Expanding Horizons: The Need for Globalizing Patents

In today’s global economy, protecting an invention in just one country might not be enough. As businesses operate across borders, the strategic protection of intellectual property must also traverse international lines. Globalizing patents becomes essential to safeguarding a company’s assets and maintaining its competitive edge on the world stage. 

This article aims to elucidate why it is crucial for businesses to consider taking their patents global and how they can effectively implement this strategy. We will explore both the strategic advantages and the practical steps involved in global patent protection, providing insights to help businesses maximize their intellectual property’s potential in the global market. 

Why Take Your Patents Global 

I) Enhancing Competitive Advantage 

Securing International Market Share 

The world is more connected than ever, and businesses that seek substantial growth must think beyond their domestic markets. Global patents secure a company’s foothold in international markets by ensuring that no other entity can replicate their innovations.  

II) Financial Benefits 

Leveraging Licensing and Royalties 

Patents are not just about protecting innovations; they are also crucial in generating revenue through licensing agreements and royalties.  

By holding patents in multiple countries, a business can monetize its inventions across the globe, creating a continuous stream of income. For example, pharmaceutical companies often see substantial revenue boosts by securing patents in major markets worldwide. 

III) Mitigating Risks 

Combatting Infringement in Competitive Markets 

The threat of intellectual property theft looms large, especially in highly competitive sectors like technology and manufacturing.  

Global patents serve as a deterrent to competitors who might otherwise infringe on innovations, thereby securing market integrity. This section would also discuss the legal and business repercussions of not protecting innovations on a global scale, potentially leading to significant financial and market share losses. 

IV) Fostering Innovation and Collaboration  

Encouraging Global Partnerships 

International patents can pave the way for collaborations across borders, offering companies the confidence to share ideas and resources without the fear of losing proprietary rights.  

These collaborations can accelerate research and development efforts, leading to more rapid and diverse innovation. This can be illustrated by partnerships in the automotive industry where companies collaborate on technology like electric vehicles and autonomous driving systems. 

How to Take Your Patents Global 

I) Understanding International Patent Systems

Navigating the Patent Cooperation Treaty (PCT) 

The Patent Cooperation Treaty (PCT) is a pivotal framework for patent applicants looking to secure protection in multiple countries through a single application process.  
This treaty simplifies the initial filing and assessment stages, allowing applicants to delay individual country expenses until they can gauge an invention’s commercial viability. Understanding the PCT’s timelines and strategic advantages is essential for effective global patent management. 

Recognizing Regional Differences 

Different regions have unique patent laws and procedures, which can significantly affect the scope and strength of patent protection. For instance, the United States Patent and Trademark Office (USPTO) and the European Patent Office (EPO) have different examination processes and criteria for patentability. Familiarity with these nuances is crucial for tailoring patent strategies to specific markets. 

II) The Strategic Decision-Making Process 

Selecting Inventions for Global Patents 

Not all inventions warrant global patent protection due to varying factors like market potential, legal feasibility, and strategic business alignment. Companies must assess which inventions have enough commercial promise and technological relevance across international markets to justify the costs and effort of global patents. 

Evaluating Target Markets 

Identifying and analyzing target markets is critical. Factors such as market size, growth potential, local competition, and legal environment must be considered. This evaluation helps prioritize countries where obtaining patent protection could be most beneficial and strategically advantageous. 

III) The Application Process  

Filing International Patent Applications through PCT 

The Patent Cooperation Treaty (PCT) process is designed to streamline the filing of patents in multiple countries through a unified procedure. This system allows inventors to initiate protection for an invention in a large number of countries simultaneously by filing a single “international” patent application. Here’s a detailed look at the key steps involved in the PCT process: 

