DEFINITION

Classification: 600/300

DIAGNOSTIC TESTING:

(under the class definition) Subject matter usable in medical evaluation of a condition of a living body.

(1) Note. As indicated in search notes appended to definitions of this subclass and subclasses indented thereunder, other classes specifically provide for certain devices usable in diagnosing a body condition. As also indicated in notes herein, a diagnostic device may be classified in one of the subclasses of Class 600 if a claim for the device includes some limitation showing that the device is specifically designed for use in evaluating a body condition but will be classified elsewhere if the device has disclosed utility for another purpose and is not claimed as aforesaid (e.g., an ultrasonic testing apparatus where no structure particularly adapted for placement on or in the body is claimed may be classified in Class 73, Measuring and Testing, subclasses 585+; or in Class 367, Communications, Electrical: Acoustic Wave Systems and Devices, subclass 87 where the apparatus is disclosed as having another utility in addition to medical testing utility).

(2) Note. This subclass includes methods and apparatus for diagnosis where the information obtained is for use by the diagnostician, whereas methods and apparatus including diagnosis incident to the operation or control of a surgical treatment apparatus are classified in the appropriate treatment subclass within Class 128 (e.g., a demand-type pacemaker which monitors the heart electric signal to trigger the pacemaker only when a heart arrhythmia occurs is classified in Class 607, subclasses 2+, and an intravenous infusion apparatus is classified in Class 604, subclasses 131+).

SEE OR SEARCH CLASS

340, Communications: Electrical,

573.1+, for alarms automatically responsive to the condition of a human being or animal (e.g., sleep inhibiting alarms).

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

2+, for a composition useful in medical diagnosis.

434, Education and Demonstration,

258, for a coordination testing device for testing a person's physical aptitude to perform a task, where no diagnosis of an abnormal physical condition is involved.
