Hi, I'm getting customized leather seats in jeep wrangler. I would like to get black embroidery of the 4 symbols (signs) to both front seats...But was told by company they can't to that because it's a trademark This has been 30 years in the making, once I got the jeep I wanted. This is a tribute to my brother who passed away in 1988 at age 17 in a auto accident. He would've been 50 this year.. He was led zepplin biggest fan.. I so saddened by this.. Though life whenever I have bad days zepplin always comes on the radio and I know it him watching over me... How can I get permission to trademark signs?
