Patents and related documents

Description

Series includes approved patents for CG Sargent machines, patent files from competitors, and correspondence related to patents and copyright violation claims. Patents and correspondence relating to the C.G. Sargent's Sons Corporation were previously arranged by an unknown party, placing individual patents and correspondence related to that patent in envelopes. Each envelope is labelled with information about the contents therein, and a relevant "pack number" and "bundle number." The patents in this collection do not represent the complete number of items that were originally in these packs and bundles, which seem to have been arranged in chronological order by date of the patent filing. Much of the correspondence herein is incoming mail from patent solicitors or lawyers referencing patent filings by either the Sargent Corporation or their competitors. Also included is a bound book copy of Charles G. Sargent's testimony for the defense in a circuit court case, "Calvin L. Goddard and Charles E. Hoffman vs Francis Morris, Charles A. Bulkey and Robert W. Russell" regarding patent copyright violations.
