IP Rights in Unfair Competition - MCQ Controversy

Kya main galat hoon ya mere friend galat?

Question: Aamir Khan promotes a product of Pepsi in his movie, which doesn't explicitly advertise the product. Aamir Khan has given permission for the promotion. Is this a trademark infringement by Pepsi?

Mere friend ka khaandani: "Nahin, Pepsi has taken Aamir's permission, so no infringement. Woh permission ek sort of licence hai."

Mujhse lagta hai: "Lekin yeh fair use ka case hai. Pepsi aam sirf publicity le rahi hai, trademark infringement nahi. Mene R. v. Westinghouse case padhaya hai, woh bhi fair use ke sath related tha."

Kya aap logon ke paas samajh hai iska tareeka?
