I'm starting to look into the history of The Coca-Cola Company's trademark protection efforts. This six-minute video by Babson College professor Ross D. Petty doesn't mention Carioca, but describes the company's aggressive efforts to legally block competitive products and unauthorized trademark usage.

I am researching for information on Walter Ruby inventor of a corkscrew pencil, Design Patent D-109879. I own an example of the combination corkscrew. It has a printed recipe far a Carioca Cooler cocktail. May I ask you to share any information on Walter Ruby's patent and any business dealings he may have had with Knud Knudsen the inventor of a pocket corkscrew # 2-164,191. Thank you very much!
