DEFINITION

Classification: 428/364

(under subclass 357) Product comprising a rod, strand, fiber or filament*.

(1) Note. A solid rod, fiber or strand product of uniform circular cross-section and extending in a straight line without deviation will not be considered for placement in this or an indented subclass. However, such a product, when coated will be considered as sufficient for subclass 375 even in the absence of structure. An impregnated fiber, strand, strand-portion, etc., unless qualified by structure (e.g., size, shape, etc.) will be considered as composition for the appropriate class (e.g., 106, 520, etc.; see (4) Note in subclass 357 and (2) Note below.

(2) Note. A patent to a rod, strand or fiber distinguished solely by its composition will be placed in the appropriate composition class. See particularly Class 106, Compositions: Coating or Plastic; see also; Class 520, Synthetic Resins or Natural Rubbers, for a synthetic resin or natural rubbers filament. For the purpose of patent placement in this subclass, the recitation of molecular orientation or crystalline structure in a fiber is not regarded as a structural limitation and patents claiming such fibers with no additional structure will be placed in the appropriate composition class. Also, a patent for a fiber where the presence of structure or the degree thereof is a mere manifestation of the composition will be placed in the appropriate composition class. A fiber defined in terms of its properties or other descriptors (e.g., tensile strength,

per cent elongation) is not considered a structurally defined fiber.

(3) Note. A patent directed to a rod, wire or filament of indeterminate length will be placed in Class 204, Chemistry: Electrical and Wave Energy, where a process under the definition of Class 204 appears to be a necessary limitation to the product. A product of a 157.15+ process will be classified as in the (2) Note above.

(4) Note. A patent for a strand consisting of woven constituents is provided for in subclasses 383+ of Class 139, Textiles: Weaving and a patent claiming a strand consisting of knitted constituents is provided for in subclasses 169+ of Class 66, Textiles: Knitting; however, a patent for a composite strand including either of such strands in combination with another unlike constituent (e.g., knit core with woven sheath) will be placed in this subclass 364 where not provided for elsewhere.

(5) Note. A patent for a composite rod or strand reciting or claiming at least one twisted or twined constituent will be placed in Class 57, Textiles: Spinning, Twisting, or Twining, but where said constituent is a preformed coiled spring element, the patent will be placed in subclasses 369+ below. See section VI Relation to Certain Other Classes, in the main class definition, reference to Class 57 for guide lines relating to placement of "yarns", "cords", etc. (6) Note. Excluded from this and indented subclasses are patents to one or more transparent elongated structures (e.g., rods, fibers or pipes) used to transmit light rays from one point to another within the confines of their outer surface, and involving internal reflections or modal transmission.

(7) Note. See (1) Note in the definition of subclass 36 for the distinction between a hollow strand, fiber or filament and a conduit type article.

SEE OR SEARCH THIS CLASS, SUBCLASS:

34.1+, for an article* (e.g., 3 dimensional or of substantial size) which is a cylinder or a conduit open at both ends and disclosed to conduct fluids and, disregarding the size, may be similar to a hollow fiber, filament or strand.

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

SEE OR SEARCH CLASS

2, Apparel,

256+, for strand or elongated rod-like element used as a stiffening or stay means for garments.

8, Bleaching and Dyeing; Fluid Treatment and Chemical

Modification of Textiles and Fibers, appropriate subclasses, for a monofilament of fiber which is the product of an operation provided for in that class.

14, Bridges,

22, for cable peculiar to the suspension of a bridge. 15, Brushing, Scrubbing, and General Cleaning,

208+, for an implement which includes rods, strands or fibers having particular shape, size or arrangement.

19, Textiles: Fibers Preparation, appropriate subclasses for drawing, carding or other fiber preparations involving no twisting.

26, Textiles: Cloth Finishing, appropriate subclasses for treatment of the constituents of a textile subsequent to fabrication of the product to obtain a better marketable condition.

28, Textiles: Manufacturing, appropriate subclasses for methods and apparatus for the mechanical interengagement of fibers.

52, Static Structures (e.g., Buildings),

720.1+, for an elongated rigid member specialized to use as or in in situ erected structures.

57, Textiles: Spinning, Twisting, and Twining,

200+, for a product reciting twisted or twined rod(s), strand(s) or fiber(s) and see (5) Note above.

66, Textiles: Knitting,

169+, for a knitted product not elsewhere provided for.

84, Music, 199, and 297+ for a musical instrument string.

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

1, 13 for a product embodying braided, knotted or intertwisted strands.

104, Railways,

240, for railway traction cable.

106, Compositions: Coating or Plastic, appropriate subclasses for a structurally defined fiber strand as provided for in that class (106) and see II under the class definition note of that class (106).

112, Sewing,

400, for a sewn strand (e.g., strand with stitches along its length).

131, Tobacco,

331, for stock material specified as being a filter and of indeterminate shape (e.g., mass) or approximating the shape (e.g., coil, tube, cylinder, rod) of the article or appliance with which it is intended to be used, requiring no further treatment than tearing or cutting to proper size; stock material of any other shape, recited so that some shape modification is required is classified in Class 428.

139, Textiles: Weaving, 383+, for a web or sheet claimed in terms of the particular arrangement or material(s) of the warp and/or weft; subclass 395, for a woven chenille strand; subclasses 457+ for method and apparatus for weaving a tubular or circular fabric; and subclasses 420+ for a woven textile possessing a certain texture resulting from the nature or form of the strands or fibers employed in the manufacture thereof.

204, Chemistry: Electrical and Wave Energy, especially

450+, for electrophoretic or electro-osmotic processes. Also, see the (3) Note above..

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions,

76+, 138+, and 152+ for a rod, wire, or filament formed by electrolytic coating processes.

213, for tie rods.

260, Chemistry of Carbon Compounds, appropriate subclasses, for a rod, strand or fiber, by name only, of a particular composition provided for in that class (260) and see (1) and (2) Notes of this subclass.

277, Seal for a Joint or Juncture,

For example, a pencil having a paper wrapping therearound is in Class 401, whereas a similar rod or strand with a paper wrapping, but with no coating implement feature would be proper for

377, below.
