Pretty sure this is not a valid trademark. The term/name Bitcoin was already established before the date of the trademark.
This. I'm also pretty sure a trademark only allows for protection against uses of it that would hurt business for the trademark holder, too.
Even if that's not true, the bitcoin community has been using the term for quite a while.
Registered owner is "Magellan Capital Advisors". Looks like a banking outfit. Any use of BTC would surly compete with the established banking system.
