The pharmaceutical industry is rife with competition, and in the bustling market of antihistamines and allergy medications, securing a patent can be the difference between market dominance and obscurity. If you’re a startup exec diving into this realm, having a robust patent strategy is vital. This article outlines effective strategies and considerations for patenting antihistamines and allergy medications.

Understanding the Basics of Antihistamines and Allergy Medications

Before you embark on the patenting journey, it’s essential to grasp the core concepts.

What are Antihistamines?

Mechanism of Action

Antihistamines work by blocking the effects of histamine, a chemical involved in many of the body’s immune responses. When released in large quantities, histamine causes the symptoms we associate with allergies, such as sneezing, itching, and swelling.


Antihistamines are often categorized based on their generation (first, second, third) or their structural class. Each generation or class has its own set of benefits and potential side effects.

If manufacturing and distribution aren’t your startup’s core strengths, consider licensing your patented drug to established pharmaceutical companies. This can provide substantial upfront revenues and ongoing royalties.

Expanding Patent Lifespan & Effective Lifecycle Management

In the cutthroat world of pharmaceuticals, each day of patent protection can equate to significant revenue. It’s not just about obtaining a patent; it’s about maximizing its lifespan and managing its entire lifecycle.

Techniques for Patent Term Extension

Regulatory Time Compensations

The journey from lab to pharmacy shelf can be long, primarily due to regulatory scrutiny. Many jurisdictions offer patent term extensions, compensating for the time lost during such regulatory reviews. Ensure you understand and take advantage of these provisions in your target markets.

Pediatric Study Extensions

In regions like the U.S., performing and submitting pediatric studies for your drug can offer an additional six months of patent protection. While there’s an associated cost, the market exclusivity can more than compensate.

Strategizing Around Secondary Patents

Diversifying Formulation Patents

While the original compound patent might have a limited lifespan, subsequent patents on new formulations, combinations, or methods of delivery can provide additional layers of protection. This creates a barrier for generic competitors even post the primary patent’s expiry.

Innovations in Production Processes

Any unique methods developed for synthesizing the drug, achieving higher purities, or ensuring batch-to-batch consistency can also be patented. This doesn’t just offer protection but can also position your startup as a leader in production quality.

Preparing for the Inevitable: Generic Competition

Generics are not just competitors; they’re a different ballgame altogether. Being proactive can ensure you’re not blindsided.

Smart Evergreening Tactics

Repurposing your drug for new allergic conditions or discovering auxiliary therapeutic benefits can give your product renewed market exclusivity.

Reinventing Delivery Mechanisms

Beyond merely a new formulation, consider entirely novel delivery methods. For example, if your drug is typically taken orally, a transdermal patch or a nebulized version could offer patients something new, creating a fresh patent opportunity.

Solidifying Brand Loyalty

Patient-Centric Initiatives

Loyalty can be cultivated. Consider loyalty programs, discounts for long-term prescriptions, or even simple educational seminars on allergy management to keep patients engaged with your brand.

Engaging the Medical Community

Regular sessions with healthcare professionals, offering samples, and presenting clinical trial results can ensure they prescribe your brand confidently. Their endorsement can significantly sway patient choices.

A Global Perspective on Patent Portfolios

With varying regulations and cultural nuances, global patenting is complex but necessary for major market players.

The Power of Priority and PCT Filings

The Paris Convention’s Priority Principle

By filing initially in a member state, you can then leverage that filing date in other member states. It’s like freezing time, ensuring you don’t lose out on any patent protection days.

Streamlining with the Patent Cooperation Treaty (PCT)

The PCT doesn’t give a worldwide patent, but it simplifies the process, bundling numerous applications into one. It offers you a cushion, giving you up to 30/31 months to decide your target countries for patent protection.

Recognizing and Adapting to Regional Dynamics

Grappling with Patent Standards

Different countries have unique benchmarks for novelty and non-obviousness. Your application might need tweaking to fit these criteria. Engage local patent experts to guide your applications appropriately.

Staying Culturally Sensitive

Understand regional sensibilities. A formulation acceptable in one country might be shunned in another due to cultural or religious dietary restrictions. Ensure your formulations are universally acceptable or create region-specific variants.

Staying Vigilant: Monitoring and Enforcement

Patents are only as strong as your defense mechanisms.

Maintaining a Proactive Patent Watch

Competitor Intelligence

Keep tabs on competitors’ patent activities. It can provide hints about their R&D direction and alert you to any potential infringement.

Alert Systems for Generic Filings

Generics often challenge patent validity to enter the market earlier. Setting up alert systems for such filings can enable faster responses, protecting your market share.

Swift and Decisive Enforcement Actions

The Art of the Cease and Desist

Often, a well-crafted cease and desist letter, highlighting your patents and willingness to defend them, can deter potential infringers without resorting to courts.
