How Patents Actually Work

A patent grants a 20-year monopoly from filing in exchange for public disclosure of the invention. It is territorial: a US patent stops nothing in Japan. It protects products, not ideas: you must describe a concrete, useful, novel, non-obvious implementation.

Since 2013 America files first-to-file, ending the race to prove earlier invention. Provisional applications hold a date for a year. Enforcement is up to the owner: courts, damages, injunctions.

The system trades secrecy for disclosure, aiming to speed the learning curve of the whole world..
