Sommaire

Whether a previously undisclosed technical effect which in fact inevitably occurs when a previously disclosed technical teaching in a written description is carried out has been made available to the public by reason of the teaching in the written description is a question of fact which has to be decided in the context of each individual case (consequential upon Decision G 2/88 of 11 December 1989 "Friction reducing additive/MOBIL OIL III", OJ EPO 1990, 93).
