The. history of the matter. has been conveniently summarised. in the deoisiot;l un4er r~yi~w
and 1 quote it verbatim:_ "In 1936 as a re:sultof pulblicity in thetechni.cal press concerq;pg
" a: process for the m~nufacture of regenerated· protein· fibres' which had peen develop~<,L Py

" Messrs. Courtaulds became interested in this process, and wishing to be able to manufl;lcture
"regenerated protein fibres by the best available prdcess they entered' into negotiations -With
" Snia' Viscosa. In consquence of these negotiations an agreement was reached in -July ,_ 1931..
"with that company wher~by Snia Viscosaundertook to obtain for Messrs. Courtqulds'4iil
" exc1usiv ~ 'licence under certain .patents inclUding the patent· in. suit. This' agreement;whi61l

"necessary technical information to carry out the proceSs covered by the patents and alsg
"provides that Messrs. Snia Viscosa would obtain for Messrs. Courtaulds free excluslve
"licences UIKler any patents which might be granted either in Great Britain or. Canada: to
"Messrs. Snia Viscosa or to Mr. Ferretti in connection with the process for the mariufactfu:~
"of regenerated protein fibres. The consideration for the a!oove matters was fixed at £15,000
"which was to be paid '!is soon as the above-mentioned teohnical information was furnished.
" The agreement also contained provisions relating to the payment of royalties on the amount

"Courtaulds' representatiyes. includiIl!g a' chemist and a textile technologist, visited. the
"factory of Snia Viscosa in Milan where the Ferretti process was shown to them in operatipn
"and they received the technical information, including particulars of the step which forms
"the subject"llllatter of the patent in suit, required by Messrs. Courtaulds in order tbit a
"similar plant could be installed and operated by them at Coventry. The sum of £15,OQQ
"was paid in 1937. With the aid of the information received from the visit of their repi'e,; sentatives to Milan, Messrs. Courtaulds proceeded to erect a pillot ,plant in Coventry which
"was completed in 1938 and was in almost continuous use from 1938 to 1947. The operatibrt
"of this plant involved the use- of the step which forms thesllibject-matter: of patent No. 511,160'.
"It is'particularly to be noted, however, that'no attempt was made by Messrs. Courtaulds··to
"require Messrs. Snia Viscosa to implement the clause in the agreement of 1937 relating to
" the granting to Messrs. Courtaulds by Mr. Antonio Ferretti of an exclusive licence to, Qperate

"a clause purporting to cause the licence to have taken effect from 2nd November, 1939.
