Some of those companies lobbied for codification of the EPO’s software patent granting practices so it’s not surprising OIN won’t take part in the debate and it is clearly no friend of FOSS and innovation in general, contrary to the impression it sometimes gives.

And given its constituency and statements such as “Without the benefit of the exclusive rights conveyed by patents, it would be difficult to justify the risks inherent in the inventive process where substantial time or cost is involved.” etc. it seems likely its contribution to the debate would consist of reiteration of familiar fallacies and economically illiterate nonsense, so its absence is no bad thing.
