Coin is infringing tens of thousands of US patents (you are, too) and quite a few companies are likely to soon have patents that attack Coin's core product in the next few years.<p>Big companies with plenty of cash don't usually die from patent wars anymore, though. Ever since the eBay [0] case (Thanks, eBay! Thanks, Supreme Court!) it's really hard to get an injunction against a company that can afford to spend a million dollars or so on lawyers. Now it's more common to wait and see if an idea prospers and then extort some reasonable amount of cash if it does.<p>Really small companies don't have that kind of luxury, of course.<p>[0] <a href="http://en.wikipedia.org/wiki/EBay_Inc._v._MercExchange,_L.L.C" rel="nofollow">http://en.wikipedia.org/wiki/EBay_Inc._v._MercExchange,_L.L....</a>.
