# PatentBrief > Plain-English patent education and a growing database of landmark patents, with free interactive tools. Built so founders, inventors, students, and the curious can actually understand patents. PatentBrief explains what a patent is, what it does and does not cover, how to file one, what it costs, and how the system works — in plain English — and turns famous patents into short, readable briefings. The pages below are free and need no account. The complete machine-readable corpus — guides, 74 patent glossary definitions, 29 tool descriptions, and every plain-English patent brief in one file — is at https://patentbrief.org/llms-full.txt.
