Facts

The dispute

Seiko Epson sold printer cartridges embodying patented inventions. After the cartridges were used, a third party collected them, modified them so they could be refilled and reused, and Calidad imported and sold the modified cartridges in Australia. Seiko alleged that the modifications and resale infringed its patent rights because the cartridges had effectively been remade.

Issue

The legal question

The Court had to decide whether the modifications amounted to impermissibly making a new patented product, and whether Australian law should use the exhaustion doctrine instead of the older implied licence approach after a patented product is sold.

Outcome

Decision

The High Court allowed Calidad's appeal. A majority accepted the exhaustion doctrine and held that the relevant modifications did not amount to making a new product; they were modifications of products that had already been sold.

Practical impact

Commercial note

A patent owner may not control every downstream use after first sale. Businesses refurbishing, repairing, importing or reselling patented products need to understand the exhaustion line.

Patent rights can be exhausted after first sale, but modifications still need legal analysis.
Repair and refurbishment businesses should check patent and product-safety risk together.
Importers need to understand overseas acquisition rights and Australian patent rights.

Practical read

Calidad is a refurbishment case with real commercial bite. A business model was built around collecting used printer cartridges, modifying them for reuse and importing them for resale. Seiko said that went beyond ordinary ownership rights and infringed patent rights.

The High Court accepted that patent rights in a product can be exhausted on first sale, but that does not make every modification safe. The practical question for refurbishers, importers and circular-economy businesses is whether they are prolonging the life of an existing product or making a new embodiment of the patented invention.
