DEFINITION

Classification: 427/2.1

MEDICAL OR DENTAL PURPOSE PRODUCT; PARTS; SUBCOMBINATIONS; INTERMEDIATES (E.G., BALLOON CATHETER, SPLINT):

(under the class definition) Processes in which the product is intended to be used for a medical or dental purpose, other than coating a living body, parts, subcombinations, or intermediates thereof or therefor.

(1) Note. Subject to the limitations and caveats of Class 427 definition, subject matter proper for this and indented subclasses includes the following:

(a)

processes which make a medical or dental product and which product is proper for placement in, or which product is intended for use in a process proper for placement in, Class 128 (including Classes 600, 602, 604, and 606), Class 424, Class 433, or Class 623;

(b)

other processes which make a product which is intended for, or which is intended for use in a process having, a clearly medical or dental use. For example, an in vitro diagnostic testing process or product (e.g., for bodily fluids) such as a test color-change strip or an immunoassay device, surgical gloves, gowns, or other apparel. See the Search Class notes below.

(2) Note. Coating of articles (not otherwise satisfying the definition of medical or dental products) are not proper herein when the coating is a biocide intended to preserve or

protect the article; such is classified elsewhere in Class 427 if significant coating is claimed, and otherwise is classified according to the article or composition preserved or protected. (3) Note. Coating a living body is not proper for Class 427; see Search Class notes hereinbelow that reference this note.

(4) Note. Search various appropriate subclasses elsewhere in Class 427 for significant coating of cosmetics, biocides, or other nonmedical, nondental compositions of Class 424.

(see the (3) Note above)

135, Tent, Canopy, Umbrella, or Cane, for staffs, crutches, stilts, etc., used as aids to walking but not adapted to be secured to the limbs.

subclasses 160+ for removable contact lens having specific optical characteristics for its use.

422, Chemical Apparatus and Process Disinfecting, Deodorizing, Preserving, or Sterilizing, for chemical apparatus which may have an in vitro medical use such as

50+, for analyzer, indicator, or lab device (subclasses 55+ for structured visual or optical indicators such as test papers, strips, or columns).

424, Drug, Bio-Affecting and Body Treating Compositions, for: compositions (A) for preventing, alleviating, treating, or curing abnormal and pathological conditions of the living body, for maintaining, increasing, decreasing, limiting, or destroying a physiologic body function, for diagnosing a physiological condition or state by an in vivo test, for controlling or protecting an environment or living body by attracting, disabling, inhibiting, killing, modifying, repelling, or retarding an animal or micro-organism, (B) for deodorizing, protecting, adorning, or grooming a body, (C) for fermentates and extracts for use in A or B and not elsewhere provided for, and (D) such compositions defined in terms of specific structure; methods of making the above compositions; methods of using the class-defined compositions for purposes in A and B; and methods of using per se compounds for purposes in A and B. Especially see

400+, for a composition defined in terms of specific structure having a utility for Class 424 and the methods of making which involve nonsignificant coating. (see the (3) Note above)

428, Stock Material or Miscellaneous Articles, for therein defined stock-materials (i.e., materials having no significant structure) of the subject matter of Class 433 or Class 623.

433, Dentistry, for methods, apparatus, implements, and devices relating to the treatment of teeth or gums or the replacement of teeth, or for methods normally performed by a dentist. See

217.1, for coating of natural teeth with adhesive or treating agent in the patient. Class 433 provides for the articles while Class 428 provides for the stock-materials. (see the (3) Note above)

434, Education and Demonstration, for apparatus and processes not elsewhere classifiable for providing instruction about a subject; or for means for displaying for purposes of comparison, contrast, or demonstration; or for demonstrating characteristics and advantages of apparatus, objects, or processes. Particularly, see
