Patents are a cornerstone of innovation protection. In the United Arab Emirates (UAE), obtaining a patent provides exclusive rights to an invention, but those rights are not carved in stone. Once a patent is granted, it can be challenged through several legal mechanisms. Understanding these processes is essential for both innovators defending their rights and competitors seeking to challenge a patent.
This article explains the framework under UAE law for opposition, revocation, post-grant challenges, timelines, grounds, procedures, strategic considerations, and practical tips for both attacking and defending patent rights.
The Legal Framework for Patents in the UAE
Patents in the UAE are governed primarily by:
- Federal Law No. 11 of 2021 on the Regulation and Protection of Industrial Property Rights (“the Industrial Property Law”)
- Executive regulations issued thereunder; and
- Relevant decisions of the Ministry of Economy and judicial interpretation.
A patent is granted following examination of formalities and substantive criteria, including novelty, inventive step (non-obviousness), and industrial applicability.
However, the patent grant is not final. The law allows affected third parties and interested persons to challenge the validity of a patent under specific procedures.

Post-Grant Opposition: What it is and How it Works
Definition
Post-grant opposition is a legal proceeding initiated by a third party to challenge the validity of a patent after it has been granted but within a defined period.
Time Limit
Under UAE law, an opposition must be filed within 90 days from the date of publication of the patent grant in the official gazette. This is a strict deadline.
Who Can File an Opposition
Any person or entity with a legitimate interest may file an opposition. This typically includes:
- Competitors operating in the same technology domain
- Potential licensees
- Investors or business partners with commercial interests
- Organizations monitoring IP portfolios for validity
Grounds for Opposition
The grounds for opposition mirror the substantive requirements for patentability. The opponent must specify and prove that the patent fails one or more of the following:
- Lack of Novelty
The invention was already known or disclosed publicly before the filing or priority date. - Lack of Inventive Step (Obviousness)
The invention would have been obvious to a person skilled in the relevant art based on prior art. - Lack of Industrial Applicability
The invention cannot be made or used in any industry. - Insufficiency of Disclosure
The patent application does not enable a skilled person to carry out the invention. - Subject Matter Excluded from Patentability
Certain scientific theories, abstract ideas, purely aesthetic creations, and methods of doing business are excluded.
- Lack of Novelty
Opposition Process
- Filing
The opponent submits a formal opposition to the Ministry of Economy within 90 days, including evidence and arguments. - Notice to Patentee
The Ministry notifies the patentee, who has a chance to respond with counter-arguments and evidence. - Review and Decision
The Ministry examines submissions, may allow written hearings, and issues a reasoned decision to uphold, amend, or revoke the patent. - Appeal
Either party may appeal the Ministry’s decision to the Court of First Instance and subsequently to the Court of Appeal.
- Filing
Revocation Actions: Beyond the 90-Day Opposition Window
What is Patent Revocation?
Revocation is a broader challenge to the validity of a granted patent, usually after the opposition period has lapsed. Revocation typically proceeds through the UAE judicial system rather than directly within the Ministry.
When Can a Revocation Action Be Filed?
A revocation action can be filed at any time during the life of the patent (20 years from filing), subject to applicable procedures and rules of evidence.
Revocation is a civil action before the competent UAE courts. It is not limited to the 90-day opposition window.
Grounds for Revocation
The grounds for revocation are similar to opposition, and include:
- Lack of novelty
- Lack of inventive step
- Non-patentable subject matter
- Insufficient disclosure
- Prior public use or disclosure
- Clerical errors in priority claims
Because a revocation action is a court proceeding, evidence must be formally presented, witnesses may be called, and expert testimony can be important.
Strategic Differences Between Opposition and Revocation
| Aspect | Opposition | Revocation |
|---|---|---|
| Forum | Ministry of Economy | UAE Courts |
| Time Limit | Within 90 days of grant publication | Anytime during patent life |
| Burden of Proof | Lower formal thresholds | Higher evidentiary standards |
| Process | Administrative review | Judicial litigation |
| Appeals | Judicial appeal possible | Judicial appellate hierarchy |
| Strategic Use | Early nullification | Infringement defense or market strategy |
Opposition is tactical and cost-efficient. Revocation is a stronger, broader challenge that carries more legal weight but also requires deeper investment in evidence and litigation.
