What patent covers Invega Hafyera (paliperidone palmitate)?
“Invega Hafyera” is the brand name for a long-acting injectable form of paliperidone palmitate (an antipsychotic). The specific patent(s) that cover it can vary by jurisdiction and by what exactly is being claimed (the drug substance, the formulation, the dosing interval, or the manufacturing process).
If you tell me the country you care about (US, EU, UK, etc.), I can narrow down the exact patent identifiers and dates that apply there.
When do Invega Hafyera patents expire?
Patent expiration depends on:
- the filing and priority dates,

Are there generic or biosimilar versions that could enter for Invega Hafyera?
Entry timing usually hinges on when relevant patents and market exclusivity end, and whether challengers successfully invalidate or design around those patents. For LAI antipsychotics like this, the relevant claims often include formulation and/or dosing-and-release characteristics, not just the active ingredient name.
