DEFINITION

Classification: 435/4

Measuring or testing process involving enzymes or microorganisms; composition or test strip therefore; processes of forming such composition or test strip:

(under the class definition) Processes in which there is a direct or indirect qualitative or quantitative measurement or test of a material which contains an enzyme or microorganism or processes in which a material containing an enzyme or microorganism is used to perform a qualitative or quantitative measurement or test and compositions therefor and the processes of making such compositions.

(1) Note. "Involving" in this and the indented subclasses includes (a) the use of a known microorganism or enzyme to detect or identify a chemical compound or composition, (b) the use of a chemical compound or composition to detect or identify a microorganism or enzyme, (c) a composition containing a microorganism or enzyme for use as in (a), and (d) a composition distinguished by the presence of an indicator for use as in (b). Thus, "involving" in this and the indented subclasses means that the steps in the measurement or test either use the designated chemical compound, microorganism, or individual plant or animal cells or enzyme or the steps in the measurement or test indicate the presence or absence of the designated chemical compound, microorganism, plant or animal cell or enzyme.

(2) Note. The enzyme herein can be free or immobilized or present in a cell, tissue, or organ.

(3) Note. Compositions herein may include inert carriers

that have either a single or multiple zones or chemical agents. Included as carriers are bibilous or absorbent materials and films.

SEE OR SEARCH THIS CLASS, SUBCLASS:

174+, for immobilized enzymes, per se.

183+, for enzymes. 188, for stabilized enzymes, enzyme conjugates or compositions thereof.

235.1+, for viruses, per se.

287+, for apparatus for measuring and testing.

73, Measuring and Testing, for processes and apparatus for making a test or measurement of any kind not provided for in other classes. In general, the classes superior to 73 are 435, 422, 424, 204, 350, and 356.

128, Surgery, for methods of treatment of the living body or a test which involves contact with a body and apparatus used in the inspection and treatment of diseases of the bodies of men and animals which apparatus is provided with means for connection to the living body.

137, Fluid Handling,

2+, for processes of controlling the flow of a fluid in response to the sensing of a condition or characteristic of a fluid.

204, Chemistry: Electrical and Wave Energy,

400+, for electrolytic analysis and testing apparatus, especially subclass 403 for electrolytic analysis and testing apparatus involving biological material (e.g., microbe, enzyme, antigen, etc.).

205, Electrolysis: Processes, Compositions Used Therein, and Methods of Preparing the Compositions,

775+, for electrolytic analysis or testing processes, especially subclasses 777.5+ for electrolytic analysis or testing involving an enzyme or microorganism (e.g., animal or plant cells, bacteria, virus, etc.). 208, Minerals Oils: Processes and Products, for chemical tests claimed in association with processes for recovery or treatment of naturally occurring mineral oil.

252, Compositions,

408, for testing compositions.

260, Chemistry of Carbon Compounds, for chemical tests claimed in association with processes for the treatment or modification of carbon compounds.

324, Electricity: Measuring and Testing, appropriate subclasses for methods and apparatus for testing an electrical property or condition of a material by electrical means, even though the result of the test may be used as an indication of some other physical or chemical property or condition.

346, Recorders,

2+, for phenomenal apparatus and processes recording.

356, Optics: Measuring and Testing, especially

28, 139.04 through 139.08, 141.1 through 141.5 and 152.1 through 152.3, 205+, and 218 for methods and apparatus for optical testing with a photoelectric light detector with either an indicator or structure to support or contain the specimen or sample under test. Class 356 provides for methods and apparatus for visual counting of bacteria colonies, etc., with a scale or spacer to aid the eye without an optical element or statistical analysis procedures for the sizing and counting of particles, such as bacteria colonies by visible light and the counting of particles one by one with a microscope having a graticule rather than a cross hair or reticle.

359, Optics: Systems (Including Communication) and Elements,

396+, for transparent microscope slides with means to contain and support the life functions of a microorganism. 364, Electrical Computers and Data Processing Systems,

496, for data processing systems or calculating computer designed for use in chemistry, chemical engineering or other areas of engineering or for the solution of problems in these areas.

377, Electrical Pulse Counters, Pulse Dividers, or Shift Registers: Circuits and Systems,

10, for sizing or counting of discrete particles such as bacteria colonies one at a time by numerical counting apparatus which registers the counts.

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

1.11+, for class defined compositions and methods comprising a radionuclide or intended radionuclide, including those for in vivo diagnosing, and subclasses 9.1+ for a composition or method of in vivo testing (diagnosing) a living body or for

an in vivo method of testing or analyzing a composition of that class (424).

436, Chemistry: Analytical and Immunological Testing,

1+, for processes for analysis involving steps for causing or promoting a chemical reaction, regulating or controlling a chemical reaction. This includes tests dependent upon the chemical, i.e., proteinaceous reactivity of an enzyme as opposed to its catalytic functioning provided for in Class 435. Measurements and tests when claimed in association with chemical processes provided for in other Classes, e.g., 435, 208, 260, 423, etc., are classified in the class providing for the chemical process.
