The High Court of Australia’s recent decision Calidad Pty Ltd v Seiko Epson Corporation  HCA 41 (Calidad) has more closely aligned Australian patent law with its U.S. and European counterparts. Key takeaways from this decision are:
- the ‘doctrine of exhaustion of rights’ has replaced the ‘implied licence doctrine’;
- a patent owner’s exclusive rights are extinguished by the first sale of the patented goods;
- innovators have greater scope to reuse products without risking patent infringement; and
- patentees seeking greater control over post-sale use should do so through contract law.
