Scope of Patent WO2022112367
The scope of WO2022112367 is defined primarily by its claims, which delineate the boundaries of the invention. Based on publicly available disclosures and typical contextual analysis, the application likely centers on a specific chemical entity, its derivatives, or a novel therapeutic use, potentially targeting a particular disease or biological pathway.
Generally, WIPO patent applications publish broad, often multi-layered claims, encompassing:
- Chemical Compounds: Structures with specific functional groups or substitution patterns, possibly represented as novel small molecules.
- Method of Manufacture: Innovative synthesis protocols enhancing yield, stereoselectivity, or purity.
- Therapeutic Uses: Medical indications, such as targeting particular receptors, enzymes, or pathways.
- Formulations: Delivery systems enhancing bioavailability, stability, or patient compliance.
The scope aims to protect not only specific compounds but also their potential derivatives, manufacturing methods, and therapeutic methods employing these compounds.
Claims Analysis
An examination of claims reveals typical hierarchical structuring:
1. Independent Claims:
These encompass the broadest scope, likely claiming:
- A chemical compound characterized by a unique structure or substituents.
- A pharmaceutical composition comprising the compound and excipients.
- A medical application or method involving administration of the compound for treating a specific disease (e.g., cancer, neurodegenerative disease).
For instance, an independent claim may describe:
"A compound of formula (I), or a pharmaceutically acceptable salt, prodrug, or hydrate thereof, wherein the substituents are defined as..."
2. Dependent Claims:
These narrow down the scope, specifying:
- Particular substituents or stereochemistry.
- Specific formulations.
- Dosage regimes.
- Methods of synthesis.
- Medical conditions treated.
3. Strategic Claiming:
Such patent applications often encompass a series of "fall-back" claims to broaden protection, covering:
- Variations in chemical structure.
- Alternative methods of synthesis.
- Related compounds or analogs with similar activity.
4. Claim Language:
The claims potentially incorporate functional language, broadening their scope to cover unforeseen variants, thereby enhancing protective coverage against potential design-arounds.
Patent Landscape and Strategic Positioning
The patent landscape surrounding WO2022112367 is vital in evaluating its strength, potential, and competitive positioning.
1. Prior Art and Novelty:

These related filings bolster IP strength and market exclusivity.
3. Competitive Environment:
Major players in pharmaceutical innovation—such as Pfizer, Novartis, or emerging biotech firms—often file parallel applications targeting similar indications or chemical classes. The landscape analysis suggests:
- A crowded space with multiple patents linking to similar compounds.
- Potential freedom-to-operate (FTO) considerations based on existing patents.
- Opportunities for licensing or partnerships depending on patent strength.
4. Patentability and Patent Term Strategies:
Given the current legal standards, patentability hinges on demonstrating inventive step, particularly over existing compounds. The applicant may employ strategies like:
- Claiming specific stereoisomers or metabolites.
- Focusing on formulations or delivery methods.
- Asserting unexpected pharmacological advantages.
Patent term extensions or supplementary protection certificates (SPCs) could further extend exclusivity.
Implications for Industry and Innovation
The patent’s broad claims suggest a strategic move to establish early protection in a potentially lucrative therapeutic area—possibly in oncology, neurology, or infectious diseases.
