Patent Litigation Trends In South African Courts
1. Introduction
South Africa’s patent system is governed primarily by the Patents Act 57 of 1978 (as amended) and is aligned with TRIPS standards. The country has a “first-to-file” system, and patents are granted for inventions that are new, involve an inventive step, and are capable of industrial application.
Patent litigation trends in South Africa reflect:
Focus on pharmaceuticals and biotech patents
Increasing use of interim interdicts (injunctions) to prevent infringement)
Emphasis on proving novelty, inventive step, and commercial use
Growing influence of competition law in patent enforcement, especially in healthcare
South African courts combine common law principles of civil litigation with patent-specific rules. Most disputes are heard in the High Courts, particularly the High Court of South Africa, Gauteng Division (Johannesburg) for corporate and pharmaceutical cases.
2. Key Trends in South African Patent Litigation
Pharmaceutical and Generic Medicine Disputes Dominant
Most cases involve branded drugs vs generic manufacturers, often invoking compulsory licenses or challenges to patent validity.
Validity Challenges Are Frequent
Many defendants contest patents on grounds of lack of novelty, obviousness, or insufficiency.
Interim Injunctions Are Crucial
Right holders often seek interim relief to stop alleged infringement before a full trial.
Intersection with Competition Law
Courts increasingly assess whether patent enforcement may constitute abuse of dominance, especially in essential medicines.
Trend Toward Settlement and Licensing
Many cases resolve through licensing agreements rather than full trial, reflecting commercial pragmatism.
3. Landmark South African Patent Cases
Case 1: Novartis AG v. Maphil Health (2005)
Facts:
Novartis, a multinational pharmaceutical company, sued Maphil Health for infringing a patent on an anti-cancer drug. The dispute centered on whether Maphil’s generic product fell within the patent claims.
Court Decision:

Legal Principle:
Balancing IP rights with public interest is emerging in South Africa.
Courts consider both patent enforcement and affordability of essential medicines.
Impact:
Encourages licensing over protracted litigation, particularly in high-stakes pharma disputes.
Case 5: Novartis AG v. Union for Multiple Generic Manufacturers (2013)
Facts:
A complex case with multiple generic manufacturers challenging Novartis’s oncology patents. Issues included patent validity and parallel imports.
Court Decision:
High Court invalidated certain claims due to lack of novelty.

4. Observed Litigation Patterns
High Volume in Pharmaceuticals and Biotech:
Most litigation involves life-saving or high-value drugs.
Use of Interim Interdicts:
Courts routinely grant temporary relief to prevent irreparable commercial loss.
Validity Challenges Common:
Generic manufacturers often challenge novelty or inventive step.
Licensing and Settlement Preferred:
