What Do Patent and Registered Design Rights Entail? (And Who Can You Enforce Against?)
When business owners and technology developers invest in intellectual property, they often focus on a single scenario: stopping a competitor from manufacturing or selling a direct copy of their product.
While targeting the supplier is a natural first step, IP protection goes much further. In Singapore, patent and registered design rights grant owners an exclusive monopoly over a wide spectrum of acts—meaning enforcement is not limited to manufacturers or sellers.
Understanding the full scope of these rights clarifies what you actually own, what acts constitute infringement, and who across the supply chain can be held responsible.
1. What Rights Do Patents and Registered Designs Grant?
Patents and registered designs grant exclusive negative rights that allow an IP owner to exclude others from commercially exploiting an invention or design in Singapore.
While both protect tangible products, machinery, components, and visual features, they safeguard fundamentally different aspects of an innovation:
- Patents: Protect how something works—functional mechanisms, chemical compositions, software algorithms, and operational processes.
- Registered Designs: Protect how something looks—the visual appearance, shape, configuration, pattern, or ornament applied to an article or graphical user interface (GUI).
In both cases, these IP rights function as a legal “negative right”. They do not automatically grant you the right to operate, but rather the legal right to prohibit third parties from exploiting your technology or design without your authorization.
2. The Scope of Infringement: Any Single Act Is Enough
Under Singapore IP law, direct infringement occurs whenever an unauthorized party performs any single one of the statutory acts—including making, selling, importing, using, or keeping the protected IP.
Specifically under Section 66 of the Singapore Patents Act and Section 30 of the Registered Designs Act, carrying out any ONE of the following acts in Singapore without the rights owner’s consent constitutes direct infringement:
- Make OR
- Import OR
- Sell / Offer for Sale / Hire OR
- Use / Possess (for sale, hire, or business use)
Because these statutory acts are independent, “Use” and “Possession” stand on equal legal footing with making or selling. Therefore, if a business buys an infringing item and deploys it in their commercial operations, that business is committing direct infringement—even if they played no role in manufacturing or importing the item.
3. Who Can Patent and Registered Design Owners Enforce Against?
An IP owner can enforce patent and design rights against any entity performing a restricted act within Singapore—including domestic manufacturers, local importers, distributors, and commercial enterprise users.
Because Singapore law penalizes every link in the chain of commercial exploitation, an IP owner can enforce their rights against multiple entities along the supply chain:
Domestic Manufacturers
- Basis: Making / Producing in Singapore
- Strategic Context: Direct source of the knockoff; stops production at the root.
Importers & Distributors
- Basis: Importing / Selling / Offering in Singapore
- Strategic Context: Controls entry points into local markets and commercial distribution channels.
Enterprise / Corporate Users
- Statutory Basis: Using / Possessing for business in Singapore
- Strategic Context: High-value local targets where foreign suppliers sit outside direct territorial jurisdiction.
Are Everyday Retail Consumers Liable for Infringement?
Technically, an individual consumer using a patented product without authorization is committing an infringing act. In practice, the law treats genuine and unauthorized sales differently:
- Legitimate Sales: When genuine products are purchased through authorized channels, an implied license (and the doctrine of exhaustion) protects the end buyer from infringement claim.
- Unauthorized Copies: Where a seller had no authority to sell the item, no implied license exists. While individual retail buyers are technically exposed, IP owners typically focus enforcement on commercial, enterprise, or high-volume entities rather than private consumers.
4. What Are the Practical Enforcement Strategies for IP Owners?
Knowing the full reach of patent and registered design rights allows IP owners to deploy flexible, high-leverage enforcement strategies:
- Overcoming Territorial Limits on Offshore Suppliers: Because Section 66 requires acts to occur in Singapore, foreign manufacturers often sit outside local jurisdiction. Enforcing against the domestic importers, distributors, or corporate end-users who perform the restricted acts within Singapore bridges this jurisdictional gap.
- Cutting Off Market Demand: Enforcing rights against key distributors or enterprise users starves an unauthorized supplier of their customer base, frequently resolving disputes faster than chasing an elusive offshore manufacturer.
- Encouraging Supply-Chain Due Diligence: Open dialogue or constructive notice regarding protected IP allows commercial users to review their vendor contracts, request indemnities, or verify that their supply sources are fully licensed before disputes escalate.
Key Boundaries to Remember
- Groundless Threats Protections: Under Section 77 of the Patents Act and Section 44 of the Registered Designs Act, sending baseless formal legal threats to third parties can expose you to legal counterclaims. Patent and design claims should always be evaluated by a patent attorney or a lawyer before issuing formal notices to vendors or third-party users.
Frequently Asked Questions (FAQ)
Can you sue a company for using an infringing machine or software in Singapore?
Yes. Under Section 66 of the Singapore Patents Act and Section 30 of the Registered Designs Act, unauthorized “use” within Singapore constitutes infringement. The user can be held legally liable even if they purchased the system from an independent or foreign vendor.
Can a local distributor or reseller be held liable if they did not manufacture the infringing product?
Yes. Importing, selling, offering for sale, or keeping infringing products for business purposes are independent acts of direct infringement under Singapore law. A local distributor or reseller is liable for these acts, regardless of whether they manufactured the goods or sourced them from a third-party vendor.
What are the risks of sending a cease-and-desist letter to a competitor’s customer?
Under Section 77 of the Patents Act and Section 44 of the Registered Designs Act, issuing groundless threats can expose you to counterclaims for damages. Before contacting third-party users or buyers, it is critical to have a patent attorney or lawyer review your IP claims to ensure your legal notice is properly grounded.

Intellectual property law in Singapore, specifically regarding interpretations of provisions like Section 66 of the Patents Act and Section 30 of the Registered Designs Act, is dynamic and subject to change.

Summary
Patent and registered design rights are comprehensive tools. By granting exclusive control over making, importing, selling, using, and possessing, IP owners have the flexibility to protect their commercial position at whichever point in the supply chain proves most effective.
