Please read:
Welcome to the Unprocessed Patents page. It exists primarily for the search engines to index, and thus provide pointers for researchers to follow. Of particular importance is the light it sheds on U.S. audio patents issued before 1975 (marked with an ‘*’ on this page). These early patents can only be searched on the USPTO site by either patent number or current classification. This page can grow very quickly to point to thousands of pre 1975 patents and inventors and act as a guide to prioritize the full processing of the documents.
