Patenting Fragrances: Is It Possible?

The protection of fragrances through intellectual property law is a complex issue. While fragrances are generally considered formulas created from combined elements, the question of whether they can be patented or trademarked is not straightforward. In the United States, for example, scents can be trademarked as long as they are not functional, meaning they serve a purpose beyond simply smelling good. This excludes perfumes or colognes, as their function is considered to be the scent itself. However, in certain cases, companies have successfully trademarked scents that are integral to their brand identity, such as Hasbro's Play-Doh and Verizon's flowery musk scent in its flagship stores. While it is possible to patent the exact formula of a fragrance, it is rare for companies to do so as it requires disclosing all ingredients, which may be exploited by competitors. Instead, most perfumes are trademarked, protecting their name, image, bottle, label, and description.

Fragrances are a formula created from combined elements

The essential oils used in perfumes are derived from botanical sources like flowers, fruits, leaves, woods, roots, and resins. They are the foundation of many iconic scents, such as dreamy, musky red rose and rich, haunting jasmine.

Aroma compounds are also known as fragrance oils and are distributed according to an olfactory pyramid. They are divided into top notes, middle notes, and base notes, which unfold over time. Top notes are the scents that are perceived immediately upon application, while base notes bring depth and solidity to a perfume and are usually not perceived until 30 minutes after application.

Fixatives are vital to perfume formulation as they help to stabilize and prolong the evaporation process, ensuring the longevity of the scent. Some popular fixatives include resinous, vanilla-nuanced benzoin, and creamy, sweet, and woody sandalwood.

Solvents are usually alcoholic solutions, also known as extraits, extracts, or handkerchief fragrances. They contain about 10-25% perfume concentrates and are essential for lifting and disseminating fragrance notes.

The process of creating a perfume involves carefully blending and reformulating these elements until the precise formula is realized. It is a creative process of an intellectual nature, similar to the work of any other artist in the conception of their work.

The law is designed to make trademarking smells harder than trademarking words and images

However, scents that are not functional and serve a purpose beyond smelling good can be trademarked. For example, the scent of Play-Doh, described as a "sweet, slightly musky, vanilla fragrance, with slight overtones of cherry, combined with the smell of a salted, wheat-based dough," has been federally trademarked by Hasbro. In this case, the scent is not functional but rather a component of the product's trade dress, designed to be experienced in conjunction with Hasbro's "Play-Doh" word and design marks. Similarly, Verizon has a federal trademark for a "flowery musk" scent pumped into its flagship stores, which serves as an indicator that consumers are in a Verizon store.

To obtain a trademark for a scent, several criteria must be met. Firstly, the smell must be identifiable by consumers as part of the brand's product or service, differentiating it from other brands with similar offerings. Additionally, the scent must not be functional by definition, meaning it should not serve an important purpose within the product beyond helping consumers identify the brand. This criterion disqualifies perfumes or scented candles from trademark protection, as the fragrance they emit is the primary function of these products.

While it is challenging to trademark a scent, it is not impossible. By understanding the underlying purpose of trademark law and the specific criteria for scent trademarks, companies can strategically protect their brands and products through this legal mechanism.

Scents can be trademarked as long as they're not functional

Scents can be trademarked, but there are some important considerations to keep in mind. Firstly, while there is no rule that smells cannot serve as trademarks, the law makes trademarking smells more difficult than trademarking words and images. This is because trademark law is designed to protect indicators of source, and scents can indeed indicate the source or origin of a product. For example, the scent of Play-Doh is trademarked to Hasbro, and is described as a "sweet, slightly musky, vanilla fragrance, with slight overtones of cherry, combined with the smell of a salted, wheat-based dough".

However, there is a significant hurdle to trademarking a scent, and that is the functionality doctrine. Trademark law is not designed to protect items or products that have a practical use—that is the role of patent law. If a mark has a practical use, or is "functional", it is ineligible for trademark protection. This is to prevent a patent owner from seeking trademark protection when their patent expires, thereby extending their monopoly indefinitely.

Therefore, scents can be trademarked as long as they are not functional. A perfume or cologne, for example, is designed to make the wearer smell good, and this is its function. The law views scents for their own sake as being "functional", and will not allow them to be protected under federal trademark law. However, a scent can be trademarked if it is not being used for its own sake, but rather as part of a product's trade dress, designed to be experienced in conjunction with other marks.

In addition to not being functional, a scent must also be proven to be identifiable by consumers as part of a brand's product or service, and to differentiate that brand from others with similar products. For example, the smell of Play-Doh is easily recognisable and unique to the brand, and is not a necessary function of the product. Therefore, it was able to be trademarked.

A perfume's composition (list of ingredients) is patentable

While it is possible to patent a fragrance, it is a complex process. Fragrances are patentable because they are a man-made composition of matter. However, to obtain a patent, the fragrance must meet the requirements for patentability. This includes being utile, novel, non-obvious, and meeting enablement requirements. Enablement requires a written description of the item being patented, including the manner and process of making it.

The process of obtaining a patent is challenging, often requiring specialized expertise. Additionally, proving infringement of a fragrance patent can be difficult. Due to these complexities, many businesses choose alternative methods for protecting their fragrances, such as trademarks or trade secrets.

Trademark registration helps protect company names and logos associated with a fragrance. It prevents others from using similar names or logos that could confuse customers. To obtain a trademark, an application must be submitted to the trademark office, including branding materials, relevant images, and a detailed description of the fragrance. It may also be necessary to demonstrate that consumers recognize the fragrance as part of the brand, known as secondary meaning.

Another option for protecting a fragrance is by establishing a trade secret. Trade secrets are valuable pieces of information that a company keeps confidential to prevent others from copying them. To qualify as a trade secret, the manufacturing process and formula must be kept confidential or shared only with authorized individuals within the company. Additionally, steps must be taken to demonstrate confidentiality, such as limiting access to the formula, implementing non-disclosure agreements, and labelling related documents as "trade secret" or "confidential."

Although it is possible to patent a perfume composition or list of ingredients, the complexity of the process and the challenges in proving infringement lead many businesses to explore alternative protection methods such as trademarks and trade secrets.

The bottle, house, and brand can be protected by a trademark

The bottle, house, and brand of a fragrance can be protected by a trademark. This is a common way to protect fragrances and is often used in conjunction with registering the fragrance name as a word, figurative, or mixed trademark.

Registering a three-dimensional trademark for the bottle or packaging of a fragrance is possible, but it is not an easy option. The bottle or packaging must have a certain and important level of distinctiveness for it to be protected as a trademark. This distinctiveness is what allows consumers to identify products without needing to read the name of the trademark. For example, the bottles of Davidoff Cool Water and Carolina Herrera's "Bad Boy" have been protected as three-dimensional trademarks.

If a company is unable to register its perfume bottle as a 3D trademark, an alternative is to register the industrial design. This protects the aesthetic appearance of the product, including its shape, lines, colours, and other two-dimensional features. Examples of fragrances that have been protected in this way include Lancôme's 'Magnifique' and 'Idôle'.
