Patentable subject matter in the United States

Patentable subject matter in the United States is governed by 35 U.S.C. 101. The current patentable subject matter practice in the U.S. is very different from the corresponding practices by WIPO/Patent Cooperation Treaty and by the European Patent Office, and it is considered to be broader in general.
