Brief outline of the case
For the OD, the invention defined in claim 1 of the main request (= as granted) was not sufficiently disclosed. The set of claims according to AR 1 was found allowable.
The OD maintained the patent on the basis of AR 1 and in particular, considered claim 1 of AR1 to involve an IS over D10 (not in the ISR/EPO) as CPA.
