The lawsuit by Rosetta Stone was the ninth keyword trademark suit brought against Google.

It seems that suing Google has become new pastime for Google's critics and competitors. There has been lot heard about Anti-trust cases against Google across the globe which include strict observation by the U.S. Government, Chinese Govt.'s red eyes on Google over porn search results and many other such cases.The most recent is one from Rosetta Stone. Rosetta Stone is a language-learning firm which has recently filed a lawsuit in the U.S. federal court against Google, claiming that the company is infringing on its trademarks.Rosetta Stone has put allegations that Google allows third parties including individuals involved in software piracy to purchase the right to use Rosetta Stone trademarks or other terms confusingly similar in Google's Adwords advertising program. In June 2009, Google changed its policy stating that "advertisers will be allowed to use trademark terms in their ad text even if they do not own that trademark or have explicit approval from the trademark owner to use it.""Google's search engine is helping third parties mislead consumers and misappropriate Rosetta Stone trademarks by using them astriggers for paid advertisements and by using them within the text or title of paid advertisements," said Michael Wu, general counsel, Rosetta Stone.
