The Patent Cliff Tracker

For every FDA-approved drug: when does exclusivity expire? When do generics flood in? How have manufacturers serviced it? What does the global picture look like? And is the research field still hot — or has it gone stale?

Patent Cliff Timeline — 2025-2040

Each bar shows when the last listed patent expires for that drug. The red line is "now" — anything left of the line has already lost exclusivity. Anything right of the line is still protected.

9 Drugs Tracked

Click into any drug to see its full profile: patent cliff, NCE exclusivity, DEA schedule, REMS program, NDC manufacturer data, global approval status, and research pipeline.

Where Each Drug Is Approved

Not all drugs are available everywhere. Some are approved in the US but not the EU. Some are women-only. Some aren't approved anywhere despite huge trial counts.

Research Activity Radar

Is the field hot, active, quiet, or dead? Are the "top of the ladder" indications still being improved — or has research stalled?

How We Track the Cliff

NCE Exclusivity (5 Years)

New Chemical Entity exclusivity runs 5 years from FDA approval. No generic can be approved during this window. The first ANDA can be filed after 4 years.

Patent Cliff

When all listed patents expire. Originator files multiple patents: compound, formulation, method-of-use, process. The last expiring patent is the true cliff.

Paragraph IV Challenge

If a generic manufacturer files ANDA with Paragraph IV certification (claims patent is invalid/non-infringing), the 30-month stay begins. First filer gets 180-day exclusivity.

REMS Programs

Risk Evaluation and Mitigation Strategy. Required by FDA for drugs with serious safety risks. iPLEDGE (Accutane) is the most stringent — mandatory pregnancy tests, enrollment for all actors in the chain。

Research Activity Signal

Live counts from ClinicalTrials.gov v2 API. Hot = 15+ recruiting trials. Active = 5-15. Quiet = <5. Dead = 0-2. Paradox = many trials but no FDA approval (investigate why).

Global Regulatory Map

For each drug: which countries approved it, which rejected, which have pending applications. Identifies opportunity markets where the drug has never been filed.
