RE:RE:The patent they wish they hadThe patent protects them. If you look at the Dropbox folder that Domdesm posts from time to time, you can view the patent and how it's a barrier to entry. Competitors have no choice but to license the product due to the patent. Competitor's will either look to buy the proprietary technology from TNG or pay them to use it. Either way, I'm happy. The last line says it all:
"To our competition (when they eventually appear), this will always be the patent they wish they had."
