DEFINITION

Classification: 24/521

Having specific surface material or irregularity on or along engaging face:

(under subclass 489) Clasp*, clip*, or support-clamp* wherein

one of the gripping members includes either a specific, different substance or uneven surface formation forming the structure-to-be-secured* engaging surface of the gripping member.

(1) Note. Either a specific substance different in composition from that of its gripping member or details of the facial contour must be positively claimed for proper document classification herein as an original.

(2) Note. The facial contour may be either integral with, or on structure distinct from and attached to, the gripping member.

(3) Note. An engaging surface existing solely in a single plane formed along a curved, looped, or bent gripping member, is not considered to be irregular since it is not uneven in the gripping direction.
