Microsoft faces lawsuit over Silverlight

The company has been sued for patent infringement by a little known video metadata company called Gotuit Media.

Microsoft's latest legal headache is a suit from a little-known company called Gotuit Media, which charges elements of Silverlight infringe on the video metadata company's patented technology.

In a suit filed July 2 in San Francisco Federal Court, Gotuit charges Silverlight infringes on several of its patents and seeks an injunction against the software maker as well as damages and attorney's fees.

Gotuit may be a relative unknown, but Microsoft is facing an opponent it knows quite well. Gotuit is represented by San Francisco-based lawyer Spencer Hosie, the same Hosie that successfully represented Burst.com in its suit against Microsoft.

Hosie declined to comment on the Gotuit case.

Of note, Gotuit, in its complaint, mentions specifically Microsoft's plans to use Silverlight in conjunction with video metadata as part of its powering of the NBCOlympics.com Web site . Silverlight is Microsoft's rival to Adobe's Flash for Web video , among other uses.

Microsoft spokesman David Bowermaster said the company had yet to be served in the case, "so we're not in a position to comment."

Gotuit has a range of products used by customers like Lifetime television to make it easier to search and navigate through online video.
