Google took a slap at Microsoft on Tuesday, saying the software giant's patent lawsuit against bookseller Barnes & Noble's Android-based e-reader stifles innovation.
Microsoft sued in U.S. District Court on Monday, alleging that the bookseller's Nook e-readers that run Google's Android mobile OS violate several Microsoft patents.
Google would not say whether it would offer support to the defendant, but it took issue with the case.
"Sweeping software patent claims like Microsoft's threaten innovation," Google said in a statement. "While we are not a party to this lawsuit, we stand behind the Android platform and the partners who have helped us to develop it."
A codefendant in the lawsuit, the electronics manufacturer Foxconn International Holdings, was studying the claim on Tuesday before deciding how to respond. So far it was unfazed.

Fellow codefendant Inventec, also a hardware manufacturer in Taiwan, said on Tuesday it was reviewing the lawsuit and had no immediate comment.
