Comic actor Danny Kaye received patent D166,807 for the co-design of "Blowout Toy or the Like". It's similar to one of those toys that unravels when you blow into at a birthday party except Kaye's has three blowouts going in different directions, not just one.

STATEMENT OF CLASS SUBJECT MATTER

This class provides for the following subject matter when not provided for elsewhere:

A. A process of using a microorganism or enzyme to synthesize a chemical product.

B. A process of treating a material with a microorganism or enzyme to separate, liberate, or purify a preexisting substance.

C. An in vitro process of measuring and testing in which: (1) A microorganism or enzyme is used to determine the presence or identity of a compound or composition in a sample; (2) A microorganism is identified by propagation; (3) An enzyme is identified by its catalytic activity; (4) The presence of microorganisms is detected; (5) A live microorganism is used in an antigen antibody test as an antigen; (6) Fixed or stabilized nonliving microorganisms, cells, or tissues are involved.

D. A process of propagating a microorganism.

E. A process in which the genetic structure of a microorganism or extrachromosomal genetic structure is altered.

F. A process of organ or tissue maintenance.

G.A process of mashing or malting.

H. Apparatus claimed or solely disclosed as for A-G.

I. Microorganisms, per se, or the subcellular parts thereof.

J. Enzymes, immobilized enzymes or enzyme containing compositions not otherwise provided for and the processes for purifying enzymes or forming immobilized enzymes.

K. Compositions claimed or solely disclosed as for the propagation of microorganisms or for measuring and testing processes in C above.

L. Using microorganisms to destroy hazardous or toxic waste.

CLASSIFICATION GUIDELINES FOR THIS CLASS

APPARATUS

This class takes only apparatus claimed or solely disclosed as for fermentation or enzymology, organ, and tissue maintenance or genetic engineering not otherwise provided for. Apparatus by name only which is claimed as a collection of compounds or compositions in a kit without structure is classified as described below in Lines With Other Classes and Within This Class.

COMPOSITIONS

In general, this class will not provide for compositions other than an immobilized or insolubilized enzyme or a test or culture media.

COMPOUNDS

In general, this class does not provide for compounds other than an immobilized or insolubilized enzyme or an enzyme, per se. Production of metal or ammonium salts of a compound are classified with the production of that compound.

AMINO ACID RESIDUES

If upon hydrolysis of an unidentified product the only residues are amino acids, it should be presumed that the product is a protein or peptide. If other organic moieties are present after hydrolysis of the product then placement should be made upon the basis of the presence of such structure in the product.

PRESUMPTION

In the absence of a clearly claimed step of killing or inactivating a microorganism in an antigen-antibody test the microorganism should be treated as a living antigen.

Lines with other classes and within this class

See References to Other Classes, below, for lines with classes providing for the use of a microorganism, an enzyme and the apparatus therefor and the composition classes providing for the products of a microorganism or enzyme and for lines with other related classes.

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.
