This sounds more like an advert than a news article - where is this mass of gravel and road riders that have been calling for four piston brakes?

RE prior art etc, the big difference with the hope brakes is the 2-part construction (hope are a single block) so a patent could be for a flat mount, 2-part, 4 piston brake?

can't see the patent app being successful - Hope Tech could easily cite prior art and get it blocked.

We recommend spending a bit of time solely to bed in the brakes ahead of any proper rides by finding a hill (or a flat if you, handy for those intervals) and rolling down while gradually applying pressure on both brakes until the bike comes to a stop. Repeat this a few times to ensure proper bedding in. 

Neglecting to do this could mean that your brakes never bed in properly, thus introducing squeal and less-than-ideal braking power. That aside, it's safe to expect noisier brakes in the wet and cold with, or without four-piston calipers.

premature comment posting. how do they expect to patent it when there is prior art and product?
