Yes, but I just realized I was mistaken. The data I was talking about was the International Patent Classification. CPC was XML, IPC is HTML, and the former/now-deprecated US patent classification system was plain text. I have to deal with all three on a regular basis and have built importers for all three, and I forget which one is which.
IPC can be downloaded from the link below. I needed the Valid Symbol List. Looks like they fixed the encoded JSON that was there when they first put out the new format.
