DEFINITION

Classification: 522/2

Processes of forming or modifying a solid polymer by laser; or compositions therefore:

(under subclass 1) Subject matter involving the use of light amplified by stimulated emission of radiation, i.e., laser, or composition therefore.

(1) Note. This area provides for a specific wave energy process, i.e., laser. In order for a wave energy process to be classified herein as an original, there must be a claim to the noted process or the total disclosure in the patent must be directed to the specific process. The wave energy process in the claim need not be limited to the provided specific process if the claim specifically recites the process of this subclass. Processes not claimed or solely disclosed are classified below on some other aspect.

(2) Note. This subclass provides for compositions perfected so as to be utilized with a laser. See General Rules As To Patent Placement in the class definition.
