"So, it is possible that post-victory sales could evidence bad faith. "
Well, yes, people will try anything. This sort of claim did not go over well with Judge Chin in the SDNY:

"The trial was canceled. Neither side requested reinstatement and the dismissal "with prejudice" therefore became final on or about September 14, 2000.

On September 25, 2000, Storey's counsel sent a letter to "Cello Limited" (the "September 25th Letter") stating that Storey had successfully concluded trademark litigation in which Storey's "ownership interest" in "cello.com" had been "challenged" by Cello. The September 25th Letter further stated that Storey was offering the domain name for sale. (Def. Mem. at Ex. 1).

The September 25th Letter was not an act of "cybersquatting" in any event. The fact is that Storey did prevail in the First Action. Cello filed suit, asserting claims to the domain name. The claims were dismissed "with prejudice." Hence, Cello failed to achieve the relief it had sought and Storey retained his registration of the domain name.
Cello cites several cases where judgments entered "with prejudice" were held not to have preclusive effect on later claims. None of the cases, however, remotely resembles this case. Here, the allegedly "new" act of "cybersquatting" occurred less than a month after the case was dismissed and was not a new transaction at all. Rather, the September 25th Letter was simply a reassertion by Storey of his rights to the domain name that had been confirmed by the dismissal of the First Action "with prejudice."
