[D8370A], Letter from Thomas John Handford to Edison Electric Light Co, Edward Hibberd Johnson, January 1st, 1883
Editor's Notes
Rcd yours of 14 Ult. Re: the "unfortunate" Delarrey(?) matter, sorry you don't want to proceed with patents as the money I've spent in that direction will be thrown away; Gouraud won't pay, says it's your affair. Regarding my own business, my connection with TAE has not been an unmixed good, as might have been expected---it frightens away other electrical people, who don't trust I can advise them impartially. Rec'd from Dyer the important applications to which you refer; thanks for your recommendation. Waterhouse, like you, thinks the final specs and claims for these should be settled by Counsel but think my long experience drawing up specs would be preferable. Haven't heard of misgivings of Co's scientific advisors. Think claim of No. 5 patent is too broad. You can't claim carbon filament of high resistance, as advantages of high resis already well known, as were advantages of carbon. Think the actual invention TAE should've claimed is the carbonizing of a vegetable material to obtain such a filament; this would have resulted in a patent. PS "I find the new points in the important applications just received are very fine & it will be exceedingly difficult to base valid claims upon them."
