Beecham Group PLC and Another v Triomed (Pty) Limited

Beecham Group PLC marketed a pharmaceutical antibiotic drug called Augmentin (containing amoxycillin and potassium clavulanate) in tablet form. The tablets had a distinctive bi-convex, oval shape. After Beecham's patent for the composition expired, it obtained trade mark registration (no 95/13154) for the shape and curvature configuration of the tablet on 3 October 1995. The mark was registered for "antibiotics" in class 5 without limitation to color or size. Triomed (Pty) Limited imported and sold a pharmaceutical with the same composition under the name Augmaxcil. Triomed's tablets had the same shape and color (white) as Augmentin tablets, though Augmentin tablets were embossed with the name while Augmaxcil tablets were blank. Triomed applied to the Transvaal Provincial Division for rectification of the Trade Marks register by expungement of the shape mark. Beecham counter-claimed for trade mark relief regarding both the shape mark and its word mark "Augmentin". Smit J upheld Triomed's application and dismissed Beecham's counter-application (except regarding the word mark). Beecham appealed to the Supreme Court of Appeal.

• Whether the shape mark constituted a trade mark within the meaning of s 10(1) of the Trade Marks Act 194 of 1993
• Whether the mark was capable of distinguishing within the meaning of s 9 and s 10(2)(a) of the Act
• Whether the mark consisted exclusively of a shape necessary to obtain a specific technical result under s 10(5)
• Whether registration of the mark was likely to limit the development of any art or industry under s 10(11)
• Whether functional shapes can be protected as trade marks
• The proper interpretation of South African trade mark provisions based on the EU First Council Directive

The appeal was dismissed with costs, including costs of two counsel. The expungement of trade mark registration no 95/13154 was confirmed.

A functional shape cannot be registered or maintained as a trade mark if: (1) it is not inherently capable of distinguishing the goods of one trader from those of another (i.e., does not function as a "badge of origin"), and has not acquired such capability through use; (2) it consists exclusively of a shape necessary to obtain a specific technical result, where the essential functional features are attributable only to that technical result (s 10(5)); and (3) its registration would limit the development of any art or industry (s 10(11)). The fact that alternative shapes could achieve the same technical result does not overcome the prohibition in s 10(5). Extensive use and market recognition are insufficient to confer distinctive character if the shape does not actually distinguish goods by their commercial origin. The inquiry is whether the mark guarantees to consumers that goods bearing it originated from a single undertaking responsible for their quality.

Harms JA made several noteworthy observations: (1) There is an increasing tendency to seek intellectual property protection in fields not designed or intended to cover a particular area, illustrating tension between competition principles and intellectual property rights; (2) Different intellectual property rights have different requirements and durations, and each should be kept "firmly within its legitimate bounds"; (3) The aphorism "what is worth copying is prima facie worth protecting" from copyright law cannot simply be transplanted to trade mark law as it would negate foundations of the free market system; (4) Whether the absolute rule against passing-off protection for functional shapes still makes sense given changes to trade mark law is a "moot question" that may merit future development; (5) The question whether a mark can only fail to be a trade mark if someone does not use it as such (the converse of the subjective test) was left for another day due to insufficient argument; (6) While South African courts are not bound by European jurisprudence, the Trade Marks Act must be interpreted in light of South African law and circumstances, and local policy considerations may differ from those in Europe; (7) The protection of functional designs has evolved across multiple intellectual property regimes (patents, copyright, designs, trade marks) creating overlapping areas of protection.

This case is significant in South African trade mark law for establishing important principles regarding the registrability of functional shapes as trade marks. It clarified that: (1) Functional shapes are not automatically excluded from trade mark protection, but must be assessed on their facts; (2) The "badge of origin" function remains central to trade mark law—a shape must actually distinguish the goods of one trader from those of another, not just one product from other products; (3) Extensive use and market recognition do not automatically confer distinctive character on a functional shape; (4) Shapes necessary to achieve technical results (ease of swallowing, coating, structural integrity) cannot be monopolized through trade mark registration; (5) The fact that alternative shapes could achieve the same technical result does not save a functional shape from invalidation under s 10(5); (6) Trade mark law should not be used to extend monopoly protection beyond the life of patents or to restrict competition in functional features; (7) South African courts will have regard to European jurisprudence (particularly ECJ decisions interpreting the EU Trade Mark Directive) given that South African legislation is based on the EU Directive, though such decisions are persuasive rather than binding. The case represents an important limitation on attempts to use trade mark law to protect functional features and maintain market exclusivity after patent expiry in the pharmaceutical industry.
