It's not always obvious which dropcatch company grabbed the name. Dropcatch, however advertise with a lander when they win, however, there are alot of dropcatchers out there.
Since each entity is allowed only so many requests to icann, alot of dropcatchers create multiple registrars to have more influence on the drop. I'm not certain, but if memory serves correctly, DC and snapnames each have hundreds in their arsenal to muscle for dropping names.
