Headnote:

Where the inefficacy of a device or process forming part of the prior art is only recognised or alleged after the date of priority or filing, this cannot be cited in formulating the problem. This particularly applies where a problem of the "problem invention" type (cf. T 2/83, "Simethicone Tablet"/RIDER, OJ EPO 1984, 265) is used as an argument to show that an inventive step has taken place. The guiding consideration in assessing inventive step is the knowledge of the skilled person before the date of priority or filing (cf. point 5, paragraph 3, of the Reasons).

Relevant legal provisions:

European Patent Convention 1973 Art 56

Keywords:

Formulation of the problem where the inefficacy of a known device is only recognised after the date of filing
Inventive step (yes, after amendment of claims)
