I'm not sure how much input ADR had into the design... I'd suspect they were just the first people to import them into the UK and are now trying to protect their business.

Hmmm....
Looking at their website, it does (on first reading) give the impression that they designed them, eg referencing the first design draft.
But re-reading the page, it is quite carefully worded: "We wanted to market a bar..." [my emphasis] etc.
Also, the blog post I linked to only refers to warranty issues and not intellectual property rights: which you would expect the original designer to do. Although they do stress that the bars they are selling are unique.
So who did design them? I may be wrong, but I didn't know Hong-Fu produced original components of this complexity.

If I understand the situation correctly, ADR designed and developed the bars, that Hong-Fu rattled off a copy and PDQ are Hong-Fu with a mark-up.
