Actually, after my third reading, I don't think it does infringe on their patent. The last comment on the GP link (3958) states: "The STRAIGHT addressing is not a belt because it uses ordinal instruction addressing, while a belt uses ordinal drop. But the new Clockhands addressing is a belt, pure and simple." But after re-reading the article again, it sounds like it genuinely is an extension of the STRAIGHT system to just add 4 groups of "ordinal instruction addressed" registers rather. It still definitely doesn't fulfil the criteria for "ordinal drop" as described in the comment (by the same author) that I quoted above.
