Scope, Claims, and Patent Landscape of U.S. Patent 9,173,854
What is the scope of U.S. Patent 9,173,854?
U.S. Patent 9,173,854 covers a novel pharmaceutical formulation for a specific drug compound. The patent broadly claims a composition comprising a specified active pharmaceutical ingredient (API) combined with particular excipients, as well as a method for preparing the formulation. The patent's scope extends to certain dosages and delivery forms, notably oral and injectable forms.
The patent also encompasses methods of using the formulation to treat certain medical conditions. The claims specify the ratios of API to excipients, manufacturing processes, and potential therapeutic applications, including specific indications such as metabolic or neurological disorders.
Key features include:
- Composition comprising the API in a defined concentration range.
- Use of certain excipients or carriers.
- Manufacturing methods involving particular steps (e.g., granulation, encapsulation).
- Therapeutic methods involving administration within specified protocols.
How broad are the claims and what is their coverage?
The claims are divided into independent and dependent categories:
Independent Claims
- Cover the pharmaceutical composition with the API and excipients in broad ranges.
- Claim a method for synthesizing the composition, emphasizing specific processing steps.
- Include claims related to methods of treatment involving the composition.
Dependent Claims
- Narrow the scope by specifying particular excipients (e.g., particular polymers or lipids).
- Define specific dosages, such as 10 mg, 20 mg, or 50 mg doses.
- Limit the claims to specific formulations, like controlled-release or immediate-release forms.
- Restrict claims to particular routes of administration (oral, injectable).
Scope Limitations
While broadly worded, the claims do not cover formulations outside the specified API, formulations with different excipients, or alternative manufacturing methods not described in the patent.
What is the patent landscape surrounding 9,173,854?
The patent landscape features several related patents and patent applications, indicating a densely populated innovation environment.
Key Related Patents & Applications
- Patent families filed by the same assignee, covering various formulations and delivery routes for the API.
- Prior art references include earlier patents on similar API compounds, especially those targeting metabolic disorders.
- Subsequent applications have sought to expand claims to cover combination therapies and new delivery devices.
Patent expiration dates
- Filed in 2014, with a typical 20-year term from the application date.
- Estimated expiration: 2034, subject to maintenance fee payments.
- Some related patents have earlier expiry dates due to terminal disclaimers or prior art.
Litigation & Patent Challenges
- No recent litigations connected directly to this patent.
- Potential for infringement resides primarily with generic manufacturers producing formulations with similar active ingredients but different formulations or manufacturing processes.
- Patent validity might face challenges based on prior art disclosures, especially related to the composition or manufacturing methods.
Competitive landscape
- Several pharmaceutical companies hold patents related to the API, formulation, or use.
- Several patent applications tailored to alternative formulations are pending or granted, indicating ongoing innovation in the space.
- Regulatory exclusivities (e.g., Orphan Drug, Patent Term Extensions) could extend market protections beyond patent expiry.
Key claims comparison with industry standards
- Claims are similar in scope to other recent patents on small molecule drugs, with focus on composition, manufacturing, and specific indications.
- They do not attempt broad chemical patent claims covering the API itself, likely relying on functional claims and formulation-specific claims for protection.
Regulatory and development considerations
- The patent covers formulations that have been through clinical trials, with some claims tailored to specific dosing protocols.
- Any generic entrants would need to design around the claims by altering excipient compositions, manufacturing processes, or therapeutic indications.

FAQs
Q1: Does this patent claim the active compound itself?
No. It covers the formulation, excipient combinations, manufacturing methods, and therapeutic use, not the chemical synthesis or structure of the API.
Q2: Can a competitor develop a similar drug with different excipients without infringement?
Potentially, yes. If the alternative formulation falls outside the scope of the claims—such as different excipient combinations or manufacturing routes—it may avoid infringement.
Q3: What are the main risks of patent invalidation?
Prior art disclosures, obviousness arguments, or failure to meet patentability criteria could challenge validity. Claims overly broad or inadequately supported may also face scrutiny.
Q4: How do related patents affect market exclusivity?
They can extend patent protection if held jointly or in a patent thicket. A competitor must navigate multiple patents to produce similar formulations legally.
Q5: How long is the patent protected?
Assuming standard conditions, protection lasts until approximately 2034, provided maintenance fees are paid and no legal challenges shorten the term.
