Paste any patent number and instantly see which country issued it and what its kind code (A1, B2, U1...) actually means — no lookup, no waiting, works entirely in your browser.
A patent number's own structure tells you where it was filed and what publication stage it represents — a granted patent, a pending application, a utility model — purely from the format of the number itself, before you look anything up. This tool decodes that structure instantly, entirely in your browser.
It does not tell you whether the right is still active, who owns it, or what it actually covers — for real, verified data on a specific number, use Patent Check or Patent Mapper.
