Dispute Summary
Simpson Strong‑Tie challenges Columbia Insurance’s post‑grant review of U.S. Patent 11,920,339 covering fire‑wall hanger systems. The patent owner’s sur‑reply argues the petition’s obviousness and written‑description attacks fail, emphasizing strong secondary‑consideration evidence. The case remains pending before the PTAB.
