My sister owns a small bakery that she has had for 25 years and recently another business used a variation of her name in a new same-industry business in the same state. She learned that if they had registered the name in either a state, or national trademark, they could legally demand that she discontinue using her own name! Upon further research she found out that in another state someone had registered the exact same name and could also issue a cease and desist letter to her but did not because they are both small local businesses and nobody really cared if another business had the same name three states away.
She had also received a letter from the Disney Company years ago to cease and desist decorating any image of a Disney character on a cake. She could not legally decorate your kid's cake with Mickey Mouse or be legally liable. She could buy the plastic characters and stick them on the cake but no reproductions were allowed. She still has that letter under the counter to show parents why they can't have Cinderella on their four-year olds cake.
Unfortunately, if you are foolish enough (no offense intended) to not protect your assets this is what can happen, fair or not.
What I find interesting is that the whole “Got (fill in the blank)?” is a variation/modification of the National Milk Advisory Board's successful campaign of “Got Milk?” of a few years ago, and if they chose to they could issue a cease and desist letter to anyone using that format (even Genos') even though the name is changed, because it is obviously similar in spirit to the original slogan. I can only assume they don't because there is no direct competition or confusion in slogans like Got Diesel? and Got Milk?, but they could do so and probably succeed legally. I'm sure they could have challenged the registration of “Got Diesel?” if they wished to do so. (Maybe you should write them a nice letter!)
A few years ago we had a similar situation locally when Huntington Beach, Ca registered as a national trademark the phrase “Surf City”. Now, Santa Cruz, Ca had been using that moniker for many years, as had Huntington Beach and other coastal cities in California, but HB took the trouble to register it nationally and issued a letter to Santa Cruz to stop selling T-shirts with that phrase on it. Can they do that? Yes they can and they did and it created bad blood that continues to this day. It is fair?, no it's chicken-**** and low-handed just like this diesel situation.
Why not foster an attitude of friendly competition rather than legal strong-arming. Dieselsite was smart to register the phrase but not so smart in how they enforced it with the TDR, as it also just makes bad blood and makes them look like horse's rear ends. The shirts were mostly sold for charitable causes so they look like a bunch of bullies in this.
The downside of registering nationally is that, if I undestand it correctly, you have the legal responsibility to challenge any and all that may use your trademark or you can lose the right to it. You are supposed to monitor the trademark and defend it in all cases, hence the Disney letter. In the end the lawyers win the most. Dieselsite sent the letter to retain their legal rights but perhaps in this situation they may allow you to continue in good faith in a limited manner such as the shirts. You can use anything with the owner's approval.
With that all said, I would suggest that the TDR, if they have not already done so, register nationally the phrases “TDR”, “Turbo Diesel Register”, and “We are the Number One Resource for Dodge/Cummins Turbo Diesel truck information”, as well as any logos just in case this inspires any others to ride the tails of this forum. Of course that all depends on whether anyone can register any phrase with “Cummins” in is as that is a worldwide trademark already.
When you choose a winner in this contest, register it first, and then announce the winner, in that order.
My simple suggestion is “Drive Diesel?”
Good luck and happy smoking!
