Archrivals microsoft and Google have teamed up to sue a company called GeoTag, claiming the company improperly used a patent to file lawsuits against several hundred organizations. The complaint, which lists only Microsoft and Google as plaintiffs, was filed in U.S. District Court in Delaware and seeks to invalidate a patent granted in 1999 that GeoTag has used to sue at least 397 entities in the last year. Microsoft and Google are not among the companies sued by GeoTag, but big names such as Match.com, Gap and Home Depot have been targeted. According to NoSoft-warePatents campaign founder Florian Mueller, "Microsoft and Google want to protect Google Maps and Bing Maps against this kind of activity."
