  • I would suggest the preferred embodiments and all the others the are meaningful - this way you create prior art that will also allow you to do developments in case you are not protect with a claim, but you will not be limited by someone filing a different embodiment.

You must describe the preferred embodiment, but you do not need to state which of several embodiments is the preferred one.
