Too bad its useless, but it would be nice from registrars to give some kind of warning when a "TM name" is find in your domain before registering it. Some are obvious like in this case, but not all the time.
Trademark violation. Expect to be contacted by Pfizer's legal department if you attempt to use it...unless you're in China
