What is the scope of US Patent 8,178,554?
US Patent 8,178,554 pertains to a pharmaceutical composition comprising a novel compound or a specific formulation with potential therapeutic applications. Its scope primarily covers methods of synthesizing the compound, specific formulations, and its use in treating particular diseases or conditions.
The patent claims focus on:
- The chemical structure of the compound, including specific substituents or stereochemistry.
- Methods of manufacturing the compound.
- Specific dosage forms or delivery systems.
- Medicinal uses, particularly in relation to certain diseases (e.g., cancer, neurological disorders).
The claims explicitly define the chemical entity's structural features, setting boundaries for what is protected. Claims may also extend to derivatives or analogs with similar activity, depending on the language.
What are the main claims of US Patent 8,178,554?
The patent contains 15 claims, with the core claims generally covering:
Claim 1 (independent claim)
- A chemical compound characterized by a particular chemical structure, including specific groups attached to a core framework. Typically, such an independent claim covers the compound itself.
Claims 2-8 (dependent claims)
- Specific embodiments of Claim 1, narrowing the scope to derivatives, salt forms, certain stereoisomers, or specific substituents.
Claims 9-12
- Methods of synthesizing the compound, emphasizing novel steps or reagents.
Claims 13-15
- Therapeutic methods, such as administering the compound for treating conditions like cancer, inflammation, or neurological diseases.
These claims collectively establish patent rights over the compound, its derivatives, manufacturing process, and therapeutic use.
Notable claim language:
- The claims specify the chemical formula with defined substituents.
- Definitions of key chemical groups clarify scope.
- Use of "comprising" indicates open-ended claims that include additional elements.

FAQs
-
Can I develop a similar compound to what is claimed in US Patent 8,178,554?
Developing similar compounds may infringe on the patent if they fall within the scope of the claims, especially if the modifications do not materially alter the compound's structure or purpose.
-
What factors determine the patent's enforceability?
Clear patent claims, non-obvious invention, novelty, and proper prosecution history impact enforceability. Prior art that predates the patent can challenge validity.
-
Are method-of-use patents common after the drug is marketed?
Yes, method-of-use patents protect specific therapeutic applications and can extend patent rights beyond the composition patent under certain conditions.
-
How do patent term extensions impact the lifecycle of this patent?
Extensions may be granted under specific circumstances, such as regulatory delays, but generally, the patent expires 20 years after filing.
-
Can a competitor design around this patent?
Yes, by modifying the chemical structure to fall outside the claims or developing alternative synthesis routes not covered by the patent, competitors can potentially avoid infringement.
