DEFINITION

Classification: 585/301

Using same catalyst, solvent, inert heat carrier, or

component thereof:

(under subclass 300) Subject matter wherein a catalyst, solvent, diluent or inert heat carrier, or a material which makes up a part of such substance is used in one of the parallel syntheses, its use in such synthesis is discontinued, and the catalyst etc., or component thereof is used in the other parallel synthesis.

(1) Note. Use of identical extraneous materials in both parallel syntheses is not sufficient for placement of a patent in this subclass.

(2) Note. Where both parallel syntheses use an extraneous agent drawn from and returned to a common pool or reservoir, the patent is placed here.
