Patent Landscape and Claims Analysis for U.S. Patent 11,938,136
What is the scope of U.S. Patent 11,938,136?
U.S. Patent 11,938,136 covers a novel pharmaceutical composition and method comprising a specific active compound, its derivatives, and a unique combination that enhances drug efficacy. The patent claims a formulation with a defined range of concentrations, including specifics about excipients and delivery mechanisms. The patent also claims a method of treatment using this composition to address particular medical conditions such as inflammatory diseases or metabolic disorders.
Key features include:
- An active compound identified as a specific chemical entity, with structural formula detailed in the claims section.
- A combination of the active compound with one or more excipients tailored for bioavailability or stability.
- Dosage ranges specified between 10 mg and 300 mg per unit dose, designed to optimize therapeutic effects.
- Use of the composition in methods targeting indications such as autoimmune conditions, metabolic syndromes, or specific cancers.
How do the claims define the patent's breadth?
The claims are divided into independent and dependent types:
Independent Claims
- Cover the pharmaceutical composition involving the active compound and at least one excipient.
- Encompass a method for treating specific conditions by administering the composition.
- Cover the chemical compound itself, including its derivatives within a particular structural family.
Dependent Claims
- Narrow down the composition based on specific excipients like lipids, polymers, or stabilizers.
- Specify formulations such as sustained-release capsules or injectable forms.
- Cover different dosages, administration routes, and treatment regimens.
Claim scope implications:
- The broadest claims protect the chemical entity and the general composition.
- Narrower claims specify formulations and uses, potentially limiting enforceability in certain contexts.
- The scope appears aligned with recent pharmaceutical patents, emphasizing both composition and method claims for comprehensive coverage.
What is the patent landscape surrounding U.S. Patent 11,938,136?
Related patents:
