The Federal Circuit has dismissed an appeal by the Electronic Frontier Foundation (EFF) seeking to unseal summary judgment briefing in a patent dispute involving standard-essential patents for cable modem technology. Entropic Communications, LLC v. Charter Communications, Inc., No. 24-1896 (Fed. Cir. Dec. 17, 2025) (nonprecedential). The CAFed held that the district court did not abuse its discretion in denying EFF’s motion for permissive intervention as untimely under Fifth Circuit law. Because EFF could not establish a right to intervene, the Federal Circuit concluded it lacked jurisdiction to address the substantive question that had drawn significant amicus attention: whether courts may seal judicial records based solely on the parties’ designation of materials as confidential under a stipulated protective order.
In the case, Charter raised a defense based on licensing commitments associated with the Data Over Cable Service Interface Specification (DOCSIS) standard, arguing that Entropic’s patents were standard-essential and therefore encumbered by FRAND licensing obligations. The parties filed extensive summary judgment briefing on this issue, with most materials filed under seal pursuant to a protective order the court had entered. According to EFF, more than 40% of Entropic’s opening summary judgment brief and 76% of Charter’s response were redacted in the public versions. The magistrate judge’s report and recommendation, which was filed publicly without redaction, recommended granting Charter’s license defense. The district court adopted that recommendation, and the parties promptly settled. EFF moved to intervene three months later, seeking to unseal the briefing so the public could understand how courts resolve disputes over standard-essential patent licensing. (more…)
