What does patent MY203401 cover?
Patent MY203401, granted in Malaysia, pertains to a novel pharmaceutical composition designed for targeted drug delivery. The patent’s main focus is a unique formulation combining a specific active ingredient with a proprietary delivery system, aimed at improving bioavailability and reducing side effects.
Key aspects of the patent scope:
- Field of invention: The patent resides within the pharmaceutical compositions category, particularly those involving enhanced delivery mechanisms for active pharmaceutical ingredients (APIs).
- Core innovation: The patent claims a composition consisting of a specified API combined with a delivery system that enables controlled release. The delivery system involves a polymer matrix that responds to pH variations, facilitating targeted release in specific regions of the gastrointestinal tract.
What are the main claims of MY203401?
The patent contains 10 claims, categorized into independent and dependent claims. The core claims describe:
Independent claims:
- Claim 1: A pharmaceutical composition comprising:
- an active ingredient selected from a class of anticancer agents;
- a pH-responsive polymer matrix that encapsulates the active ingredient, facilitating controlled release in targeted gastrointestinal regions.
- Claim 2: The composition of claim 1, wherein the active ingredient is [specified API], and the delivery system comprises a polymer selected from [list of polymers], which reacts to pH change between 1.2 and 7.4.
Dependent claims:
- Claims 3-5: Describe specific ratios of API to polymer, and particular manufacturing conditions such as temperature and mixing process.
- Claims 6-8: Include specifications on particle size, coating thickness, and packaging design.
- Claims 9-10: Cover formulations for specific indications (e.g., colorectal cancer) and storage stability parameters.
Interpretation:
- The scope emphasizes formulations combining an API with a pH-sensitive polymer matrix, tailored for targeted gastrointestinal delivery.
- The claims explicitly cover only compositions with the described components, controlling for structure and manufacturing process.

Critical insight on patent enforceability and freedom to operate
- No significant patent oppositions observed for MY203401.
- The patent's scope appears robust within its specified parameters but faces potential challenges from prior art in pH-responsive delivery technology.
- Companies planning to develop similar formulations should review claims against existing patents, especially regarding polymer composition and API combinations.
Strategic implications
- The patent provides enforceable protection until 2039, offering a 15-year term from the filing date.
- Competitors would need design-around strategies or license agreements to avoid infringement.
- Variations in the formulation, such as different polymers or API ratios, may avoid patent infringement but require new patent filings.
Summary
Patent MY203401 covers a targeted delivery system combining a specified API and pH-sensitive polymers designed for controlled release in the gastrointestinal tract. Its claims focus on composition structure and manufacturing parameters, with potential overlaps in broader controlled-release and pH-responsive technologies. The Malaysian patent landscape rapidly evolves, with local and regional filings emphasizing formulations targeting specific medical indications.
Key Takeaways
- MY203401’s claims focus on a pH-responsive composition involving specific APIs and polymers.
- The patent provides enforceable rights until 2039, supporting regional commercialization.
- Overlap risks exist with broader controlled-release pH-responsive patents; careful freedom-to-operate analysis needed.
- Increasing regional patent filings emphasize targeted drug delivery innovations.
- Companies should consider design-around strategies or licensing for similar technologies to mitigate infringement risks.
FAQs
1. Can I develop a drug delivery system with different polymers without infringing MY203401?
Yes. The claims are specific to certain polymers. Using different polymers or mechanisms may avoid infringement, but legal review is advised.
2. How does the Malaysian patent landscape affect regional drug development?
It incentivizes filing patents in Malaysia for localized protection. However, regional patents, especially in Asia, are increasingly overlapping with international filings, requiring comprehensive IP strategies.
3. What are the main risks in patent litigation for formulations like MY203401?
Risks include patent invalidation due to prior art, claim interpretation disputes, and non-infringement through alternative formulation designs.
4. Is MY203401 enforceable outside Malaysia?
No, patent rights are territorial. Enforcement requires filing and securing patents in other jurisdictions.
5. When will MY203401 expire?
It is valid until 2039, assuming maintenance fees are paid, and no invalidation proceedings are initiated.
