Abstract

[Enclosure of D8954ADI] Dear Edison:-- re Lambrigot's anticipations. I enclose copies of letters from mar Hardingham my Patent Agent, regarding the Graphophone claim for cutting.##I am told that Conrad Cook's report on the Graphophone Patents, extracts from which were published in the Graphophone Syndicate prospectus I sent you, contained references to this case of Lambrigot's as published in the "Engineer" of about the same date, but although he tried to smooth It over as unimportant yet it was considered of sufficient importance for the promoters of the Graphophone syndicate to leave it out of their prospectus.##Wanted from America. Mr Hardingham says that it is important to know whethe there is in your United States Patent the same claim as contained in your English Case 86, viz:-- No 2 "The employment of a cutting style having a true cutting action"? If there is, he asks "was there any reference to publication in this connection brought forward by the United States Patent Office as alleged anticipation, and if so what?" He also says that it would be important to know what references, if any, were made in connection with the issue of the American Graphophone Patents. He thinks that it may probably be found that thet Patent Office did make refernce to the Lambrigot experiment. If so, that fact would have great weight here in showing that they made a claim in their British Patent in the face of knowledge of the prior publication in question. You have in your own possession information regarding any references to your own patents, perhaps you can get the information as regards references in connection with the Graphophone Patents. Yours sincerely G. E. Gouraud [marginalia: 393,967 [method?] 393968 [cutter?] 341214-- graph Bell Tainter4 May 4 86]
