On January 1, 2013, the Cooperative Patent Classification (CPC) completely replaced ECLA, and all US published applications will now carry CPC classifications. The EPO’s Espacenet search system has already added a CPC search tool to its portal, and many subscription-based patent search systems have also integrated the CPC into their US and EP patent records and search options. The official CPC website currently offers an “ECLA to CPC to IPC” concordance table for users who need find a relevant CPC symbol that corresponds to an IPC or ECLA classification symbol. The USPTO website now offers an additional useful tool to help users locate the correct CPC symbol by searching for a corresponding US Patent Classification (USPC) symbol. With this tool, users can enter any USPC symbol and automatically generate a list of the closest corresponding CPC symbols.
It’s a little more than a year away, and it’s going to change patent information in a big way.
What is it?
It’s the Cooperative Patent Classification.
Last week the European Patent Office (EPO) and the United States Patent and Trademark Office (USPTO) launched a homepage for the Cooperative Patent Classification (CPC). This important milestone denotes progress on this giant and important project that we continue to be excited about.
Read along as we tell you the state of the CPC, why it’s important, and where we’re headed!
