DEFINITION

Classification: 570/101

HALOGEN CONTAINING:

(under subclass 1) Compound under Class 532, ... which contain an atom of halogen.

(1) Note. Due to hierarchical position of this subclass, compounds hereunder contain only carbon and halogen, or carbon hydrogen and halogen.

(2) Note. The patents found in this particular subclass relate primarily to processes of preparing saturated halogen containing compounds not specifically provided for below.
