DEFINITION

Classification: 560/96

Processes:

(under subclass 76) Processes for preparing compounds classifiable in that subclass.

(1) Note. When a patent contains claims to both a product classifiable in subclass 76 and a process, the patent is placed as an original in subclass 76 and cross referenced to this subclass. When the claims are directed solely to a process of preparing a compound classifiable in subclass 76, it is placed as an original in this subclass.
