The fraudulent use of copyrighted trademarks usually doesn't require a lengthy lawsuit to shut down the counterfeiters. Usually, corporate counsels can get a "cease and desist" order very quickly.Proving fraud on a criminal level could be very difficult, but a civil suit only relies on the "preponderance of the evidence" for a successful win. Perhaps Colt Archive Services could try to pursue someone civilly?
That said, the person(s) doing this could be fairly "judgement proof," but if Colt Archive Services did pursue someone civilly -- assuming they can locate the likely party doing this -- it would send a strong message that could be effective in helping to stop this sort of activity. And sometimes starting a civil suit will result in enough evidence coming forward for a criminal fraud prosecution.
Not only is the person buying the gun with the fake letter being ripped off, Colt Archive Services' good reputation is being damaged by this sort of activity. (With the counterfeiting of boxes for models no longer being made, it might be difficult for Colt to argue its business reputation has been damaged, but with a counterfeit Letter, Colt Archive Services is clearly being harmed.)
Hopefully, Colt Archive Services will be having a lawyer evaluate its possible options and perhaps join in a civil suit an affected gun purchaser might bring against whomever sold him the gun when it is determined a counterfeit Letter is involved.
I worked at Ford Motor Company for over 38 years, and we had (and still do) our share of counterfeit parts, clothing, etc. Our counsel usually went to the appropriate U.S. Attorney's office, filed an expedited complaint, and a judge would usually issue an immediate cease and desist order immediately. The U.S. Marshal Service would conduct a raid and confiscate everything in sight. There was also a great amount of cooperation between Ford, GM, and Chrysler.
I would guess that Colt would be able to file an action in the appropriate Tennessee Federal Court and get an injunction against "Blovit" or "Vikrant" and put an end to it.
I guess the hardest part I have in understanding the problem, is that the Colt Combat Commander and LWT Commander names are jealously guarded. The other manufacturer's of such pistols always refer to them as "Commander like", etc.
In my mind the corporate name of Colt is a most valuable commodity, and I'd put Blovit out of business yesterday.
