“Summary Based upon the record as presently developed, we conclude that Petitioner has met its burden of showing a reasonable likelihood of showing at trial that at least claim 1 of the ’370 patent is obvious over the cited prior art.

Cir. 2001) (the prior art itself may reflect an appropriate level of skill in the art). However, at this point we reject the portion of Petitioner’s proposed definition that includes having “access to other individuals with that knowledge and experience,” as not reflecting the individual level of skill of a given skilled artisan.

Consequently, and for the purposes of this Decision, we adopt Petitioner’s proposed definition as defining a person of ordinary skill in the art as a person who would have had “a Ph.D. in immunology, molecular biology, cellular biology, or a similar field, or an M.D. with similar experience, and would further have had at least five years of experience with antibodies and antibody engineering.”” slip op. at 6

“We find, based upon the present record and for the purposes of this Decision, that Petitioner has sufficiently established that a person of ordinary skill in the art would have been motivated to combine the teachings of Wei and Liu to determine the activity and suitability of Liu’s humanized anti- EGFR antibodies in an ADC. We acknowledge that Liu is silent regarding the pH selectivity or tissue preference of its binding affinity, but Patent Owner points to no prior art reference that would have informed a skilled artisan upon this point or that would have discouraged a person of ordinary skill in the art from combining the references. See fn.7, supra. And, even if a skilled artisan might have recognized that Liu’s humanized cetuximab might have been potentially problematic if it failed to show pH-selective activity like Wei’s Y104D, the mere fact that some disadvantage may come with an advantage when combining prior art does not foreclose their combination under § 103. Medichem, S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). In the instance of Liu’s humanized anti-EGFR antibody, a person of ordinary skill in the art would have recognized that its advantages (enhanced activity against tumor cells compared to chimeric cetuximab, thus requiring smaller dosages) could balance or outweigh its possible disadvantages (e.g., possible activity against non-tumor cells). Furthermore, it is in the nature of scientific research to continue to try new substitutions in drug therapy, even if a promising candidate has been discovered. As the Supreme Court stated in KSR: When there is a design need or market pressure to solve a problem and there are a finite number of identified, predictable solutions, a person of ordinary skill has good reason to pursue the known options within his or her technical grasp. If this leads to the anticipated success, it is likely the product not of innovation but of ordinary skill and common sense. In that instance the fact that a combination was obvious to try might show that it was obvious under § 103. 550 U.S. at 421.” slip op. at 39

“To determine how a person skill in the art would determine if a shrink label is “recyclable” as recited in the independent claims, we look to how the Specification of the ’422 Patent describes or defines recyclable shrink labels. For example, the ’422 Patent states that PET shrink films are generally considered recyclable if no inks are retained on the film after a caustic wash cycle typically used in PET reclaiming processes. Ex. 1001, 6:61–65. The ’422 Patent further states that labels are fully recyclable if the polymers used are clear, preferably clear PET, and the labels include inks that can be washed off in a “typical PET recycling wash (caustic wash).” Id. at 11:44– 49; see also id. at 11:49–54 (describing embodiments in which the labels are free or substantially free of inks that cannot be washed off in a caustic wash or where the labels are free or substantially free of color plastics that cannot be recycled). The ’422 Patent further discusses “industry standards” for determining whether various embodiments of shrink labels are recyclable. See, e.g., id. at 11:29–53. For example, the Specification states that the “Association for Plastic Recyclers (APR) Critical Guidance Protocol for Clear PET Articles with Labels and Closures (PET-CG-02)” (Ex. 1005) can certify that a film is fully recyclable with a container or bottle. Id. at 11:34– 38. Additionally, the Specification states that labels “are recyclable according to the Evaluation of the Near Infrared (NIR) Sorting Potential of a Whole Plastic Article (SORT-B-01)” (Ex. 1010) and/or the “Evaluation of Sorting Potential for Plastic Articles Utilizing Metal, Metalized, or Metallic Printed Components (SORT-B-03)” (Ex. 1011). Ex. 1001, 11:39–44. The ’422 Patent further states that embodiments of the labels “are fully recyclable. For example, the labels may include inks that can be washed off in a typical PET recycling wash (caustic wash) and the polymers” are preferably clear PET. Id. at 11:44–48. The ’422 Patent thus provides various descriptions or standards to determine the recyclability of shrink labels. For the purposes of addressing the anticipation and obviousness grounds, we determine that any of these standards can be used to determine if a shrink label is “recyclable.” We note that our construction is preliminary and is based on the present record. We invite the parties to further the address the construction of “wherein the recyclable shrink label is recyclable with a PET container” during trial.” slip op. at 12

“As an initial matter, we note that, of the 44 specimens tested by Ye, as revealed in Ye’s Table II, only a single specimen, specimen 15, meets the required TC ratios recited in challenged claim 1 of the ’541 patent. Furthermore, none of the references cited by Petitioner teach, or even remotely suggest, the four requisite TC ratios recited by challenged claim 1. We find Petitioner’s argument that a person of ordinary skill in the art would have been motivated to exclusively select Ye’s sample 15, out of the remaining 43, to which to apply the teachings of Hara and Otsuka concerning the requisite tensile strength and weight deviation ranges in the hope of arriving at the claimed invention, is implausible. Indeed, only the ’541 patent, among all of the evidence of record, that actually mentions the required texture coefficient ratios recited in challenged claim 1. Petitioner provides no convincing argument as to why a skilled artisan would have selected sample 15 for combination with Hara and Otsuka. Rather, Petitioner’s argument appears to be based upon impermissible hindsight reconstruction. However: Any judgment on obviousness is in a sense necessarily a reconstruction based upon hindsight reasoning, but so long as it takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant's disclosure, such a reconstruction is proper. In re McLaughlin, 443 F.2d 1392, 1395 (C.C.P.A. 1971). Accordingly, Petitioner’s failure to suggest a reason as to why a person of ordinary skill in the art would have been motivated to select that single specimen, without knowledge of the specific TC ratios disclosed by the ’541 patent argues against Petitioner’s contention that the claims are obvious.” slip op. at 47

The teachings in the prior art support the presently unrebutted testimony of Dr. Randall explaining why the POSA would have been motivated to modify Kim ’761’s copper foil to have the claimed TC(220) and ΔRz/Ra.

If so, then the optimization of that parameter is ‘normally obvious.’”).
