I'm glad web companies don't take patents seriously enough to file one for everything they do for one, and second they don't enforce them. If they did, there would be no more "Pinterest for this..or the Netflix for that" and so on.<p>I really do believe the web is better off without patents and letting companies copy each other, and I think the same would be true for software companies, too, and maybe many other industries as well. Copying leads to competition, leads to further improvements and new ideas through combing old ones. Besides, wholesale rip-offs will always be criticized by customers anyway if they go too far, who wants to take their business to a "clone" anyway, when they could go with the original.
