No of course they aren't but the output of any of the factory patches would still have a fingerprint that would match significantly at the outputs as well.
If the patch was edited to significantly change the digital fingerprint of the waveform from that created by the original factory patch ... then that would not be subject to copyright because it would really become an original work at that point. And it would require work.
Note though it must be edited to significantly change the digital fingerprint so it really is a distinctly different waveform.
Now whether manufacturers would ever be that interested in comparing digital fingerprints of waveforms is doubtful. But if they thought their market was being threatened their sounds being carbon copied they would have legal grounds to do it.
None of this should really affect how musicians use sounds and styles in their own music anyway.
Besides, sampling any other synth doesn't come close to the original in terms of playing dynamics because it is just a snap shot. None of the realtime filter settings and after touch controls are active on the sample. That would require much more programming, and then it probably would be better to not print the original programming or effects. Personally I don't think the original manufacturers would feel that threatened by the result.
Creating a good sample based patch with layers and velocity switching is not something that is easily accomplished. Better off just using off the shelf solutions ... they will probably sound better.
