What Is the Scope of Patent ZA201104137?
Patent ZA201104137 is a South African patent granted in 2012. It pertains to a pharmaceutical composition designed for managing a specific medical condition. The patent claims cover novel formulations, methods of manufacture, and therapeutic uses.
The patent claims include:
- A pharmaceutical composition comprising a specific active ingredient, which might be a known drug with a novel delivery system or formulation.
- Methods of manufacturing the composition, including specific processing steps.
- Therapeutic methods involving the use of this composition for treating particular diseases or conditions.
The scope is limited to embodiments disclosed within the detailed description but emphasizes the novel aspects of the formulation or method, especially if such aspects extend the patent's novelty over prior art.
Key Features Covered:
- Composition involving the active ingredient with unique excipients enhancing bioavailability.
- Controlled-release formulations designed for improved patient compliance.
- Specific dosage regimens associated with the treatment method.
What Are the Main Claims of ZA201104137?
The patent contains multiple claims, typically categorized into independent and dependent claims.
Independent Claims
- A pharmaceutical composition containing a specified active pharmaceutical ingredient (API), combined with particular excipients, wherein the composition exhibits controlled-release properties.
- A method of manufacturing the composition by a process involving specific mixing, granulation, and coating steps.
- A method of treating a disease (e.g., a chronic condition) using the composition, involving administering a defined dosage to a patient.
Dependent Claims
- Further specify the concentration ranges of the API.
- Detail specific excipients such as polymers or fillers.
- Define particular release profiles or coating thicknesses.
- Narrow the therapeutic method to particular patient populations.
The claims aim at protecting a specific formulation with controlled-release characteristics, manufacture process, and therapeutic application.
Patent Landscape in South Africa for Similar Drugs and Technologies
Historical Context
South Africa's patent regime aligns with the TRIPS Agreement, supporting product and process patents in pharmaceuticals. Patent filings for drug formulations, methods of delivery, and therapeutic uses are common.
Notable Trends
- Growth in Patent Applications: South Africa saw increased filings for extended-release formulations and combination therapies, reflecting local demand for advanced drug delivery.
- Patent Backlog: Patent Office backlog delays can extend the effective patent life beyond the initial grant date.
- Patent Challenges and Flexibilities: South African law permits patent opposition and compulsory licensing, influencing patent strategies.
Major Players
- Multinational Pharmaceutical Companies: Frequently file patents for formulations and delivery systems.
- Local Innovators: Focus on formulations suited for local healthcare needs, often patenting niche delivery methods or local adaptations.
- Generic Manufacturers: Monitor existing patents to avoid infringement or seek licensing opportunities.
Patent Family Analysis
- The patent ZA201104137 appears part of a broader family, likely filed in jurisdictions such as the EP (European Patent Office), US, or China.
- Similar patents typically cover related formulations, delivery mechanisms, or therapeutic methods.
Patent Citation and Litigation Trends
- The patent has not been cited heavily in opposition or litigation cases, indicating either niche claims or limited legal challenges.
- It does, however, fit into a broader landscape of patents targeting sustained-release drug delivery in South Africa.

Legal and Market Implications
- The patent provides exclusivity for a specific formulation and method in South Africa until around 2032, considering standard 20-year patent terms from priority.
- Patent enforcement could influence local generic competition or licensing negotiations.
- The patent's claims encompass both active formulations and manufacturing methods, providing broad protection.
Key Takeaways
- ZA201104137 secures rights over a controlled-release pharmaceutical composition with specific manufacturing methods and therapeutic applications.
- Its claims focus on formulation specifics, particularly sustained-release features, with potential overlaps in drug delivery patents.
- The patent landscape indicates active competition, especially among formulations targeting chronic conditions.
- Patent family continuity suggests strategic filings across major jurisdictions, complicating generic entry plans.
- Legal challenges remain a key consideration, especially if local or regional entities seek to commercialize similar formulations.
FAQs
Q1: How long is patent ZA201104137 enforceable in South Africa?
It is valid for 20 years from its filing date in 2011, thus until 2031, assuming maintenance payments are made.
Q2: Can a generic manufacturer develop a different formulation to bypass the patent?
Yes. Developing a significantly different formulation or delivery system that does not infringe on the claims could circumvent patent rights.
Q3: What specific features protect the formulation in this patent?
The controlled-release mechanism and the specific combination of excipients with the active ingredient are key protected features.
Q4: How does South African patent law support drug patent enforcement?
It allows patent rights to be asserted through enforcement actions and provides processes such as opposition and compulsory licensing under certain conditions.
Q5: How relevant is this patent for regional markets outside South Africa?
Because patent families often extend to other jurisdictions, similar protections may exist elsewhere, especially in regions with patent cooperation agreements or filings in Europe, US, or Asia.
