Keep in mind, this is just for the rocker/camber design, not all rocker designs. NS was at least a year out before other companies started getting on this bandwagon. Yet C2 won a product innovation award after the fact NS had been producing RC for a year. Though I am intrigued by Phillip's (Mike's) statement about Banana's having slight camber on the tips of their boards originally. I didn't get on a banana in their first generation so maybe they did. Lib had certainly abandoned it before then.
Also, it is not the easiest thing to challenge a patent once it's granted. NS was able to prove they came up with something original. Just like Mervin did with Magne. Magne has been a very enforceable patent for Mervin and I suspect the RC patent will be for Neversummer if they choose to go that route. Mervin was also trying to snag the patent on this tech, so it does give NS a good degree of protection.
How much resistance you'll see on this is going to be interesting. Mervin has big bucks and big lawyers on their side, but even they don't want a big fight over it. If it gets to court, nothing is a sure thing. My guess is they would settle for a reasonable fee and only take it all they way to a court room show down if NS pressed it. I also think there is reasonable grounds to believe that NS is going to do not much in regards to their patent.
This of course is all hypothetical. It's not my business. If it was me, I'd try to get some ducats out of it, just like Mervin and Burton have for their proprietary designs. Nothing wrong with the small guy reaping some benefit. If it's a reasonable fee, the industry will probably play along.
