Yea, but in this case the property is very special. I don't think anyone has a right to own a "name" for perpetuity, especially such a short one—that's just extending property rights to a nonsensical place.

Granted, I also have zero respect for people who think that trademarks, patents, and copyright are still working to promote rather than stifle the arts and sciences, so I can understand why my above sentiment might rankle.
