Catchwords:

|
The assessment of inventive step can only be based on the
elements and aspects of the invention in respect to which a
technical effect can be established. Whether an invention causes
a technical effect is essentially a question of fact. While the
EPO has a duty to determine such facts in examination
proceedings, the onus is upon the applicant to cooperate in said
determination, in particular in the event of doubt (see point 7
of the Reasons for the Decision).
