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.

“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).

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.

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.

“to determine a characteristic [of the chick] . . .

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.

“Here, the teachings of Linhult, Abrahmsén, and Hober suggest mutating the glycine at position 29 for an alanine in any one of the IgG binding domains of E, D, A, B, or C of SPA in order to avoid protein degradation. Ex. 1004, 2; Ex. 1005, 5:4–9. We, therefore, agree with Petitioner that the art expressly suggests that the glycine codon can be mutated for an alanine codon in any one of the SPA IgG binding domains E, D, A, B, or C. Pet. 23 (citing Ex. 1002 ¶¶ 99–111). Attaching any one of SPA mutated IgG binding domains E D A B or C to a matrix using “known ligand-construction methods to yield a predictable result[] (e.g., the claimed affinity chromatography matrix)” would have been obvious. Pet. 25 (citing Ex. 1002 ¶ 130).

“We also adopt the parties’ position that the preamble of claims 1 and 7 is not limiting beyond the term “granule.” Claims 1 and 7 each recite “[a] chemically stable dry flow, low compact, dust free soluble phosphoramidothioate granule consisting of” the set of ingredients recited in body of those claims. Ex. 1001, 7:44–45, 8:19–20. While the wherein clause describing the dimensions of “said granule” relies on “granule” in the preamble for antecedent basis, none of the other preamble language appears to be necessary to breathe life and meaning into the claim, and the claim body recites a structurally complete invention. See Catalina Marketing Int’l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed.

“We find that Dr. Dayan’s testimony on these points lacks sufficient supporting analysis. In opining that the tested substituents are representative of the steric and electrostatic properties across the claimed substituents, Dr. Dayan merely compares the properties of the tested substituents to each other. See, e.g., id. ¶¶ 52–56. He does not expressly compare them to the properties of the many remaining, untested substituents within the scope of the claims. See id.; see also Reply 14 (“At best, [Dr.] Dayan testified that the positive activity . . . at each substituent” suggests that the position is involved in herbicidal activity, “not that the tested compounds were sufficient to provide any reasonable expectation of success as to the billions of structurally diverse compounds covered” by the claims.). And although Dr. Dayan acknowledges that several tested compounds showed no herbicidal activity, he does not expressly explain how he took these compounds into account in nevertheless concluding that an ordinarily skilled artisan would expect at least some activity across all claimed substituents. See, e.g., Ex. 2011 ¶¶ 54–56 (noting exceptions to herbicidal activity). As one example, Dr. Dayan acknowledges the lack of activity shown in the data for substituents larger than hydrogen at the R6 position, but does not explain the impact of that data on the remaining claimed substituents. See id. ¶ 54 (Dr. Dayan noting that activity is “not as favored by larger alkyl groups” at R6, but nevertheless concluding that “one would expect at least some herbicidal activity” across all claimed R6 substituents). In contrast, Dr. Hunt compares the size and properties of the R6 substituents that showed no activity with the size and properties of other claimed but untested R6 substituents. Ex. 1003 ¶¶ 163, 166–68; Ex. 1029 ¶¶ 37, 38. This comparison indicates that the majority of R6 substituents are larger than the tested substituents, such that the vast majority of the claimed compounds (i.e., those with compounds having R6 substituents larger than those tested), could have no herbicidal activity. Ex. 1003 ¶ 167; Ex. 1029 ¶¶ 12, 37, 38. Thus, we find that the data in the Specification regarding at least position R6 gives a person of ordinary skill in the art reason to doubt that substantially all compounds within the full scope of claim 1 of the ’202 patent would exhibit herbicidal activity. Ex. 1003 ¶ 163; Ex. 1029 ¶¶ 11, 12, 38; In re Surrey, 370 F.2d 349, 355 (CCPA 1966) (“[W]here the applicant seeks to obtain a monopoly in exchange for his disclosure of a group of compounds there should be a disclosure which gives a reasonable assurance that all, or substantially all of them are useful.”).” slip op. at 29

“We find that the need for iterative QSAR modeling, together with the sheer number of candidate compositions that must be synthesized (each of which would take at least a week to make) for both the modeling and herbicide testing, weighs against enablement, especially in light of the limited guidance in the Specification and the general unpredictability in the art. 3. Conclusion In sum, it is undisputed that claim 1 covers at least a billion compounds. The art is unpredictable, and the Specification indicates that not all of the compounds falling within claim 1 are effective herbicides. See, e.g., Pet. 22 (listing compounds that showed no herbicidal activity). Although the level of ordinary skill in the art is relatively high and the field is mature, Petitioner establishes by a preponderance of the evidence that the ’202 patent does not provide sufficient meaningful guidance or working examples across the full scope of claim 1 to allow a person of ordinary skill in the art to determine which other compounds across the full scope of the claim have herbicidal activity without undue experimentation.” slip op. at 45
