Applicant name: Jalon, Michel
Opponent name: GAO
Board: 3.3.01
Headnote: 1. When examining for inventive step using the "problem and solution" approach, the starting point for defining the appropriate skilled person is the technical problem to be solved on the basis of what the closest prior art discloses, irrespective of any other definition of the skilled person suggested in the contested patent.
2. Since the technical problem addressed by an invention must be so formulated as not to anticipate the solution, the skilled person to be considered cannot be the appropriate expert in the technical field to which the proposed solution belongs if this technical field is different to the one considered when formulating the technical problem.
3. The appropriate skilled person's basic knowledge does not include that of a specialist in the different technical field to which the proposed solution belongs if the closest prior art gives no indication that the solution is to be sought in this other technical field.
