DEFINITION

Classification: 424/9.1

IN VIVO DIAGNOSIS OR IN VIVO TESTING:

(under the class definition) Subject matter which includes compositions intended for use in in vivo testing or in vivo diagnosis and nominal methods of using compounds or compositions for in vivo testing or in vivo diagnosis.

(1) Note. Claims which include in vivo diagnosis or in vivo tests as merely incidental to the treatment of a patient are classified in one of the appropriate treatment subclasses below.

(2) Note. In vivo, for this and the indented subclasses, means the actual test or diagnosis step must occur in or on the living subject.

(3) Note. In a plural step test procedure, if the actual analysis step takes place in vivo, the test method is classified in this or the indented subclasses. If the actual analysis step takes place in vitro, no matter how many other steps in the method involve in vivo treatment or administration, the test method will be classified in another class appropriate for such an in vitro test method.

(4) Note. Included herein are methods of determining the efficacy of a bioaffecting compound or composition.

(5) Note. These subclasses (424/9.1+) provide for plural step in vivo diagnostic procedures which utilize bioaffecting compounds or compositions wherein one of the steps is no more than a mere statement of nuclear magnetic imaging, x-ray imaging, ultrasound imaging, etc. of a living body. Class 128 provides for such tests if a more detailed manipulative step of nuclear magnetic or ultrasound imaging is included. Diagnostic x-ray imaging may be found in Classes 128 and 378 depending on the test details recited. A reading of the definitions for those classes is recommended for proper placement of the subject matter.

SEE OR SEARCH THIS CLASS, SUBCLASS: 1.11+, for diagnostic radioactive compounds or compositions or nominal diagnostic methods of utilizing such radioactive compounds or compositions.

73, Measuring and Testing, which is the generic class for making a measurement or test of any kind not provided for in other classes.

250, Radiant Energy, for methods of detecting radiant energy

252, Compositions,

408.1, for compositions which do not chemically react in use and are specialized and designed for use in physical analysis, testing or indicating, or as a warning agent.

324, Electricity: Measuring and Testing, as the residual home for measuring and testing electrical properties or the measuring, testing, or sensing of nonelectric properties by electric means, but only when absent a significant chemical reaction.

356, Optics: Measuring and Testing, provides for analyzing light to measure or test its characteristics, determining the optical or nonoptical properties of materials or articles by noting the effect produced by the materials or articles on light associated therewith, etc.

378, X-Ray or Gamma Ray Systems or Devices, for apparatus and corresponding processes involving the generation or use of electromagnetic radiation within the X-ray spectrum. Mere use with or attachment to an X-ray device or recitation of an undefined X-ray test or analysis is not sufficient for classification in Class 378.

426, Food or Edible Material: Processes, Compositions, and Products, provides for processes where a condition in preparing an edible is sensed by other than subjective means.

435, Chemistry: Molecular Biology, and Microbiology, 4+, for in vitro measuring or testing involving enzymes or micro-organisms, subclasses 7.1+ for blood typing, protein binding, ligand-receptor binding, and immunological assays, subclasses 29+ for testing involving a viable micro-organism, and subclasses 40.5+ for testing involving fixed or stabilized, nonliving microorganism, cell, or tissue.

436, Chemistry: Analytical and Immunological Testing,

1+, for chemical test standards and their use and the qualitative or quantitative analysis of chemical compounds, complexes, and elements which at some point involve a chemical interaction (see Class 436, CLASS DEFINITION, I. for further explanation) and subclasses 500+ for in vitro immunological or protein binding assays other than those involving a micro-organism or enzyme.

600, Surgery,

300+, for an appliance and its use to aid in the diagnosis of a disease or abnormal condition of the body and subclass 556 for skin allergy tests.

800, Multicellular Living Organisms and Unmodified Parts Thereof and Related Processes,3, for a method of using a transgenic nonhuman animal in an in vivo test method.
