Integrated high temperature method for oxygen production

Applicant name:

AIR PRODUCTS AND CHEMICALS, INC.

Opponent name:

Praxair Technology, Inc.

Board:

3.3.05

Headnote:

Although figures in examples may, under specific conditions, be used to limit a range, which was already present in the original application, they cannot be used to define an entirely new relationship between parameters which were never linked before. Such arbitrary new links between existing parameters introduce new matter, contrary to the requirements of Article 123(2) and 100(c) EPC (points 2.1 and 2.2).

Relevant legal provisions:

European Patent Convention 1973 Art 56
European Patent Convention 1973 Art 123(2)

Keywords:

Unallowable extension (main request and auxiliary requests 1 to 20) - creation of new parameters
Inventive step (auxiliary request 21) - yes, no incentive for the claimed solution of the problem in the prior art
