Vietnam Patent Guide: Mastering Priority Claims with PCT

1. Understanding Priority Claims in Vietnam

In the world of patents, the concept of "priority date" plays a pivotal role in establishing the novelty of your invention. This section delves into the significance of priority claims within the Vietnamese patent system.

The Power of Priority Date:

The priority date refers to the filing date of your very first patent application for a specific invention, anywhere in the world. This date becomes the benchmark for determining your invention's novelty in subsequent patent applications filed in Vietnam or other countries. Essentially, it establishes the starting point for assessing whether your invention was truly new and original at the time of filing.

Vietnam and the Paris Convention:

Vietnam is a signatory to the Paris Convention for the Protection of Industrial Property. This international treaty grants inventors a valuable right – the right of priority. Here's how it works:

• You file an initial patent application for your invention in any member country of the Paris Convention (including Vietnam).
• Within 12 months of that initial filing date, you can file subsequent applications for the same invention in other member countries, including Vietnam.

Benefits of Claiming Priority in Vietnam:

Claiming priority in Vietnam through a previous international application offers several advantages:

• Secures an earlier filing date: This strengthens your claim to novelty by establishing an earlier starting point for novelty assessment compared to applications filed by others after your priority date.
• Provides additional time: The 12-month grace period after your initial filing allows you to gather resources, conduct market research, and strategically decide in which countries, including Vietnam, you wish to pursue patent protection.
• Allows for flexibility: This flexibility is particularly valuable during the early stages of invention development. You can file an initial application to secure your priority date while further refining your invention before filing subsequent applications in Vietnam or other countries.

Important Considerations:

• Strict Timelines: Ensure you adhere to the 12-month window for claiming priority in Vietnam. Missing this deadline can jeopardize your ability to claim an earlier filing date.
• Absolute Novelty: Vietnam's patent law adheres to the concept of "absolute novelty." This means your invention cannot have been publicly disclosed anywhere in the world before your priority date (or Vietnamese filing date if no priority is claimed).

By understanding the power of priority claims and adhering to the relevant regulations, you can effectively establish your invention's novelty and pave the way for robust patent protection in Vietnam.

2. The Patent Cooperation Treaty (PCT): A Gateway to Global Protection

The PCT offers a streamlined and strategic approach for inventors seeking patent protection for their inventions in multiple countries. Established in 1970, the PCT simplifies the international patent application process, providing a gateway to global protection for your intellectual property.

Core Functionalities of the PCT:

• Single Application for Multiple Countries: The PCT allows you to file a single "international" patent application, acting as a substitute for filing individual applications in each desired country. This reduces administrative burdens and upfront costs associated with international patent filings.
• International Search and Opinion: The PCT facilitates an international search conducted by a designated International Searching Authority (ISA). This search identifies relevant prior art (existing published inventions) that might impact the patentability of your invention. Additionally, a written opinion is issued by the ISA, offering a preliminary assessment of your invention's potential to meet patentability criteria.

Benefits for Applicants:

• Extended Decision Time: The PCT provides up to 18 additional months compared to traditional filing methods to decide in which countries you wish to pursue patent protection. This valuable time allows for further market research, strategic planning, and resource allocation.
• Enhanced Certainty: The international search report and written opinion offer valuable insights into the patentability landscape for your invention. This information helps you make informed decisions about pursuing national phase applications in specific countries.
• Streamlined National Phase Entry: The PCT simplifies the national phase entry process, where you convert your international application into national applications in designated countries. The international search report is typically accepted by national patent offices, reducing duplication of search efforts.
• Reduced Costs: While national filing fees apply in each designated country, the PCT offers a single international filing fee, potentially reducing overall costs compared to filing individual national applications.
• Fast-Track Options: Several PCT member countries offer fast-track patent examination procedures for applications entering the national phase through the PCT.

Additional Advantages:

• Formal Requirements Met: A PCT application that meets PCT formality requirements cannot be rejected on those grounds during the national phase in designated countries.
• Improved Transparency: International publication of your PCT application on PATENTSCOPE raises awareness of your invention and can be a valuable tool for attracting potential licensees.
• Flexibility: The PCT offers optional stages, like the international preliminary examination, allowing you to refine your application before entering the national phase in different countries.

The PCT: A Global Solution

The PCT is a widely adopted system used by major corporations, research institutions, and universities worldwide. It simplifies the complexities of international patent filing, reduces costs, and offers valuable tools for informed decision-making throughout the patent process. Whether you're a Vietnamese inventor or an entrepreneur seeking global protection, the PCT can be a powerful asset in securing robust patent protection for your inventions.

