Sure. But if it's software: fuck off and use copyright. If people copy you, you're injured, you can show they copied you and obtain damages/injunctions. But if you want monopoly control over an idea, no matter who else comes up with it... that's rent-seeking.

Patents don't offer monopolies for fun, they're supposed to advance society by offering incentives for disclosure. The amount of incentive, and the likelyhood of non-disclosure was very different in the past, it certainly doesn't fit for computer software, so soceity shouldn't continue to offer that pact for computer software.

I don't know how I can be clearer about that. It's literally not allowed, and you think the first one you've looked at has somehow escaped the very direct statement that programs for computers are not patentable subject matter

Perhaps if you'll cite any of those French patents (I note you alluded to "over 300" but managed not to cite any), we can get started on the cancellations
