1004 ¶ 97. Petitioner’s assertions that this would be the case consist solely of conclusory statements, supported only by citations to Mr. Cook’s declaration. Mr. Cook, however, simply repeats Petitioner’s conclusory statements, without providing sound technical reasoning supported by objective evidence to explain and support his opinions. Ex. 2003 ¶¶ 101– 102, 105, 195–198, 202. We, therefore, accord little weight to Mr. Cook’s opinion on this particular matter because it “merely repeats, verbatim, the conclusory assertion for which it is offered to support,” and “does not cite to any additional supporting evidence or provide any technical reasoning [in] support.” Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). Furthermore, Mr. Cook’s opinion conflicts with that of Patent Owner’s witness, Dr. Klopp, who opines that a “POSITA would understand from Tseng’s third embodiment that light from the LED would bypass the annular protrusion 383 of outer cliff 381, while transmitting downwardly toward the output face 313.” Compare Ex. 1003 ¶¶ 174–175, 190–194, with Ex. 2003 ¶¶ 101–102, 105. As discussed above, Mr. Cook is qualified to opine from the perspective of a POSITA on technical matters included within the expertise of a person meeting Petitioner’s definition of a POSITA, which do not include optics and optical apparatus. We, therefore, credit Dr. Klopp’s opinion over that of Mr. Cook on this particular factual issue of how it is directly related to optical systems and methods about which Mr. Cook possesses limited relevant experience. See Ex. 1003 ¶¶ 6–15 (experience in communication systems and electronics); Ex. 2005, 55:16–58:19 (design experience with electronics that use indicator lights or fiber-optic communications; no professional experience with light pipes, diffusers, or plumbing fixtures). Dr. Klopp possesses substantial research and professional experience with optical methods, fiber optic light pipes, light guides, diffusers, prisms, and analysis of faucets, spray heads, and plumbing fixtures. See Ex. 2003 ¶¶ 6–10 Supra 8 (discussing weight accorded to conflicting witness testimony); see also Resp. 2–3 (arguing that “Petitioner’s expert, Mr. Cook, is a mechanical engineer with substantial professional experience in electronics for high-voltage power systems and communications, but he has limited experience with the claimed subject matter.”).” slip op. at 34

      “In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (citing Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986)). “These factors are not exhaustive but are 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). There is uncontested evidence in the record before us, including the ’124 patent, the Gershman, Pierre, Yavnai, Tao, and Goodwin references, and the background and qualifications of both sides expert witnesses that reflect the knowledge and experience of a POSITA, including knowledge of systems for assessing and transporting poultry in an industrial setting. Patent Owner’s proposed skill level overlaps with Petitioner’s proposed skill level, and any differences would not alter the outcome of this proceeding. Therefore, we adopt Patent Owner’s proposed skill level with two modifications. A POSITA also could have a Bachelor of Science degree in Animal Science or similar discipline, and a POSITA would be familiar with techniques for assessing and transporting poultry in an industrial setting, such as visual and/or anatomical characteristics of a chick.” slip op. at 7

      “Therefore, we find that Applicant distinguished Tao from “an unrestrained chick” because in Tao’s automated system a chick is restrained—the chick is held in place—by a retainer unit on a moving platform, whereas in Applicant’s claimed system a chick is not held in place on a moving platform. We further conclude that Applicant’s reason for distinguishing the claimed invention over Tao informs the claim construction even if the “prosecution history statements do not rise to the level of unmistakable disavowal . . . .” Personalized Media, 952 F.3d at 1345 (Fed.

      “to determine a characteristic [of the chick] . . . [that] manifests in one of two or more possible states, e.g., sex (male vs. female), health (healthy vs. unhealthy), genetic mutation (present vs. not present).” Reply 13 (citing Ex. 1004, 3). The recitation of a generic “database of images” does not distinguish limitation [1.4] from the asserted combination of Gershman-Pierre, particularly in view of Pierre’s disclosure of “a computerized processing process is implemented in order to compare the captured images to reference images,” as asserted in the Petition. Ex. 1004, 3 (emphasis added); see Pet. 23–24 (citing Ex. 1003, 2–5; Ex. 1004, 3, 5). Thus, we find that storage of Pierre’s reference images of male and female wing feathers in a database used for comparison in Gershman’s computerized digital chick image processing system would have been obvious to a POSITA and satisfies limitation [1.4].19 We agree with Petitioner that it would have been obvious and well within the skill level of a POSITA—someone with a Bachelor of Science degree in agricultural, industrial, or electrical engineering and two years of experience in industrial poultry sexing and/or image processing (Resp. 20)—to store reference images as taught by Pierre in a “computerized processing” database. The rationale argued by Petitioner, to organize the collection of reference images for comparison to determine whether the characteristic of interest was present, finds direct support in Gershman and Pierre. Both references disclose comparing digital images of a chick’s wing feathers to reference data (Gershman) or reference images (Pierre) of male and female chick wing patterns. Pet. 23–24; Reply 12–13.

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.

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.

