All over 250 CAD

>Novo Nordisk’s lawyers requested a refund for the paid 2017 maintenance fee of $250 Canadian dollars ($185) because the company wanted more time to see if it wanted to pay it, according to letters included in the documents.

>Two years later, the office sent a letter saying the fee, which now included a late charge bringing the total to CA$450, was not received by the prescribed due date.

>Novo Nordisk had a one-year grace period to pay, but never did, and so its patent lapsed in Canada. It lapsed in 2020 when the fee was not received, but it doesn’t expire until January.

LOL, that must be one of the biggest fuck ups in pharmaceutical industry.
