In this episode I answer an unusual but very real intellectual-property question: Can you patent a smell? I explain why a scent itself generally cannot be patented, but the chemical composition that creates it, the process used to manufacture it, or a device that releases it may be patentable. I also discuss when keeping a fragrance formula as a trade secret may make more sense than disclosing it in a patent, and how, in rare cases, a distinctive scent can even function as a trademark. The episode explores how patents, trade secrets, and trademarks can work together to protect different aspects of a scent-based product, and why inventors should think carefully before disclosing their formulas or inventions to the public.
