How to get current IPC

Hi Community,

I am working on the ipcr.zip file. I want to keep consistency between IPCs of different versions, especially before and after 2006. I know that the IPC in the file is as of the publication date. I have two questions:

  1. I know that the IPC in the file is as of the publication date. So how can I generate the 2006-version IPC of those patents before 2006. For example, let's look at Patent No. 6,000,000 (USPTO page is here). Its IPC as the publication date is "G06F 017/30", while its 2006-version IPC is "G06F 11/14". But I can only find the IPC as the publication date in the ipcr.zip file. I wonder if there is any way to accomplish it?
  2. The second question is also about the version. I would like to ask whether the IPC version for those post-2006 patents is 2006-version if followed by "(20060101)", even the publication year is not 2006. Take Patent No. 9,000,000 (USPTO page is here) for example. Its publication year is 2015 and it only has one IPC, "B60S 1/48 (20060101)". Does it means the IPC version here is 2006?

 

Thank you so much!

Best,

Xugan

no bulk source

Hi Xugan,

pvteam can confirm but I think the ipcs are coming from the grant xml file so they reflect their at-issue ipcs, not what they are currently.  As far as I know there is no bulk source of them as there is for cpcs, so the api's database and bulk files do not have the current ipcs.

https://bulkdata.uspto.gov/ has bulk cpcs for utility patents only (not plant and reissued patents that receive them) and the uspc file mcfpat.zip has not been updated since 2018 (plant and design patents still receive them). I'm sure if more bulk classification files were available, the api team would be happy to use them!

Hi Russ, Thank you so much…

Hi Russ,

Thank you so much for your quick and helpful reply! I will take a closer look at cpcs as it has bulk source.

Thanks,

Xugan

Confirming IPC source

Hi Russ and Xugan, Russ is correct on the IPC and CPC classification information he provided. We have some additional background information on classifications here: https://patentsview.org/classification.
