After having a meeting with the patent attorneys, usually you will receive two documents to review – a Word document with texts and a PDF document with drawings.
Aside from using LLM to summarize the former, a good strategy to review the documents (without falling asleep) is to look at the drawings for a visual overview, and then read the high-level sections, like the abstract, the background, and the claims, before the detailed description when necessary.
You might find the legalese hard to understand even though they are supposed to describe your invention. This is expected, as the the patent is often worded as a defense against infringement, so just make sure that the claims are broad enough to cover your invention but not too broad as to be non-patentable.
