Statutory subject matter - sustany/dvg GitHub Wiki

To qualify as patentable subject matter, an invention must satisfy two criteria: statutory, and judicial.

35 U.S.C. Section 101, requires that to qualify as statutory subject matter, the subject matter of the invention must fall into at least one of five categories:�

1. Compositions of matter (compounds such as a drug or glue);
2. Articles of manufacture (simple devices such as screwdrivers and rakes);
3. Machines (devices with moving parts, such as an auto engine);
4. Processes (a method of doing something such as an implant procedure); and
5. New and useful improvements of any of the above categories.

Judicial subject matter means that subject matter cannot fall within an exception recognized by the courts.
