DEFINITION

Classification: 428/357

(under the class definition) Product containing, or consisting of, at least one strand*, strand-portion*, macroscopic fiber*, grain, small bit of matter, cell*, particle* or any other substance, claimed in terms of (1) a particular size or shape (natural or fabricated), (2) a plurality of such elements* claimed in terms of an arrangement relative to one another, (3) a particular interengagement of a plurality of such elements* or (4) a coating associated therewith.

(1) Note. The molecular orientation or crystalline structure of a product is considered a mere manifestation of the nature of the material thereof; accordingly, the recitation of either is not considered structure within the meaning of that word as used in this subclass.

(2) Note. A patent directed to a single layers or mass* of a particular composition which is further defined as "cellular", "particulate" or "porous" (by name only), will be placed in the appropriate composition class in the absence of defined structure (see above clauses in the definition of this subclass).

(3) Note. A patent to a structurally defined particle will be placed in this, or the appropriate indented subclass as a subcombination of the subject matter provided for herein, unless specifically provided for elsewhere.

(4) Note. Excluded from this or indented subclasses is a rod, strand, fiber or filament which is merely impregnated with or has associated therewith a material, without any specified indication as to the depth of the impregnation, or without any other recited structure; such a combination is classified on the basis of the composition, e.g., for Classes 106, 260, 520, etc.

(5) Note. The term "sizing" or "sized" will be construed to be a coating for this group of subclasses unless it is clear that only an impregnation is intended; see (4) Note above. (6) Note. A mass of fibers merely bonded together with no recitation of structure, is excluded from this Class 428 and will be found in the appropriate composition class; see search notes below.

(7) Note. The term "flake" is construed as structure, indicating a flat piece of matter.

(8) Note. Included under this definition of "significant size" is any recitation of a measurable extent, no matter how wide (e.g., up to 0.5 mils, etc.).

SEE OR SEARCH THIS CLASS, SUBCLASS:

221, for a web* or sheet* of fibers or filaments* which are claimed as being bonded at their intersections.

292.1+, for a composite* web or sheet in which one component* contains fibers.

323+, for a composite* web or sheet in which one component contains particles which are structurally defined.

48, for a roll cover, per se, and see the notes thereunder.

520, Synthetic Resins or Natural Rubbers, for a synthetic resin or natural rubber composition containing an ingredient which may be coated, impregnated, or has a defined size or shape.

521, Synthetic Resins or Natural Rubbers,

50+, for a synthetic resin composition (or single layer) in cellular form.

588, Hazardous or Toxic Waste Destruction or Containment,

249+, for containment of hazardous or toxic waste.
