Microsoft is being sued over the technology to "tag" a song through an FM receiver and download it for purchase.
The Seattle-Post Intelligencer reports in its Microsoft Blog that Dr. Edward Yavitz, an Illinois ophthalmologist, says he holds patents for tagging and downloading music and that Microsoft infringed on those patents after he tried to persuade the technology giant to license his idea for the next Zune.
Dr. Edward Yavitz alleges that Microsoft didn't respond to his two letters in 2006 regarding tagging. In his suit, Yavitz asks for a permanent injunction against Microsoft selling the Zune with the allegedly infringing technology, along with treble damages, and court costs.
Microsoft declined to comment on the case for the paper.
Microsoft released the "Buy from FM" Service in 2008, and the Zune HD featuring both RDS and HD Radio tagging in 2009.
