Pulse Analysis

The Zaha Hadid dispute highlighted a growing tension in intellectual‑property licensing: whether parties can end an agreement that lacks a fixed term without breaching contractual obligations. The High Court’s earlier decision forced practitioners to interpret termination rights through a narrow lens of express‑term construction, creating uncertainty for businesses that rely on flexible, long‑running licences. By revisiting the contract’s language, the Court of Appeal shifted focus to the substantive intent of the parties, recognizing an indefinite duration as a trigger for the well‑established reasonable‑notice doctrine.

Sir Colin Birss C’s judgment draws directly on the Martin Baker v Canadian Flight Equipment precedent, which sets out the criteria for reasonable‑notice termination in contracts of indefinite length. The appellate court concluded that the Zaha Hadid licence, though not expressly perpetual, was designed to operate indefinitely, thereby falling squarely within the Martin Baker framework. This approach sidesteps the artificial split between express‑term construction and implied‑term implication, offering a more pragmatic and commercially sensible analysis that aligns with broader contract law principles.

For IP lawyers and business executives, the decision sends a clear signal: future licence agreements should expressly define duration or incorporate termination clauses that reflect the parties’ expectations. The clarification reduces litigation risk and encourages more precise drafting, which can streamline negotiations and protect brand assets. Moreover, the ruling may influence upcoming trademark‑licensing disputes, as courts now have a reinforced benchmark for assessing termination rights, ultimately fostering greater stability in the IP market.
