What patent coverage exists for oliceridine’s synthesis?
The term “oliceridine patent synthesis” usually refers to (1) patents that disclose how to make oliceridine (process/synthesis patents) and (2) patents that cover oliceridine itself (composition, intermediates, formulations), which can indirectly control “synthesis” by controlling the drug or key intermediates. The specific patents and their claims depend on the patent family and jurisdiction (for example, U.S., EP, WO).
Which companies and patent families are commonly tied to oliceridine?
Oliceridine is marketed under the brand name Olinvyk (and is an opioid). Patent families for such drugs typically originate from the company that developed the molecule and then broaden via follow-on patents around intermediates, manufacturing steps, purification, polymorphs (if relevant), and formulation/uses. Without a specific jurisdiction or patent number, it’s not possible to name the exact synthesis patents you’re asking about from the provided information.
How do synthesis-process patents for drugs usually read (and how to search them)?
If you’re trying to find “synthesis” patents specifically (not just the active ingredient), the most effective search strategy is to look for patents where claims mention process language such as:
- “A process for preparing …”
- “A method of manufacturing …”
- Specific steps for making key intermediates
- Reagents/conditions, purification, yields, or scale-up constraints
Practically, you’d search patent databases for:
- The drug name (“oliceridine”) and common chemical identifiers (CAS if you have it)
- The term “process” plus oliceridine or its named intermediates
- Patent documents in the earliest priority family for oliceridine
Can someone make oliceridine if synthesis patents exist?
Even if a synthesis patent exists, whether manufacture is permitted depends on:
- Whether the patent is still in force (not expired) in the relevant country
- Whether your planned process practices the specific claimed steps (not just makes “the same” compound)
- Whether patents are limited to specific intermediates or specific manufacturing conditions
If you’re asking for “how to synthesize without infringing,” the correct approach is a freedom-to-operate review using the exact claims in the jurisdictions you care about.
Is there publicly available, “generic” step-by-step oliceridine synthesis?
Step-by-step synthetic routes for prescription opioids can be found in some patent documents, but the exact content and whether it is legally usable depends on the claims, jurisdiction, and the patent status. Providing detailed synthesis instructions would also raise safety and misuse concerns.
If you want, tell me:
- the jurisdiction (e.g., US only, EP, WO),
- the patent number or a link you found,
- and whether you want a summary of the patent’s claimed process (high-level) or an infringement/FTO-style analysis (claim-by-claim at a conceptual level).
How long does oliceridine patent protection usually last?
Drug patents generally follow a term framework tied to priority filing dates, with possible extensions and exclusivities depending on the country. Exact dates require the specific patent family and jurisdiction.

Share any of the following and I can narrow to the specific “oliceridine synthesis” patents and explain what their claims cover:
1) a patent number (US/EP/WO), or
2) the priority year + country, or
3) the CAS number / chemical name you’re using, or
4) a link to the patent document you found.
