Case Overview
The Parties
⚖️ Plaintiff
IP assertion entity focused on monetizing mobile and digital media patents, with a history of licensing campaigns in digital advertising and content distribution.
🛡️ Defendant
A leading subscription video-on-demand platform operating a technically sophisticated streaming ecosystem in the United States.
Patents at Issue
This case centered on two media-routing patents asserted against Hulu, critical to understanding the patentability landscape for streaming technology. Both patents relate to the broader technology category of media delivery architecture.
- • US 10,009,637 — Directed to a system and method for routing media content across networks.
- • US 10,171,846 — Also directed to media routing methodologies, claiming innovations in how media is delivered to end-user devices.

The Verdict & Legal Analysis
Outcome
The Federal Circuit issued a Rule 36 per curiam affirmance on April 5, 2024, upholding the finding that U.S. Patent Nos. 10,009,637 and 10,171,846 are unpatentable. No damages were awarded to SITO Mobile, marking a decisive victory for Hulu. This outcome underscores the Federal Circuit’s stance on software-adjacent patents in the streaming sector.
Key Legal Issues
The verdict cause was categorized as an “Invalidity/Cancellation Action”, strongly suggesting this appeal originated from a USPTO post-grant proceeding, likely an Inter Partes Review (IPR) initiated by Hulu. Invalidity findings typically rest on grounds of obviousness (§ 103), anticipation (§ 102), or lack of patentable subject matter (§ 101). The Federal Circuit’s Rule 36 disposition means the panel found the lower tribunal’s analysis legally sound and factually supported, requiring no further elaboration in a written opinion.

The case involved U.S. Patent Nos. 10,009,637 (App. No. 15/693,811) and 10,171,846 (App. No. 16/017,435), both directed to systems and methods for routing media.
The Federal Circuit issued a Rule 36 per curiam affirmance on April 5, 2024, upholding an invalidity/cancellation finding. Both patents were determined to be unpatentable.
The ruling reinforces that media routing patents are vulnerable to post-grant invalidity challenges, and that major streaming platforms will vigorously defend against NPE assertions rather than settle on unfavorable terms.
