Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 313: Electric Lamp And Discharge Devices

This is the generic class for electric lamp and electric space discharge device structure. Examples of such devices are electric incandescent lamps, gas or vapor filled electric discharge tubes, including lamps, mercury arc devices, vacuum discharge tubes, radio tubes, cyclotrons, cathode-ray tubes, photosensitive discharge devices, secondary emission electron multipliers, spark plugs, and open air arc and spark devices.

Subclass 485: Phosphor on envelope wall
Subclass 486: Including particular phosphor
Subclass 503: With particular phosphor or electrode material

Class 252: Compositions

(A) Compositions of matter, having or not having structure, physical form or heterogeneous arrangement of components and for which there is no provision elsewhere. (B) Packages of such compositions, or other articles which include such compositions for which there is no provision elsewhere. (C) Processes of making, or peculiar to making, such compositions and for which there is no provision elsewhere. (D) Apparatus for use in or peculiar to such processes and for which there is no provision elsewhere.

Subclass 301.4R: INORGANIC LUMINESCENT COMPOSITIONS
Subclass 301.4F: Group IV element containing
Subclass 301.4H: Compositions containing halogen; e.g., halides and oxyhalides

Class 257: Active Solid-State Devices (E.G., Transistors, Solid-State Diodes)

This class provides for active solid-state electronic devices, that is, electronic devices or components that are made up primarily of solid materials, usually semiconductors, which operate by the movement of charge carriers - electrons or holes - which undergo energy level changes within the material and can modify an input voltage to achieve rectification, amplification, or switching action, and are not classified elsewhere.

Subclass 13: Incoherent light emitter
Subclass 86: Active layer of indirect band gap semiconductor
Subclass 94: With heterojunction
Subclass 98: With reflector, opaque mask, or optical element (e.g., lens, optical fiber, index of refraction matching layer, luminescent material layer, filter) integral with device or device enclosure or package
Subclass 431: Light
Subclass 678: HOUSING OR PACKAGE
Subclass E33.027: With heterojunction (EPO)
Subclass E31.019: Including, apart from doping material or other impurity, only Group III-V compound (EPO)

Class 136: Batteries: Thermoelectric And Photoelectric

The generic class for primary, secondary, and thermal batteries. It includes the structure of the generator or battery itself, the elements thereof, the methods of preparation, operation, and details, and accessories not provided for in other classes.

Subclass 257: Luminescent layer or optical filter
Subclass 261: Silicon or germanium containing
