Blaine's example in trademark filing

The Arizona Diamondbacks debuted new uniforms last fall and plan to take to the field this spring adorned with a ‘db’ logo when sporting their alternate jerseys, while many including the Arizona Republic have written that it resembles a trademark of David Blaine.

Similarities between the Diamondback’s uniforms and the magician’s signature spade-shaped initials were noticed shortly after images of the logos were first released, most regularly on sports blogs and message boards but most notably in a column entitled ‘LET’S GET TERRITORIAL’ in the November 24th edition of the Arizona Republic. iTricks can now add that Blaine has a filed trademark with the United States Patent and Trademark Office dating back over a decade on the ‘db’ logo.

However, as of Thursday, January 18th, 2007 a search of the United States Patent and Trademark Office showed the Blaine filing does not cover apparel or clothing. It only lists the following in the Goods and Services section:

Fragrances for personal use; skin soaps; essential oils; cosmetics; body and hair lotions and oils; bath gel; hair care preparations; hair, skin and nail care preparations.

Here is the exact wording from the Blaine’s trademark filing describing the logo:

“The mark consists of stylized lower-case letters “D” and “B” appearing in a symmetrical arrangement.”

Arizona's new logo

A similar search for the Arizona Diamondbacks shows trademarks on the use of the name but nothing for a ‘db’ logo. The top picture with this post appears in the Blaine filing as an example while the bottom picture is what will be used by the Diamondbacks.

Officially, Blaine’s headquarters at db Productions had no comment on the subject but demonstrated an awareness of the issue.

iTricks will continue to monitor this situation but if you have any information at all please email

After the jump, we have posted a picture of Blaine’s ‘db’ filing…

From a search conducted January 18, 2007:

The Blaine Filing

    Trust me, this isn’t the first time somebody has come up with putting a db together. From a design standpoint its an obvious option.

    Move along, nothing to see here.

    There's no way I would mistake those two logos, so I don't see why there'd be any issues.
