SCOTUS declines to hear “podcasting patent” case Personal Audio v. Electronic Frontier Foundation, handing win to EFF, after the patent was invalidated in 2015
Back in 2015, Personal Audio's claimed patent was invalidated by a federal court.
Context & Ripple Effects
This cert denial closes a three-stage campaign by EFF against Personal Audio's podcasting patent: the USPTO invalidated key claims after an EFF petition in 2015, an appeals court affirmed the invalidity in 2017, and the Supreme Court has now declined to reopen any of it. The practical effect is finality — the patent that was used to threaten podcasters is dead at every level of the system.
The denial also fits a pattern in the broader docket: SCOTUS recently let stand another win for Apple, Google, and LG in the Gesture Technology Partners dispute over challenging expired patents, suggesting the Court is content to leave patent-patrol work to the USPTO and the lower courts rather than take up trolls' appeals.
First-order effects
- Personal Audio's enforcement campaign is over: with no path to Supreme Court review, its podcasting patent stays invalid and its licensing threats against podcasters have no legal basis.
- EFF wins not just this case but precedent for its petition strategy — using USPTO review to kill asserted patents before litigation damages accrue.
Second-order effects
- Other defendants facing broad software and media patents gain a playbook: challenge validity at the USPTO early, as EFF did here, instead of betting on jury verdicts that judges may later toss for unenforceability, as happened in the $308.5M Apple verdict and the $32.5M Sonos award.
- Non-practicing entities whose business model depends on settlement economics lose leverage when their patents are publicly invalidated — the threat value of a demand letter collapses once the underlying claims are dead.
Third-order effects
- If the pattern holds — repeated cert denials alongside lower-court invalidations and thrown-out verdicts — patent assertion shifts from a courtroom strategy to a narrower one, since both the PTO and the appellate bench are proving willing to unwind broad claims.
- For creators and small platforms like podcasters, the systemic signal is that organized public-interest challenges can function as industry-wide defense, reducing the need for each target to litigate alone.
The trend: Courts and the USPTO are steadily closing off the assertion of broad software and media patents by non-practicing entities, with the Supreme Court declining to intervene on their behalf.
