Could they be planning on suing all the small time startups that use the word "bitcoin" in their products? Perhaps they think they can extract some money from small companies by threatening them with lawsuits if they don't pay up.
I can't edit my other comment, so let me try again: the phrase "piece of work" is generally an indication of strong disapproval.
Since there is nothing apparent on the page that was linked to that seems objectionable upon casual examination, I am curious what f1gm3nt saw there to indicate that the guy is "a piece of work".
IANAL but I believe you can apply for a registered trademark on a name you've already been using in the marketplace for some time. Maybe someone knowledgeable can comment on the specifics?
Trademark application states the first use was on this date. Also note that the Specimen was also used to create the article about bitcoin http://www.pascazilaw.com/Articles.html
Another nice thing to note is that the letter is from Magellan Capital Advisors, LLC. Notice the signature at the bottom of that letter is signed by Celline M. Pascazi. I can only assume she is related to someone at the law firm, Pascazi Law Offices.
I really don't think this will get approved since it's very obvious that this is a trademark troll. be very interesting to see how this plays out.
