OpenAI, Microsoft win partial dismissal in developer AI training suit
Is this a scandal?
Not yet — an early signal. Noise 47/100, holding steady, across 1 source.
Plaintiffs will likely amend complaints to address deficiencies identified in the ruling because courts typically grant leave to replead dismissed claims when curable defects exist.
Noise 47/100 — louder than 99% of tracked AI controversies.
Why it matters
This ruling narrows viable legal theories for software copyright cases against AI firms, potentially setting precedent for how code ingestion is adjudicated.
Key points
- Federal judge dismissed multiple claims against OpenAI and Microsoft in software developer lawsuit on September 16, 2026
- Core copyright infringement allegations regarding AI training data ingestion survive the motion to dismiss
- Defendants successfully argued certain counts were legally insufficient or preempted by federal copyright statutes
- Ruling establishes stricter pleading standards for future AI training data litigation involving software code
- Case proceeds to discovery phase on remaining substantive intellectual property claims
The story
A federal court has partially dismissed a software developer lawsuit against OpenAI and Microsoft regarding alleged unauthorized use of code for AI training. The judge ruled on September 16, 2026, that specific claims failed to state valid causes of action, though core copyright infringement allegations remain pending. Plaintiffs had accused the companies of improperly ingesting proprietary software repositories to train GitHub Copilot and other models without licensing agreements. Defendants successfully argued that certain counts were legally insufficient or preempted by federal copyright law. This decision represents an early procedural victory for AI developers facing similar litigation but does not resolve the underlying dispute over fair use. Legal experts note the ruling clarifies pleading standards for future AI training lawsuits while leaving substantive intellectual property questions for later proceedings. Both companies continue to face active discovery in the remaining claims.
Who's involved
Alleges defendants unlawfully profited from unlicensed ingestion of proprietary source code
Denies copyright infringement and argues AI training constitutes fair use of publicly available code
Contends GitHub Copilot development complied with applicable licenses and copyright law
