Google has done it again! This time, they have expanded their excellent search capabilities to the US patent database. Although, currently they don’t include patent applications and international patents in their database, you can still search across 7 million issued US patents. Search results are ranked according to the relevance to the keywords used in the search. Advanced search options can be used to setup a complex query.
What I find particularly useful is a summary page for each patent providing all relevant details in a nice 2-column format. With a single click, you can see the patent summary with the picture of the first page, claims, drawings, citations and references. You can even search the full text of the patent for specific keywords. With citations and references easily available, it becomes very convenient to scan the related patents.
