Instantly uncover what your competitors are missing using NLPatent's intuitive AI-powered patent search platform. NLPatent's AI-first approach to patent search leverages large language models to understand innovation in a way that is only recently possible. Inform R&D strategy by quickly assessing novelty and inventiveness, leading to better-informed patent applications and decreased prosecution time. Quantify risk and defend against threats by effortlessly locating critical references that were previously missed. Go to market with confidence, armed with the intelligence required to de-risk product development and avoid infringing on existing patents. Describing your invention in natural language allows NLPatent to assess relevancy by conceptual similarity rather than blindly matching keywords. NLPatent is uniquely designed to optimize search outcomes through user-driven refinement based on known prior art and new results saved within the app.

Perplexity Patents is the world’s first AI-powered patent research agent designed to make intellectual-property intelligence accessible to everyone, replacing difficult keyword-based searches with natural-language prompts that retrieve and summarize relevant patents and prior art in real time. Unlike traditional tools, it supports conversational queries and surfaces inventions even when exact terms differ (for example, matching “fitness trackers” to patents covering “activity bands” or “health-monitoring wearables”). The system goes beyond patent databases by also exploring academic papers, software repositories, and other unconventional sources of prior art, and presents results in an integrated viewer with links to original documents. Behind the scenes is an advanced agent-based research engine that breaks down complex queries into retrieval tasks using a patent-knowledge index at a massive scale, and maintains context across follow-ups.
