I have to agree with MMario, and I'm rather surprised that the google "legal eagle" didn't insist on the ® or TM notation rather than the © thing.

Copyright generally applies to "whole ideas," and it's rather difficult to defend copyright of a "name" by itself, whereas this does appear to be a perfectly sound example of something that could be a "trademark." The protection afforded trademarks is actually, in some respects, much stronger than for "mere" copyright.
