IFI Concordance of U.S. Classifications to IPC

© Copyright 2000 by IFI CLAIMS Patent Services



The IFI Concordance of Patent Classifications is arranged in two sections, U.S. Classification order and International Patent Classification (IPC) order.

For U.S. Classification Order - The number of patents shown for each class represents the total number of patents posted as an original reference for the current year. The first IPC listed is the best one-for-one reference to that U.S. Class as determined by our program. This IPC represents the largest single percentage of all patents originally referenced to that U.S. Class or it has the largest percentage of multiple IPC's having the same first three characters. For International Patent Classification Order - the same information is shown as for the U.S. Classification Section, only in IPC order. The number of patents shown is the total number of patents posted to the IPC for the current year.
