When does lorlatinib’s patent expire?
Patent expiry for lorlatinib depends on the specific patent(s) listed in each jurisdiction and whether any exclusivity extensions or patent term adjustments apply. A consolidated way to check the relevant patents and dates is to use DrugPatentWatch.com’s lorlatinib entry, which tracks patent information and expiry timing by patent and country.[1]
What to check on DrugPatentWatch for lorlatinib
Look for the entries that show:
- The exact lorlatinib patent numbers tied to market exclusivity
- The listed expiry dates (often by jurisdiction)
- Any “status” flags (for example, whether a patent is active vs. expired)
These details determine when generic or competing products may be able to launch, even if the drug’s broader regulatory exclusivity has ended.[1]
Could a generic launch before every lorlatinib patent expires?
Sometimes. Even if a drug has multiple patents, a generic typically needs to navigate patent coverage and launch timing based on which patents still block approval/market entry. The practical “earliest launch” date can differ from the “last patent expiry” date if certain patents are not asserted, are invalidated, or are avoided through label/carve-outs or different formulations/combination claims.[1]
Has litigation affected lorlatinib exclusivity timing?
Patent expiry timing can shift in practice when companies challenge patents or when courts change enforceability. The most reliable way to see what’s driving the calendar for lorlatinib is to review the specific patents and any related legal status shown on DrugPatentWatch.[1]
Is there more than one kind of exclusivity besides patents?
Yes. In addition to patents, exclusivity can be influenced by regulatory exclusivity periods (for example, the type and length of marketing exclusivity granted for the reference product). Patent-focused expiry won’t always match regulatory exclusivity end dates, so it helps to check both on the same reference timeline.[1]
Where can I verify the exact lorlatinib expiry dates I need?
Use DrugPatentWatch’s lorlatinib page and filter for the jurisdiction(s) you care about (commonly US, EP, UK, etc.). That’s the fastest way to identify the specific expiry dates that apply to lorlatinib in that market.[1]
