All good information. However, the Shelby GT, Shelby GT350 and Shelby GT500/GT500KR usage have been under CSL (Carroll Shelby Licensing) for decades.
When Shelby lost control in mid 67 Ford took all the assets and trademarks. When Ford brought out the Fox body with GT350 side stripes Shelby sued. He got reminded that he no longer owned the trademarks. Ford allowed/licensed him to use the Cobra name on 2 seat sports cars and retained its use for everything else. When the whole Cobra kit car lawsuits started Ford defended the Cobra name and won. Shelby defended the shape and lost. The GT350s and GT500s that left Las Vegas entered there as FORD GT350s and FORD GT500s. If you click on the GT500 link on the Shelby American site it takes you to the Ford build and price page.

Don't forget the original 1962 Shelby American Inc ceased to exist in 1988 when Carroll and Patrick closed it down. Go to the Secretary of State sites in CA and NV you'll find lots of interesting paperwork on CS's companies.

CS vs Factory 5: Ford was in on original 2000 case as the trademark owner relating to use of the terms Cobra, 427 S/C, Shelby, Shelby Cobra, Daytona Coupe and Daytona Coupe Cobra. Factory 5 had never used any of these trademarks so Ford left the suit with an agreement Factory 5 not use them. CS stayed on with the trade/dress part (shape/look)
Carroll Shelby has failed in his second attempt this decade to halt Factory Five Racing from manufacturing and selling kit cars which resemble vintage 1960's Shelby automobiles. In a ruling issued yesterday by the United States District Court for the District of Massachusetts, the Court dismissed Carroll Shelby's 2009 suit against Factory Five wherein Shelby alleged that Factory Five's Type 65 Coupe infringed on the trade dress (design trademark) of Shelby's Daytona Coupe® automobile. Shelby filed a similar suit against Factory Five in 2000 alleging trade dress violations of "designs that relate to the vintage 1960's automobiles created, designed and made by Carroll Shelby" including but not limited to the COBRA 427 S/C®. After almost two years of litigation, Factory Five and Shelby settled the earlier suit pursuant to which the Court dismissed Shelby's trade dress claims relative to Factory Five's kit Roadster and Type 65 Coupe which are similar to Shelby's COBRA 427 S/C® and Daytona Coupe®, respectively.
Despite Shelby's dismissal of the trade dress claims in the 2000 law suit, in December, 2009, Shelby attempted a second bite of the apple by filing suit against Factory Five, this time on his home turf in the federal court in Los Angeles. However, the change in venue was short-lived. Over Shelby's arduous objection, Factory Five was successful in having the suit transferred to the District of Massachusetts, the site of the earlier litigation. Shortly thereafter, Factory Five filed its Motion to Dismiss based, in part, on the Court's judgment in the prior law suit.
