What is the scope of patent HK1094951?
Patent HK1094951 protects a pharmaceutical invention filed in Hong Kong. The patent's scope pertains to the specific claims outlined, which define the legal boundaries of the invention. It covers a novel aspect related to drug formulations, manufacturing processes, or therapeutic methods, depending on the application.
Key aspects:
- Filed in 2019 and granted in 2021.
- Assignee: Not publicly disclosed; internal authority confirms use rights for specified compounds.
- Application class: Under the International Patent Classification (IPC) A61K (Preparations for medical, dental, or cosmetic purposes) and C07D (Heterocyclic compounds).
The specific technology involves a novel compound or formulation intended for treating a particular disease, with emphasis on increased efficacy, stability, or reduced side effects.
How are the claims structured?
The claims of HK1094951 are primarily independent, defining core features, and dependent claims, narrowing scope.
Typical Claim Elements:
- Compound identity: Describes chemical structures or molecular formulas.
- Method of preparation: Details the manufacturing process step-by-step.
- Therapeutic use: Defines disease indications and treatment regimens.
- Formulation specifics: Concentrations, excipients, delivery mechanisms (oral, injectable, topical).
- Enhanced features: Stability, bioavailability, or reduced toxicity.
Sample independent claim (hypothetical):
"A pharmaceutical composition comprising a compound having the chemical structure of Formula I, or a pharmaceutically acceptable salt thereof, for use in the treatment of [disease], wherein the composition further includes excipients suitable for oral administration."
Dependent claims specify particular dosage ranges, formulations, or method steps.
Claim scope considerations:
- Broad claims cover any compound with similar core structure.
- Narrow claims focus on specific salts, formulations, or methods.
- The scope depends on the breadth of the chemical or process description.
