Detailed Summary
Multi-Color Corporation successfully petitioned the PTAB to institute review of claims 1 through 19 of patent 11961422, owned by Brook & Whittle Ltd. The Petitioner raised grounds of anticipation under 102(a)(1), obviousness under 103, and indefiniteness under 112. Crucially, the Board provided a detailed claim construction for 'recyclable shrink label is recyclable with a PET container,' defining it as not requiring removal from the PET stream or containing non-removable contaminants that would contaminate the polymer flake during recycling. Given this clear construction and sufficient evidence across all grounds, the PTAB ruled to institute review on all 19 claims.
