DEFINITION

Classification: 205/687

Electrolytic material treatment (product, process, and electrolyte composition):

(under the class definition) Subject matter directed to the chemical modification of material by electrolysis, including products thereof where not provided for elsewhere and electrolyte compositions for use therein.

(1) Note. For this subclass and the subclasses indented hereunder, some of the terms in the schedule and definitions are defined as follows:

Platinum group metal: A metal element from the group

consisting of osmium (Os), iridium (Ir), platinum (Pt), ruthenium (Ru), rhodium (Rh), and palladium (Pd).

(2) Note. The processes in this section of subclasses are intended to provide for electrolytic purification, concentration, or another desirable modification of an element, compound, or composition of matter; as distinguished from electrolytic synthesis of a desired element or compound, found in subclasses 334+. When a starting material is electrolytically altered and then electrolytically reconstituted the process is classified as electrolytic synthesis.

67+, for electroforming processes and compositions therefore.

80+, for processes intended to produce a permanent coating on a substrate by electrolysis. 640+, for electrolytic erosion resulting in a change of workpiece shape or surface configuration.

775+, for electrolytic methods of analysis or testing, per se. See the (1) Note in subclass 775.
