I think if it "Fits" a Jeep you don't need license. If it "Says" Jeep anywhere on it, or you use Jeep in the advertising for the product, as well as Wrangler, CJ series, etc. you need either permission from Chrysler or put the standard "Jeep Disclaimer" in the advertising ("Jeep is a registered trademark or the Daimler Chrysler corporation").

That brings up an interesting point...how come we dont see that disclaimer when the words "Bronco" or Chevrolet" are used?

 

well thats kinda like when I make and advertise my half doors. I use the line: "for your Jeep vehicle" I think this would be ok, but not real sure.

 

As long as you do not infringe on DC's patents you're OK.

The problem is that do you know if your do-hickey that you make is possibley covered by one of thier (or anohter's) patents? Heck, often even DC dosen't even know what their own patents cover.... See the Ted Vanzant Story. And yes, if you use a copyrited word then you'd best give credit to the owner in an ad... It helps to cut down on lawsuits.

Now's a good time to hire a patent attorney, not later as lawsuits get real messy and expensive, real quick.
