There is a version of AI for legal work that is mostly a chat box bolted onto a document store. It can summarise, rephrase and answer general questions, and for a while that feels like progress.
The trouble is that intellectual property work is specific. A response to an examination report is not a summary task. Classifying goods and services is not a paraphrase. The value sits in knowing which deadline cannot move, which objection is fatal and which is routine, and what a particular examiner tends to accept.
Tools that are built for the domain encode that. They know the shape of the work, the data behind it and the consequences of getting it wrong, so the output is something a professional can act on rather than something they have to check from scratch.
That is the line we care about. Generic tools save a few minutes on the easy parts. Purpose-built tools take on the parts that actually consume the day.
