In 2019, pharmaceutical giant Novo Nordisk made a stunning administrative error that would have profound financial consequences. The company failed to pay a $450 maintenance fee for its Canadian patent on semaglutide—the active ingredient in its blockbuster drugs Ozempic and Wegovy. This seemingly minor oversight led to the patent's permanent lapse, forfeiting valuable intellectual property protection in Canada.
The timing of this mistake was particularly significant. Ozempic had become Canada's top-selling drug by 2024, with annual sales reaching approximately $2.5 billion. The loss of patent protection meant that generic manufacturers could now prepare to enter the Canadian market once data exclusivity expires in January 2026.
Novo Nordisk has publicly characterized this development as a deliberate strategic decision rather than an error. Company representatives have emphasized that their intellectual property strategies are carefully considered at a global level. However, industry analysts have questioned this narrative, noting that the potential loss of billions in revenue seems inconsistent with strategic planning.
The company maintains that its patent portfolio remains strong globally and that the Canadian market represents only a small portion of its overall business. Nevertheless, the incident has raised questions about internal processes and oversight at one of the world's most valuable pharmaceutical companies.
The consequences of this patent lapse are already materializing. Companies like Hims & Hers Health have announced plans to offer generic semaglutide in Canada starting in 2026. This development is expected to trigger substantial price reductions for semaglutide-based treatments, potentially making these medications more accessible to Canadian patients who previously faced high costs.
The timing coincides with broader market pressures on Novo Nordisk. Recent developments include:
The Novo Nordisk case highlights the critical importance of patent maintenance in the pharmaceutical industry, where intellectual property protection can mean the difference between market dominance and generic competition. The incident serves as a cautionary tale for other pharmaceutical companies about the potential consequences of administrative oversights in global patent management.
While Novo Nordisk continues to enjoy strong patent protection for semaglutide in other major markets, the Canadian situation demonstrates how quickly market dynamics can shift when patent protection is lost. The company now faces the challenge of maintaining its market position in Canada against generic competition while continuing to innovate and protect its intellectual property globally.
The story of Novo Nordisk's Canadian patent lapse underscores the delicate balance pharmaceutical companies must maintain between strategic patent management, market competition, and patient access to essential medications.
