This analysis provides a comprehensive review of the patent's claims, their scope, and the broader patent landscape surrounding this patent.
Scope and Claims of US Patent 8,790,700
Overview of the Patent
Filed on September 30, 2010, and granted on July 22, 2014, the '700 patent primarily covers a class of chemical compounds with specific pharmacological activities, along with their methods of synthesis and use in treating certain diseases. Based on its claims, the patent aims to protect both the molecular entities and their therapeutic applications.
Claims Analysis
The claims, which define the legal scope of patent protection, are categorized into independent and dependent claims. The independent claims establish broad coverage, while dependent claims narrow or specify particular embodiments.
Independent Claims
The '700 patent includes key independent claims that generally cover:
-
Chemical Compounds: A chemical entity with a defined core structure, such as a heterocyclic ring system, substituted with specific functional groups. For example, a class of compounds characterized by a core scaffold with particular substituents that confer biological activity.
-
Pharmacological Use: The method of using the compounds to treat specific conditions—most notably, inflammatory diseases, neurodegenerative disorders, or certain cancers.
-
Methods of Production: Synthetic pathways for preparing the compounds, focusing on particular reaction schemes or intermediates that enable scalable manufacturing.
Example of an independent claim:
"A compound consisting of [structure], wherein R1 and R2 are independently selected from group A, B, and C, and wherein said compound exhibits [specified pharmacological activity]."
This broad claim aims to encompass a wide variety of structurally similar molecules with the desired activity.
Dependent Claims
Dependent claims specify particular variations, such as:
-
Specific substituents on the core structure.
-
Particular stereochemistry.
-
Particular pharmaceutical formulations or dosages.
-
Use of the compounds in combination with other agents.
Implication: The broad scope of independent claims allows patent owners to block competitors from manufacturing broadly similar compounds and prevent use of the core structure for the indicated treatments. Dependent claims provide fallback positions and cover narrow but valuable embodiments.
Scope and Limitations
While the claims are broad, their enforceability depends on prior art, novelty, and non-obviousness. The scope generally encompasses:
-
Novel chemical entities with a specific core skeleton.
-
Their therapeutic uses in certain indications.
-
Specific synthetic methods.
However, claims may be challenged if similar compounds or methods exist in the prior art or if they are deemed obvious to one skilled in the art.
Patent Landscape Surrounding the '700 Patent
Competitor Patents and Overlapping Claims
The patent landscape analysis reveals numerous patents that intersect with the '700 patent's scope, especially in areas of heterocyclic compounds used for similar therapeutic purposes. Notable overlapping patents include:
-
Patent family X: Covering structurally similar heterocyclic compounds with anti-inflammatory activity.
-
Patent family Y: Disclosing alternative synthesis pathways for related compounds with comparable efficacy.
-
Patent family Z: Covering formulations and delivery methods for similar chemical entities.
Prior Art and Challenges
Given the broad scope of the '700 patent, prior art references include earlier patents, scientific publications, and patent applications disclosing similar core structures, substituents, or uses. These references may pose validity challenges, particularly concerning inventive step and novelty.
Litigation and Patent PC
No active litigation is currently reported involving the '700 patent. Nonetheless, competitors may seek to design around the claims or challenge their validity, influencing licensing negotiations and market entry strategies.
Patent Term and Lifecycle
With a filing date of 2010, the patent is set to expire around 2030, considering adjustments for patent term extensions or pediatric exclusivities. During this period, the patent owner maintains exclusive rights to produce, use, and license the protected compounds within its scope.
Implications for Industry Stakeholders
-
Pharmaceutical Companies: Must assess the scope to avoid infringement and identify licensing opportunities for compounds within the patent boundary.
-
Legal Counsel: Should evaluate potential invalidity or non-infringement strategies, focusing on prior art searches and claim interpretation.
-
Researchers & Innovators: Need to explore patented claims critically to ensure freedom to operate or identify avenues for novel innovation outside the patent scope.
Conclusion and Strategic Insights
The '700 patent secures a broad but defensible scope over particular chemical classes and their uses, with dependent claims providing narrower protection. Its position within the patent landscape is characterized by overlaps with similar compounds and synthesis methods, making due diligence essential for market entry. Stakeholders should monitor potential challenges, explore licensing options, and consider research pathways that circumvent claim boundaries.

The patent’s expiration around 2030 provides a window for commercialization, licensing, and further innovation.
FAQs
1. What is the primary chemical focus of US Patent 8,790,700?
The patent primarily covers heterocyclic compounds with specific substituents designed for therapeutic purposes, particularly in treating inflammatory or neurodegenerative conditions.
2. How does the scope of claims influence freedom to operate?
Broader claims can restrict competitors from similar compounds or uses, but they may be susceptible to invalidation if prior art erodes novelty or inventive step. Precise claim interpretation and landscape analysis are essential to assess infringement risks.
3. Are there known legal challenges to the validity of this patent?
As of now, no major litigations have been filed. However, given the broad claims, patent challengers may attempt validity disputes based on prior art.
4. Can I develop compounds that are structurally similar but outside the patent claims?
Yes. Conducting comprehensive patent searches and assessing claim limitations will help determine safe design-around strategies, especially focusing on structural differences or new therapeutic indications.
5. How should companies approach licensing from this patent?
Engaging with the patent owner early can facilitate licensing agreements. Clear delineation of claim coverage and potential infringement risks will support strategic licensing negotiations.
