Summary
The post explores the possibility of patenting taste in the context of Indian patent law, prompted by a comparison between Burger King and McDonald’s burgers. It discusses the differences between trade secret protection and patents for food products, highlighting the challenges of patenting sensory attributes like taste. The legal requirements under the Patents Act, 1970, including novelty and non-obviousness, are explained with reference to food innovations. The author notes that while it is difficult, patenting food based on taste is not impossible, provided the invention is sufficiently novel and well-documented. Recent examples and geographical indications in India are cited to illustrate the evolving landscape of food-related intellectual property.
The question of whether taste — as a sensory attribute — can be the subject of patent protection has acquired practical significance as food manufacturers invest substantially in developing distinctive flavour profiles. Two principal forms of intellectual property protection are relevant to food products: trade secret protection and patent protection.
Trade Secret Protection for Recipes
Recipes have traditionally been protected as trade secrets. Coca-Cola’s Classic beverage formula is a well-known example: the company avoids public disclosure and reportedly maintains the recipe in a high-security vault. KFC similarly maintains its recipe in secrecy, transporting it in a locked briefcase in an armoured vehicle. These strategies rely on the assumption that a competitor cannot replicate the product without access to the recipe. However, as analytical techniques improve, this approach carries increasing risk. Scientific methods capable of identifying the components of a food product may allow a sufficiently close imitation to cause commercial damage.
Patents and the Challenges of Sensory Attributes
Patent protection offers a different type of right: the inventor obtains exclusive rights over the invention for a defined period. Unlike trade secrets, a patent cannot be circumvented merely by scientifically identifying the components of the protected product.
Many attributes of food products have been successfully patented — fried pizza crust, microwavable foods, and similar innovations. However, obtaining a patent for a product characterised primarily by a sensory attribute such as taste is considerably more difficult. Courts have noted a lack of interaction between ingredients and have been concerned about the absence of an identifiable inventive contribution.
The Indian Statutory Framework
Section 2 of the Patents Act, 1970 defines an invention as a new product or process involving an inventive step and capable of industrial application. For a food product to be patentable, it must satisfy two criteria: it must be “new” (meeting the novelty requirement) and “non-obvious” — the inventor must demonstrate that the food radically varies from existing food products. The standard for evaluating non-obviousness is derived from the US Supreme Court’s decision in Graham v. John Deere. Section 10 of the Act requires that the patent specification include a description of the invention, its operation, use, and method of performance.
In practice, this means the applicant must measure and document the taste profile of the product and teach how to achieve and test it. The profile may be defined by reference to ingredients, processing techniques, or other characteristics such as caloric content, shelf life, texture, and appearance. Careful drafting and strong technical disclosure are essential. The more novel the concept, the stronger the resulting patent; however, the requirement for total disclosure creates the difficulty of explaining precisely how a recipe differs from any other person’s combination of similar ingredients.
Geographical Indications as an Alternative
India has granted Geographical Indication (GI) certification to products such as Basmati rice and the Hyderabadi Haleem, demonstrating that origin-based food protection is achievable under Indian law. GI protection does not require the same technical disclosure as a patent but protects the name and reputation of a product linked to a specific region.
