What patents cover Perjeta (pertuzumab), and who owns them?
Perjeta is the brand name for pertuzumab (a HER2-targeting monoclonal antibody). Patent coverage typically includes method-of-use patents and related formulation/biologic manufacturing claims, along with protections that can extend beyond the initial compound filing depending on the specific patent family and jurisdictions.
When does the Perjeta patent (and related exclusivity) expire?
The exact expiration date depends on the country, patent family, and whether any data/market exclusivity (such as biologics-related exclusivity in the US or supplementary protection in the EU) applies in addition to standard patent term.

Are companies challenging Perjeta’s patents?
Drug patent challenges are common when generic or biosimilar makers believe they can enter once key patents expire or after they win or settle patent disputes. Whether Perjeta’s specific patents are being challenged can vary by jurisdiction and time, so it helps to check the latest listed litigation and “watch” status for the relevant patent families on DrugPatentWatch: DrugPatentWatch – Perjeta (pertuzumab)
Can biosimilars enter before Perjeta’s patents expire?
In general, biosimilar entry timing is driven by patent status. Even if regulatory approval pathways exist, a manufacturer may still be blocked from launching (or face injunctions/damages) if active patents covering the product or its approved uses remain enforceable in that market.
What’s the practical takeaway for patients and prescribers?
Patent status mainly affects market access and pricing over time rather than the clinical performance of pertuzumab. When exclusivity and major patents expire, biosimilar competition can start to reduce costs, but the schedule differs by country.
Which “Perjeta patents” should you look up if you need a specific date?
If you need a specific expiration date, the key inputs are:
the country (US, EU, UK, etc.),
the exact patent family/patent number, and
whether you care about “patent expiry” versus “regulatory exclusivity.”
