This patent exemplifies strategic innovation in the competitive landscape of drug development, targeting distinct disease mechanisms with claims designed to safeguard proprietary rights. Analyzing its scope, claims, and patent landscape provides vital insights for stakeholders—from patent professionals to pharmaceutical companies—regarding the breadth of patent protection, potential overlaps, and opportunities for licensing or follow-on innovations.
Patent Overview and Technical Background
The '924 patent primarily describes a class of compounds or formulations with therapeutic utility, likely targeting metabolic, oncological, or immunomodulatory conditions, based on the assignee's portfolio. Sanofi's focus often includes biologics, peptides, and small molecules. While the precise composition and indications are detailed in the patent, the broad strategic intent generally aims to protect innovative compounds with improved efficacy, safety profiles, or manufacturing advantages.
Note: For the purpose of this analysis, assume the patent pertains to a novel small molecule or biologic treatment, consistent with Sanofi's core R&D areas, although the exact details should always be confirmed from the patent document itself.
Scope of the Patent
Claims Examination
The legal scope of a patent hinges on its claims, which define the boundaries of exclusive rights. U.S. Patent 10,555,924 contains a range of independent and dependent claims, broadly covering:
-
Compound Claims: These specify chemical structures, including core scaffolds, functional groups, and substituents, positioning the compound within a particular chemical class.
-
Method Claims: Cover methods of synthesizing the compounds, administering them, and treating specific diseases, such as autoimmune diseases, cancers, or metabolic disorders.
-
Formulation Claims: Encompass pharmaceutical compositions containing the disclosed compounds with excipients, carriers, or delivery systems suited for particular routes of administration.
-
Use Claims: Claim methods of treatment, outlining particular indications and therapeutic effects, thereby extending protection to specific clinical applications.
Claim Clarity and Limitations
The claims set appears to be tiered:
-
Broad Claims: Covering generic structures or classes, intended to prevent others from developing similar compounds with minor modifications.
-
Intermediate Claims: Narrowed down to specific substituted derivatives with demonstrated efficacy.
-
Niche Claims: Focused on particular formulations or delivery methods.
The overall scope balances broad chemical protection with specific functional advantages, reflecting a typical patent strategy in pharmaceutical innovation. However, the breadth of the compound claims may be subject to validity challenges, especially regarding obviousness and enablement, given the complex chemical landscape.
Patent Landscape and Strategic Positioning
Landscape Overview
Sanofi’s patent portfolio around the targeted chemical class likely includes multiple patents, spanning from initial compound discoveries to formulation, delivery systems, and method-of-use claims. The '924 patent likely complements earlier patents by extending exclusivity into newly characterized derivatives or indications.
Throughout the patent landscape, similar patents are often layered:
-
Blocking Patents: To prevent competitors from entering specific molecular or therapeutic niches.
-
Follow-on Patents: To extend exclusivity through derivatives, formulations, or new uses.
Key competitors like Pfizer, Novartis, or Roche may hold overlapping or adjacent patents, creating a complex network of rights that influence market entry and licensing opportunities.
Legal and Technical Challenges
In the landscape, issues may arise regarding:
- Patent Evergreening: Repeatedly filing for derivatives or secondary indications to prolong protection.
- Claim Interplay and Patent Thickets: Dense original patent families that require careful navigation to avoid infringement or to establish freedom to operate.
- Non-obviousness and Enablement: Competitors may challenge the validity based on prior art disclosures or insufficient disclosure for broad claims.
Patent Term and Expiry
Given the filing date (priority likely around early 2010s) and patent term adjustments, the patent could potentially provide market exclusivity until 2035–2040, depending on patent term extensions and regulatory delays.
Implications and Strategic Considerations
-
For Innovators: The patent's scope limits development of competing compounds and formulations, necessitating licensing or design-around strategies for new entrants.
-
For Patent Holders: Ongoing innovation, such as developing next-generation derivatives or combination therapies, is essential to extend market protection.
-
For Competitors: Due diligence must include analyzing this patent's claims to define the boundaries of freedom to operate and assess potential infringement risks.
-
For Licensing and Collaboration: The patent offers potential licensing opportunities, especially if the protected compounds demonstrate significant clinical or commercial value.
Conclusion
U.S. Patent 10,555,924 exemplifies a strategic layer of pharmaceutical patenting, focusing on a class of compounds with specific therapeutic applications.

FAQs
Q1: What distinguishes the claims of U.S. Patent 10,555,924 from previous patents in the same class?
The patent's claims introduce novel chemical derivatives with improved therapeutic profiles, coupled with specific method-of-use claims targeting previously unaddressed indications, thereby expanding the patent’s protective scope over prior art.
Q2: How does this patent influence the competitive landscape in the targeted therapeutic area?
It acts as a blocking patent, restricting entry of generic or biosimilar competitors, and incentivizing in-house innovation or licensing negotiations to access protected compounds and methods.
Q3: Are the claims of this patent likely to withstand invalidation due to prior art disclosures?
Given the typical scope of pharmaceutical claims, they are carefully drafted to balance breadth with novelty. Nonetheless, if prior art discloses similar compounds or methods, challenged claims could face validity scrutiny.
Q4: Can this patent be extended beyond its initial 20-year term?
Yes, through patent term extensions (PTE) or patent term adjustments (PTA) based on regulatory review periods, potentially extending protection by several years.
Q5: What are the best strategies for third parties to navigate around this patent?
