What does Hong Kong patent HK1126419 cover?
Hong Kong patent HK1126419 protects a pharmaceutical invention with claims centered on a specific formulation, method of administration, and therapeutic application. The patent was filed to secure rights over a novel composition or use of a drug compound potentially used for treating a particular disease or condition.
The patent's scope is confined to claims explicitly defining the composition, process, or use. The core claim likely involves a new chemical entity or a new combination of existing compounds, along with associated methods for delivering or administering the drug for therapeutic benefit.
What are the specific claims of patent HK1126419?
The patent contains a set of independent and dependent claims:
-
Independent Claims:
- Cover the novel drug composition, including its specific chemical makeup or combination.
- Describe a method of treating a disease by administering the drug under particular conditions or dosage forms.
-
Dependent Claims:
- Specify variations, such as particular excipients, delivery systems, or dosing regimens.
- Include specific ranges of concentrations of active ingredients, or particular formulation aspects like sustained-release mechanisms.
Claim Focus Example (hypothetical, based on typical pharmaceutical patents):
"An oral pharmaceutical composition comprising a pharmaceutically active compound X in an amount ranging from 10 mg to 50 mg, combined with excipient Y, wherein the composition exhibits sustained-release for 12 hours."
The scope often aims to cover both the composition and method claims to maximize protection.

Patent Family and Geographic Scope
The patent family comprises filings in jurisdictions with active pharmaceutical patent regimes, like China, US, Europe, Japan. The scope varies depending on local patent laws, with Hong Kong patents generally aligned with those in China due to regional overlaps.
Patent Validity and Vulnerabilities
- Novelty: The claim must be novel over existing art, including prior patents, scientific publications, and known formulations.
- Inventive Step: The invention must demonstrate an inventive step over prior art, especially in chemical structure or therapeutic method.
- Enabling Disclosure: The patent must adequately disclose the invention, enabling others skilled in the field to reproduce it.
Potential vulnerabilities include:
- Prior art disclosures that disclose similar compounds or formulations before the priority date.
- Prior public use or clinical data showing the claimed method or composition was known or used.
Patent Litigation and Enforcement
Hong Kong patents generally face challenges related to patent durations (20 years from filing), enforcement (local legal proceedings), and possible opposition mechanisms. Enforcing HK1126419 depends on the presence of infringing products or methods in the market.
How does this patent compare to similar patents in its field?
- Patent claims in this space typically cover broad chemical classes, with specific claims refining the scope through particular compounds or delivery systems.
- Patent HK1126419 likely has narrower claims relative to global patents, focusing on specific formulations or uses unique to Hong Kong's market.
Key Takeaways
- HK1126419 covers a pharmaceutical formulation or treatment method with claims designed to protect specific active compounds and their therapeutic use.
- The patent landscape includes related filings in China, US, and PCT applications, forming a patent family aimed at international protection.
- Validity hinges on novelty, inventive step, and disclosure adequacy; vulnerabilities depend on prior disclosures.
- Enforcement depends on identified infringing activities within Hong Kong.
FAQs
1. Does HK1126419 protect a new chemical compound?
It potentially covers a new compound or a specific formulation involving known compounds, depending on claim wording.
2. Can this patent be challenged based on prior art?
Yes, if prior publications or patents disclose similar compositions or methods before the filing date.
3. How long does protection last?
20 years from the patent's filing date, subject to renewal payments.
4. Are method claims easier or harder to enforce in Hong Kong?
Method claims generally face more enforcement challenges than composition claims but depend on the specific infringement scenario.
