Case Overview
The Parties
⚖️ Plaintiff
IP-focused entities built around mobile and digital media technologies. SITO Mobile has historically monetized patents related to mobile advertising, content delivery, and media routing—positioning itself as a patent assertion entity (PAE) in the competitive digital media landscape.
🛡️ Defendant
Leading subscription-based streaming service and a major player in the over-the-top (OTT) media industry. Hulu’s robust IP defense posture is well-established, with O’Melveny & Myers LLP consistently representing its interests in complex IP matters.
Patents at Issue
This case involved a media routing patent directly relevant to how digital content is delivered and managed across streaming platforms. The invalidation of this patent carries implications for broader software and media delivery technologies.

The Verdict & Legal Analysis
Outcome
The Federal Circuit **affirmed** the invalidity of U.S. Patent No. 8,825,887 B2 in its entirety. No damages were awarded to the plaintiff. The per curiam designation and Rule 36 affirmance indicate a unanimous, expedited resolution favoring Hulu without the issuance of a precedential written opinion. Specific damages figures were not applicable, as invalidity eliminated the basis for any infringement recovery.
Key Legal Issues
The Federal Circuit’s use of Rule 36—which allows affirmance without a written opinion when the court finds no jurisprudential value in elaborating—is procedurally significant. It signals that the panel found the invalidity ruling below to be clearly correct, leaving no legal ambiguity to resolve on appeal. While the specific legal grounds were not elaborated, invalidity challenges in patent litigation typically proceed on the basis of anticipation (35 U.S.C. § 102), obviousness (35 U.S.C. § 103), or lack of written description/enablement (35 U.S.C. § 112).

The case involved U.S. Patent No. 8,825,887 B2 (Application No. US13/841015), covering a “system and method for routing media.”
The Federal Circuit affirmed the patent’s invalidity under a patentability/invalidity action. The specific grounds from the lower tribunal stand as the operative analysis; the Federal Circuit issued a Rule 36 affirmance without elaborating on separate legal grounds.
It reinforces the viability of invalidity defenses against media routing patents and signals judicial willingness to affirm strong invalidity findings without extensive appellate review—a favorable signal for defendants in the streaming sector.
Companies can protect themselves by conducting freedom-to-operate (FTO) analysis before launching new products or technologies, documenting development thoroughly, considering design-around strategies for high-risk elements, and filing their own patents early in the product development cycle.
