Understanding Post-dating and Anti-dating in Patent Applications

Understanding Post-dating and Anti-dating in Patent Applications

In the realm of intellectual property, particularly patent law, post-dating and anti-dating are crucial concepts that can significantly impact the patent’s priority date and overall protection. These terms refer to manipulating the filing date of a patent application—either by moving it forward (post-dating) or backward (anti-dating). Understanding how these concepts work, both in India and internationally, is essential for patent applicants to ensure compliance and maximize the protection of their inventions.


What is Post-dating?

Post-dating refers to the practice of changing the filing date of a patent application to a later date. This practice is legal in some jurisdictions under certain conditions, providing flexibility for the applicant to complete their application after the initial filing.


In India, post-dating allows applicants to request a later date for the patent filing, typically within six months of the original filing date, while still maintaining the priority of the application.


Reasons for post-dating:

Extra time for refining the invention.

Additional time for completing the patent documentation.

Correcting formalities or technical issues before proceeding with the full application.


What is Anti-dating?

Anti-dating is the opposite of post-dating—it refers to manipulating the filing date backward, i.e., claiming an earlier filing date than the actual date of filing. This is generally illegal because it can mislead the patent office, creating false records that could unfairly alter the scope of patent protection.


In India, anti-dating is prohibited and is considered a form of fraud.

  • Risks of anti-dating:
  • The patent can be revoked if the authorities discover the manipulation.
  • Legal consequences may include penalties and loss of intellectual property rights.

Example of Post-dating in India:

Let’s consider a scenario in India to understand post-dating more practically:


Example:


Suppose an inventor, Raj, files a provisional patent application for a new type of electric vehicle (EV) battery on January 1, 2023. The provisional application serves as a placeholder to protect Raj’s invention while he works on refining the technology. According to Indian patent law, Raj has 12 months from this date to file the complete specification. However, Raj needs more time for research and development to complete the testing of the battery's efficiency.


Raj applies for post-dating his complete specification to July 1, 2023, providing him with an extra six months to refine his invention.

The Indian Patent Office (IPO) allows Raj to request post-dating under Section 9(4), as long as he submits the complete application within 18 months from the provisional filing (i.e., by July 1, 2023).

Raj complies with the legal framework and successfully files the complete specification with a priority date of January 1, 2023. The post-dating gives Raj more time without losing priority.

This example demonstrates how post-dating can help an inventor buy more time, while still preserving the original filing date for the purpose of patent protection.


Laws on Post-dating and Anti-dating in Other Countries

While post-dating and anti-dating are handled differently around the world, many countries have similar rules to ensure the integrity of the patent system. Below is an overview of the laws related to post-dating and anti-dating in several key countries:


1. United States

Post-dating: In the U.S., post-dating is not explicitly allowed, but applicants can claim priority under the Paris Convention if they file in another country within 12 months of the provisional filing, which can effectively extend the filing date. The U.S. patent system allows for provisional applications, and applicants can convert them into non-provisional applications at any time before the 12-month period ends.

Anti-dating: Anti-dating is illegal in the U.S. Under 35 U.S.C. § 102, any attempt to change the filing date to an earlier time is considered fraudulent and could lead to the invalidation of the patent.

2. European Union (EPO)

Post-dating: The European Patent Office (EPO) allows for a post-dating of an application in limited circumstances, such as when the applicant fails to file a complete patent application on time but requests a later filing date. However, the request must be justified, and the application must still comply with the EPO’s filing rules.

Anti-dating: Anti-dating is strictly prohibited under the European Patent Convention (EPC). Filing a patent application with a false priority date can lead to serious legal repercussions, including the refusal of the patent application.

3. United Kingdom (UK)

Post-dating: Similar to the EPO, post-dating is allowed under certain conditions, such as filing an incomplete application. The UK Intellectual Property Office (UKIPO) has specific procedures for applicants to request an extended filing period, though the reasons must be valid.

Anti-dating: Anti-dating is prohibited in the UK, and any attempt to manipulate the filing date is considered an offense under the Patents Act of 1977. The UKIPO will reject any application that attempts to falsely modify the filing date.

4. Australia

Post-dating: In Australia, post-dating can be allowed under specific circumstances, such as when an applicant is late in filing the complete specification. However, the post-dating must comply with Australian patent law requirements, and the application must still be filed within 12 months from the provisional filing.

Anti-dating: As in most countries, anti-dating is strictly prohibited. Under Section 39 of the Patents Act 1990, it is illegal to backdate a patent filing.

5. Japan

Post-dating: Japan has provisions for post-dating in certain cases, such as for applicants who fail to submit the complete application on time but wish to keep their earlier priority date.

Anti-dating: Anti-dating is illegal in Japan under the Patent Act. Falsifying the filing date could result in criminal penalties and the invalidation of the patent.

Conclusion

Post-dating and anti-dating are terms that deal with the manipulation of patent filing dates, and while post-dating is allowed in certain jurisdictions under controlled conditions, anti-dating is universally prohibited due to its fraudulent nature. Applicants should be mindful of the specific laws and regulations in their respective countries to avoid legal complications and ensure the proper protection of their intellectual property.


Post-dating can be a helpful tool when used correctly, offering additional time for an applicant to file a complete application without losing priority.

Anti-dating not only jeopardizes the integrity of the patent system but can also result in severe legal and financial consequences for the applicant.

Before making any decisions regarding filing dates, it is always advisable for patent applicants to consult with intellectual property professionals to ensure compliance with national and international patent laws.

Understanding the America Invents Act: Strict Novelty Provisions and Post-Grant Review

Strict Novelty Provisions and Post-Grant Review    The America Invents Act (AIA), passed in 2011, brought significant changes to the U.S. patent system, including modifications to the novelty provisions and the introduction of new post-grant review mechanisms. The impact of these changes cannot be overstated, as they have reshaped patent practices and litigation in the United States, making it crucial for patent applicants and holders to understand the law's nuances.   The Core of Novelty: What Changed Under the AIA? Under the pre-AIA system, the U.S. followed a "first-to-invent" system, where inventors who could prove they were the first to conceive and reduce to practice an invention were granted the patent. However, the AIA shifted the system to a "first-to-file" approach, aligning the U.S. with the rest of the world’s patent systems.   Novelty Under the AIA The AIA introduced stricter rules for novelty, and today, an inventor must file a patent...
