CPC Definition - Subclass G04D
This place covers:
Apparatus, devices, tools and machines for manufacturing, processing, assembling, lubricating and testing clocks or watches and units thereof.
The general aspects of machine tools or metal-working not specially adapted for G04D are covered by class B23. Grinding and polishing in general are covered by class B24. The general aspects of hand tools, portable power-driven tools, handles for hand implements or manipulators are covered by class B25 .
In horology only a low percentage of patent applications deal with machines and tools, however manufacturing methods have become very popular: these are normally classified in G04B (for example G04B 17/066: manufacture of the spiral spring) however the working process of the machine may suggest a manufacturing process, so please consider searching in the relevant G04D subgroup when dealing with a manufacturing method.
This place covers:
