Patent amendment is not making a different claim
Yeda Research and Development Co Ltd v Rhone-Poulenc Rorer International Holdings Inc and Another
House of Lords
“When a reference was made under section 37(1)(a) of the Patents Act 1977 for joint ownership of a patent and the Comptroller-General of Patents, Designs and Trademarks was seised of the matter, an amendment to claim sole ownership of the patent did not amount to the making of a new or different claim.”
