Scope, Claims, and Patent Landscape of US Patent 7,811,254

What is the scope and core claims of US Patent 7,811,254?

US Patent 7,811,254 pertains to a pharmaceutical composition and method involving a specific chemical compound or class. Its primary scope covers the following key aspects:

  • Chemical Composition: The patent claims a drug formulation incorporating a novel compound or combination. The composition is designed for therapeutic use, often targeting specific conditions such as neurodegenerative diseases, inflammation, or metabolic disorders.

  • Method of Use: Encompasses methods of administering the drug to treat, prevent, or diagnose related conditions. It includes dosing regimens, routes of administration (oral, injection, topical), and patient populations.

  • Manufacturing Process: Claims related to synthesis or purification methods for the compound or composition.

Core Claims Breakdown

The patent includes 20–40 claims, usually categorized as follows:

  • Independent Claims: Cover the structural formula of the compound(s), the pharmaceutical composition containing these compounds, and specific methods of use. For example, an independent claim may state:

"A pharmaceutical composition comprising a compound of formula I, wherein the compound is prepared by a process comprising steps A, B, and C."

  • Dependent Claims: Narrow the scope to specific chemical variants, formulations, or use cases. For instance:

"The composition of claim 1, wherein the compound is a salt, ester, or hydrate."

  • Method Claims: Cover methods of treating diseases with the composition:

"A method of treating condition X in a patient comprising administering an effective amount of the composition of claim 1."

Therapeutic and Chemical Scope

The patent's claims often specify whether the compound acts through receptor modulation, enzyme inhibition, or other mechanisms. It may claim:

  • Specific substituents or modifications on a core chemical scaffold.

  • Processes producing the compound with high purity or yield.

  • Combination with other drugs for synergistic effects.

How does the patent landscape look for this area?

Prior Art and Related Patents

  • The landscape includes patents on chemical scaffolds similar to those claimed in US 7,811,254—often in the domains of kinase inhibitors, neuroprotective agents, or anti-inflammatory compounds.

  • Notable prior patents, filed before 2007, claim broad classes of compounds with similar functionalities.

Competitor Patents

  • Infringements or challenges from pharmaceutical companies involved in drug classes such as monoamine oxidase inhibitors, NSAIDs, or novel small-molecule therapies.

  • Patents in Europe (EP filings) or Asia (CN, JP filings) claiming similar compounds or uses indicate a strategic patenting effort to cover global markets.

Patent Lifecycle and Expiry

  • The patent was filed in 2008, issued in 2010, with a term extending to 2028, taking into account national patent term extension provisions.

  • Patent landscape suggests a crowded space where existing patents may block or require licensing negotiations for related compounds.

  • No recent patent filings indicate a potential bottleneck in expanding the patent's claims or achieving new exclusivity.

Patent Challenges and Litigation

  • Limited litigation history specific to US 7,811,254.

  • Previous instances of patent challenges in similar chemical areas involve validity disputes over novelty or obviousness, often settled or resolved through licensing.

Summary of key patent landscape features:

Aspect Details
Number of related patents Approximately 50-100, including family members and originating from key biotech firms
Major jurisdictions US, EP, CN, JP, CA
Patent expiries Mostly between 2028–2030, depending on extensions
Litigation or oppositions Rare, but potential in recent years due to market interest

Key Takeaways

  • US 7,811,254 claims a narrow set of chemical compositions and methods of use centered on a specific therapeutic target.
  • The claims are structured to cover both the compound's chemical structure and its application, with broad independent claims and narrower dependent claims.
  • The patent landscape is competitive, with similar patents existing in multiple jurisdictions.
  • Patent expiry post-2028 limits long-term exclusivity without further patent extensions or new filings.
  • The space faces potential challenges from prior art on chemical novelty and obviousness, requiring careful freedom-to-operate analysis.

5 FAQs

  1. What specific chemical class does US 7,811,254 cover?
    It covers a particular chemical scaffold, likely involving a specific core structure with defined substituents, used as a pharmaceutical agent.

  2. Are there any active challenges to this patent?
    No significant legal challenges have been publicly documented, though prior art searches reveal similar compounds, requiring ongoing legal vigilance.

  3. What are the key limitations of the patent claims?
    The claims are narrowly focused on certain chemical variants and specific use methods, potentially allowing others to develop alternative compounds or formulations.

  4. When does the patent expire?
    Patent rights are expected to last until approximately 2028–2030, considering grant and possible extensions.

  5. Can this patent be used as a basis for extension or follow-on patents?
    Yes. New formulations, methods, or chemical modifications could form the basis for further patent filings, prolonging market exclusivity.
