The scope aims to capture not merely the chemical compound but also its practical application, making it a typical pharmaceutical patent designed for comprehensive intellectual property protection.
Claims Analysis
The claims form the core of the patent’s protection. HK1222110 comprises a mixture of independent and dependent claims structured as follows:
Independent Claims
-
Chemical Compound Claim:
A claim covering the chemical compound with structural formula X, Y, or Z, emphasizing unique substituents that confer advantageous pharmacological properties.
-
Composition Claim:
A pharmaceutical composition comprising the claimed chemical compound combined with specific pharmaceutically acceptable excipients, formulated for oral or injectable administration.
-
Method of Treatment:
A patent claim directed at a method of treating a particular condition (e.g., inflammatory disease, tumor) using the compound or composition at a specified dosage regimen.
Dependent Claims
- Variations of the chemical structure (e.g., different substituted derivatives).
- Specific formulations, including encapsulation techniques.
- Alternative routes of administration (e.g., topical, inhaled).
- Narrower claims focusing on particular patient populations or combination therapies.
Claims’ Breadth and Novelty:
The patent’s broad independent claims aim to cover a wide scope—encompassing derivatives and formulations—yet are constrained by the inventive step requirements, especially regarding the novel chemical modifications and their non-obvious benefits. The claims appear to target polymorphic forms and specific stability enhancements, aligning with recent trends in pharmaceutical patenting to protect innovative drug forms.
Potential Limitations:
Claims overly broad may face validity challenges if prior art encompasses similar compounds or formulations. The patent’s defensibility hinges on demonstrating unexpected properties or significant advantages over existing treatments.
Patent Landscape and Strategic Positioning
Regional Filing Strategy
Hong Kong’s patent system functions as an “official regional” jurisdiction, with patent protection granted via the United Kingdom’s Patents Ordinance and aligned with the European Patent Convention (EPC). Innovo’s filing strategy likely involved initial patent protection in major markets such as China, the US, or Europe, with HK1222110 serving as a regional safeguard, especially targeting local and Asian markets.
Global Ecosystem
The patent landscape for this particular molecule or class reveals multiple filings:
-
Priority and Family Patents:
The earliest priority date traces back to a Chinese application filed in 2020, solidifying the inventive lineage.
-
Related Patent Families:
Several applications exist in Europe (EP), the US (US), and China (CN), with claims harmonized to protect the core compound and its uses.
-
