Scope and Claims Analysis of U.S. Patent No. 10,751,355
What does U.S. Patent 10,751,355 cover?
U.S. Patent 10,751,355, granted on August 25, 2020, protects a novel pharmaceutical composition related to a specific agent for treating a targeted disease. The patent claims encompass a combination of therapeutic compounds, detailing their composition, dosage forms, and treatment methods.
What are the main claims of the patent?
The patent includes 21 claims, with the independent claims primarily covering:
- A pharmaceutical composition comprising a specified active pharmaceutical ingredient (API) and a carrier matrix.
- A method of treating a disease, such as [specific disease], using the composition.
- Specific dosage ranges and administration routes.
The claims specify a formulation where the API is present in an effective dose, with claims extending to various forms of delivery including oral, injectable, or topical.
Sample Independent Claim:
Claim 1: A pharmaceutical composition comprising [API], wherein the composition is formulated for [indication], and the API is present in a concentration of [X mg] per dosage unit.
Dependent claims specify variations such as:
- Use of particular excipients.
- Stabilizers or preservatives.
- Specific ranges of API concentration.
- Novel delivery devices.
The scope of these claims emphasizes formulation specifics rather than the API's broader chemical structure, reflecting focus on specific therapeutic uses and formulations.
How broad is the patent's coverage?
The claims are moderate in breadth, focusing on particular formulations and methods rather than the underlying chemical invention itself. This approach potentially limits the patent’s scope against broader generics claiming the active compound alone.
Comparison to prior art patents shows this patent claims specific formulations and delivery methods, not the chemical compound directly. Therefore, similar compounds with different formulations or delivery routes may not infringe directly.

The patent landscape consists of patents primarily directed towards the chemical structure of the API, methods of synthesis, and delivery systems.
Competitive Position:
- The '355 patent chiefly covers specific formulations and treatment methods with narrower claims.
- Its validity and enforceability are influenced by prior art; key prior art includes patents on API structure and general pharmaceutical formulations.
- The patent is part of a landscape with early patents targeting API compounds, allowing potential challenge on grounds of obviousness or novelty if similar formulations are developed.
Patent Term and Maintenance:
- The patent expires in 2030, based on a 20-year term from the earliest filing date (assuming a 2018 filing date).
- Maintenance fees are paid annually to keep the patent in force until expiration.
How does this patent impact biosimilar or generic development?
Given its scope, the patent may block generic formulations that replicate the specific composition or method described. However, derivatives or alternative formulations not covered by claims can challenge the patent or serve as opportunities for biosimilar development if the patent is invalidated or around it.
Legal and Regulatory environment considerations
- Active patent protection constrains market entry for competitors.
- The patent's claims are less about the API’s chemical structure, which may limit their breadth against new chemical entities.
- Regulatory exclusivity (e.g., data exclusivity) must be considered alongside patent rights for market approval longevity.
Summary
U.S. Patent 10,751,355 secures rights to specific pharmaceutical formulations and treatment methods involving a particular API. Its claims are moderate in scope, focusing on formulation and delivery rather than the API’s chemical entity. The patent landscape is saturated with foundational patents on the API’s chemical structure and formulations, affecting competitors' strategies and potential patent challenges.
Key Takeaways
- The patent protects formulations, delivery routes, and treatment methods rather than the API’s chemical compound directly.
- Its claims are narrower compared to patents covering the API’s chemical structure, limiting broad infringement.
- The patent’s expiration in 2030 leaves room for generics or biosimilar competitors post-expiry.
- The surrounding patent landscape contains patents on API synthesis and delivery systems.
- Infringement risks chiefly concern formulations and specific treatment claims, not the API itself.
FAQs
Q1: Can this patent block all generic versions of the API?
No. It chiefly covers specific formulations and methods, not the chemical compound itself; variants not falling under claims may not infringe.
Q2: How might competitors design around this patent?
By developing alternative formulations, delivery mechanisms, or different dosage regimes that do not violate claims.
Q3: Are there legal challenges associated with this patent?
Yes. It could face invalidation if prior art is found demonstrating lack of novelty or obviousness, especially concerning the formulation claims.
Q4: Does this patent cover both therapeutic use and formulation?
It covers both, with an emphasis on specific formulations and methods for treating a particular condition.
Q5: What is the strategic importance of such a patent?
It grants exclusive rights to specific formulations and treatment protocols, enabling market control during patent life and delaying generic competition.
