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:
- 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?
- 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!
