Perplexity Launches AI-Powered Patent Search Tool Using Natural Language Processing

Perplexity's new AI tool lets you search patents with natural language - and it's free

Perplexity launched Perplexity Patents on Thursday.The new AI-powered database makes finding patents easier.You don't need specific language or codes to find patents. Patent searching is a lengthy, extensive, and imperfect process for innovators. If someone wanted to find patents in a certain area, they'd have to use several tools, like Google Patents, the United States Patent and Trademark Office, or a global patent database. Then, they'd have to search using specific keywords or codes -- or even rely on a patent attorney for supreme accuracy. Also: Why AI coding tools like Cursor and Replit are doomed - and what comes next Perplexity Patents, the AI company's latest tool, aims to not only democratize but also speed up that process. Released Thursday, the AI-powered database uses natural language to help researchers find the patents they're looking for. "Perplexity Patents ushers in a new era, in which anybody can access patent intelligence and get clear answers quickly, maintaining context across multiple questions," the Perplexity team wrote in a blog post. Perplexity Patents users can ask the database questions that don't rely on specific keywords or classification codes. For example, Perplexity said a user could ask Perplexity Patents, "Are there any patents on AI for language learning?" or "Key quantum computing patents since 2024?" for a more vague research approach, as opposed to using a carefully strung-together query with keywords and precise language. When a user prompts Patents, it uses Perplexity's patent knowledge index to return collections of patents and direct links to original patent documents. Also: You can now give NotebookLM more instructions - here's why that's a game changer If you ask the tool about one type of patent, it will also return answers to adjacent patents, compare different inventions, and enable follow-up questions, so users don't have to restart their search to learn more information. This means if you ask it about fitness trackers, Perplexity Patents will also return results on similar topics, like health wearables or activity bands. Want more stories about AI?

The tool will find prior art -- that is, any evidence of an existing patented invention in blogs, videos, code, academic papers, public software repositories, and other sources -- not just official patent databases. Perplexity Patents is currently in beta and free for all users. Pro and Max subscribers have more access to the model, alongside additional configuration options.

Perplexity launches AI agent for natural-language patent research

Perplexity has launched a new AI-powered patent research agent designed to simplify the traditionally difficult process of searching for patents. The new tool allows users to search patent databases using natural language queries instead of complex keyword strings. The company says users can enter conversational prompts, such as, "Are there any patents on AI language learning?" or "Key quantum computing patents since 2024," and the AI will return a list of relevant patents along with a generated summary for each one. The tool is designed to search beyond exact keyword matches, meaning a query for "fitness trackers" would also surface patents filed under conceptually similar terms like "activity bands," "step-counting watches," and "health monitoring watches." The AI agent also expands its search for prior art beyond patent databases to include academic papers, public software repositories, and other sources. Perplexity's new patent research tool is available for free to all users while it is in beta. Subscribers to the platform's Pro and Max plans will receive additional usage quotas and more advanced configuration options.
