Class 396
PHOTOGRAPHY
Class Definition:
GENERAL STATEMENT OF THE CLASS SUBJECT MATTER
A. This class provides for photos:graphic apparatus not
classified elsewhere, generally for recording a picture made
by a source of light on a photos:graphic medium.
B. This class also includes fluid-treating apparatus for
development of film.
C. This class will not receive for original placement a
patent claiming alternative embodiments, one of a type proper
for this class and one of a type related to another recording
class. Patents claiming alternative embodiments will be
placed in the class that provides for the alternative and
crossed in the appropriate subclass in this class. This class
will receive a patent disclosing two types of recording
devices when the claims are general or related to this
class.
D. Subcombinations of picture recording apparatus not
otherwise provided for, such as a removable film-holder unit,
hood, camera housing, and camera setting indicator or legend,
are classified here.
E. Also classified here are certain accessories related to
photography not otherwise provided for such as studio
structure (e.g., background, photos:graphic model, or
support, etc.), camera mounting or rest, camera attachment
(e.g., a vignetter), retouching, or burnishing device.
F. Nonchemical processes involving photos:graphic apparatus
of sections A-E, Class Definition, General Statement of the
Class Subject Matter, above (e.g., operating such apparatus)
are included in this class. See References to Other Classes,
below, for processes of radiation imagery chemistry.
LINES WITH OTHER CLASSES AND WITHIN THIS CLASS
Excluded from Class 396 is subject matter relating to image
recording of an original or carrier which is developed by
toner and video cameras utilizing a semiconductive or CCD
device. Such subject matter may be found elsewhere. See below
for the line between Class 396 and Class 348.
LINE BETWEEN CLASS 396 and CLASS 348
Class 396 will receive for original placement a patent
disclosing both Class 396 and Class 348 devices when the
claims are general or directed only towards Class 396 subject
matter and are otherwise proper therefor.
Class 396 will not receive for original placement a patent
claiming alternative embodiments, one of a type proper for
Class 396 and one of a type proper for Class 348. Such a
patent should be classified as an original in Class 348 and
crossed into the appropriate subclass in Class 396.
Similar placement applies to a claim reciting a combination
of Class 348 and Class 396 subject matter. The original is
classified in Class 348 with a cross to Class 396 except
where Class 348 subject matter merely provides a perfecting
feature of a Class 396 type camera or camera system. In that
case, the original is classified in Class 396.
(1) Note. Class 396, subclasses 429+ will accept a
combination of a Class 396 type camera and a diverse art
device where such combination is not otherwise provided for.
For classification purposes above, the recitation of an
"image sensor," "image pickup device," or the like that
generates an image representative electrical signal which may
be subsequently processed or displayed, or the positive
recitation of a "video camera" in a claim is considered to be
Class 348 subject matter if otherwise proper therefor.
OBJECT ILLUMINATION SUBCOMBINATIONS CLASSIFIED ELSEWHERE
Artificial light sources, per se, may be distinguished as
being either noncombustible or combustible.
Noncombustible incandescent lamps, where the filament is not
intended to be burned or consumed and for gas discharge lamps
of the "electronic flash" type are classified elsewhere. See
References to Other Classes, below.
The combination of a Class 313 light source and the
electrical circuitry for energizing the same are classified
elsewhere. See References to Other Classes, below.

explosive devices, such as rockets or dynamite are classified
elsewhere. See References to Other Classes, below.
The combination of an artificial light source with a
protector, support or distributor, and photos:graphic lights

structure are classified elsewhere. See References to Other
Classes, below.
(1) Note. This class (396) provides for a camera which
includes a detailed light-excluding case, casing, or housing.
See Subclass References to the Current Class, below.
FOREIGN ART COLLECTIONS IN CLASS 396
In establishing new Class 396, only a portion of the foreign
patents/nonpatent literature from old Class 354 was
reclassified along with the U.S. patents into subclasses
1-661 of the new Class 396 schedule.
Those Class 354 subclasses with foreign patents/nonpatent
literature which were not reclassified into subclasses 1-661
of Class 396 had these documents transferred directly to
equivalent foreign art collections maintaining their original
titles and positioning.
Those Class 354 subclasses with foreign patents/nonpatent
literature which were reclassified into subclasses 1-661 of
Class 396 have no equivalent foreign art collections. The
Class 396 subclasses having associated foreign
patent/nonpatent literature are as follows: 1-5, 14-47,
207-209, 246-256, 268-276, 281-296, 301-309, 322-350,
429-434, 438, 505-563, and 661.
The foreign art collections in Class 396 (subclasses FOR 700
- FOR 971) are intended only for receiving foreign
patents/nonpatent literature.
In subclasses 1-661, references to foreign art collections
under "SEARCH THIS CLASS, SUBCLASS" are intended only as a
guide and consideration should be given to the remaining set
of foreign art collections in completing a search.
Definitions of the foreign art collections were excerpted
from the corresponding Class 354 subclass definitions.
