When will spp closed in Canada?

As of my last update in October 2023, SPP (Supplementary Protection Period) typically refers to specific protections for pharmaceutical patents, and its closure or expiration would depend on individual patent terms rather than a specific date for all SPPs in Canada. Generally, SPPs last for up to two years beyond the standard patent term, contingent on regulatory approval timelines. For the most accurate and current information, it's best to consult official Canadian Intellectual Property Office resources or legal experts in patent law.