  1. Filing the International Application
    • Initial Submission: The process begins with the filing of an international application, usually based on a national patent application (the “priority application”). This application can be filed with a national patent office (as the Receiving Office), the International Bureau of the World Intellectual Property Organization (WIPO), or a regional patent office (like the EPO). 
    • Designating Countries: At the time of filing, the applicant must designate all member countries in which they might eventually seek patent protection. 
  1. International Search
    • Search Report: After the application is filed, an International Searching Authority (ISA) conducts a search of the relevant technology to identify prior art that may affect the patentability of the invention. 
    • Written Opinion: Along with the search report, the ISA issues a written opinion on the potential patentability of the invention, which includes assessments of novelty, inventive step (non-obviousness), and industrial applicability. 
  1. International Publication
    • Publication of the Application: Approximately 18 months after the priority date (the filing date of the initial national application), the international application is published by the WIPO. This publication includes the patent application and the search report, making the information accessible to the public and potentially deterring infringement early on. 
  1. Supplementary International Search (Optional)
    • Additional Searches: If desired, the applicant can request an additional search by a second ISA, focusing on literature not covered in the initial search, to further clarify the patentability of the invention. 
  1. International Preliminary Examination (Optional)
    • Request for Examination: After the search phase, the applicant can request a preliminary examination, conducted by one of the ISAs, to receive a more detailed analysis of the patentability of the invention. 
    • Amendments: During this phase, the applicant has the opportunity to amend the application to address any issues raised in the written opinion of the ISA. 
  1. National Phase Entry
    • Entering National Phases: After the international phase, the next major step is entering the national phase, where the applicant seeks patent protection in individual designated countries. 
    • National Requirements: Each designated country will conduct its examination process, requiring compliance with its specific legal requirements, which may include translations of the application and additional fees. The deadlines for entering the national phase typically occur 30 or 31 months from the priority date. 
  1. Granting of Patents
    • If the national phase applications meet the respective patent office’s criteria, the patent is granted for each jurisdiction where the application has succeeded. This is the final step where the patent becomes enforceable in those countries. 

IV) Other Options Aside From PCT 

Besides using the Patent Cooperation Treaty (PCT) to file patents internationally, there are other pathways and strategies that inventors and companies can consider for securing their inventions globally. Understanding these alternatives can help tailor a patent strategy that best suits the business objectives and market dynamics of each inventor. 

Direct Filing (Paris Convention Route) 

1. Paris Convention for the Protection of Industrial Property

Instead of using the PCT, inventors can file directly in each country where they seek protection. The Paris Convention, established in 1883, allows inventors to file a patent application in any of the member countries within 12 months from the filing date of the first application.  
This right is known as the “right of priority” and ensures that the subsequent filings are considered to have been filed on the same day as the initial application. This method requires more coordination and often faster decision-making, as the application must be translated and adapted to meet the specific legal requirements of each country within the one-year timeframe. 

Regional Patent Systems 

2. European Patent Office (EPO)

The EPO allows inventors to seek patent protection in up to 38 European countries through a single application process. While the EPO is not a PCT-based system, it streamlines the application process across its member states. Once the EPO grants a patent, the patent must be validated in each country where protection is desired, which may involve translations and other national requirements.

3.  African Regional Intellectual Property Organization (ARIPO)

ARIPO provides a similar system for multiple African countries. By filing one application with ARIPO, inventors can seek protection in any of the member states. ARIPO then centrally administers the patent, reducing the complexity and potentially the cost of securing patent rights across multiple jurisdictions within Africa.

4. Eurasian Patent Organization (EAPO)

The EAPO offers a single application process for patent protection in several countries that are part of the Eurasian Patent Convention. Similar to the EPO, a patent granted by the EAPO takes effect in any of the member states specified in the application. 

Utility Models 

5. Utility Model Protection
In some countries, inventors can protect their inventions through utility models, which are often easier to obtain and require less rigorous novelty and inventive step than patents. Utility models are particularly popular in countries like Germany and China and offer a shorter term of protection than patents – typically between 6 and 15 years. This can be a strategic choice for inventions with a shorter commercial life. 

Choosing the Right Strategy 

The choice between these methods depends on several factors including the nature of the invention, the markets where the protection is most valuable, the costs involved, and the strategic importance of rapid protection versus broader, potentially longer-term patent coverage.  

