Keywords
Late filed request - not admitted
Clarity (yes) - characterisation of a product solely by a combination of usual, directly characteristing parameters - not objectionable
Novelty (yes)
Inventive step (no) - product features expressing obvious desiderata obtained by obvious process modifications
Catchword
I. The characterisation of a product - here a fibre yarn - solely by parameters is not objectionable when these parameters are usual in the art and when they define positively various aspects directly characterising the chemical and physical nature of that product (point 5.4.2.2).
II. The questions of patentability are to be decided solely in accordance with the EPC. No national decision should be cited as if it were binding on the EPO; claims should not be refused by the EPO on the ground that their patentability could not be upheld under the jurisdiction of one member state (point 5.4.1).

ORDER

For these reasons it is decided that:

The appeal is dismissed.