Defending Patent Rights in Opposition and Revocation Proceedings
Whether you are a patentee facing an attack or a challenger planning strategy, the following are key defensive considerations:
Timely Response and Preparation
- Respond promptly with well-structured legal arguments
- Gather prior art analysis, expert opinions, and technical evidence
- Demonstrate inventive step and novelty with clear explanations
Expert Evidence
Expert technical reports carry significant weight, especially in court proceedings. Engaging credible experts in the relevant field can strengthen your position.
Procedural Compliance
Strict compliance with filing deadlines and procedural formalities is critical. Missing a deadline can forfeit your right to oppose or defend.
Evidence Preservation
Maintain and preserve evidence supporting the invention’s development, drafting history, prototype documentation, and research summaries.
Using Revocation as aDefensein Infringement Cases
One common real-world scenario is where a competitor asserts infringement. In response, the alleged infringer may file a revocation action against the patent. If the patent is successfully revoked, the infringement claim falls away.
This makes revocation both a defensive and offensive tool in patent disputes.
Practical Tips for Challengers
Conduct Comprehensive Searches Early
Start your patentability and validity investigation early. Use professional patent search services and international databases.
Build Clear Evidence Trails
Organise all prior art and technical documentation chronologically. Pinpoint exact dates of disclosure to support invalidity arguments.
Leverage Expert Insights
Technical experts help translate complex inventions into clear legal arguments.
Consider Timing and Costs
Opposition is typically cheaper and faster. Revocation is more expensive and time intensive but can provide a definitive outcome.
Best Practices for Patentees
Prepare for Post-Grant Challenges
Expect challenges. Build a record of innovation, prototypes, research notes, experiment results, and design evolution.
Use Professional Drafters
High-quality drafting makes your patent stronger and reduces vulnerability to attack.
Monitor Competitor Activity
Patent monitoring helps you anticipate oppositions and react early.
Key Takeaways
- Post-grant opposition in the UAE must be filed within 90 days from patent publication.
- Revocation actions can be filed anytime and are adjudicated by UAE courts.
- Grounds for challenge include lack of novelty, inventive step, industrial applicability, and insufficient disclosure.
- Opposition is an administrative process; revocation is a judicial litigation.
- Strategic defence requires evidence, expert testimony, procedural precision, and proactive preparation.
Strategic Vigilance in Managing Patent Rights in the UAE
Patent protection in the UAE offers innovators a strong legal framework to secure exclusivity and commercial advantage. However, these rights are not absolute and remain subject to scrutiny at multiple stages whether through opposition mechanisms (where applicable), revocation actions, invalidity challenges, or post-grant enforcement disputes. The legal framework permits third parties to challenge patents on substantive grounds such as lack of novelty, lack of inventive step, insufficiency of disclosure, or non-patentable subject matter.
For patent holders, this means that obtaining a grant certificate is not the end of the journey but the beginning of a risk-management phase. Continuous monitoring of potential infringements, maintaining documentary evidence of development and ownership, ensuring proper recordal of assignments or licences, and preparing technical justifications to defend validity are critical components of a sustainable IP strategy. Weak drafting, inadequate disclosure, or procedural non-compliance can later expose a patent to revocation proceedings, significantly affecting enforcement strength and commercial negotiations.
For competitors or third parties, the legal framework also provides structured avenues to challenge improperly granted patents where they obstruct legitimate market entry. A well-prepared invalidation strategy supported by prior art evidence and technical analysis can effectively neutralise overbroad or vulnerable patents.
Ultimately, success on either side whether defending or attacking a patent depends on strategic planning, timely procedural action, and robust technical and legal evidence. Businesses operating in the UAE should therefore treat patents not merely as registration assets but as actively managed legal instruments requiring continuous oversight and informed legal guidance.
In Part 5 of this patent series, we will shift from validity challenges to enforcement strategy, covering how patent infringement is assessed in the UAE, available remedies, precautionary measures, and key strategic considerations for patentees when choosing between litigation, negotiation, or licensing.
