RomanToy - Even if you don't come to DNF often you joined like 3.5 yrs ago.... so even a part-time 'mainer should know Viagra is a TM by Big Pharma giant Pfizer, and they won't think twice before going after you legally, whether the name is making you $ or not, so delete it at once (DO NOT WAIT UNTIL IT EXPIRES, IT'S TOO RISKY), and you should never have bought it to begin with....(or handregged it), sorry to have to tell ya, better luck next time
The irony is that many of us may own TM names we may not know of, but this is an easy one, like GM, Coca-Cola or Valium, and therefore Pfizer can accuse you of a blatant violation of that TM anytime. And if you sell it and the guy who buys it from you gets in trouble later, he may lead Pfizer back to you as the seller. If you truly ignored that this TM existed when you acquired it (maybe you felt viagra was a generic term for the medication and not the brand) then maybe you could claim that, but they will still demand you turn the domain over to them, or that your registrar delete it at once
Aspirin was a TM at first for example -by Bayer- and it may still be, however generic manufacturers and other drug makers are all allowed to use "aspirin" as an ingredient or part of the title of their product instead of ASA which is the real generic term for aspirin, but Bayer allows it, Pfizer does not with Viagra
