Patents: Patent Databases

Last Updated: Mar 21, 2022 3:49 PM

UB library staff are not able to provide any legal advice. This guide is purely for helping you learn about and search for patents. If you need legal assistance, please consult a licensed attorney. See the UB Patent Resources & Other Tools tab for more information on resources available to current students, faculty and staff.

Major Patent Databases

Five major databases are described below. The first four are freely available on the Internet. The Derwent database can be accessed only by UB patrons.

Special care should be used to determine the scope of each database.  Country coverage, starting dates, and searchable fields often vary within the same database depending on the country and the time period.
