Kaiser Industries was dissolved in the late 1980's. This is important as in 1955, Kaiser Motors Corporation (Kaiser-Frazer Corporation got a name change at the 1953 Stockholders Meeting) became Kaiser Industries Corporation. It acquired the copyrights, trade names, etc of Kaiser-Frazer as various agreements with debt holders made between 1953 and 1955 stated that no intangible property would go to Willys Motors, only physical assets (parts, tooling, etc) as Willys bought the physical assets from Kaiser Motors.
So who owns what? Although Chrysler Corporation claimed that their lock, stock & barrel purchase of American Motors in 1985 gave them Kaiser-Frazer related copyrights, the company disavowed any connection with Kaiser-Frazer Corporation or Kaiser Motors Corporation in a brief filed with the court regarding the EPA's attempts to assess monetary damages for the clean-up of the Willow Creek Watershed. If someone claims rights currently, they also have to accept responsibility for damages on the EPA case.
I helped to do the legal research for Chrysler Corporation and found all this out.
Additionally, when Chrysler emerged from bankruptcy it is my understanding that this further distanced the operation from Kaiser-Frazer and Kaiser Motors. Chrysler still retained the valuable copyrights, trademarks, patents, etc, that may still be valid for things pertaining to Willys Motors, Kaiser-Jeep & Willys-Overland.
