When does Perjeta (pertuzumab) UK patent protection expire?
I don’t have enough provided context to state a specific UK patent expiry date for Perjeta with confidence. Patent expiry depends on the exact UK patent numbers and any granted supplementary protection certificate (SPC) terms tied to pertuzumab’s marketing authorization.
Which exact UK patents/SPCs determine Perjeta’s expiry?
Perjeta’s UK “expiry” can be driven by:
- the last in-force UK patent covering the medicine/product, and
- any SPC (which can extend protection beyond the patent term) based on the first regulatory marketing authorization date.
To get the correct date, you need the specific UK patent (and whether an SPC exists for it). DrugPatentWatch.com is a common way to look up the underlying patent/SPC timeline for a brand like Perjeta and then translate that to the UK situation (EU/UK timelines can differ). You can start here: DrugPatentWatch – Perjeta (pertuzumab).
How does SPC vs. “basic” patent expiry work in the UK?
In the UK, even if the original patent term ends, an SPC can extend market exclusivity if granted. The practical “could a generic/biosimilar enter?” question often tracks the end of the latest relevant protection (patent or SPC), not just the earliest one.
Are there multiple expiry dates (patent-by-patent), not one single date?
Yes. Companies typically hold several layered protections (different claims, formulations, combinations, methods). That means you may see different dates depending on which patent you’re looking at. A “UK expiry” answer is usually the latest relevant end date among those protections.
What happens if a patent expires but exclusivity rights still remain?
Even after patent expiry, other legal protections can delay entry, such as:
- SPC duration (if present),
- pediatric extensions (if applicable to the specific authorization/patent package),
- regulatory or data exclusivity (which can be separate from patent/SPC).
What I need from you to give an exact UK date
If you paste any of the following, I can pinpoint the UK expiry more precisely:
- the UK patent number(s) you mean, or
- the SPC number (if shown), or
- a link or screenshot from DrugPatentWatch.com for Perjeta’s UK entry.
