> Patent texts read as prose, but are actually precisely structured legal documents.

at that point why not just use something precise like a programming language? have there been efforts in that direction? genuine questions

Yes (not patents in particular).

The name is "law as code".

(My impression: various approaches; mostly academic; some small companies in the space; judging from a loose assessment wrt my career choices as a freelancer: no real business opportunity yet)

I have no idea.

A few months ago, for the first time in my life, I had to write a patent document. It was very complicated – too complicated. Noting the structure, I searched for tools, but found only LLMs. So I wrote my own tool.

The amusing thing is, LLMs prefer the DSL-structured document!
