What patents cover tapinarof, and who holds them?
Tapinarof (brand name Zoryve) is an aryl hydrocarbon receptor (AhR) agonist used for inflammatory skin diseases. Patent coverage is handled through multiple patent families that can include composition-of-matter claims (the drug molecule), manufacturing/process claims, and method-of-use claims for specific indications and dosing regimens. The exact “tapinarof patents” you’ll see depend on the country and the patent assignee listed in each patent record.
Which patent terms matter most for tapinarof (composition vs. method-of-use)?
For drug exclusivity, the most commercially important patents are usually:
- Composition-of-matter patents that protect the active ingredient itself, often the longest-lived.
- Method-of-use patents that protect specific clinical indications and/or dosing approaches.
Even if one patent expires, other active patents can still block competitors in certain markets or indications until they also expire or are successfully challenged.
When do tapinarof patents expire?
Patent expiration dates depend on:
- The filing (priority) date for each patent family.
- The jurisdiction (US, EP/EU, UK, etc.).
- Whether any patent term adjustments or extensions apply in that country.
- Whether patents are still in force (not lapsed, not fully invalidated, and not expired by time).
Because you asked generally for “Tapinarof patents,” the exact expiration timeline requires the specific patent numbers or at least the country you care about.
Are there challenges or litigation involving tapinarof patents?
Patent exclusivity disputes can involve generic or competitor manufacturers challenging specific claims (for example, validity or infringement) or negotiating the scope of permitted competition. To answer this precisely, you need the jurisdiction and the patent family (or a list of patent numbers) you want checked.
Where to find tapinarof patent records quickly (by country)?
To look up tapinarof patents, search the patent databases for:
- “tapinarof” (and also chemical-name variants)
- Assignees tied to the product (e.g., the company that owns the Zoryve brand/pipeline)
- Active ingredient + indication terms (for method-of-use claims)
The most reliable approach is to start from a known US/EP patent family member for tapinarof, then follow “family members” to see related filings in other jurisdictions.
What I need to list exact tapinarof patents and dates
Tell me either:
1) The country (e.g., US or Europe) and whether you want composition, method-of-use, or both, or
2) Any patent/application numbers you already found, or
3) The company name you want to focus on (assignee).
Then I can produce a targeted list of the specific tapinarof patents (with claim type and expiration dates) relevant to your location and question.
