Who holds the oliceridine synthesis patent, and what exactly does it cover?
“Oliceridine” is an opioid analgesic (marketed as Olinvyk). Information provided here does not include any specific patent numbers, assignees, or claim language for “oliceridine synthesis.” To answer accurately, I need at least one of the following: a patent number, a link to a record (Google Patents, USPTO, Espacenet), or the company/assignee name you’re looking at.
If you share a patent ID (e.g., US20xx/xxxxx or a WO number) or a record link, I can summarize what the synthesis patent claims (e.g., specific intermediates, reaction steps, catalysts/solvents, purification processes, or polymorph/crystal form details), and explain how it relates to producing oliceridine.
What claims typically appear in an opioid “synthesis” patent like oliceridine?
Synthesis-focused pharmaceutical patents often claim one or more of the following, which you can check directly in the claim section of the patent record you have:
- Specific chemical routes to key intermediates used to assemble the oliceridine scaffold.
- Reaction conditions for a step (reagents, catalysts, temperature/pressure ranges, solvent systems, times).
- Purification or isolation methods (workups, crystallization conditions, salt formation).
- Process optimizations that improve yield, reduce impurities, or enable scale-up.
A “process” patent may be broader (covering a whole route) or narrower (covering only one step or one intermediate).
Is there more than one patent covering oliceridine manufacturing?
Usually, yes. Even when people refer to “the oliceridine synthesis patent,” there can be multiple overlapping patents that cover:
- The active pharmaceutical ingredient (API) synthesis route(s).
- Intermediate compounds.
- Impurity control or specific impurity profiles.
- Solid-state forms (polymorphs, hydrates) and how they’re produced.
- Formulation or manufacturing process for the finished drug product.
Because “synthesis” can span multiple domains, it matters which specific patent you mean.
How long would an oliceridine synthesis patent be in force?
Patent term depends on jurisdiction and on the filing date and any adjustments. In general, many pharmaceutical patents are expected to run about 20 years from the earliest non-provisional filing date, but practical expiration can be affected by:
- Continuation/continuing application strategy.
- Patent term adjustments or extensions (more common in some jurisdictions for specific circumstances).
- Expiration of related patents that are often litigated together.
To compute or estimate the actual end date for the synthesis patent you mean, I need the patent record (earliest priority date and jurisdiction).
Are generic or contract manufacturers likely blocked by “synthesis” patents?
If the synthesis patent claims a specific manufacturing process, a company making oliceridine (or an equivalent) could be blocked if it performs the claimed steps as written. However, companies may try to design around by:
- Using a different synthetic route that avoids a claimed step/intermediate.
- Changing conditions so they fall outside claim ranges.
- Producing a different salt or solid-state form (if those forms are claimed).
Whether a design-around works depends on claim scope and how it’s interpreted.
How can you find the right “oliceridine synthesis” patent record?
If you don’t already have a patent number, tell me:
- The country/office you care about (US, EP, WO).
- The assignee/company you suspect (e.g., the drug’s original developer or a manufacturing/chemistry assignee).
- Any fragment of the patent title or publication number.
With that, I can help you identify the most relevant patents and then summarize them—claims, scope, and likely “synthesis” coverage.

What I need from you to proceed
Paste either:
1) a patent link (Google Patents/USPTO/Espacenet), or
2) the patent publication number (e.g., US20xx/xxxxxx or WO20xx/xxxxxx), or
3) the assignee name + jurisdiction.
Once I have that, I’ll summarize the “oliceridine synthesis patent” precisely (what it claims, how it’s used, and what would be needed to design around it).
