and your use of Twitter to find single points of reference for your arguments is what I was objecting to above.

I spent over a decade working (among other things) around the @25k patents in a63b24 (CPC classification scheme).

Have a browse around that, if you're actually interested in understanding the tech behind it all, but until then I'm afraid I've got better things to do with my time than argue the toss with you on this.
