An Illinois man continues Microsoft, the Seattle Post-Intelligencer reports, saying the company has added its patented technology for Zune by not responding to his offer of licenses in March 25, 2010. Edward Yavitz, MD, said that Microsoft had infringed two patents covering a method of marking and downloading music via an FM receiver.
 
Yavitz said he wrote to Microsoft in 2006, offering to throw ideas patented in 2000 and 2002, and the company responded to his letter. In 2008, Microsoft introduced the “Buy from FM” feature on the Zune.

Yavitz’s complaint says, “Despite using Dr. Yavitz’s patented proposal and adopting it as a centerpiece of its Zune strategy, Microsoft has never responded to Mr. Yavitz and never tried to obtain a license for patents. ”

Microsoft declined the paper’s request for comment on the suit.
