- Patent Classification

- USPTO Kind Codes
The combination of letters and numbers at the end of a granted patent or patent application is called a kind code. Kind codes tell you what sort of patent document you're reading: a patent application, a grated application, the country of origin of the patent application or granted patent, and the sort of item patented: a plant patent, design patent, and so forth. The link will take you to a list of kind codes used by the USPTO.
