Finding patent information: Google Patents
What is Google Patents
Google Patents is Google’s own patent search tool. It draws on patents from more than 100 of the biggest patent offices from around the world, enabling you to search across more than 120 million documents. As such it rivals the EPO’s Espacenet for coverage. Full-text patent documents are indexed from 20 of the biggest patent offices. There is an advanced and basic Google Patents search. The search results also bring in materials from Google Scholar, Google Books and Google’s Prior Art Archive.
