Today, Google has introduced a beta version of Patent Search - a search engine for patents. Currently, only US patents are available (about 7 million documents), but a further expansion of the base is planned. Like Google Book Search , the new search engine is equipped with a PDF viewer; when viewing a particular patent, its brief description, list of related materials, etc. are available.
Today also became aware of the new patents Google. The most important thing is that the company “protected” the GUI pages of search results. Now it is theoretically possible that Google will sue those who imitate their “trademark issue”.
