Microsoft late last week was sued for allegedly infringing on patents with the Zune HD's radio app. Illinois-based Edward Yavitz has claimed that the buy-from-radio feature, which lets users tag identified songs on FM or HD Radio and buy them from the Zune Marketplace, copies similar technology that Yavitz patented in 2002. He purportedly contacted Microsoft unsuccessfully about licensing the technology early and billed it as a way of preempting Apple.
