According to the Specification, when compared to the prior art, the alumina flakes of the present invention provide improved optical properties, in particular, increased chroma, higher luster, lower haze and excellent finishing, as well as a high chemical stability.
Patent Owner challenges Petitioner’s declarant, Mr. Ladson, as not being qualified to give meaningful testimony about the perspective of a person of ordinary skill in the art because he does not hold a degree from an accredited university.
Further, Patent Owner notes that Mr. Choi provides no testimony regarding how Merck, or another coatings manufacturer, would typically publish a Technical Data Sheet relative to the product being first made available to the public.
Even if such incentive existed, Petitioner still fails to offer persuasive evidence that the Xirallic lot identified as Sample C was, in fact and not in theory, available to the public prior to either alleged critical date.
Based on the foregoing discussion, we determine that Petitioner’s evidence does not amount to a satisfactory showing that the relied upon Xirallic sample was “in public use, on sale, or otherwise available to the public” prior to either critical date alleged by the parties.
