names are trademarked: Albus Dumbledore, Minerva McGonagall, Severus 
Snape, Rubeus Hagrid, Gildroy Lockhart, Voldemort. Why these names were 
chosen and not Hooch, Pince, etc., is a puzzle! There aren't cards for 
HRH, but I assume they're also trademarked.

Tonks:
Hooch and Pince are not trademarked by WB, because someone else already 
had them. Ron Weasley, Hermione, Hermione Granger and Harry Potter are, 
of course. You can find trademarks here:
