Quinn Emanuel Urquhart & Sullivan and a startup founded by researchers at the Massachusetts Institute of Technology have won a skirmish in a trade secret dispute with Facebook over artificial intelligence algorithms.

U.S. District Judge Denise Casper of the District of Massachusetts ruled last week that Massachusetts' version of the Uniform Trade Secrets Act does not preempt Somerville-based Neural Magic's additional claims for unfair competition, unjust enrichment and tortious interference.

The ruling in Neural Magic v. Facebook means that Neural Magic can still pursue unfair competition claims—and treble damages—under Massachusetts Chapter 93A, even if it's ultimately unable to prove that confidential information its chief technology officer allegedly took to Facebook does not meet the definition of a trade secret.