3. Leveraging PCT for Priority Claims in Vietnam

The PCT offers a powerful tool for Vietnamese inventors seeking patent protection not only globally but also strategically within Vietnam itself. Here's how the PCT can be effectively used to leverage priority claims in Vietnam's patent system.

The National Office of Intellectual Property (NOIP) and PCT Procedures:

• Receiving International Applications: The NOIP acts as the designated office for receiving international applications originating in Vietnam.
• Language Requirements: International applications filed with the NOIP must be submitted in English with three copies.
• Designated vs. Elected Offices: Vietnam can be designated or elected in a PCT application. As a designated office, the NOIP automatically processes the application for entry into the national phase. As an elected office, the applicant actively chooses Vietnam during the national phase.

Entering the National Phase in Vietnam:

For both designated and elected Vietnam in a PCT application, specific requirements exist for entering the national phase:

• Timeline: The applicant has 31 months from the priority date to submit the necessary documents to the NOIP.
• Required Documents:
  • Written declaration requesting invention registration.
  • Copy of the international application (if requested before international publication).
  • Vietnamese translation of the application description, claims, drawings, and abstract.
  • National fees.

Late Entry and Additional Requirements:

• Late entry within six months after the deadline is possible with additional fees.
• International preliminary examination report translations might be required for elected Vietnam.

Claiming Priority in Vietnam:

• To claim priority from a previous application, the applicant must reaffirm this claim in the written declaration and pay the priority claim fee.
• Vietnamese translations of relevant documents supporting the priority claim might be requested by the NOIP.

Benefits of Leveraging PCT for Priority Claims in Vietnam:

• Extended Decision Time: The PCT offers 18 additional months compared to a direct national filing, allowing for strategic planning before entering the national phase in Vietnam.
• Enhanced Certainty: The international search report provides valuable insights into the patentability of your invention in Vietnam.
• Streamlined Process: The PCT simplifies the national phase entry process by establishing a single set of requirements for most PCT member countries, including Vietnam.

By understanding the procedures and effectively utilizing the PCT, Vietnamese inventors can strategically claim priority and gain a competitive edge in securing robust patent protection for their inventions in Vietnam and other countries.

5. Best Practices for Vietnamese Inventors Using PCT

The PCT offers a strategic pathway for Vietnamese inventors to secure patent protection for their inventions not only globally but also within Vietnam. Here are some key best practices to consider when using the PCT:

Understanding Patentable Subject Matter:

• "Use" Claims: Vietnamese patent law currently excludes "use" claims from patentability. These claims, often formatted as "use of product X for..." or "Swiss-type" claims, might be challenged during the national phase. Consider revising such claims to focus on the product or process itself (e.g., "the composition for use as..." or "a method for...").
• Computer Programs: While the software itself isn't patentable in Vietnam, computer-implemented inventions can be. Ensure your invention leverages the technical effect of the program running on a computer, not just the software itself.

Leveraging the Benefits of the CPTPP:

• 12-month Grace Period for Novelty Disclosure: The Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP) offers a 12-month grace period in Vietnam. Disclosing your invention within 12 months before filing won't necessarily jeopardize its novelty. However, this benefit excludes applications claiming priority from earlier filings.

Strategic National Phase Entry:

• Conversion to Utility Model Applications: If the international search report or examination raises concerns about the invention's inventive step (non-obviousness), consider entering the Vietnamese national phase anyway. You can explore converting the PCT application into a utility model application during the national phase, offering an alternative form of intellectual property protection.
• Time Limits: The deadline for entering the Vietnamese national phase for PCT applications is 31 months from the priority date, not 30 months. There's no longer a six-month grace period for late entry after this deadline.

National Phase Considerations:

• Government Fees: Patent application fees in Vietnam are based on the number of independent claims, not the total number of claims.
• Patent Family Strategy: Providing information about granted patents in other countries, particularly the US, EU, or Japan (patent family status), can expedite the Vietnamese patent examination process. This approach aligns with Vietnam's Patent Prosecution Highway (PPH) initiatives and highlights the global relevance of your invention.
• Annuity Payments: An annual fee (annuity) is required to maintain your Vietnamese patent's validity, starting from the first year. There's a grace period for late payments with a penalty. However, a unique practice exists where the first-year annuity is paid along with grant and registration fees upon receiving a notice of allowance. This means the deadlines for subsequent annual payments differ from the first year.

By following these best practices and strategically utilizing the PCT, Vietnamese inventors can effectively navigate the Vietnamese patent system and secure robust protection for their inventions. Remember to consult with a Vietnamese patent attorney for comprehensive guidance throughout the PCT process and national phase entry in Vietnam.
