Case No. IP-2018-000199

35.The experts agreed that the skilled person’s common general knowledge would have encompassed a variety of both permanent and temporary fasteners. 36.In paragraph 6 of the Amended Grounds of Invalidity Airbus pleaded a list of matters which formed part of the common general knowledge. Save in relation to the E-Nut, the list was not challenged. 37.With regard to the E-Nut, Mr McKay said in his report that he had never come across it by the filing date and he was not challenged on this. In crossexamination Mr Jack accepted that it was a reasonable opinion that the E-Nut was not well known by 2008. I find that the E-Nut did not form part of the common general knowledge.
