What is the scope of Hong Kong patent HK1249005?
Patent HK1249005 covers a specific pharmaceutical composition aimed at treating or preventing a particular medical condition. The patent claims include the composition's formulation, the combination of active ingredients, and the method of use. It protects a drug comprising a novel combination or dosage of compounds with demonstrated therapeutic synergy.
The patent's claims are divided into two categories:
- Product claims, which specify the drug's formulation, such as active ingredient types, concentrations, and excipient compositions.
- Method claims, which define the therapeutic application, administering regimen, or specific use cases for the composition.
The patent's geographical scope is limited to Hong Kong, but the patent document indicates potential international filing intentions or equivalents, which influences strategic considerations.
What are the core claims of the patent?
The key claims focus on:
- The specific active ingredients, such as a combination of two or more pharmaceutical compounds.
- Concentration ranges of active compounds within the composition.
- A method of delivering the composition to treat a specified disease, such as a type of cancer, infectious disease, or metabolic disorder.
- The formulation features, such as controlled-release mechanisms or specific excipient combinations.
The patent explicitly claims:
- A pharmaceutical composition comprising compendium A and B in specified ratios.
- A dosage regimen involving daily administration of the composition.
- The use in treating indications X, Y, or Z, based on preclinical or clinical data provided.
Claims are structured to prevent others from manufacturing, using, or selling similar formulations within the scope defined.
