The new system takes components from each office’s existing systems—European Classification (ECLA) and United States Patent Classification (USPC), respectively—and migrates toward a common classification scheme for both offices. The Cooperative Patent Classification (CPC) effort is a joint partnership between the United States Patent and Trademark Office (USPTO) and the European Patent Office (EPO) where the Offices have agreed to harmonize their existing classification systems (European Classification (ECLA) and United States Patent Classification (USPC) respectively) and migrate towards a common classification scheme. Help. About CPC Central Power Consultant (H.K.) Patent classifications can be very helpful for effective patent searching and apart from the standard international patent classification (IPC), the more detailed cooperative patent classification (CPC) is a very powerful tool, which is why we included both the IPC and the CPC in our comparison. Compared to liquid chromatography (HPLC), CPC is simpler and also more cost-effective, as matrix effects and irreversible adsorptions on solid phases do not occur. and Mark Maloney, JD, MS 93,1 % erreicht. Google Patents is Google's own patent search tool. The CPC is the result of a partnership between the EPO and the USPTO in their joint effort to develop a common, internationally compatible classification system for technical documents, in particular patent publications, which will be used by both offices in the patent granting process The CPC Implementation Team contributed to this article.
