Earlier this month, Google launched a new version of its Google Patents search engine. Like the previous version, the new Google Patents combines patent records from the United States Patent and Trademark Office (USPTO), European Patent Office (EPO), World Intellectual Property Organization (WIPO), Deutsches Patent- und Markenamt (DPMA), Canadian Intellectual Property Office (CIPO), and China's State Intellectual Property Office (SIPO). What’s different about the new Google Patents is that it uses a machine classification model to integrate Google Scholar’s non-patent materials, which are classified under the Cooperative Patent Classification System. This makes it easier to search for prior art across a wide range of sources, including books and technical journals. The new Google Patents also incorporates Google Translate to allow users to search foreign patent documents using English keywords.
