Short Summary
The PTAB upheld the patentability of claims 1-9 for Molecular Loop Biosciences against Illumina. The Board rejected all grounds of anticipation and obviousness over prior art like Chee, finding that the required 'collapsing step' necessitates combining both target sequence and differentiator tag information.
Detailed Summary
In this Final Written Decision, the PTAB denied the petitioner’s arguments that claims 1-9 were unpatentable under 35 U.S.C. §§ 102 or 103. The Board clarified key terms, establishing that 'collapsing step' is distinct from the 'determining step,' and ultimately found that prior art (including Chee) failed to teach the essential combination of target sequence and differentiator tag required for accurate error correction as claimed. The patent owner successfully demonstrated conception and diligence regarding the invention.
