Short Summary
Microsoft seeks Director Review of a PTAB institution decision that ordered review of an expired content‑delivery patent owned by Sandpiper CDN. The petition argues the Board misapplied settled‑expectations doctrine and misread the district‑court record, making the decision an outlier.
Detailed Summary
In a Request for Director Review, Microsoft challenges the PTAB’s decision to institute inter partes review of Sandpiper CDN’s U.S. Patent No. 8,478,903, which covers alias‑name mapping in content delivery networks. The petitioner argues that the Board improperly applied the settled‑expectations doctrine to an expired patent, mischaracterized a brief district‑court procedural pause as a stay, and relied on a single prior‑art reference (Kenner) that does not disclose critical claim limitations. Citing numerous prior decisions where expired patents were denied review, Microsoft contends the institution decision is inconsistent and arbitrary, and urges the Director to reverse it.
