Squires Denies Apple IPR Under Revvo for Inconsistent Position on Limiting Preambles

USPTO Director John Squires denied Apple's IPR petitions challenging WeCrevention patents, citing inconsistent claim construction positions between PTAB proceedings and Western District of Texas litigation. WeCrevention sued Apple for patent infringement involving LPDDR DRAM in iPhones, MacBooks, and iPads. Apple argued contradictory positions on preamble limitations and means-plus-function claims across venues. Squires applied Revvo precedent, emphasizing petitioners must maintain consistent constructions and avoid strategic gamesmanship between district court and PTAB proceedings.
