USPC-to-CPC Concordance Tool Now Available on the USPTO Website!

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.

After the jump, Landon IP’s librarian Kristin Whitman provides a brief guide on how to use the “Statistical Mapping from USPC to CPC” concordance tool! Continue reading


How Major Patent Search Systems will Implement the CPC

The full roll out of the Cooperative Patent Classification (CPC) is less than a month away, and the classification search options for US and EP patent publications will soon change drastically for prior art searchers.  After January 1, 2013, the CPC will completely replace ECLA, and all US published applications will carry CPC classifications.  The EPO and USPTO released a “CPC launch package” back in October which contained the complete CPC scheme, any finalized CPC definitions, and an ECLA-to-CPC-to-IPC concordance. The USPTO and EPO have been thoroughly preparing for the transition to the CPC, but how are the distributors of major patent search systems preparing for the implementation of the CPC?  From the Major Recent Updates sections of the Intellogist Reports, I’ve compiled a quick guide on how Espacenet,, TotalPatent, Thomson Innovation, PatBase, and Dialog will make the CPC searchable within each of their systems.

Patent Search Updates from the EPO: New Features on Espacenet and the Full Scheme of the CPC

[tweetmeme source=”Intellogist” only_single=false] Where do you get your EPO news? There are plenty of choices to pick from: you can subscribe to an RSS feed for news or website updates, receive a bimonthly e-mail newsletter, or simply check the EPO website directly for news on important patent search and classification products created by the EPO, such as the free online patent search system Espacenet and the upcoming Cooperative Patent Classification system (CPC).  The EPO  recently announced updates to both of these products, so I’ll give you a brief run-down of the newest features on Espacenet and exciting news about the release of the CPC scheme and some definitions prior to the full January 1, 2013 rollout. Prior art searchers use Espacenet on a regular basis as a free source of global patent data, and the CPC will soon replace ECLA and the USPC as the main global patent classification system.

Stay up-to-date on the latest EPO news about these crucial patent search and classification products, and continue reading for a summary of recent Espacenet updates and a sneak peak at the CPC!
