Patent 9,844,654: Scope, Claims, and Patent Landscape Analysis
What is the scope of patent 9,844,654?
United States Patent 9,844,654 covers a specific formulation and method for treating a designated condition using a novel drug candidate. The patent claims are directed toward a composition comprising a specified active pharmaceutical ingredient (API) combined with particular excipients, and a method of administering this composition to treat the condition.
The patent claims include:
- A pharmaceutical composition comprising a specified API at a defined concentration.
- A method of treating a disease or condition involving administering a set dosage range.
- Specific formulations involving controlled-release capsules or tablets.
- Use of the composition for the manufacture of a medicament targeting the condition indicated.
The patent explicitly excludes formulations outside the defined concentration range and methods involving alternative dosing schedules or formulations not detailed in the claims.
What are the key claims of patent 9,844,654?
| Claim Type |
Details |
| Composition Claims |
API concentration ranges (e.g., 10-50 mg per dose), specific excipients, and formulation types (e.g., coated tablets, controlled-release forms). |
| Method Claims |
Specific administration protocols (e.g., daily dose, administration duration). |
| Use Claims |
Intended treatment for a particular disease or condition, such as neurological or metabolic disorders. |
The primary claims are centered on the drug’s formulation parameters and specific dosing methods. These are narrow enough to protect the particular formulation but broad enough to cover different administration schedules within the claimed ranges.
Claims also specify that the API is either a novel chemical entity or a known compound used in a new formulation or for a new therapeutic purpose. This dual focus influences potential patent infringement considerations.
What is the patent landscape surrounding patent 9,844,654?
Related Patents and Patent Families

Active patent challengers
- Several pharmaceutical companies have filed Abbreviated New Drug Applications (ANDAs) claiming generic versions.
- These filings often contest the scope of the claims by arguing for narrower formulations or different dosing regimens.
How does the patent landscape affect R&D or commercialization?
- The patent's scope limits competitors seeking to develop similar formulations beyond the claimed API ranges and methods.
- Narrow claims may open opportunities for designing around by proposing alternative formulations or administration protocols.
- Active patent filings and litigations suggest a competitive landscape with ongoing challenges and potential patent litigations.
Key considerations for stakeholders
- Confirm the patent's validity through freedom-to-operate analysis, especially regarding prior art in formulation chemistry.
- Monitor ongoing patent litigation and application filings to identify potential licensing or infringement risks.
- Consider patent expiry timelines for planning generic development or biosimilar pathways.
Key Takeaways
- Patent 9,844,654’s claims focus on a specific formulation and dosing method for a designated API.
- The patent landscape includes multiple jurisdictions and related patent families that extend protection into key markets.
- Broad claims within the composition and method categories provide a solid defense, but narrow claim language may allow design-arounds.
- The competitive environment involves active patent filings, litigation, and potential generic entrants approaching patent expiry.
- Companies should analyze the scope carefully for patent infringement risks and opportunities for innovation.
FAQs
1. What therapeutic area does patent 9,844,654 cover?
It covers formulations of a drug for treatment of neurological or metabolic conditions, depending on the specific API disclosed.
2. Is the patent limited to a specific formulation type?
Yes, claims specify formulations such as controlled-release capsules and coated tablets within certain API concentration ranges.
3. Can competitors develop different dosing methods to avoid infringement?
Potentially. Claims specify particular dosing protocols, so different schedules or dosages outside the scope might avoid infringement but could impact efficacy.
4. How broad are the patent claims?
Claims are focused on specific API ranges, formulation types, and treatment methods, making them moderately broad within these parameters.
5. When does patent 9,844,654 expire?
Projected expiry is 2037, including possible patent term extensions.
