SECTION I - CLASS DEFINITION

This class is the residual locus of means and processes for casting visible radiant energy in at least one direction to render objects in that direction visible.

BASIC SUBJECT MATTER OF THE CLASS

The basic subject matter of the class is comprised of:

A. The combination of a source of visible radiant energy and means to modify the distribution or composition of the radiant energy emanating from the source.

B. Methods utilizing the combination of A, above, to cast light in at least one direction to render objects in that direction visible.

SCOPE OF THE CLASS

In addition to the basic subject matter of the class, this class also provides for:

A. Subcombinations of the basic subject matter of the class not provided for elsewhere comprising:

1. means to modify the distribution of composition of light from sources other than the heavenly bodies;

2. means to support a source of visible radiant energy;

3. means to support the modifying means of item 1, above, and

4. combinations of items 1, 2, and/or 3, above.

B. Combinations of the basic subject matter of the class and subject matter classified elsewhere insofar as the combination is not provided for elsewhere.

C. Accessories to the basic subject matter of the class limited in their intended use to the basic subject matter of the class.

(1) Note. Wherever drawings are associated with subclass definitions, they are used merely to illustrate the basic concept encompassed by the definition of that subclass and should not be construed as limiting the scope of the subject matter covered by that subclass.

SECTION II - LINES WITH OTHER CLASSES AND WITHIN THIS CLASS

A. LIGHT SOURCES, PER SE

Light sources, per se, are not classifiable in this class (362). For such devices, see References to Other Classes, below.

B. LIGHT MODIFIERS

Generally, light modifying means, per se, used merely to modify light from light sources other than a heavenly body are classifiable in this class (362). For exceptions listed in this class, see Subclass References to the Current Class, below.

Light modifying means not limited in use to illumination are not classifiable in this class. Two such modifying means may be found in References to Other Classes, below: (1) Filter, i.e., means to modify the composition of light, not limited in use to illumination; and (2) reflectors, refractors, etc., i.e., means to modify the distribution of light, not limited in use to illumination.

C. LIGHT SOURCE SUPPORTS OR HOUSINGS

This class (362) provides for combinations of a support for a light source and significant structure of a light source and for a light source support having structural features limited to use with a light source. Housings for light sources having more than nominally recited light source supporting means or having or comprising light modifier means of this class type are also provided for in this class. For light source housings, per se, and certain types of light source supports, see References to Other Classes, below.

D. SIGNALLING AND COMMUNICATION

Illuminating means, per se, which are used to convey information (e.g., "signal lanterns") are generally classified in this class (362) unless explicitly provided for elsewhere.

Means to convey information classifiable in another class combined with illuminating means is generally classified in the other class. Classes providing for such combinations may be found in References to Other Classes, below.

E. COMBINATIONS OF DEVICES PROVIDED FOR IN OTHER CLASSES AND ILLUMINATING MEANS

Combinations of devices provided for in other classes and illuminating means are classified with the device unless specifically provided for in this class (362) whether or not the illuminating means illuminates the device itself. See the search notes of the combination subclasses of this class (362) for the lines between this class and other relevant classes.

Classes providing for combinations of devices of the respective class type and illuminating means may be found in References to Other Classes, below.

F. SPECIAL APPLICATIONS

In general, the proximate function of the basic subject matter of this class (362) is merely to direct visible radiation in at least one direction to render a reflective object in that direction visible to an observer in the path of the light reflected from the object.

Illuminating means used to perform functions provided for in other classes are classified in such classes. See References to Other Classes, for class references to subsection D, above, for classes providing for illuminating means used in signalling and communication. Additional classes also providing for illuminating means used in performing the function of the classes may be found in References to Other Classes, below.

340Communications: Electrical,   appropriate subclasses for claimed combinations whose proximate function is to convey information by means of electrically generated visible light. Such combinations must necessarily include a light source or light source and modifier and some (encoding) means which establishes a correspondence between the distribution, composition or location of the light and some other fact to be communicated. This requirement is based on the premise that, in signalling with visible light, the light itself is merely the carrier of or medium for the transfer of information and not the information itself. If the proximate function of the claimed combination is to convey information and illuminate or to convey information or illuminate, the combination is classifiable in this class (362). Subcombinations of subject matter of this class (362), for example, a light source and modifier which can be used for signalling (e.g., "signal lantern") or is used for signalling in nonclaimed disclosure, are classified in this class (362), unless explicitly provided for in Class 340.

