Overview of Patent 9,290,504
Title: Methods of Treating Disease with Specific Compounds
Filed: October 25, 2013
Assignee: [Assignee Name], a prominent entity in pharmaceuticals
Focus: The patent covers a novel class of chemical compounds with therapeutic applications, potentially targeting specific pathological processes such as inflammation, autoimmune disorders, or metabolic diseases.
The patent's core lies in its innovative chemical structures, formulations, and methods of administering these compounds for disease treatment or management.
Scope and Claims Analysis
1. Core Claim Structure
The patent comprises multiple claims—independent and dependent—that define its scope:
- Independent claims generally cover specific chemical entities or classes, pharmaceutical compositions, and methods of health treatment involving these compounds.
- Dependent claims add refinements, such as formulation specifics, dosage forms, or particular methods of administration.
Example: An independent claim might stipulate a chemical compound characterized by a defined molecular structure, such as a specific heterocyclic core with substituents, combined with methods of its use in treating a disease like rheumatoid arthritis.
2. Scope of the Chemical Compounds
The patent broadly claims synthetic derivatives within a defined chemical space, often represented with Markush groups to encompass multiple structures. The scope includes:
- Variations of core chemical scaffolds.
- Substituents at specific positions, considering both minor modifications and more substantial structural variants.
- Prodrugs or salts of the claimed compounds.
The chemical scope is designed to maximize coverage, preventing competitors from designing around the patent by subtle structural changes.
3. Method of Use and Therapeutic Claims
- The patent extends claims to methods of treating specific diseases—likely autoimmune, inflammatory, or metabolic disorders—using the claimed compounds.
- Claims specify administering the compounds at effective doses, via routes such as oral, injectable, or topical applications.
- Some claims cover combination therapies with other drugs, enhancing the patent's breadth in multi-drug regimens.
4. Formulation and Delivery Claims
- Claims address pharmaceutical compositions, encompassing carriers, excipients, and delivery systems suited for stability, bioavailability, and patient compliance.
- Novel formulations or delivery methods, such as controlled-release or targeted delivery, are also claimed.
Legal and Strategic Scope
The patent's claim breadth offers a formidable barrier against generic entrants. By covering:
- A broad chemical space through Markush structures,
- Multiple therapeutic indications,
- Diverse administration routes,
- And combination therapies,
it establishes a comprehensive monopoly in its therapeutic niche, fostering exclusivity for the patent holder.
Patent Landscape Context
1. Preceding and Contemporaneous Patents
The patent landscape surrounding U.S. Patent 9,290,504 features:
- Prior art: Earlier patents or publications concerning similar chemical scaffolds or therapeutic applications. These may include foundational compounds or known drug classes.
- Citations: Both citing and cited patents, illustrating technological lineage and strategic positioning within the domain.
The patent likely cites prior art that describes similar core structures or differential modifications, emphasizing its novelty in substituents or methods.
2. Overlapping and Blocking Patents
In the landscape, patents from competitors or earlier filings may claim similar compounds or methods, creating potential patent thickets. The scope of 9,290,504 appears designed to navigate such complexities by:
- Incorporating unique substituent variations,
- Covering specific methods of synthesis, or
- Targeting novel therapeutic indications.
These strategies help mitigate patent challenges and carve out market exclusivity.
3. Geographic Patent Coverage
While this analysis emphasizes U.S. rights, corresponding patents exist internationally, primarily in jurisdictions like Europe, Japan, and China. Patent families often claim priority through PCT applications, enabling broad global protection.
Implications for Stakeholders
- Pharmaceutical Developers: The broad claim scope necessitates careful design-around strategies and patent clearance analysis.
- Legal Practitioners: The composition and use claims require diligent examination for potential infringement or validity challenges, especially regarding novelty and non-obviousness.
- Investors: The patent's defensive and offensive potential depends on its enforceability and ongoing prosecution strategies.
