Their patent claims were mostly against Curtis, because he used ailerons to control his turns, and they claimed he usurped their wing warping method. While they both accomplished the same thing, they are not identical and I think their claim was wrong and arbitrary(I believe they eventually lost the claim).
They spent so much time in patent fights that they lost out on aircraft sales and on chances to improve their aircraft.
The Wrights were stretching a lot weren’t they? Something can always be improved. Just a fact of life.
