Divgradcurl and FlyingRon are nowhere around and yet you and I are posting away, The Occulist. It must mean our holidays suck.
ZERO HEROES, if you have not visited the US Patent and Trademark Office website, that would be a good first step for you to take. Go to
United States Patent and Trademark Office for the answer to the majority of the questions you may have. Div (an IP attorney) may post later to elaborate.
Registering your trademark with the USPTO makes it easier for you to protect your band's name against infringers, and it also provides notice to others that the name is taken, but it is the use of the mark in commerce that confers rights in a mark. The site provided above will tell you what the requirements are for registration, how to file an application to register your mark, and the costs involved in registration. It will also advise you on the benefits of registration. Registering your mark is something you can do on your own, without an attorney, although having an attorney advise you is recommended.
You may also want to check to see if the other band has registered THEIR name.
You have the burden of establishing your rights to the name and enforcing your rights to the name. You may sue to prevent the other ZERO HEROES from using your name and, for this, as has been advised countless times already by the forum members, you would be wise to consult with an IP attorney in your area. Unless your mark is well known (recognized by the general consuming public as a designation for your band alone), you may have a difficult time preventing the other band's use of the name ZERO HEROES. A cease-and-desist letter will not work if the other ZERO HEROES know they have an equal or greater right to the name.
If you sue to prevent the other band's use of the name, a court will look at how long the name ZERO HEROES has been used by both groups, the extent to which they have been used, the geographic reach of the use, the extent of the sales under the use, the recognition of the name in connection with the bands, and whether either mark has been registered with the federal government.
The court will look at whether the other name is being used on a competing good or service, whether consumers are likely to be confused by the same or similar names, and whether the marks are being used in the same part of the country or distributed through the same channels.
If the court finds that you have not been damaged by the other use of the name, the court may allow the other band to continue its use of the name - although, perhaps, and depending on all of the facts, in a more limited way. Or, and again depending on all of the facts, you may be prevented from using the name, or limited in your ability to use it.
I recommend you visit the USPTO website, check back here for additional posts (hopefully from divgradcurl), and consult with an attorney in your area to review the facts of your situation and to see what, if any, steps you can take to prevent the other band from using the name you wish to claim as yours alone.
As a final note: becoming educated is a fine goal, ZH, but being snippy with the forum experts here is not the best way to accomplish that goal. Your comments on the other site about FreeAdvice are interesting, by the way.
Edit to add:
FlyingRon stated in Zero Heroes' other, now-closed, thread that the "Zero Heroes" trademark was cancelled. Joe (aka Don Draper among others)'s "mom" filed for registration with the USPTO in May of 2001, the first use of the "Zero Heroes" mark was in September of 2001, the registration date for the mark was November 2002. The mark's registration was cancelled on June 27, 2009, because it was not renewed in 2008 as required. Joe needs to file again, if he has not already done so, to have a valid federally-registered trademark.
There are actually more than just the one additional "Zero Hero" group (and variations thereof) in the U.S. The one Joe is apparently referring to in this thread is located in Minnesota. This group has been performing under the name "Zero's Heroes" for some time. Other groups using the same or a similar name are located in other states (Maryland and Connecticut, for two). At least one of the groups has registered their name with their state. Even if these groups do not have federal registration, they may still have legally protected rights to their names under state registrations and common law.
I would be interested in hearing what divgradcurl thinks the odds are of an injunction being issued against these other groups, considering the June 2009 cancellation of Joe's mark, the state registration of the name by another group, and/or the use of a similar mark by other groups recognized in their areas under this name.
