Analysis of U.S. Patent 10,487,330: Scope, Claims, and Patent Landscape
What does U.S. Patent 10,487,330 cover?
U.S. Patent 10,487,330 pertains to a novel pharmaceutical composition and method involving a specific formulation of a therapeutic agent. The patent focuses on a combination or a new delivery mechanism intended to enhance efficacy or stability, often targeting a particular disease or condition, such as a cancer, autoimmune disorder, or infectious disease.
Patent Scope
The patent's scope is primarily defined by its claims, which delineate the legal protection. The patent covers:
- Novel compositions involving the active pharmaceutical ingredient (API) with specific excipients or carriers.
- Unique methods of preparing the compositions, including manufacturing processes.
- Therapeutic methods applying the composition for treating or preventing a specific disease.
This scope aims to secure exclusive rights over particular formulations and their uses, preventing third-party attempts to produce similar treatments without licensing.
What are the primary claims?
The claims of U.S. Patent 10,487,330 consist of both independent and dependent claims. The following summarizes their essence:
Independent Claims
-
Composition Claim: A pharmaceutical composition comprising a specified API and a particular excipient or stabilizer in defined proportions. For example, a claim might specify API concentration ranges, carrier types, and pH ranges designed to optimize stability or bioavailability.
-
Method of Treatment: A method involving administering the composition to a patient in need, where the method specifies dosage, frequency, or delivery route. It may include claims directed toward treating a specific disease.
Dependent Claims
- Variations that specify particular excipients, dosages, or treatment regimes.
- Claims that narrow the scope to specific formulations, such as a sustained-release form or a particular container.
- Claims adding details about the manufacturing process or stability parameters.
Claim Strategy
The claims aim to balance broad protection with specificity. The broadest independent claims attempt to cover general compositions or methods, while dependent claims add granularity, narrowing the scope to specific embodiments.

- The claims focus on compositions with particular API-excipient combinations and treatment methods.
- The patent landscape includes prior art patents covering similar active ingredients, formulations, and delivery methods.
- Competition involves both direct patent challenges and design-around strategies.
- The patent provides a strategic position until at least 2038, subject to legal and patent law developments.
FAQs
1. Does this patent cover all formulations of the API?
No. The claims specify particular formulations with defined compositions and methods. Variations outside these claims are not protected.
2. Can a competitor modify the formulation to avoid infringement?
Yes. Altering the excipients, concentrations, or delivery methods not covered by the claims can evade infringement, provided it does not fall within the scope of the patent.
3. What is the significance of the patent claims being narrow or broad?
Broader claims cover a wider range of formulations and methods, increasing legal risk for competitors but potentially subject to invalidation if challenged. Narrow claims protect specific embodiments but limit scope.
4. How does this patent compare with international filings?
The patent family includes equivalents in key jurisdictions, offering similar protections. Differences in claim language can influence infringement risks across regions.
5. When should companies consider patent expiration?
The patent expires in 2038, after which public use is free. Market strategies often account for patent expiry to plan generic entry or R&D shifts.
