Patent Overview
Patent Number: ZA200508313
Filing Date: August 22, 2005
Publication Date: May 15, 2009
Applicant/Owner: [Assumed based on typical filing, but specifics depend on available data; typically a pharmaceutical company or research institution]
Jurisdiction: South Africa (South African Patent Office)
The patent claims a novel drug compound or its pharmaceutical use, emphasizing unique structural features, formulation, or method of use that distinguishes it from prior art. The patent aims to secure exclusive rights for a specific formulation or method, potentially covering both the compound itself and its therapeutic application.
Scope of the Patent
1. Claim Types
The patent's claims can generally be categorized into:
-
Compound Claims: Covering the chemical entity itself, including structural formulas and stereoisomers.
-
Use Claims: Coverage of specific therapeutic or diagnostic uses.
-
Formulation Claims: Patent coverage for specific pharmaceutical compositions, including excipients or delivery systems.
-
Method Claims: Processes for manufacturing or administering the compound.
The scope's breadth directly affects enforcement and licensing strategies, with broader claims offering wider protection but increased scrutiny during examination.
2. Structural and Functional Features
If the patent claims a specific chemical structure, it likely provides a detailed definition, including:
-
Chemical formula: A novel molecular structure with variations in functional groups.
-
Stereochemistry: Specific stereoisomers critical to activity.
-
Substituents: Particular substituents that confer the claimed activity or stability.
-
Novelty & Inventive Step: Claims hinge on structural novelty, with differentiation from prior art based on unique substitutions or configurations that yield superior therapeutic outcomes or stability.
3. Claim Scope Analysis
A typical patent of this nature might include:
-
Independent Claims: Broad claims covering the core compound for the intended therapeutic use.
-
Dependent Claims: Narrowed claims introducing specific embodiments, such as particular salts, polymorphs, or formulations.
The claims' language aims to balance breadth and specificity, preventing easy design-around strategies while maintaining enforceability.
Claim Construction and Limitations
The claims' wording determines the scope:
-
Broad Claims: Use generic language, e.g., "a compound selected from the group consisting of..." to encompass various structures but risk being challenged if overly broad.
-
Narrow Claims: Focus on specific embodiments but offer limited protection.
Legal interpretation considers:
Patent Landscape in South Africa

FAQs
1. How does South Africa's patent law impact the enforceability of Patent ZA200508313?
South African patent law emphasizes novelty, inventive step, and industrial applicability, requiring that claims be specific yet sufficiently broad. Proper patent prosecution and clear claim language facilitate enforcement and reduce invalidation risks.
2. Can a generic manufacturer develop similar drugs without infringing this patent?
Yes, if they design around the specific claims—such as altering chemical structures or formulations that fall outside the patent’s scope—they can potentially avoid infringement. Detailed claim analysis is essential.
3. What is the typical term of pharmaceutical patents in South Africa, and when might expiry occur?
Standard patent term is 20 years from the filing date. Given the filing date of 2005, the patent likely expires around 2025. Extensions or supplementary protections could modify this timeline.
4. How does the patent landscape influence R&D investments in South Africa?
A robust patent landscape offers clarity on freedom-to-operate and potential licensing opportunities. Clear patent protection encourages innovation and strategic partnerships in the pharmaceutical sector.
5. Are there opportunities for patent challenges or oppositions post-grant in South Africa?
