How Google Search Works With Patents
A typical Google query takes less than 1/2 second, but involves quite a few steps before you see the most relevant results. Here's how it all works.
Google Patent Search enables users to search the full text of the U.S. patent corpus and find patents that interest them.
All patents available through Google Patent Search come from the United States Patent and Trademark Office (USPTO). Patents issued in the United States are public domain government information, and images of the entire database of U.S. patents are readily available online via the USPTO website.
Using the same technology that powers Google Book Search, Google has converted the entire image database of U.S. patents into a format that’s easy to search. You can search the full text of U.S. patents from the Google Patent Search homepage, or visit the Advanced Patent Search page to search by criteria like patent number, inventor, and filing date.
Google and the USPTO have entered into an agreement to make bulk patent and trademark information available to the public at no charge.
Earlier this month, Under Secretary of Commerce and Director of the United States Patent and Trademark Office (USPTO) David Kappos announced that the USPTO has entered into a no-cost, two-year agreement with Google to make bulk electronic patent and trademark public data available to the public in bulk form. Under this agreement, the USPTO is providing Google with existing bulk, electronic files, which Google will host without modification for the public free of charge.
Director Kappos said the USPTO does not currently have the technical capability to provide this public information in a bulk machine readable format that is desired by the intellectual property (IP) community. This arrangement is to serve as a bridge as the USPTO develops an acquisition strategy which will allow the USPTO to enter into a contract with a contractor to retrieve and distribute USPTO patent and trademark bulk public data. The contractor will be capable of acquiring this bulk data and providing it to the public.
“The USPTO is committed to providing increased transparency as called for by the President’s Open Government Initiative. An important element of that transparency is making valuable public patent and trademark information more widely available in a bulk form so companies and researchers can download it for analysis and research,” said Under Secretary Kappos. “Because the USPTO does not currently have the technical capability to offer the data in bulk form from our own Web site, we have teamed with Google to provide the data in a way that is convenient and at no cost for those who desire it.”
“We’re happy to work with the USPTO to make patent and trademark data more accessible and useful,” said Jon Orwant, Engineering Manager for Google. “It’s important to make public data easier to gather and analyze. And when the data is free, that’s even better.”
Until now, the USPTO’s public data in bulk form has been provided solely as a fee-based service. The USPTO estimates that nearly ten terabytes of information will be made available through Google.
This has been described by intellectual property professionals as "good news and bad news." Good news that all this patent and trademark information previously available for a fee is now freely accessible. Bad news that it's only available in "bulk" form, which is less useful than it might otherwise be. It's also limited to United States Patent and Trademark data. So far, so good.
IP.com provides companies and intellectual property professionals with tools and solutions to more effectively manage their IP and innovations. Whether your objective is searching for patents or prior art, defensively publishing your innovations, obtaining research prior to applying for a patent or for other IP-related reasons, or realizing improved IP processes, IP.com has the right solution.
Our Intellectual Property Library website is a free international database of patent and patent-related publications. Our goal is to encourage worldwide access to resources where innovators can explore and understand patents, technologies, and related art. The database contains an ever increasing array of international patents (as published by the authorities) as well as non-patent literature (including our own Prior Art Database). The site features such things as full text and English translation searching along with unique "more-like-this" capabilities.
Start by Searching the Library or visiting the Library's Resource Center.
Like Google, IP.com's Intellectual Property Library is free.
