Yes. There is a final date on which patent rights eventually do expire, but you will have to do your own research on the patent in question.
In the USA, unfortunately, no. Lunesta's patent doesn't expire for at least 4 years. In my educated opinion, the sedating tetra-cyclic antidepressant mirtazapine (brand name Remeron) is a far superior (and far cheaper) alternative to Lunesta. Get with a psychiatrist or sleep specialist and try it. You'll thank me later. PJF
Supposedly it expired decades ago...
