This folder contains correspondence to and from Edison's patent attorneys, along with other correspondence relating to patent applications, patent litigation, and other patent matters. Included also are other patent-related documents, such as patent applications, caveats, preliminary statements, and a few printed patents. There is also a set of drawings by William Carman relating to the telephone interference cases and a list of notebook pages that were used as exhibits in these cases (see Thomas A. Edison Papers, Part I (1850-1878)).
Approximately 90 percent of the documents have been selected. The following categories of documents have not been selected: duplicate copies of correspondence; printed copies of Edison's U.S. patents (see http://edison.rutgers.edu/patents.htm); copies of Edison's claims; other inventors' claims, specifications, and patents; correspondence and other documents concerning non-Edison patents, except when they relate directly to Edison and his work; routine bills and receipts from patent attorneys; routine correspondence from patent attorneys regarding accounts and fees.
