First off: Your school's library is your friend, especially since you go to a large school. Use the online card catalogs and databases that are freely available to students like you. I can assure you that there are an absolute ton of resources lurking underneath your nose... go ahead and try it!
At the same time, there was one interesting case in intellectual property rights in fragrances. It was a French case, and I think that it was named Thierry Mugler Parfums vs. Molinard. It was over Molinard's Nirmala perfume, where Mugler claimed that Nirmala was an identical carbon-copy of Thierry Mugler's Angel. Thierry Mugler won the case, and Molinard had to reformulate Nirmala. If you have access to LexisNexis via your university's library (many schools do), you might try to look it up.
You might also want to take a look at this thread right here on Basenotes. It also relates to Angel, and how one group wants to ban the perfume in the United States due to the use of a certain ingredient.
Hope this helps!
