With Google Patents you can search and read the full text of patent grants and applications from around the world. If you're looking for prior art, you can use the integrated Prior Art Finder tool and Google Scholar documents to find patent and non-patent prior art, all in one interface. Google Patents includes patent applications and grants from the USPTO, EPO, WIPO, DPMA, CIPO, and SIPO. Patents without English full text are machine-translated to English, so you can search foreign patent documents using only English keywords. Documents from Google Scholar have been classified with Cooperative Patent Classification (CPC) codes using a machine-classification model to make it easier to search non-patent literature in a patent searching context.
