#5Anyway. Software patents are generally unenforceable. This one is extra unenforceable. It's so weak that they won't even be able to play patent troll and bully small companies with it.
Also, I'm sure that somebody has already put in a request with the USPTO for an "Ex Parte Reexamination." This allows for a newly-granted patent to be challenged on prior art or patentability/obviousness grounds. The fee is something like $6000, so it's rare as most patents are hardly worth that much to begin with, but I could see it happening here.
In short, this was pointless on Mistral's part and a PR own-goal. Nobody else ought to be concerned.

#6Stateless? How is the recorded results not state?

#8> US 12,670,045 B1 was filed on 4 March 2026 and granted on 30 June. The claims are now readable and they are narrow: a stateless sandbox that pauses a code block, ships one tool call to the client, and resumes by replaying from the top. The prior art that bears on that is durable execution, not CodeAct.
This is really hard to parse! What's CodeAct? This article doesn't seem worth anyone's time. (it clearly wasn't worth the author's time to write it).
