Who It's For

Why Legal choose this tool

🎯
Built for
It is best for IP professionals seeking to conduct rapid, comprehensive prior art searches and patent landscape analysis using contextual AI.
In-Depth Overview
For patent attorneys and IP litigators, NLPatent replaces cumbersome, keyword-dependent search processes with a sophisticated AI that understands invention concepts contextually. The platform claims an 80% reduction in time spent on patent searching, allowing legal teams to reallocate hours to higher-value strategic work. This efficiency is powered by a proprietary system of large language models, purpose-built by IP experts to navigate the complexities of patent filings. Unlike general-purpose AI, NLPatent is benchmarked across millions of searches and is shown to consistently find highly relevant prior art that other providers miss. This can be a 'silver bullet' in litigation, as one partner at Boies Schiller Flexner noted. Security is also paramount; the platform is SOC 2 certified, and client data is never used for model training. This combination of speed, specialized accuracy, and enterprise-grade security makes it a compelling tool for firms looking to gain a competitive edge in patent prosecution and litigation.
