How to Find CPC Codes for U.S. Patents

Title
How to Find CPC Codes for U.S. Patents
Abstract
This is one of a series of videos we have on patents. It’s all about Cooperative Patent Classifications, and where to find them.

This classification system groups similar things together, like the Library of Congress or Dewey call number system that libraries use for shelving books. We are talking about the CPC, cooperative patent classification, developed in 2013 between the US and European patent offices and that’s what’s used for new utility patents in the US.

In the older search interface for US patents you really had to have a CPC or the patent number to find things, and while this is no longer the case, it’s much better at using keywords now, there is still value in knowing about these codes and at times using them for your search.
