Public and Free Patent Search Resources
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.
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.
These are the official databases of the USPTO. 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.
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.
This is a search tool that is available only inside Central Library. PubEAST is also used by patent examiners at the USPTO in Alexandria, Virginia. This resource provides access to all patents issued in the U.S. and applications issued since March 2001.
Public and Free Trademark Search Engines
The Trademark Electronic Search System (TESS) can be used to search federally registered trademarks.
The state of Indiana’s database can be searched to see if a trademark/service mark is being used by anyone locally.
Other Trademark Resources
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.
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.
