Has anybody heard of this, using cork (or maybe more specifically, core cork) on a deck of a surfboard is patent protected? This video is 6 years old but this is the first time I've seen it or any mention of cork decked board's being patent protected. I did a search about patents and came up with that huge one by kawika, but I'm not trying to start a good patent/bad patent arguement. I'm more curious about those of you making these boards already. Any feedback?
