Jackson Hunsicker (1948-2017) invented the Memo Mate in the mid-1990s. It was a small personal recording device that could store up to twenty seconds of audio. The Memo Mate was marketed as a handy way to remember appointments, phone numbers, directions, and the location of a car in a large parking lot. The Memo Mate was a successful invention, selling close to 10 million units. Hunsicker's papers on the patenting and marketing of Memo Mate document the typical process and pitfalls of patenting and marketing by a lone inventor. The collection consists of the legal correspondence of the patent application process and subsequent contractual disputes, along with schematics and designs, and possible names and logos. Hunsicker’s invention represents a demonstration of the patent process as well as a contribution from a woman inventor to the field.
