Sandpiper CDN sued Microsoft in the Eastern District of Texas in 2026. The complaint exhibits list multiple patents from the same family, but not U.S. Patent No. 11,218,566. The case is at its initial AO 120 filing stage.
The complaint asserted the '886 patent among a six-patent portfolio including 8,595,778; 8,645,517; 8,719,886; 9,021,112; and 10,924,573. Count IV of the First Amended Complaint alleged infringement of the '886 patent. The court granted Google's motion to dismiss the '886 patent count, holding all 19 claims invalid under 35 U.S.C. § 101.
Google LLC filed an inter partes review petition challenging U.S. Patent 8,645,517, owned by Sandpiper CDN, LLC. The PTAB docket listed the proceeding as filed/pending-instituted, but the exact filing and institution dates were not confirmed.