      “We agree with Patent Owner that a showing of motivation is required. Whether a proposed combination rests on “combining disclosures from multiple references, combining multiple embodiments from a single reference, or selecting from large lists of elements in a single reference, there must be a motivation to make the combination and a reasonable expectation that such a combination would be successful.” In re Stepan Co., 868 F.3d 1342, 1346 n.1 (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. Therefore, we do not agree with Petitioner that no motivation to combine the Figure 3 and Figure 83 embodiments of Fukumoto need be shown.” slip op. at 29

      “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. Patent Owner also asserts that “[a]dditional relevant industry experience may compensate for lack of formal education or vice versa.” Id. Dr. Goossen’s testimony supports Patent Owner’s assertions.

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. See Pet. 9–35; Reply 16–22. Patent Owner disputes Petitioner’s contentions. See Resp. 18–27; Sur-reply 7–14. Below, we provide an overview of Fukumoto. Then, we consider the obviousness issues. 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. Braun Med., Inc., v. Abbott Lab’ys, 124 F.3d 1419, 1424 (Fed. Cir. 1997). When a limitation recites two or more functions, the specification” slip op. at 18

      “prosecution history and the amendment changing “held at” to “accessible at,” testimony upon which Patent Owner relies to support its position. Specifically, Dr. Medvidović testifies that a person having ordinary skill in the art would have understood the two phrases to be synonymous because, 1) the amendment was not made to overcome a prior art reference, 2) the applicant did not make a statement disclaiming that “being accessible at” does not encompass “being held at,” and 3) the examiner did not object to the amendment as exceeding the scope of the Specification. See Ex. 2005 ¶ 34. We find that Dr. Medvidović’s conclusion is not supported by his reasoning. First, an amendment made not to overcome a prior art reference does not mean an amendment that does not change the scope of a claim. An applicant is free to amend a claim at any time during prosecution, even an amendment that may expand the scope of a claim (one made not to overcome a prior art rejection). Second, whether “being accessible at” encompasses “being held at” is not the issue—because the scope of one term encompasses the scope of another term does not make the two terms” slip op. at 26

      “Petitioner asserts that “it was known that implementing a variable transmission in a milling machine could improve fuel efficiency” (id. at 33–34), and relying on the declaration testimony of Dr. Stein, reasons that one of ordinary skill in the art “would have recognized that using a hydromechanical CVT permitted controlling an engine to a speed that minimizes fuel consumption for a given load while controlling transmission gear ratios to achieve desired transmission output speeds that maximize machine performance.” Id. at 34 (citing Ex. 1003 ¶ 66). Petitioner further asserts that Xing taught a method of controllably adjusting a CVT to further improve fuel efficiency without impacting machine performance. Supra [Pet. 18–24]. Thus, implementing a CVT and control method like that taught by Xing in Willis’s milling machine would have been a matter of combining prior art elements according to known methods to yield predictable results. Id. (citing Ex. 1003 ¶ 66). Relying on the declaration testimony of Dr. Stein, Petitioner takes the position that one of ordinary skill in the art “would have expected to successfully incorporate Xing’s teachings, including those related to CVTs, engines, transmission control algorithms, and associated sensors, into Willis’s milling machine” because it would have been no more that the combination of “prior art elements according to known methods to yield predictable results.” Pet. 34 (citing Ex. 1003 ¶¶ 65–66); see also id. at 34–35 (“This combination would further apply a known technique and hardware to a known device that was ready for improvement, predictably yielding the result of the expected improvement.”).

      “Owner’s counterarguments and find, on the complete trial record, that Petitioner demonstrates, by a preponderance of the evidence, that the combination of Willis and Xing teaches or suggests “determining an engine load of the engine” and “adjusting an engine speed of the engine based on the engine load” as recited by limitation 1[b], and recited in part by limitation 1[c]. Petitioner explains that Xing’s controller 116 “receive[s] signals from sensors communicatively coupled to the controller, such as torque sensor 122 and engine speed sensor 124” (Pet. 45 (citing Ex. 1006, 8:16–40)), and [b]ased on those signals, the controller in Xing evaluated power losses from the transmission and other power consuming components at different candidate operating speeds, measured engine load to determine the work output demanded of the machine, and independently set engine speeds and transmission ratios to minimize fuel consumption while achieving desired performance. Id. at 46 (citing Ex. 1006, 8:67–9:3, 9:9–17). We find Petitioner’s explanation to be consistent with Xing’s disclosure that the current load power requirement for the work vehicle may be determined indirectly by calculating the current engine power (Pengine) and the current power loss (Ploss) for the work vehicle 10. For example, as indicated above, the controller 116 may be configured to continuously monitor the engine speed and the engine torque (via sensors 122, 124), thereby allowing for the current engine power to be calculated by the controller 116. Ex. 1006, 9:37–44; see also id at 9:27–31 (“The relationship between the load power requirement and the power produced by the engine 22 of the work vehicle 10 is provided” by Equation 1: “Pengine = Pload + Ploss.”).” slip op. at 34
