This is an interesting article by Omar El Akkad with The Globe and Mail on the naming choices used by Paramount Resources Ltd. in Canada. Paramount Resources Ltd. is creating a new subsidiary called Pixar Petroleoum Corp.
I was pleased to talk with Omar about the potential trademark issues here and this is a very good example of the potential for use of U.S. trademark dilution law in the context of a third party using a trademark in the context a seemingly unrelated use (movies vs. oil fields). Not taking sides here but I would not be surprised if the folks in Canada receive a letter from California.
