Microsoft has filed a patent infringement lawsuit against Barnes & Nobel and its partners, Foxconn International Holdings Ltd and Inventec Corporation, alleging that their Android based Nook e-reader violates its patents.
The lawsuit, which has been filed with both the US International Trade Commission and the US District Court for the Western District of Washington, names Nook e-reader and the Nook Color tablet as infringing products.
The company said in a blog post that it was currently defending 25 of its patents against infringement by smartphones, tablets and other devices running on Android OS.
Microsoft said that unlike HTC, Barnes & Nobel, Foxconn and Inventec were unwilling to license its technologies for developing devices based on Google's Android operating system.
Horacio Gutierrez, Corporate Vice President and Deputy General Counsel for Intellectual Property & Licensing, said in a statement, “HTC, a market leader in Android smartphones, has taken a license under this program. 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 and fulfill our responsibility to our customers, partners, and shareholders to safeguard the billions of dollars we invest each year to bring great software products and services to market,” he added.
