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 Patent Public Search 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.

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.

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.

Intellectual Property Basics and Helpful Resources
These training opportunities from the U.S. Patent & Trademark Office (USPTO) will be conducted via live videoconference calls in 2024 on:

• October 3
• November 7
• December 5

These live online trainings will all occur from12-1 p.m. Eastern Time. Registration is required through the USPTO’s Eventbrite page. The events are free and open to the public.

The USPTO’s Midwest Elijah J. McCoy Regional Outreach Office located in Detroit will be providing these instructional sessions.

Entrepreneurs and innovators who are unfamiliar with patents, trademarks, copyrights, and trade secrets can register for these presentations to learn about how these forms of intellectual property can be used to protect products and innovations. The presentations will also emphasize the importance of protecting intellectual property, and resources available through the USPTO and other agencies will be discussed.

Request an Appointment

A library staff member can provide a demonstration on how to conduct patent and trademark research and help connect you to information related to intellectual property. Call the library at 317-275-4100, press 4 from the list of extensions, and ask to speak with the Patent and Trademark Resource Center Representative or patent librarian to schedule an appointment.

The library cannot conduct legal research for you or provide any legal advice. Consult an attorney if you need this type of assistance.

Pro Bono or Free Legal Help

There are nationwide programs that provide inventors and entrepreneurs with pro bono or free assistance in drafting and filing patent and trademark applications. In the state of Indiana, there are law school clinics where law school professors and students can be matched up with inventors or entrepreneurs to provide assistance. The professors typically supervise the students throughout the assistance process. Some of the nationwide law school clinics can also provide assistance to applicants who do not live in the state where the law school is located.

One of the requirements for applicants to be accepted into these programs is an annual income level that is below 300% or 3 times the federal poverty guidelines. For example, a single person can have an income level below $40,770 and meet the income requirement for the law school clinics. This income amount of $40,770 is 3 times the 2022 federal poverty level of $13,590 for a one-person household in the 48 mainland states and The District of Columbia.
