I guess the purpose of patents is to "protect" *actions* people can perform - eventually to make money. That is the true purport of the famous Cochrane v. Deener decision in 1876 (which was misunderstood as requiring a "machine or transformation")
Probably the single most famous patent decision by the German Federal Supreme Court is the "Red Dove" case. The patent was rejected because the breeding process was deemed not to be *repeatable*.
I think it makes sense to require an *action* and to require it to be *repeatable*.
