Class 429
CHEMISTRY: ELECTRICAL CURRENT PRODUCING APPARATUS, PRODUCT,
AND PROCESS
Class Definition:
This class is the generic class for devices which produce an
electrical current by means of a chemical reaction or change
in physical state (e.g., from liquid to gas, etc.). Also
included are the following subject matter not provided for
elsewhere.
A. Structural combinations of the device, subcombinations
and elements thereof.
B. Electrolyte, compositions of the same, and process of
preparation.
C. Process of operating the device.
D. Miscellaneous process involving the device.
(1) Note. The meaning to be given to the various "art"
terms appearing in this class, but which have not been
included in the glossary below, is the same as that generally
accepted or in common usage. However, certain terms employed
in this class, which are included below, have been assigned
definitions tailored to meet the needs of this class and
therefore those may be more restricted or less limited or
even altogether different from those in common usage.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
A. LINES WITH AND SEARCH NOTES TO COMPOUND, COMPOSITION, AND
MATERIAL CLASSES.
1. A compound, per se, is classified in a compound class
regardless of utility. See References to Other Classes below
for an example of a class for inorganic compounds and
nonmetallic elements having a Class 429 utility
2. A composition or material, per se, (except for
electrolyte) for Class 429 subject matter is classified in
the appropriate composition or material class. Further, a
Class 429 article or product mentioned by name only (except
for separator) without any inclusion of structure and defined
only in terms of its composition or material is classified in
the appropriate composition or material classes, particularly
those listed below in References to Other 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.
a. The following guidelines are to be followed in
determining whether structure is present in any of the named
subject matter: (1) A recitation of any numerical dimension
of the product is deemed structure; (2) a product composed of
two or more layers is deemed structure; (3) randomly disposed
pores or cells in a porous, cellular or foamed product is
deemed structure; and (4) internal characteristics such as
crystalline form, molecular orientation, etc., is not
considered structure.
b. Once the determination has been made that structure
exists in the composition or material noted above and it is
singly disclosed or claimed for a battery, the patent is
classified in this class (429).
B. LINES AND SEARCH NOTES TO ARTICLE OR PRODUCT CLASSES
1. As a general rule an article is classified, the class
providing specifically for the same or a generic class which
can take the same.
An exception to this rule is an article mentioned in name
only and defined in terms of its composition or material is
classified in one of the composition or material classes.
(See "Lines With And Search Notes To Compound, Composition,
And Material Classes," 2, above, and References to Other
Classes associated with the above section.)
This class (429) provides for a battery combination
comprising a casing, electrodes and a separator. Also various
subcombinations of the above.
Usually the application or use of a current-producing device
(battery) in combination with other devices is classified in
appropriate classes. See References to Other Classes, below.
C. LINES WITH AND SEARCH NOTES TO PROCESS AND APPARATUS
CLASSES
See References to Other Classes below.
D. LINES BETWEEN CLASS 429, CLASS 204, AND CLASS 205
Wherein structure or process is common to both classes, the
following line is to be observed. Where combined subject
matter of both Class 204 and Class 429 is claimed or
disclosed, classification will be based on the proximate
function, e.g., current production, (Class 429) and the
production of a product (Class 204). Generic claims are to
be classified in the generic class (204). Also see the Search
Class notes below to Class 204 and Class 205.