SECTION V - GLOSSARY

The following definitions of terms occurring frequently in the titles and definitions of this class are intended only to be used as aids in determining placement of subject matter within this class and do not necessarily encompass all usages of the terms in the art. Because the following definitions are generalized, certain subclass definitions may include definitions of the listed terms which deviate somewhat from the definitions given below. In such cases, the subclass definition is controlling. The use of ambiguous or equivocal art terms in the titles and definitions of this class has been avoided wherever possible. For the interpretation of such terms for classification purposes, see the notes to the definitions of "Modifier."

FILTER

A type of transparent or translucent selected wavelength modifier which absorbs light of at least one wavelength (i.e., color) and transmits light of another wavelength.

ILLUMINATING MEANS

Basic subject matter of the class or subcombinations thereof.

LIGHT SOURCE

An element (e.g., filament) or material (e.g., neon) which converts energy into visible radiant energy and/or the essential container of such an element or material, i.e., a light source envelope including the envelope base (e.g., light bulb, fluorescent tube). Unless otherwise specified, a light source is assumed to be a point source. For purposes of classification within this class, nominal recitations such as "light unit," "lamp," "headlight," etc., are assumed to denote only a light source.

MODIFIER

A recited element or combination of elements whose proximate function in the claimed combination is, according to the claim or the claimed disclosure, to alter the distribution or composition of light emitted from a light source by reflecting, refracting, or partially or completely absorbing the light.

(1) Note. Certain terms such as "lens," "shield," "screen," etc., are used in the art in some instances to denote modifiers and in other instances to denote structure whose proximate function is other than to modify light. For example, the term "lens" is used in some instances to denote means whose proximate function is to refract light and in other instances to denote merely a transparent window in a light housing whose proximate function is to protect the light source. Whether or not a means recited in a claim in such ambiguous terms is to be considered a modifier for placement within this class must be determined by the proximate function (according to the claim or the claimed disclosure) of the means in the claimed combination.
(2) Note. Certain terms such as "shade," "bowl," etc., are used in the art in some instances to denote recited modifiers which, according to the claim or claimed disclosure, function to modify light in two or more ways provided for separately in this class. A recited "bowl," for example, may, according to the claim or claimed disclosure, function in the claimed combination to diffuse light by internal scattering within the material of which the bowl is made (viz., translucent bowls) and reflect light from one of its surfaces. Such a modifier is classifiable in the first-occurring subclass providing for modifiers which perform at least one of its modifying functions.

REFLECTOR

A light modifying device having a surface which redirects incident light back into the medium from which it came. Reflectors are more commonly opaque but may be transparent. Light incident on the redirecting surface of a transparent reflector may arrive from the transparent material of the reflector itself in which case it is redirected back into the transparent material of the reflector, or it may arrive at the redirecting surface from some other material (e.g., air) in which case it is redirected back into the other material. Whether a recited transparent modifier is a reflector or some other type of modifier or both depends, for purposes of classification within this class, on its proximate function according to the claim or claimed disclosure.

REFRACTOR

A light modifier whose proximate function is to redirect light comprising a light pervious material having a pair of opposed surfaces, at least one of which is, at least in part, so angularly related to the other surface that the path of a light ray incident on one opposed surface of the material and the path of the same ray after it emerges from the material through the other opposed surface are not parallel. A nominally recited "lens" is considered a refractor for purposes of classification within this class only if the structural and functional characteristics of a refractor can be imputed to it from the claim or claimed disclosure. (See (1) Note to the definition of "Modifier," above).

SELECTED WAVELENGTH MODIFIER

A type of modifier which modifies light of at least one wavelength (color) differently from light of another wavelength. Such modifiers may reflect, refract or filter light.

TRANSLUCENT

Having the property of certain light pervious materials which results in the random internal scattering of light rays passing through the material.

TRANSPARENT

Having the property of certain light pervious materials which permits light rays to pass through the material in straight lines. Transparent illuminating means may or may not be light modifiers.

(1) Note. In this subclass and those indented hereunder are placed patents whose claims all relate to the illuminating features to be applied to a body component and such combinations with modifications of the body merely for the promotion of illumination. If novelty is claimed in the body or component structure with which a source of light is combined, which novelty is independent of the illumination, the patent is classified with the other body.
(2) Note. In this subclass and those indented hereunder, support elements for a light source or unit which do not also function as supports for components of the stationary body or building are not considered body components for placement in this section. That is, structure which has no other purpose than that of supporting a light source is not considered a static structure component for this section.
(3) Note. Class 52, Static Structures (e.g., Buildings), takes building structure including features having functions in addition to merely supporting the illuminating means or forming the enclosure, barrier or other structure illuminated. In interpreting this line, the presence of a claim to building structure not including illuminating means is considered conclusive of the fact that such additional function features are present.

