Navigating Pharmaceutical Patents: An Overview of Types and Applications

The significance of pharmaceutical drugs in the healthcare sector cannot be overstated, as their continuous advancement has revolutionized the treatment of various diseases. To foster innovation in drug development, pharmaceutical companies rely on drug patents, which help them recover their investments in research, clinical trials, and regulatory approvals over time.

The journey to create new drugs that are both effective and safe involves extensive research and dedication from pharmaceutical companies. These companies develop brand-name drugs, safeguarding them with patents. Once these patents expire, other companies, subject to necessary approvals, can produce and market the same drug under a different brand name, commonly known as generic drugs. Generic drugs are typically more affordable, making essential medicines accessible to a broader population.

In this blog, we will explore pharmaceutical patents, their types, and the relevant legislation influencing patent strategies within the industry.

Types of Pharmaceutical Patents:

Pharmaceutical patents can be classified into four main types, each designed to protect different aspects of a unique invention with specific application requirements. Let’s take a closer look at these patent types and their applications.

1. Process Patents:

Process patents safeguard the specific manufacturing processes rather than the end product. Such patents are commonly utilized in developing countries like India and Argentina, allowing variations in processes to prevent the monopoly of multinational corporations and cater to the needs of less privileged populations. However, these patents may discourage investments due to reduced profit margins, often leading to mandatory licensing for public welfare.

2. Product Patents:

Product patents grant inventors exclusive rights to their creations, preventing others from manufacturing or selling the same item. Developed countries such as the United States, the United Kingdom, France, Germany, Canada, and those following the TRIPS agreement adopt product patent regimes. While these patents protect inventors, they can also create monopolies, posing challenges in less developed regions where access to basic needs is already limited.

3. Formulation Patents:

Formulation patents protect specific drug forms or compositions, including certain drug classes and general formulations used in various medicines. Examples include slow-release technologies and transdermal patches. Understanding the type of patent is crucial during a comprehensive patent search as it aids in narrowing down the search focus.

4. Product-by-Process Patents:

Product-by-process patents describe a product based on its manufacturing method. They are granted when a product cannot be distinguished from previous creations except by its method of production. However, what matters for patent approval is the product itself, not how it is made. If a product from a product-by-process claim is not novel or unique, it may not receive a patent, even if the previous version was made differently.
