DEFINITION

Classification: 428/375

(under subclass 364) Product in which the rod, strand, fiber or filament is (1) partially or completely covered with a material or (2) is structurally defined as set forth in the definition of subclass 357 and, in addition, may also be partially or completely saturated or permeated with a material or adhered to another material or strand, fiber or filament or rod or contain a central portion.

(1) Note. A patent directed to a product including a wrapped constituent* will be placed in this subclass; however, a patent directed to such product will be placed in subclasses 139+ of Class 57, Textiles: Spinning, Twisting, and Twining, where it is claimed that said constituent is wrapped progressively along the length thereof (i.e., coiled)

(2) Note. A patent for a strand formed by a knitting or

weaving operation and coated, impregnated or covered after completion of said operation will be placed in this subclass.

(3) Note. A patent directed to a strand including a twisted or twined constituent and further including an encircling sheath formed by an extrusion process will be placed in this subclass (375).

(4) Note. The term "sized" or "sizing" will be construed as a coating and will be placed in this group of subclasses, unless it is clear than only an impregnation is intended.

(5) Note. Attention is directed to section V of the class definition: Guidelines for Placement of Patents Having no Significant Structure. A patent having a claim to a coating material and also a claim to a product of a rod, strand or fiber coated with this material and in which the product claim includes details of the coating material, is classified in the appropriate composition or compound class in the absence of recited structure (e.g., dimension, shape, etc.). Cross-referencing into this Class 428 of such patents from the appropriate compound or composition class (e.g., Class 106, Class 260, etc.) has been kept to a minimum. For a complete search, the other pertinent class should be considered. SEE OR SEARCH THIS CLASS, SUBCLASS:

98+, and 221+, especially the subclasses so entitled for a coated or impregnated web* or sheet* comprising rods, strands or fibers or for coated rods, strands or fibers forming elements* of a web or sheet.

615+, for corresponding metallic* stock-material*.

SEE OR SEARCH CLASS

8, Bleaching and Dyeing; Fluid Treatment and Chemical Modification of Textiles and Fibers, for a fiber product of a process provided for in that class and especially

114+, and 115.51+ for a product of the chemical modification of a textile or organic fiber; subclass 115.6 for such product which further includes a coating, size or lubricant, and subclasses 495+ for a fiber dyed and impregnated.

57, Textiles: Spinning, Twisting, and Twining, 258+ especially

258+, for a coated or impregnated rod or strand comprising a twisted or twined constituent (as claimed) and including such product regardless of whether the constituents thereof are coated or impregnated before, during or after assembly thereof to form the product.

87, Textiles: Braiding, Netting, and Lace Making,

1, for a strand product of that class, whether the constituents thereof are coated or impregnated before, during or after the braided strand with a core. Also See section VI A 1 a (3) of this definition.

132, Toilet, 93, (dental floss), for strand structure impregnated with an abrasive material(s).

174, Electricity: Conductors and Insulators, for a product which conducts electricity and is coated or covered with a dielectric, where the product includes (1) some structure of the conductor specifically designed to conduct electricity or (2) some structure of the dielectric especially designed to space conductor either from ground or from a device of different electric potential.

204, Chemistry: Electrical and Wave Energy,

450+, for electrophoretic or electro-osmotic processes. Also, see section VI, B, of the class definition of Class 428.

277, Seal for a Joint or Juncture,

537, for a dynamic seal of composite construction, having a distinct sheath or covering, contained or compressed by a gland member in a packing box, or subclasses 652+ for a static contact seal for other than internal combustion engine, or pipe, conduit or cable having a distinct sheath or covering.

313, Electric Lamp and Discharge Devices,

345, for a coated filament or electrode; and subclasses 352+ for a cored, coated or laminated composite electrode.
