Lawsuit to watch: Nuance sues Vlingo

Nuance, the biggest speech recognition software company in the world, is suing tiny Vlingo, a Cambridge start-up, for patent infringement. Vlingo co-founder Michael Phillips had been a Nuance employee before starting the company, which focuses on speech recognition on mobile phones. He took a year off to sit out his non-compete agreement before starting Vlingo.

From Nuance's press release about the lawsuit:

    In its complaint, Nuance states that Vlingo infringes a Nuance patent that covers a technique for adapting a speech recognition system to the speech of individuals or groups. In the claim, Nuance seeks monetary damages for infringement and injunctive relief to prevent Vlingo from continuing to infringe U.S. Patent No. 6,766,295, entitled “Adaptation of a Speech Recognition System across Multiple Remote Sessions with a Speaker.”


Update: Vlingo's PR rep just sent along this response, from CEO Dave Grannan:

    We believe this lawsuit is unfounded. Nuance has referenced a patent that has serious limitations in its coverage. The patent does not apply to vlingo’s technology; moreover, we have significant doubts regarding the patent’s validity. Vlingo’s technology is based on a license of IBM’s core speech recognition platform, which is used by hundreds of companies worldwide. Industry observers will recognize this as typical counterproductive behavior of filing frivolous lawsuits in an attempt to stifle competition. Vlingo will fight the lawsuit aggressively to its conclusion, while continuing to build on our tremendous momentum we’ve gained in less than one year since our public launch.
