Recently on Good Morning Amercia, Hilton's CEO Chris Nassetta appeared to talk about Hilton's 100th Anniversary.
It was discussed, amongst other things, how Hilton has had many 'firsts', including first hotel room TV, first room service, first piña colada etc. One of the things Nassetta claimed Hilton invented is the chocolate brownie - first baked by one of the chefs at Chicago's Palmer House Hilton.
Looking at the wikipedia page for the Chocolate Brownie, this seems to check out:
"Bertha Palmer, a prominent Chicago socialite whose husband owned the Palmer House Hotel. In 1893 Palmer asked a pastry chef for a dessert suitable for ladies attending the Chicago World's Columbian Exposition. She requested a cake-like confection smaller than a piece of cake that could be included in boxed lunches. The result was the Palmer House Brownie with walnuts and an apricot glaze."
However, a quick read of the Wikipedia page for the hotel, we find that this Hotel did not become part of the Hilton chain until 1945, 52 years after the brownie was invented.
"In December 1945, Conrad Hilton bought the Palmer House for $20 million and it was thereafter known as The Palmer House Hilton. In 2005, Hilton sold the property to Thor Equities, but it remains part of the Hilton chain."
My question is: Is it legal for a company to claim ownership of a product if they buy the place in which it was created?
