Microsoft is suing Barnes & Noble and two electronics manufacturers, saying the Nook e-book reader infringes on patents.

Microsoft Corp. said Monday that it filed a federal lawsuit in U.S. District Court in Seattle. The software maker also lodged a complaint with the International Trade Commission.

Microsoft says the Nook, which uses Google Inc.'s Android software, steps on patented technology for opening a separate window to help make navigating content easier. The company also says it has patents for easily selecting and annotating text and for loading Web pages quickly.

In addition to Barnes & Nobile Inc., Microsoft is suing manufacturers Inventec Corp. and Foxconn International Holdings Ltd., part of Hon Hai Precision Industry Co., both based in Taiwan.
