Definition

STATEMENT OF CLASS SUBJECT MATTER

This class provides for compositions for treating living terrestrial and aquatic plants or their habitats for the purpose of stimulating or inhibiting growth, or any regulating action on plant growth, and the processes of using such compositions or compounds, per se, for such purposes which are not more than their mere application to the plant or habitat. The compositions or compounds included in this class will alter the plant growth through a chemical modification of the plant metabolism.

This class also provides for: (1) Seeds coated or impregnated with agricultural chemicals other than fertilizers, e.g., antidotes, plant growth regulators, micro-organisms, fungicides, disinfectants, etc. (2) Processes and their products which are of definite fertilizer value and are also insecticides, fungicides, or deodorants. These patents are cross-referenced to Classes 424 and 514. (3) Antidotal compositions, i.e., compositions which contain compounds capable of protecting cultivated plants from being damaged by herbicidal chemicals without affecting the herbicidal action of said chemicals against the weeds or unwanted plants to be controlled. (4) Soil life extenders, i.e., compositions which contain a herbicide and a compound useful for extending the soil life of said herbicide. (5) Compositions for preserving cut flowers. (6) Compositions for stimulating or increasing the sprouting of seeds, roots, tubers, or bulbs. (7) Compositions for regulating aquatic plants, particularly algae. (8) Compositions for regulating plant growth which use micro-organisms or products derived therefrom.

CLASSIFICATION GUIDELINES FOR THIS CLASS

In this class the chemical structure of the ingredient disclosed as having a utility set forth in the Statement of Class Subject Matter, above, is used as the primary basis of classification. Processes of using compositions or compounds, per se, and processes of making compositions, not provided for elsewhere are classified in the first appearing subclass providing for the particular active ingredient being employed or prepared.

The subclasses drawn to plural active ingredients include compositions which contain two or more active plant growth regulating agents, e.g., two or more herbicides.

No weight is given to a synergist or potentiator agent in classifying a composition for this class unless the synergist or potentiator agent is also an active plant growth regulator.

A patent claiming a Class 504 active ingredient broadly in terms of its function in combination with a specific adjuvant or carrier has been classified as original in the first appearing subclass providing for any one of the disclosed specific active ingredients and cross-referenced to all other subclasses providing for the remaining disclosed active ingredients.

Notes

(1) Note. Compounds included within this definition, but not considered organic are hydrocyanic acid, cyanogen, isocyanic acid, cyanamide, dicyanamide, cyanogen halides, isothiocyanic acid, fulminic acid, and metal carbides.

Lines with other classes and within this class

GENERAL GUIDELINES:

(1) Compositions which are disclosed as having a plurality of functions provided for in different main classes and only a single use, property, or function is claimed, are originally classified in the composition class providing for such claimed use, property, or function and cross-referenced to other classes for disclosed uses, properties, or functions when desirable.

(2) The rules for determining Class placement of the Original Reference (OR) for claimed chemical compositions are set forth in the Class Definition of Class 252 in the section LINES WITH OTHER CLASSES AND WITHIN THIS CLASS, subsection COMPOSITION CLASS SUPERIORITY, which includes a hierarchical ORDER OF SUPERIORITY FOR COMPOSITION CLASSES.

SEARCHING OF FOREIGN PATENTS IN THIS CLASS (504)

The foreign patents for subclasses 100 and 103-357 of Class 504 have been placed in the International Patent Classification System (in subclass A01N) and will be searched in that system according to its rules of classification.
