Google has launched a new tool allowing anyone to search for US patents by keyword, patent number, inventor and filing date.
Users of the new site http://www.google.com/patents – can view a scanned image of the original patent and zoom in on pages. The main search page displays five different random patents each time the page is visited.
The US Patent and Trademark Office (USPTO) already allows anyone to search its site for patent documents, but Google’s offering may have some advantages.
The existing websites have patents that you can view so it is not that the information is not already there. The problem found by many users is that finding it and that is where Google has improved its search.
Google claims that like its web search technology, the patent search site uses a number of different signals to evaluate how relevant each patent is to a user’s query and then determines results algorithmically.
