Ah, trademarks can definitely play a big role in branding and protecting your intellectual property. But did you know that some companies have taken it even further with unusual trademarks? For example, the scent of Play-Doh is actually a trademarked scent, along with other things such as sounds (like the sound of Netflix's loading chime), and even tastes (such as Coca-Cola's signature taste). I wonder what will be next to join the list!
