TAPINAROF (TAPINAROF) · · 12 active US patents · 0 expired
Where TAPINAROF sits in the generic timeline
Long-dated protection: earliest active US patent for TAPINAROF extends to 2036 (~10 years out). Generic competition is at least 4 years away. Lifecycle moves (new formulations, label extensions, combination filings) typically execute 18-36 months ahead of cliff.
Under US Hatch-Waxman, a generic enters via an ANDA (Abbreviated New Drug Application) and may file with one of four Paragraph IV certifications attacking the brand's listed patents. If the brand sues within 45 days, a 30-month FDA approval stay is triggered. First Para IV filer typically gets 180-day market exclusivity.
