Even if that were the case, it's still beyond the scope of the allegations that can be made in a DMCA takedown notice. If they were asserting any patent rights, that would have to be through a regular cease & desist letter. It is possible though unlikely that patents could come into play here, but they clearly haven't yet.

No, it's a copyright issue. Patents have nothing to do with it.
Unless any method or procedure (parsing of natural language configuration files or something) is patented.
