“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. Storing digital reference images in a database for comparison to captured digital images is, moreover, a basic and straightforward task in any computerized image processing” slip op. at 44

Cir. 2024) (“Where [a gap in prior art] includes a parameter not necessarily disclosed in the prior art, it is not improper to consider whether or not it would have been recognized as result-effective. If so, then the optimization of that parameter is ‘normally obvious.’”). Accordingly, we are not persuaded by Patent Owner’s argument that Petitioner failed to articulate a sufficient motivation to combine the references. To the contrary, the preliminary record presents a strong showing that the POSA would have been motivated to combine the references in the manner described in the Petition.” slip op. at 38

“At this stage of the proceeding, Patent Owner does not contest Petitioner’s definition of the level of skill in the art. Prelim. Resp. 4 (“For purposes of this Preliminary Response, Patent Owner applies Petitioner’s level of skill for a person of ordinary skill in the art”). Petitioner’s definition appears to be consistent with the field of the invention reflected in the prior art of record and the disclosure of the ’706 patent. Accordingly, for purposes of this Decision, we adopt Petitioner’s proposed definition of the person of ordinary skill in the art.” slip op. at 21

“experience working on the development of materials or components for electronic devices such as batteries.” Pet. 2. Petitioner further contends that “[a]dditional education, such as a graduate degree, could compensate for less work experience, and additional work experience could compensate for less formal education.” Id. Patent Owner states that, “[f]or purposes of this Preliminary Response, Patent Owner applies Petitioner’s level of skill for a person of ordinary skill in the art.” Prelim. Resp. 4. For purposes of this Decision, we adopt Petitioner’s undisputed proposed definition because it appears to be consistent with the cited prior art and the disclosure of the ’014 patent. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus.

Under this standard, claim terms are generally given their plain and ordinary meaning as would have been understood by a person of ordinary skill in the art at the time of the invention and in the context of the entire patent disclosure.

Patent Owner contends that “[t]he Board need not construe any term in order to determine that institution should be denied.” Prelim. Resp. 4. Based on the record before us, we determine that no claim term requires express construction for purposes of this Decision. See Realtime Data, 912 F.3d at 1375.” slip op. at 8

“For these reasons, we are not persuaded that Petitioner sufficiently establishes that a POSITA would have been motivated to modify Hanafusa in light of Dobashi with a reasonable expectation of success as Petitioner contends. Accordingly, we determine that Petitioner fails to demonstrate a reasonable likelihood of prevailing in its assertion that the subject matter of claim 1, and claims 4 and 8 that depend therefrom, would have been obvious over the combined teachings of Hanafusa and Dobashi.” slip op. at 18

“Petitioner also focuses on Hanafusa’s teaching that all known methods can be used to make a rough surface low-profile, and Dobashi’s teaching that RSm can be used as an indicator for judgment of the surface, to support its contention that a POSITA would have been motivated to apply Dobashi’s RSm to further achieve Hanafusa’s purpose, without explaining how and why that would be the case. In particular, neither Petitioner nor Dr. Josefowicz adequately explain why a POSITA looking for ways to make Hanafusa’s surface roughness low-profile would look to methods to achieve as the period of waviness, RSm can also be used as an indicator for judgment of the surface.” Ex. 1005, 2:66–3:1, 6:23–26. Dobashi explains that waviness is “an indicator for determining whether the fine pattern forming performance is good or bad,” and “[t]he surface has small waviness and is smooth when RSm is large, and the surface has large waviness and is rough when RSm is small.” Id. at 3:1–3, 6:27–29. Dobashi also teaches that surface roughness Rzjis is used as a low-profile indicator. Ex. 1005, 2:66– 3:1. Dobashi, therefore, teaches that RSm is an indicator of surface waviness, which Dobashi explains is different than surface roughness. Id. at 2:66–3:3, 6:23–29. Given these teachings in Dobashi, neither Petitioner nor Dr. Josefowicz sufficiently explains how or why a POSITA would have been motivated to implement Dobashi’s RSm values to make Hanafusa’s surface roughness low-profile.