Companies often use a combination of these methods to optimize their international intellectual property strategy, ensuring comprehensive protection aligned with their business goals and market presence. 

Challenges in Protecting Innovations Globally

While the benefits of securing global patents are significant, the process comes with its own set of challenges. Understanding these hurdles is crucial for companies to effectively navigate the complex landscape of international patent protection.

I) Navigating Diverse Legal Systems 

Understanding Varied Jurisdictions  

One of the primary challenges in global patenting is the diversity of legal systems and patent regulations across different countries. Each country has its own set of rules regarding what qualifies as patentable material, how patents are filed, processed, and enforced.  

This complexity requires companies to have a deep understanding or access to expertise on the nuances of each jurisdiction to avoid critical mistakes that could lead to the loss of protection. 

II) High Costs of Filing and Maintenance  

Managing Financial Resources 

Securing patents globally can be financially demanding. The costs include not only filing fees but also translations, attorney fees, and maintenance costs to keep the patents active.  

For many startups and smaller enterprises, these costs can be prohibitive, making it challenging to protect innovations in all desired markets. Strategic decisions must be made to balance potential returns against the costs of securing and maintaining patents worldwide. 

III) Language Barriers and Documentation 

Overcoming Communication Hurdles 

The need for translations and adapting documents to different languages adds another layer of complexity and potential for errors. Misinterpretations or inaccuracies in translation can lead to rejections or weak patent protection, significantly undermining the value of a patent.  

Ensuring high-quality translations and accurate legal documentation is crucial and often necessitates hiring specialized translation services and local legal advisors. 

IV) Keeping Pace with Rapid Technological Changes

Adapting to Innovation Speed 

In industries where technology evolves rapidly, the slow pace of the patenting process can be a significant drawback. By the time a patent is granted, the technology might have moved on, reducing the patent’s relevance and value. Companies need to continually assess the viability and timing of patent applications to ensure that they are protecting technology that remains cutting-edge and commercially viable. 

V) Future Trends in Global Patenting 

As we look to the future, several trends are poised to reshape the landscape of global patenting. These trends not only reflect technological evolution but also geopolitical shifts and advancements in artificial intelligence and machine learning. Understanding these trends will help businesses and innovators stay ahead in securing their inventions effectively and strategically. 

I) Technological Advancements and Their Impact

Driving Innovation Forward 

Emerging technologies are rapidly changing the way businesses approach research and development, and consequently, how they manage patent strategies. Technologies such as blockchain and the Internet of Things (IoT) are creating new paradigms for securing patentable innovations that are inherently global in nature.  

For instance, blockchain technology offers new ways to track patent filings and validate the authenticity of documents seamlessly across borders, potentially reducing the complexity of managing international patents. 

II) Geopolitical Factors 

Navigating Changing Legal Landscapes 

Geopolitical shifts can have profound effects on patent law and the strategies companies must adopt to protect their intellectual property. Trade agreements, regional conflicts, and changes in national patent laws can all influence where and how companies decide to file patents.  

For example, changes in trade relations between major economies like the USA and China may affect decisions about where to obtain patent protection or how to structure global patent portfolios to mitigate risks associated with political and economic instability. 

III) The Increasing Role of AI and Machine Learning 

Revolutionizing Patent Filings and Strategy

Artificial intelligence and machine learning are not only subjects of patents themselves but are also becoming integral to the patenting process. AI tools are increasingly used to predict patentability, analyze potential patent infringements, and even generate patentable material.  

As AI becomes more sophisticated, we can anticipate that it will play a crucial role in shaping patent strategies, helping companies to identify innovative opportunities faster and more accurately. 


Global patent protection is crucial in securing a company’s innovations and enhancing its competitive edge worldwide. Successfully navigating this complex landscape requires understanding diverse legal systems, managing costs, and keeping pace with rapid technological advancements.  

Strategic planning and adaptability are essential for leveraging global patents effectively in today’s interconnected economy.
