This small collection illustrates the U.S. patent application process for a batting and pitching practice apparatus known as the "Pitchin' Pete." The collection consists of the documentation required by legal offices and the U.S. Patent Office, showing the procedure for taking the product concept through the manufacturing process, as well as affiliated expenses.

In September 1963, Burt met with patent attorney Norman S. Blodgett (1921-1991) and engaged his services in patenting his batting and pitching apparatus. There are letters from Blodgett to Burt on the patent application process.

Burt's notes articulate and illustrate the product specifications. There are legal receipts and letters from the inventor to Blodgett regarding legal bills incurred and fee-related questions. Burt's handwritten notes and letters contain questions related to licensing. There is a copy of the first advance payment of royalties. The batting and pitching practice apparatus patent is included in the collection, along with Burt's drawings, prior art, and product figures.

This collection would be useful to those interested in how a product concept develops from ideation through patent protection to manufacturing.
