Patent Office Tightens IPR Rules: What Developers Need to Know

TL;DR

• U.S. Patent Office proposed new rules making it harder to challenge bad patents via inter partes review (IPR)
• Developers and startups lose key defenses if they pursue IPR, blocking future court challenges
• Comment period closes December 2 — file feedback at regulations.gov if this affects your work

What Dropped

The U.S. Patent and Trademark Office has proposed new rules that would severely restrict inter partes review (IPR)—the mechanism Congress created specifically for startups and developers to challenge low-quality patents without expensive federal litigation. The 2025 proposal is significantly worse than a similar 2023 attempt.

The Dev Angle

IPR exists because patent trolls disproportionately target small teams and open source projects. The new rules would impose bright-line restrictions: blocking IPR petitions when a claim has been upheld anywhere, or when parallel litigation is likely to finish first. Worse, petitioners would have to surrender all invalidity defenses in court if they pursue IPR—meaning if you challenge a patent through IPR and lose, you can't challenge it again in court.

This creates a trap. Developers facing a dubious patent would have to choose: risk an expensive federal lawsuit, or use IPR and give up your right to defend yourself later. For open source projects and bootstrapped startups, that's often no choice at all.

The practical impact: patent litigation costs skyrocket for small teams. Trolls know developers can't afford to fight back, so bad patents become enforceable by default. This chills innovation in exactly the communities that drive it—open source, early-stage companies, and independent developers.

Should You Care?

If you maintain open source software, work at a startup, or contribute to projects that could be targeted by patent claims, yes. Patent trolls don't sue Google; they sue the 10-person team that can't afford a defense team.

If you're at a well-funded company with in-house counsel, this is annoying but manageable. If you're bootstrapped or volunteer-driven, these rules could make the difference between fighting a bad patent and capitulating.

GitHub is calling on developers, startups, and open source organizations to file public comments before December 2. The comment period is open at regulations.gov. It takes 10 minutes and directly influences policy.
