DEFINITION

Classification: 424/78.08

SOLID SYNTHETIC ORGANIC POLYMER AS DESIGNATED ORGANIC ACTIVE INGREDIENT (DOAI):

(under the class definition) Subject matter wherein the active ingredient is disclosed to be a solid synthetic polymer DOAI.

(1) Note. The term designated organic active ingredient (DOAI) denotes a polymer which imparts a physiological, pharmacological, or biological effect. Also, a solid synthetic polymer will be classified here, if it functions as a synergist or potentiator, i.e., one which will cooperatively act with an active ingredient to the extent that the total effect will be greater than the sum of the two individual effects. This subclass also provides for both the nominal methods of making and using the composition.

(2) Note. See Class 520, subclass 1, (7) and (8) Notes, for a more complete discussion of what is a solid synthetic

polymer. No weight is given to expressions designating molecular weight; e.g., 1,000, 40,000, or 4,000,000, etc., since these numbers can reflect solid, waxy, or liquid polymers alike.

(3) Note. Carbohydrates, polypeptides and cellulosic products and most of their derivatives are considered to be naturally occurring polymeric products. The exceptions to this are those which are found in Class 527; See SEARCH CLASS below. The synthesis of polypeptides in a random sequence; e.g., the use of N-carboxy-anhydrides of alpha-amino acids, etc., results in one which is considered proper herein when it is the DOAI and in Class 514, subclass 772.3, when it is not. The synthesis of polypeptides in an ordered sequence; e.g., the use of the Merrifield method, etc., results in one which is considered proper for Class 514, subclasses 2+, when it is the DOAI and in Class 514, subclasses 773+, when not. See Class 530, subclass 300, (1) Note, for a further discussion on this.

SEE OR SEARCH THIS CLASS, SUBCLASS:

400+, for a pharmaceutical or cosmetic composition containing a solid synthetic organic polymer which possesses some form or shape, or a specific dimension or configuration, or its components are associated as layers or parts.

SEE OR SEARCH CLASS 106, Compositions: Coating or Plastic,

35, for dental compositions devoid of a DOAI or a solid synthetic polymer.

128, Surgery, appropriate subclasses for appliances manufactured completely or partially from synthetic organic polymers.

427, Coating Processes,

2.1+, for coating processes wherein the base or the coating has medical or dental utility.

514, Drug, Bio-Affecting and Body Treating Compositions,

1+, for a composition containing both a designated organic active ingredient (DOAI) and a non-active solid synthetic polymer, subclasses 772.2, 772.3, and 788.1 for compositions devoid of a DOAI containing a solid synthetic polymer.

523, Synthetic Resins or Natural Rubbers,

105+, for non-medicated compositions for contact with living animal tissue and especially subclass 111 for compositions used to protect wounds, lesions, etc. The mere method of using these compositions for contact with living animal tissue is classified either in Class 424 or Class 514. The

following are examples of subject matter found in Class 523, subclasses 105+: (1) for manufacturing medical devices; e.g., blood bags, optical lenses, tubes, probes, cannulae, prostheses, catheters, surgical instruments, organs, etc.; e.g., from heparinized polyurethane, etc.; (2) for dental and body impression or filling compositions; (3) as an adhesive for bonding a textile to skin, surgical or medical dressings, etc.; (4) as a dental adhesive or cement; (5) for absorbing body fluids; e.g., sanitary napkins, etc.; (6)fFor manufacturing bandages; (7) as an osseous or bone cement for bone replacement or repair; e.g., one which contains hydroxyapatite, bio-active glass ceramic powder, crushed bone or particles of demineralized bone, calcium phosphate, etc.; (8) for slow release of pharmaceutically active agents (but not present).

525, Synthetic Resins or Natural Rubbers, appropriate subclasses for a solid synthetic polymer which has been chemically aftertreated with a chemical or drug intended for medicinal use; e.g., reacting a polymer with heparin, a glucoside with anticoagulant properties, etc.

527, Synthetic Resins or Natural Rubbers, for those synthetic resins which incorporate a naturally occurring material as a reactant; e.g., protein, carbohydrate bituminous material, etc. 604, Surgery, appropriate subclasses for medical devices manufactured completely or partially from synthetic organic polymers.

623, Prosthesis (i.e., Artificial Body Members), Parts Thereof, or Aids and Accessories Therefor, appropriate subclasses for prosthesis manufactured completely or partially from synthetic organic polymers.
