What We Do
NLPatent is an industry leading AI-based patent search and analytics platform trusted by Fortune 500 companies, Am Law 100 firms, and research universities around the world. The platform takes an AI-first approach to patent search; it's built from a proprietary Large Language Model trained on patent data to truly understand the language of patents and innovation. Users simply describe their invention in full sentences and conceptually relevant results are generated instantly; consistently outperforming human experts on speed and accuracy. The system is simple, intuitive, and iterative. Best of all, it explains the relevant sections of each patent it identifies, removing the "black box" often experienced by other AI-based platforms.
