Short Summary
Meta Platforms has filed an IPR petition seeking to invalidate Sterling Computers' 7,716,217 patent covering email relevance scoring, citing obviousness over Dumais, Rose, and a Rose‑Bieganski combination.
Detailed Summary
In Petition IPR2025-00430, Meta Platforms, Inc. challenges claims 1‑3, 5‑9, 13‑15, 18‑19, and 22 of U.S. Patent No. 7,716,217, which describe a system for determining relevance scores of electronic content such as email. The petitioner argues that each challenged claim is obvious in view of three prior‑art references: Dumais (U.S. Pat. App. Pub. No. 2007/0016553 A1), Rose (U.S. Pat. No. 6,202,058 B1), and a combination of Rose with Bieganski (U.S. Pat. No. 6,334,127). The petition also contends that discretionary denial under §314(a) and §325(d) would be inappropriate, emphasizing the lack of a substantial relationship with other challengers and the petitioner’s first challenge of the ’217 patent. An expert declaration by Dr. Edward A. Fox supports the obviousness arguments. No claim construction is asserted, and the petition seeks institution of the IPR.
