What is an International Patent?
An “International Patent” generally refers to patent protections pursued across multiple countries to secure exclusive rights over an invention worldwide.
While no single “global patent” exists, the Patent Cooperation Treaty (PCT) offers a streamlined process for filing patent applications in over 150 countries, enabling inventors and businesses to file one “international” application that can later be extended to individual member countries.
This process allows inventors to reserve international rights while deferring the cost and complexity of filing directly in each country.
For companies with inventions that have global market potential, pursuing international patent protection is essential to prevent unauthorized use in other countries and establish market exclusivity on a broader scale.
Why International Patents Matter for Business Leaders
Securing international patent protection enables companies to safeguard their innovations in multiple markets, protecting their intellectual property from foreign competitors and strengthening their global presence.
Market Exclusivity Across Borders: An international patent application (through the PCT process) allows businesses to reserve their rights in numerous countries, giving them the option to enter or license their technology globally without risk of immediate competition.
Strategic Market Access: International patents allow businesses to secure rights in high-priority markets, adapting patent protection to the regions where the invention has the most potential.
Investor Appeal: Investors view international patent filings as a sign of a strong IP strategy, particularly for innovations with broad, global appeal. It signals that the business is serious about protecting and maximizing its invention’s potential.
Key Insight: An international patent strategy provides businesses with the flexibility and control to secure market exclusivity on a global scale, offering protection in priority regions and reinforcing investor confidence.
Real-World Example: Pfizer’s International Patent Portfolio for Lipitor
Pfizer’s cholesterol-lowering drug Lipitor became one of the best-selling drugs worldwide, thanks in part to an extensive international patent portfolio.
By pursuing patent protection across key markets globally, Pfizer ensured exclusive rights to manufacture and sell Lipitor in regions where demand was high.
This global patent strategy allowed Pfizer to maximize revenue from Lipitor and prevent competitors from producing generic versions in high-value markets.
Takeaway for Business Leaders: For products with global demand, international patent protection can safeguard market share in multiple regions, ensuring exclusivity and maximizing revenue potential across borders.
Key Components of the International Patent Process
The PCT application process provides a pathway for pursuing international protection, allowing businesses to file in multiple countries from a single application.
Here’s how it generally works:
PCT Filing: A single PCT application is filed, either with a national patent office (such as the USPTO) or directly with the World Intellectual Property Organization (WIPO). This application establishes a priority date for all member countries.
International Search Report: After filing, a search report is generated to evaluate prior art, giving applicants an early assessment of patentability in various countries.
National Phase Entry: Within 30 months of the priority date, applicants must choose which countries to pursue full patent rights in and file individual applications in each country, completing the patent process in each selected jurisdiction.
Example: A company developing a groundbreaking medical device might file a PCT application to secure an international priority date, then use the subsequent months to assess which regions have the most commercial potential.
After market analysis, the company may choose to file in the U.S., EU, Japan, and China for full patent protection.
International Patents in Competitive Industries
In industries where innovation moves quickly and cross-border competition is intense, international patents provide a crucial advantage by securing rights in key global markets.
Pharmaceuticals and Biotech: Companies in pharmaceuticals use international patents to protect drug formulations and medical treatments, as global protection is essential in high-demand markets.
Technology and Electronics: Tech companies often pursue international patents for new software, electronics, and hardware, ensuring exclusivity in multiple high-tech regions like the U.S., EU, and Asia.
Renewable Energy: In the renewable energy sector, companies filing international patents can secure rights to new green technologies, such as efficient solar cells or energy storage solutions, in regions moving toward sustainable solutions.
Key Takeaway: In globalized industries, international patents allow businesses to protect their technology in markets that offer the greatest potential for growth and profit, helping them stay ahead in multiple regions.
Challenges and Considerations for International Patents
While international patents offer valuable protection, they come with specific challenges that businesses must consider:
Cost and Complexity: Filing in multiple countries can be costly, especially when considering the national phase fees, translations, and local patent attorneys required for each jurisdiction.
Varying Patent Laws: Each country has unique patent laws and standards for patentability, meaning an invention eligible in one country may face additional challenges elsewhere.
Enforcement Challenges: Enforcing patents internationally can be complex, as each country handles patent litigation and enforcement differently. Businesses must be prepared for potential legal processes in each region.
Business Tip: Identify key markets early and develop an international patent strategy based on where the invention has the highest commercial potential.
Consider market demand, competitive landscape, and local IP laws to prioritize filings in regions that offer the most strategic benefit.
Real-World Example: Apple’s Global Patent Strategy for the iPhone
Apple’s extensive international patent strategy for the iPhone’s hardware and software components allowed the company to secure protection in key global markets.
By filing patents in the U.S., EU, China, Japan, and other regions, Apple ensured its exclusive rights to innovative features worldwide.
This approach also gave Apple the legal grounds to pursue infringement cases in multiple countries, reinforcing its position as a global leader in smartphone innovation.
Takeaway for Business Leaders: For products with global reach, filing international patents secures market protection on a worldwide scale, allowing companies to defend their innovations across borders and maintain a competitive advantage.
Maximizing the Value of an International Patent Strategy
To optimize the benefits of an international patent, businesses should take a strategic approach by targeting regions where the invention will have the most impact and securing patents in those countries.
Target Key Markets First: Identify the regions where the invention has high commercial potential or where competition is strongest, and prioritize filing patents in these areas.
Leverage PCT’s National Phase Timing: The PCT allows a 30-month period before entering the national phase. Use this time to refine the strategy, identify high-priority countries, and prepare for the national filing process.
Consider Licensing in Non-Core Markets: For countries where direct commercialization is not a primary goal, consider licensing agreements that allow local companies to use the invention, generating revenue without a full patent application.
Example: A clean energy company developing a novel battery might file a PCT application to protect the technology internationally.
After determining which markets have the greatest demand for energy solutions, the company could enter the national phase in the U.S., EU, and Japan, and consider licensing in smaller markets.
Key Takeaways for Business Leaders
Global Market Protection: An international patent strategy offers protection across borders, allowing businesses to capitalize on their invention in multiple regions.
Strategic Market Entry: International patents allow companies to control where and how their inventions are commercialized, securing exclusive rights in high-potential markets.
Investor and Partner Appeal: International patent protection signals to investors and partners that the business has a strong IP strategy, especially for technologies with global applications.
