PatSeer is a patent search and intelligence platform from PatSeer Technologies, used by patent professionals, R&D teams and licensing groups. The site describes it as a hybrid of AI and expert search, where Boolean queries and semantic search run side by side. It reports more than 185 million patent records from 110 patent authorities, with machine translations and full text for most of them, and says more than 10,000 people use it.
AI features are spread across its editions. PremierPlus and ProX add AI Search, AI Summaries, Semantic Mapping and PatAssist, an assistant for questions about patents. PremierPlus also lists AI Refine and AI Recommender. ProX adds an AI Classifier that sorts patents and non-patent literature into categories in automatic or moderated mode and emails its prediction statistics. A Designs edition runs image similarity search over industrial designs, and the IP8 modules cover novelty, invalidity, freedom-to-operate, portfolio and monetization work, with novelty checks described as agentic AI.
No prices are published. The pricing page lists each edition with a contact form, so cost depends on a quote. A free trial is offered through the site, though its length and limits are not stated there.
