Microsoft, which has already sued Motorola Mobility Holdings Inc (MNM) over its Android phone handsets, said Barnes & Noble's e-readers infringe several Microsoft patents with software used to tab between screens, surf the Web and interact with e-books.

In lawsuits filed in federal court in Seattle and with the International Trade Commission, Microsoft also charged the makers of the devices, Foxconn International Holdings Ltd and Inventec Corp with patent infringement.

"The Android platform infringes a number of Microsoft's patents, and companies manufacturing and shipping Android devices must respect our intellectual property rights," Horacio Gutierrez, deputy general counsel of Microsoft's intellectual property and licensing, said in a statement.

"We have tried for over a year to reach licensing agreements with Barnes & Noble, Foxconn and Inventec. Their refusals to take licenses leave us no choice but to bring legal action to defend our innovations."

Barnes and Noble said its policy is not to comment on litigation. Foxconn and Inventec could not immediately be reached for comment.
