Public and Free Patent Search Resources

Espacenet
This resource is provided by the European Patent Office (EPO). U.S. and worldwide patents can be searched using this tool. Espacenet has information about inventions dating back to 1836.

Google Patents
This search engine is great for beginning a patent search and contains patent information dating back to 1790. Patent documents found in this resource should also be searched in PatFT/AppFT or Espacenet to make sure the most current versions have been located.

Patent Public Search
Patent Public Search is now available through the U.S. Patent and Trademark Office’s website. This new searchable database is the official replacement for PubEAST, PatFT, and AppFT. Patent Public Search allows for searching of pre-grant applications from March 2001-Present and full-text U.S. patents from 1970-Present. The database does contain some searchable scanned patents before 1970 and searching for some of the earliest patents dating back to 1790 can only be done using classification and patent number searching only.

PatFT/AppFT
PatFT contains full text U.S. Patents from 1976-Present. Patents issued prior to 1976 can only be searched by issue date, patent number, and current U.S. classification. AppFT contains full text patent applications from March 2001-Present. PatFT and AppFT will be discontinued in late September of 2022. Patent Public Search is the new replacement search database for PatFT and AppFT.

Lens
This resource contains information on U.S. patents from 1976-Present, U.S. Applications from 2001-Present, and patent information from the EPO, World Intellectual Property Organization, and some Australian patent documents.

PubEAST
This is a search tool that is available only inside Central Library. This resource provides access to all patents issued in the U.S. and applications issued since March 2001. PubEAST is also scheduled to be discontinued in late September of 2022.

Public and Free Trademark Search Engines

The Trademark Electronic Search System (TESS) can be used to search federally registered trademarks.

INBiz
The state of Indiana’s database can be searched to see if a trademark/service mark is being used by anyone locally.

European Union Intellectual Property Office (EUIPO)
TMview is a database managed by the EUIPO that has trademark information from 66 trademark offices including the USPTO.

Type your idea for a trademark into search engines like Google, Yahoo!, Bing, or Amazon to see if other companies are using the name for a product or service. This particular technique is good for finding unregistered trademarks.

Other Patent and Trademark Resources

Manual of Patent Examining Procedure (MPEP)
The Manual of Patent Examining Procedure provides instructions and guidelines regarding the overall examination and prosecution of patent applications that have been submitted to the USPTO. Patent examiners who review the patent applications submitted by inventors and their attorneys or patent agents are required to follow these guidelines when reviewing the applications. Inventors and their attorneys or agents who draft the application are also required to follow the guidelines presented in this manual.

Trademark Manual of Examining Procedure (TMEP)
The TMEP can be used to learn about and search for the practices and procedures the USPTO follows pertaining to trademarks.

Trademark ID Manual
Trademark applicants can add an international class number to their application for an identified good and/or service. The trademark ID manual allows you to search for the correct number. These international class numbers can be used to search for trademarks in TESS as well.

Design Search Code Manual
Each image or design that is trademarked is assigned a design code. These trademarked designs are categorized by a six-digit number. This manual can be used to identify a code to search in TESS.

Virtual Training

Patent, Trademark, and Intellectual Property Training
The USPTO offers free virtual training sessions from their headquarters in Alexandria, Virginia and through their regional offices across the country. Entrepreneurs, inventors, and people with a general interest in intellectual property are encouraged to sign up and participate in these free online sessions, which are scheduled throughout the year.
