DEFINITION

Classification: 523/105

Nonmedicated composition specifically intended for contact with living animal tissue or process of preparing; other than

apparel:

(under subclass 1) Subject matter wherein a nonmedicated composition having utility specifically intended to be in contact with animal living tissue is claimed or solely disclosed or to processes of preparation thereof other than apparel.

(1) Note. For an explanation of patent placement referring to claimed or solely disclosed, see (in the class definition) the section of SEARCH THIS CLASS, SUBCLASS that refers to this subclass.

(2) Note. The phrase "composition having utility specifically intended to be in contact with animal living tissue", refers to an intentional or desired composition which has been designed or formulated by specifically taking into account the contact of said composition with living tissue during the ordinary use for which the composition or ultimate article therefrom is made. The subclasses indented hereunder are presumed, absent specific assertions to the contrary, to lie within the meaning of this phrase.

(3) Note. Included herein are compositions utilized as adhesives for adhering textile materials to the skin, such as a nylon stocking, to prevent irritation to the skin. Excluded herein are adhesives which are not solely disclosed to come into contact with living tissue.

(4) Note. Living tissue is defined to be all internal and external tissue, including blood, except for hair and nails.

(5) Note. Apparel for purposes of this subclass is any material normally worn externally on the body for warmth or decoration and includes, but is not limited to, clothing, shoes, jewelry, etc.

(6) Note. Search Classes 523 and 524, in the appropriate subclasses for a nonmedicated composition specifically intended to come into contact with the body and wherein such contact is not solely disclosed. SEE OR SEARCH CLASS

8, Bleaching and Dyeing; Fluid Treatment and Chemical Modification of Textiles and Fibers,

160, and 161 for processes and compositions for removing hair or fur from a living animal body.

128, Surgery, appropriate subclasses for methods of treatment of the living body and apparatus used in the inspection and treatment of diseases, wounds, and other abnormal conditions of the bodies of men and lower animals; and for a composition used in sutures where the claim has either significant structure or a significant physical property characterizing said suture. The mere use of the terms "filament" or "fiber"

or suture, per se, is considered significant structure to be placed in Class 128. Numerical indices of tensile strength, handleability, sterility, density, or denier are other examples of significant characteristic physical properties proper of Class 128.

424, Drug, Bio-Affecting and Body Treating Compositions, appropriate subclasses for (A) a drug or bio-affecting composition capable of either (1) preventing, alleviating, treating, or curing abnormal and pathological conditions of the living body, (2) maintaining, increasing, decreasing, limiting, or destroying a physiologic body function, (3) diagnosing a physiological condition or state by an in vivo test or in vitro antigen-antibody test, or (4) controlling or protecting an environment or living body by attracting, disabling, inhibiting, killing, modifying, repelling, or retarding an animal or micro-organism; or (B) a body-treating composition generally intended for deodorizing, protecting, adorning, or grooming a body.

433, Dentistry, appropriate subclasses for methods, apparatus, implements, and devices relating to the treatment of teeth or gums or the replacement of teeth.

623, Prosthesis (i.e., Artificial Body Members), Parts Thereof, or Aids and Accessories Therefor, appropriate subclasses for artificial parts for a human body adapted to replace or supplement missing or defective body parts.
