From the TTABlog:

Major League Baseball has opposed two applications filed by Mattingly Hitting Products, Inc. to register the logo shown below left for “baseball and softball equipment, namely, bats, gloves, mitts, bat cases, bat bags, and batting gloves” and “clothing, namely, shirts, pants, athletic uniforms, caps and hats.” MLB claims a likelihood of confusion with its “Silhouetted Batter Logo,” registered for the same goods. Major League Baseball Properties, Inc. v. Mattingly Hitting Products, Inc., Opposition No. 91177266.

The logo in question probably shouldn’t confuse anyone as to whether or not it’s the MLB logo, but then again, people are frighteningly stupid.  Here’s Mattingly’s logo:

Of course they’re similar – they both feature a left-handed hitter – but nobody should be confused here.  It’ll be interesting to see how the court rules.  But let me be the first to point out that all this could have been avoided if Mattingly insisted on a logo that featured a mustache.  Why the hell wouldn’t he just slap a mustache on the hitter?  It would without a doubt avoid any confusion, plus it would make a damn cool logo.  Like mustaches don’t rule?  It’s so damn obvious and easy.  No wonder Don Mattingly isn’t Hall of Fame material.