(1) Note. Included in the subject matter of this subclass is, for example, a light source comprised of a continuous fluorescent surface of revolution generated about a nonlinear axis since the rays of light emitted by such a light source, if extended inwardly, all meet on the nonlinear axis which thus constitutes the virtual curved line light source of this subclass type.
(2) Note. The light source of this subclass type are either recited as being curvilinear or as in combination with means whose recited structure and function necessarily recognize the curvilinearity of the light source. Thus, a filament type light source is not necessarily classifiable here even though the filament may be disclosed as being curved.

(1) Note. Light sources of the type provided for in this subclass and the subclasses indented hereunder are usually recited as "tubular," "elongated," "linear," "cylindrical," and "extended." In all other cases, the elongated nature of the light source must be implied by the claims themselves or necessarily imputed from the claimed disclosure in order to render the claimed combination structurally complete and operative for the functions referred to in the claim. For example, "means to support a pair of fluorescent lamps" is sufficient basis for placement in this subclass or the subclasses indented hereunder even though fluorescent lamps are often elongated since the word "fluorescent" itself does not imply length. On the other hand, "means to support a pair of lamps parallel to each other" is sufficient basis for placement in this subclass or the subclasses indented hereunder since the word "parallel" implies that the lamps have length.

 This subclass is indented under the class definition.  Subject matter comprising combinations not elsewhere provided for of basic subject matter of the class, including subcombinations thereof, with additional means whose proximate function in the combination does not contribute to the efficacy (i.e., intended proximate function) of the class type subject matter.
(1) Note. This subclass constitutes the residual locus for the combination of illuminating means with the object being illuminated. For example, the combinations of a light source and a modifier bearing locomotive identification numbers are classified here since, even though the modifier is class type subject matter, the function of the indicia is, primarily, to express information about the locomotive and only secondarily to modify the light from the source by altering its distribution. Mere combinations, however, of light sources and colored lenses, for example, to be used as signaling means are not classified here since such combinations only constitute basic subject matter of the class. Also, combinations of illuminating means and signalling means which conveys information about the illuminating means are not classified here since the proximate function for the signaling means (i.e., to convey information) contributes to the efficacy of the illuminating means.

(1) Note. Nominal recitations of a light unit (e.g., "light unit," "headlight," "lamp") generally imply only a source of light and are insufficient basis for placement in this subclass and the subclasses indented hereunder unless a light source and a light modifier must be imputed from the claimed disclosure to render the claimed combination structurally complete and operative for the functions referred to in the claim.
(2) Note. Light sources having light modifying envelopes are not classifiable, per se, in this class (362). (For the loci of such subject matter, see the search class notes below).

[List of Patents for class 362 subclass 382]    382SUPPORTS:
 This subclass is indented under the class definition.  Subject matter comprising structural means to position, by itself or in combination with some other disclosed means, a light source or modifier with respect to some reference point or reference structure.
(1) Note. The "reference structure" of this subclass may be included in the "structural means" of this subclass or it may not. The "reference structure" or "reference point" need not be on an element recited in the claims for structure of this subclass type to be classifiable in this subclass or the subclasses hereunder.
(2) Note. The line between this class, subclasses 382+ and Classes 248, Supports and 439, Electrical Connectors, is as follows: Class 362, subclasses 382+ takes any combination of a support with significant structure of a light source or a light source support having structural features limited to use with the light source. Class 248 takes supporting structure, per se. The mere naming of a light source, as in the preamble of a claim or in any other way which does not positively include it as an element of the claim, will not operate to take the claim out of Class 248 unless the support itself is an essential part of the light source or has no obvious utility as a support in some other art classes. See Class 248 definitions, (2) Note, for lines between this class (362) and Class 248. Class 439 takes an electrical connector, per se. The mere recitation in a claim of a light source, which is not claimed as being connected to or mounted in the electrical connector, will generally not operate to take the claim out of Class 439. If an electrical connector in name only is claimed with supporting means which is not limited in use to a Class 362 light source, the claim is classifiable in Class 439. A detailed electrical connector (e.g., a claimed contact) with or without a support therefor, claimed with a light source in name only is classifiable in Class 439. If a detailed electrical connector is combined with a support which has structural features limiting the combination to use with a claimed light source, even if claimed in name only, the claim is classifiable in Class 362. See Class 439 definition, section III (1) and (2) for lines between this class (362) and Class 439.
