Florida Patent Depository Library
Patent depository libraries are an excellent resource for patent research. The United States Patent & Trademark Office has established around 80 depository libraries throughout the United States with at least one in each state. Many states have several. For example, Florida has two patent depository libraries in South Florida, one in Miami and a second one in Ft. Lauderdale.
Broward County Main Library
Miami-Dade Public Library
A third patent depository location is in Orlando, Florida:
University of Central Florida Libraries
A comprensive listing of patent depository libraries is available by visiting the U.S. Patent & Trademark Office Library Listing Page.
These libraries all have extensive collections of issued patents that can be searched. Many of them have qualified department staff who can help you with any questions or problems you are having. For instance, I am aware that the patent depository library in Ft. Lauderdale, Florida offers patent search classes at no charge.
