Lynn,
I am doing something incorrect for which I apologize. I have just done this answer twice. First I was instructed that I was either not logged in or that I was not granted access to the page, and then, having logged in again, was told that I posted the answer two times in 5 minutes. However, I do not see my answer? I am sorry for not being better at this!
I posted a reply last week, however, it appears that I did something wrong and it did not appear in the thread.
When Peter Thorp began making the MkVs, he wanted his cars to have the only successive serial numbers and the only cars allowed to have the GT40 name. He then applied for a trademark registration in the USA and the UK. The UK denied his request as "GT" was widely used, and "40" is a number which was deemed to be not able to be registered as a trademark. The USA, however, did grant Safir Engineering (Peter Thorp) a registration. Prior to that time, "GT40" had never been registered by anyone, including Ford. As we subsequently researched Ford's registered trademarks, we learned that Ford never registered their very well known marks "Mustang", "Fairlane", "Falcon", and "Galaxie 500" until the '70s and '80s as I recall. I might not be precise on the specific marks and the times, however, suffice it to say that Ford was not concerned with registering trademarks of vehicle models, and certainly not interested in registering the name of an outdated racecar.
The USA, and other nations as well, require that an entity show continuous use of a trademark; not doing so for a period of now two years (it used to be three) constitutes abandondment. After that time period anyone can make an application to register the trademark, show "intent to use", be subjected to "opposition", and then be granted a registration. Ford never registered the mark, and then abandonded its use. The mark was available for anyone to register; anyone, that is, with a legitimate "intent to use", i.e., product on which to use the mark.
At the time, 1985, Peter Thorp told John Wilment that he was registering the mark, and Wilment had a 30 day "opposition period" to file an opposition and argue against Safir being allowed to register the mark. Lee Holman had the same opportunity. Neither filed an opposition
Lee Holman later filed a "cancellation" against the mark claiming that the term "GT40" was generic. He claimed that "pick up " describes a type of vehicle, and "GT40" just describes a type of vehicle. He lost his case with prejudice, meaning that he cannot bring a case against the mark again; prejudice meaning "prejudged". The next time that he brings a case against the mark the case has been "prejudged" that he will lose.
Ford never registered the mark, Ford stopped using the mark (abandoned the mark), and Safir applied for and was granted a registration for the mark for use on a product, the MkV.
