Partial Input handling and a results UI are easy to build, but judging whether patent claims are supported by evidence requires patent-law expertise and reliable access to comprehensive prior-art records.
What it would actually take: Use USPTO and public patent APIs, plus web and non-patent literature search, with an LLM that extracts claim elements and maps them to evidence. The hard parts are the claim-construction logic, which needs a patent attorney's review to avoid misleading conclusions, and full-text coverage of prior art, which may need paid databases such as Google Patents bulk data or commercial indexes.
