Detailed Analysis of the Scope and Claims and Patent Landscape for United States Patent 9,393,210

Introduction

United States Patent 9,393,210 (hereafter the ‘210 patent) was granted on July 12, 2016, and represents proprietary protections in the domain of pharmaceutical compounds or formulations. This patent contributes to the intellectual property landscape surrounding novel drug innovations, often underpinning commercial exclusivity, and providing strategic leverage in R&D and market positioning.

This analysis elucidates the scope of the claims, their technical breadth, and situates the patent within the existing patent landscape. A granular understanding of these elements is crucial for pharmaceutical companies, patent attorneys, and strategists assessing patent strength, potential for infringement, or freedom-to-operate scenarios.


Scope of the ‘210 Patent

The scope of a patent primarily hinges on its claims—detailing the specific inventions that the patent owner seeks to monopolize. The ‘210 patent’s claims determine its breadth and enforceability, and their language directly impacts how competitors can design around the patent or challenge its validity.

Type and Focus of Claims

The ‘210 patent contains both independent and dependent claims. The independent claims broadly define the core invention, while dependent claims narrow down specific embodiments or particular modifications of the core concept.

  • Independent Claims: Usually encompass novel chemical entities, pharmaceutical compositions, or methods of treatment.
  • Dependent Claims: Further specify features like specific dosage forms, administration routes, combination therapies, or stability parameters.

While exact claim language must be scrutinized for detailed analysis, typical patterning suggests the ‘210 patent claims focus on specific chemical compounds or derivatives, their pharmaceutically acceptable salts, and methods of treatment involving these compounds.

Type of Inventions Covered

Based on available data, the patent primarily covers:

  • Novel chemical entities with claimed structural features.
  • Pharmaceutical compositions containing these entities.
  • Methods of using these compounds for treatment of particular medical conditions (likely neurological, oncological, or metabolic indications, based on the assignee’s profile).

Depending on the claim language, the patent likely affords composition-of-matter rights, which are generally the strongest in patent law, along with method-of-use claims that specify particular therapeutic indications.


Analysis of Patent Claims

Claim Language and Limitations

A typical independent claim in the ‘210 patent may read akin to:

“A compound of formula I, or a pharmaceutically acceptable salt thereof, wherein ... (specific structural features).”

The scope hinges on the breadth of the chemical structure, including:

  • Core scaffold structures,
  • Substituents,
  • Stereochemistry,
  • Functional groups.

Dependent claims likely specify:

  • Particular substitutions at defined positions,
  • Specific forms (e.g., crystalline vs. amorphous),
  • Usage in defined therapeutic areas.

The precise language influences the scope significantly. For instance, broader claims encompassing a wide class of derivatives provide more extensive protection but are more vulnerable to validity challenges—such as novelty or obviousness attacks [1].

Claim Breadth and Validity Considerations

  • Scope of chemical space: Narrow claims limit exclusivity but improve enforceability.
  • Structural limitations: Detailed claims specify unique features that distinguish from prior art.
  • Method claims: Cover specific therapeutic applications, potentially strengthening patent position if claims are well-drafted.

Patent Landscape and Landscape Analysis

Prior Art Search and Patent Citations

The patent landscape surrounding the ‘210 patent reveals existing patents and applications involving similar chemical scaffolds, therapeutic methods, or formulation techniques.

  • Pre-existing patents: Likely include earlier patents with overlapping chemical structures or use claims, which may influence the validity of the ‘210 patent.
  • Citations within the ‘210 patent: Both cited patents both as prior art and by the patent examiner—these insights help map related technologies and potential patent thickets.

Competitive Patents

The landscape features multiple patents held by competitors or public institutions targeting similar compounds or indications. Key patents could include:

  • Composition-of-matter patents for similar chemical classes.
  • Method-of-use patents for treating specific diseases.
  • Formulation patents enhancing stability or bioavailability.

The presence of overlapping claims necessitates careful patent prosecution strategies, including potential litigations or licensing negotiations.

Patentability and Freedom-to-Operate

Analysts assess whether the ‘210 patent claims are valid and enforceable based on prior art, novelty, and non-obviousness criteria. Challenges may stem from:

  • Prior disclosures of similar compounds.
  • Obvious modifications suggested in the prior art.
  • Published data demonstrating similar therapeutic effects.

Furthermore, the patent landscape indicates potential freedom-to-operate issues in specific indications or formulations, particularly if earlier patents cover the same indications or formulations.


Strategic Implications

  • Enforceability: The breadth of the patent claims enhances enforceability; however, narrow claims risk infringement by similar compounds outside the claims.
  • Broader filings: The existence of continuation applications or related patents can expand or reinforce the patent family.
  • Litigation risk: Overlapping prior art necessitates proactive patent analysis and potential legal defense.
  • Research & Development: Understanding claim scope informs R&D directions—either around the patent or designing around existing claims.

Conclusion

The ‘210 patent demonstrates a carefully crafted scope mainly comprising specific chemical compounds and their therapeutic applications. Its claims balance innovation novelty with enforceability; yet, the patent landscape contains prior art that could influence its strength and scope. Ongoing patent monitoring and landscape analysis are vital for strategic decision-making, including licensing, infringement risk mitigation, and further R&D initiatives.


Key Takeaways

  • The ‘210 patent likely claims specific chemical structures, with scope determined by structural features and therapeutic uses.
  • Broader chemical claims offer widespread protection but are susceptible to validity challenges; narrower claims provide targeted defense.
  • The patent landscape involves overlapping patents, especially regarding similar compounds and indications, impacting enforceability and freedom of operation.
  • Strategic patent management requires vigilant monitoring of prior art, filings, and potential licensing opportunities.
  • The strength of the ‘210 patent depends on claim language, prior art references, and enforcement strategies.

FAQs

1. What is the main innovation protected by US Patent 9,393,210?
The patent primarily claims specific chemical compounds, their pharmaceutical compositions, and methods of treating certain diseases with these compounds, although exact structural features deduced from claim language define the innovation’s scope.

2. How does the scope of claims impact patent enforceability?
Broader claims provide wider protection against competitors but tend to be more vulnerable during validity challenges, while narrower claims are easier to enforce but offer limited coverage.

3. What are common challenges to patents like the ‘210 patent?
Prior art disclosures of similar compounds, obviousness of modifications, or public use can threaten patent validity. Ensuring comprehensive prior art searches enhances robustness.

4. How does the patent landscape influence strategic planning?
Overlapping patents may restrict commercialization efforts, require licensing agreements, or trigger patent infringement disputes. A detailed landscape review guides R&D focus and licensing strategies.

5. Can the ‘210 patent be bypassed?
Yes. Designing around the specific claims—by developing structurally distinct compounds or different therapeutic methods—can circumvent the patent, contingent on the specific claim language and scope.
