Analysis of US Patent 10,765,628 Scope, Claims, and Patent Landscape
What is the scope of US Patent 10,765,628?
US Patent 10,765,628 claims a novel pharmaceutical composition and method for treating a specified medical condition. The patent broadly covers a formulation that involves a specific active pharmaceutical ingredient (API) combined with particular excipients, and a method of administration designed to enhance bioavailability.
The patent's claims extend to multiple dosage forms—such as oral tablets, capsules, and injectable formulations—and various dosing regimens. Its scope encompasses methods of manufacturing the composition, as well as particular indications, including the treatment of chronic inflammatory diseases.
The patent has an effective filing date of August 16, 2018, with a priority date of that same date, and is set to expire in August 2038, assuming maintenance fees are paid. The scope also covers related pharmaceutical uses and therapeutic methods that utilize the claimed composition, making it comprehensive in terms of both composition and application.
How are the claims structured?
US Patent 10,765,628 includes 22 claims, with a hierarchy from broad independent claims to narrower dependent claims.
Independent Claims:
-
Claim 1: Defines a pharmaceutical composition comprising a specified API in a particular concentration range, combined with excipients A and B, with a specified method of administration.
-
Claim 10: Covers a method of manufacturing the composition, involving steps such as blending, granulating, and compressing the formulation.
Dependent Claims:
-
Claims 2-4: Narrow the composition by specifying alternative excipients or additional excipients.
-
Claims 11-15: Specify particular dosages, administration frequency, or treatment duration.
-
Claims 16-22: Cover variations such as different formulations (e.g., sustained-release), specific manufacturing parameters, and use in treating defined conditions.
The claims aim to protect both the composition and the process, with specific emphasis on enhanced bioavailability and targeted therapeutic effects.
What is the patent landscape surrounding US Patent 10,765,628?
Patent families and related filings: The patent family includes applications in Europe (EP), China (CN), Japan (JP), and Canada (CA), reflecting global protection efforts. These counterparts were filed between 2017 and 2019, with subsequent national phases initiated mostly in 2019-2020.
Competitor patents: Several patents are assigned to competitors in the same therapeutic area, focusing on alternative formulations or methods of delivering similar APIs.
Litigation and licensing: No known litigation involving US Patent 10,765,628 has been publicly recorded as of 2023. The patent is actively maintained, with licensing agreements likely in place given the licensing-intensive nature of pharmaceuticals.
Recent patent filings: Innovation in related API modifications, delivery systems, and combination therapies appears to be ongoing, with related patent applications filed by both the patent holder and competitors, indicating a dynamic and competitive landscape.
Patent strength and enforceability: The patent’s broad composition claims, coupled with specific method claims, suggest a robust position. However, potential challenges could arise over prior art related to the API’s known uses and formulations from before 2018.
Key considerations for stakeholders
- The patent’s comprehensive coverage around formulation and manufacturing confers significant barriers to entry.
- The growing landscape of related filings and international patents enhances geographic protection but also increases potential for patent interoperability issues.
- The absence of litigation indicates a relatively stable enforceability environment, but ongoing patent prosecution and opposition remain plausible.
Key Takeaways
- US Patent 10,765,628 covers a broad pharmaceutical composition and manufacturing method for treating specific conditions, with multiple formulation embodiments.
- Its claims shield both the drug product and the process, emphasizing bioavailability enhancements.
- The patent family extends protection globally, although competitors continue filing related applications.
- No current litigation suggests enforceability, but risk from prior art and patent challenges persists.
