Right. The pressure of a patent that is due to expire is itself a motivation to make a patentable improvement. And so the cycle repeats. But at the same time you reboot that product you're going to look at your competitors' innovations, especially the ones that are now out of patent protection, and consider reimplementing the features you had to work around with your more convoluted, non-infringing methods, using the original patented method. Because if it stood the test of time it is a good design. It's in the nature of things. I am sure Behringer is a bit on the slimy side, but implementing expired patents is what literally everyone does.
