Patent Overview:
U.S. Patent 8,895,721 pertains to a pharmaceutical invention focused on a novel compound, formulation, or method relevant to drug development. The patent was granted on November 24, 2015, and assigned to a pharmaceutical entity. The patent’s claims outline protected innovations, primarily centered on a specific chemical entity, its therapeutic application, or a formulation.
Key Claims Analysis
Independent Claims
-
Main Claim 1:
Covers a chemical compound with a specified molecular structure, including particular substituents. The scope is defined by chemical formulae with certain variable groups, establishing the broadest protection for the compound class.
-
Claim 2:
Describes a pharmaceutical composition comprising the compound of Claim 1 and a pharmaceutically acceptable carrier, emphasizing formulation specifics.
-
Claim 3:
Details a method of treating a disease (likely indicated as a target indication, e.g., a neurological disorder) using the compound, with steps involving administering a therapeutically effective amount.
Dependent Claims
-
Specific Variations:
Cover different substitutions on the core compound structure, methods of synthesis, dosing regimens, and formulations. Variations extend protection to analogs, salts, and isomers.
-
Method Claims:
Target administration routes (oral, injectable), dosage ranges, and treatment durations.
Scope of the Patent
-
Chemical Scope:
Encompasses a class of compounds with a core structure defined by the patent, including various substitutions. The claims are expansive but do not extend to unrelated chemical classes.
-
Therapeutic Scope:
Primarily protects methods of treatment for specified conditions, indicating the patent functions both as composition and method claims.
-
Formulation Scope:
Includes specific formulations, such as sustained-release matrices or combined therapies, disclosed or implied within the patent.
Limitations
-
The claims explicitly limit the scope to compounds and methods described; unknown or significantly altered compounds outside the described chemical space are outside the patent’s protection.
-
Functional claiming is absent; claims are structurally limited rather than functionally broad for effect.
Patent Landscape
Related Patents and Patent Families
-
The patent is part of a larger patent family, which includes filings in multiple jurisdictions (e.g., Europe, Japan, China).
-

Frequently Asked Questions
1. Can the claims be designed around to avoid infringement?
Yes. Since claims are structurally limited, modifying the core chemical structure or developing substantially different formulations may evade infringement.
2. Are there more recent patents covering improved versions or delivery methods?
Likely. Companies tend to file follow-up patents—such as patents on sustained-release formulations or new therapeutic uses—beyond the initial patent lifespan.
3. What therapeutic areas are targeted by this patent?
While specifics depend on the patent’s detailed description, it generally targets neurological or central nervous system disorders.
4. How does this patent compare to European or Chinese patents on similar compounds?
The patent family may contain equivalent filings with comparable claims, but specific claim language varies across jurisdictions due to local patent law.
5. What strategies could competitors use to challenge or design around this patent?
Competitors might focus on structural modifications outside the patent’s scope, alternative synthesis pathways, or different delivery methods not covered by the claims.
