Drafting the Patent

This is where the expertise of a patent attorney, especially one with experience in pharmaceuticals, becomes invaluable. The way the patent is drafted can influence its strength, scope, and validity.

Filing Process & Timelines

Different jurisdictions have their timelines and processes for patent filing. Startups must be aware of the specific requirements, fees, and timelines of the territories they’re targeting.

Global Patent Strategies: Going Beyond Borders

Given the global nature of the pharmaceutical market, having a patent strategy that’s global is essential.

The Patent Cooperation Treaty (PCT)

For startups aiming for a global presence, the PCT provides a streamlined process for patent applications in member countries.

Advantages of PCT Filing

Using the PCT route, startups can delay the decision (and associated costs) of entering specific countries until 30 months from their priority date. It offers more time for market analysis and strategy refinement.

Navigating PCT Procedures

While PCT simplifies the global patenting process, startups must be wary of specific requirements like mandatory international searches and preliminary examinations.

Tailoring Strategies per Jurisdiction

Different territories can have varied patent regulations, especially for pharmaceuticals.

Understanding Regional Variabilities

For instance, patent laws in the European Union might differ significantly from those in the US or Asia. Being aware of these differences can influence filing strategies.

Regulatory Hurdles & Market Entry

In some territories, even after patent approval, regulatory hurdles can impact a drug’s market entry. Startups should factor these into their global patent strategy.

Patent Enforcement and Defense: Protecting Your Respiratory Drug Innovations

In the competitive landscape of respiratory and asthma drugs, having a patent isn’t just enough; startups need to be ready to enforce or defend their intellectual property (IP) rights.

Enforcing Your Patent Rights

Patent infringement can be a considerable setback for startups. Here’s how to navigate it.

Monitoring and Surveillance

Regularly monitor the market for potential infringements. Employing patent watching services can provide timely alerts when a competing patent application might infringe on yours.

Cease and Desist Letters

The first step, often before taking legal action, involves sending a cease and desist letter to the infringing party. This can be an effective deterrent, especially if followed up with clear legal intentions.


If peaceful negotiations fail, litigation might become inevitable. Startups should be prepared for the costs and the potential rewards of enforcing their patent rights through courts.

Defending Against Patent Challenges

With success comes scrutiny. Competitors may challenge your patent’s validity.

Post-Grant Review Proceedings

In jurisdictions like the US, competitors can challenge your patent’s validity after its grant. Familiarizing yourself with these proceedings and being prepared with evidence to counteract such challenges is essential.

Collaborative Dispute Resolution

Sometimes, disputes can be resolved amicably through mediation or arbitration, which can be quicker and less costly than litigation.

Expiry, Licensing, and Beyond: Maximizing Patent Value

Your patent strategy should also consider the lifecycle of your drug and its patent term.

Navigating Patent Expiry

As patents approach expiry, startups need to maximize their product’s value.

Supplementary Protection Certificates (SPCs)

In certain jurisdictions, SPCs can extend patent protection for a maximum of five years, compensating for the time taken in regulatory approvals.

Strategy Shift to Generics

Once the patent expires, startups can consider entering the generic market or collaborating with generic manufacturers to keep a share of the market.

Licensing Opportunities

Licensing can be an excellent way for startups to monetize their patents or expand into new markets.


If startups lack the infrastructure for large-scale production or global distribution, they can license their patent rights to bigger players in return for royalties.


Startups can also acquire licenses for complementary technologies or drugs, enhancing their product portfolio.

Navigating the Complexities: Advanced Respiratory Drug Patenting Approaches

In the competitive realm of respiratory and asthma drug patenting, it’s crucial for startups to be not just aware, but deeply informed. This requires going beyond the basics and understanding the intricate strategies that can pave the way for sustainable success.

Strengthening Your Patent Portfolio: A Multifaceted Approach

While a single strong patent can be a significant asset, the real strength lies in a diversified portfolio.

The Power of Patent Families

Having a ‘patent family’ is essentially having a suite of patents, related by subject matter, spread across multiple jurisdictions. This means you’re not just protected in one region, but many, ensuring global market potential is safeguarded.

Protective Layers Through Multiple Patents

Imagine having a safety net, and then another one below that, and another below that. Multiple patents on various drug aspects mean even if one layer is penetrated (or one patent is challenged), others are in place to protect your interests.

Capitalizing on Continuation and Divisional Applications

This strategy lets you modify, refine, or expand your patent claims based on a previously filed application. Think of it as an iterative process where you fine-tune your patent’s scope in response to market or research shifts.

Regulatory Data Protection (RDP) – A Silent Guardian

Beyond patents, RDP offers a shield for the invaluable data you generate during drug development.

Synergy Between Patents and RDP

While your patent protects the tangible aspects of your drug, RDP is your safeguard against competitors using your clinical trial data for their benefit. It’s a two-pronged defense strategy.

Mastering the Clock with Strategic Timing

Market exclusivity isn’t just about having a patent; it’s about maximizing its lifespan. By adroitly timing patent filings and regulatory submissions, you can stretch your market monopoly period.

Evolving with Science: Adaptive IP Strategy

Stagnation is a startup’s worst enemy. In the dynamic field of respiratory drugs, adaptability is non-negotiable.
