Milwaukee Public Library is an official Patent and Trademark Depository Library. A Patent and Trademark Depository Library (PTDL) is a library designated by the U.S. Patent and Trademark Office (PTO) to receive and house copies of U.S. patents and patent and trademark materials, to make them freely available to the public, and to actively disseminate patent and trademark information.
Once a month, a librarian from the Business and Technology Department presents a free workshop on how to conduct a patent search. Please call 414-286-3051 if you have any questions.
