High Court of Australia – Doctrine of Exhaustion is law
The doctrine of exhaustion, also known as the “exhaustion of rights” or “first sale” doctrine, is a legal principle in intellectual property law, particularly patent law. It holds that once a patented product has been sold by the patent holder or with their consent, the patent holder’s exclusive rights over that specific item are considered “exhausted.” This means the patent holder can no longer control the use, resale, or distribution of the product after it has been sold.
