Re: Patent... really!
@Efros, Martin Gregorie, and AC:
You give the impression you haven't even glanced at the patent application before commenting on it. You're not alone; this is currently very common behaviour amongst Reg commentards, but I have no idea why people upvote you for it.
The patent is NOT for 'any case made of carbon-fibre reinforced plastic'. Rather, it outlines a very specific design, and how it might be manufactured. The language is bit dense, but two materials are involved, and several processes. Carbon fibre reinforced plastic is not suitable for edges and corners- it can chip and fracture quite easily, so that place is taken by the 'spine' the patent refers to. The spine also acts as former during manufacture, and is then bonded or fused to the CFRP layers to form a whole that won't separate with thermal cycling.
@Efros- Just because people have used cardboard boxes in the past doesn't mean you can't innovate and make a cardboard box better suited to your purposes- and then patent it if it is non-obvious. Have you never heard of Tetrapak? Have you not seen those flat-packed cardboard wine boxes in supermarkets (the ones that unfold into six compartments and a handle)? What about the cardboard storage boxes that don't require tape to assemble, and the tops fold over to reinforce the handles? Not only did these shapes have to be considered, but also the process which makes them.
What is it that you have against the designers of cardboard boxes and manufacturing processes? Any reason you feel they shouldn't be rewarded for their efforts?
