Communication from the Enlarged Board of Appeal concerning case G 1/19

In accordance with Article 112(1)(a) EPC, Technical Board of Appeal 3.5.07 has referred the following points of law to the Enlarged Board of Appeal by interlocutory decision of 22 February 2019 in case T 489/14:

1. In the assessment of inventive step, can the computer-implemented simulation of a technical system or process solve a technical problem by producing a technical effect which goes beyond the simulation's implementation on a computer, if the computer-implemented simulation is claimed as such?

2. If the answer to the first question is yes, what are the relevant criteria for assessing whether a computer-implemented simulation claimed as such solves a technical problem? In particular, is it a sufficient condition that the simulation is based, at least in part, on technical principles underlying the simulated system or process?

3. What are the answers to the first and second questions if the computer-implemented simulation is claimed as part of a design process, in particular for verifying a design?
