The USPTO also published on Sept. 2 Classification Order 1880 covering a new cross-reference art collection labeled G9B, Information Storage Based on Relative Movement Between Record Carrier and Transducer. The order provides little information on the origin of this class, other than to say that it was established in 1979 and is connected to something called an IdT scheme, which is a European classification system. Obviously, it resembles an IPC class and not a USPC class. There are no patents classified in G9B at this time. Perhaps it is a new e-subclass.
