Dispute Summary
Samsung seeks to invalidate a CMP‑pad dresser patent (U.S. 9,138,862) by alleging that prior‑art references, especially Sung’026 and related disclosures, anticipate or render obvious all 20 claims. The petition argues public accessibility of the prior art and cites discretionary factors favoring institution.
