Maybe they did invent that scheme and everyone copied them, but if so, they're not enforcing it in the UK.
a) That's in the UK where Fluke doesn't have the same protections.
b) Those are newer, cheap, meters aping the design of Flukes, for that search to mean anything it should look back before Fluke's popularity or at least before they started using the current trademarked design.
c) Past just the first page the split gets much more even.
Your claim that they're "aping the design of Flukes" is unsupported. I haven't seen any evidence that Fluke invented that design or colour scheme, rather than it becoming a fairly common format for multimeters and then Fluke deciding to copyright the design.
A lot of older multimeters look like this: http://www.eevblog.com/forum/chat/show-your-multimeter!/540/ or something similar at least once handheld meters with multiple modes started to become an actual item. That whole thread is a decent cross section of multimeters, though it's skewed towards nice older meters as opposed to lower grade meters.
