U.S. Patent Classes & Classifications Covered in this Patent Portfolio: Class 239: Fluid Sprinkling, Spraying, And Diffusing The general class for claims pertaining to the spraying, sprinkling, or scattering of fluids or fluent solids either in the form of slurries or as dry material, over an extended area on a surface, including - weather control or modification, diffusers, fountains, drinking tubes and straw, dry pulverulent material, terminal fluid handling elements and orifice shapes.Subclass 1: PROCESSES
Subclass 499: Chamber-like deflector
Subclass 524: Transverse planar or dished surface type
Class 454: Ventilation This is the parent class for apparatus and processes for supplying air to and removing it from enclosures, for distributing and circulating the air therein, or for preventing its contamination.Subclass 310: Concentric
Class 438: Semiconductor Device Manufacturing: Process This class provides for manufacturing a semiconductor containing a solid-state device for the following purposes: (a) conducting or modifying an electrical current, (b) storing electrical energy for subsequent discharge within a microelectronic integrated circuit, or (c) converting electromagnetic wave energy to electrical energy or electrical energy to electromagnetic energy. Also operations involving: (1) coating a substrate with a semiconductive material, or (2) coating a semiconductive substrate or substrate containing a semiconductive region. It also provides for operations involving etching a semiconductive substrate or etching a substrate containing a semiconductive region. The class provides for packaging or treatment of packaged semiconductor.Subclass 473: By implanting or irradiating
Subclass 795: RADIATION OR ENERGY TREATMENT MODIFYING PROPERTIES OF SEMICONDUCTOR REGION OF SUBSTRATE (E.G., THERMAL, CORPUSCULAR, ELECTROMAGNETIC, ETC.)
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 E21.226: Dry cleaning (EPO)
