What Does the Patent Landscape Look Like for Opioid Analgesics?
Patent Filing Trends
- Peak Patent Activity: 1990s to early 2000s, coinciding with the development of extended-release formulations.
- Decline in New Inventive Patents: Since 2010, patent filings for primary opioid molecules have declined, with focus shifting to formulations and delivery mechanisms (3).
- Emergence of Patents on Abuse-Deterrent Formulations (ADFs):
- Facilitates extended patent protection.
- Example: Purdue’s OxyContin reformulated with abuse-deterrent features in 2010s, yielding patent protections until at least 2025.
