Good summary on slashdot / alterslash: https://alterslash.org/#article-23719787 which is short enough, so I'll put it here.

***
Pharmaceutical giant Novo Nordisk forfeited patent protection for semaglutide — the active ingredient in blockbuster diabetes and weight loss drugs Ozempic and Wegovy — in Canada after failing to pay a $450 maintenance fee in 2019. The company had paid maintenance fees through 2018 but requested a refund for the 2017 fee, apparently seeking more time to decide whether to continue protecting the patent.

When the 2019 fee came due at $450 with late penalties, Novo never paid despite having a one-year grace period. Canadian patent authorities confirmed the patent “cannot be revived” once lapsed. The oversight is particularly costly given Canada represents the world’s second-largest semaglutide market, worth billions annually. Generic drugmaker Sandoz plans to launch a competing version in early 2026, while Novo’s U.S. patent protection extends until at least 2032.

Time to start stacking Loonies instead of BTC for some of us 🙂
