Some of the most popular free patent databases in the world are , , and http: //www.surfip.

We will briefly discuss in this article how you can conduct a Free Patent Search in USPTO database. This is the first of the seven articles that we will write to teach any one to use USPTO website to conduct patent search.

USPTO database contains over 33 million patent documents and is updated every week. The website is probably the largest patent website in the world. It provides a free patent search facility for both beginners and advanced users.

How can I conduct Patent Search at USPTO?

The answer to this question is given in a technical way in many websites. We will try to avoid the jargon and we will try to enable even a layperson that is not exposed to search databases regularly to do it easily.

The USPTO deals with conducting a Patent Search using its freely searchable patent database through the Internet. The instructions are given at The USPTO stresses the importance on 7 Steps each one to be done one after the other.

The Patent Search website has started a patent training course online. We can train you online wherever you live and the lessons and exercises are sent on a daily basis for three weeks. We teach a simplified version of methods to our students using Free Patent Databases. Although a paid database is more users friendly, the official free databases are updated with regular data and the expensive paid databases take some time (a short time) to update themselves to be current. Therefore it is necessary to conduct a search in the official free patent databases online even after using paid patent databases. A proper training and search strategy for free databases is therefore very important.

One problem is that the USPTO does not allow you to do the free patent search on patents granted prior to 1976 unless you start the patent search with the class and sub class alone. So you need to identify the classes and then do a patent research of pre 1976 patents also.
