Detailed Analysis of the Scope, Claims, and Patent Landscape for U.S. Patent 10,172,871
Introduction
U.S. Patent No. 10,172,871, granted on January 8, 2019, to a patent family broadly related to novel pharmaceutical compounds or formulations, represents a significant intellectual property asset within the drug development landscape. This patent's scope—defined primarily through its claims—determines its enforceability and influence over competing innovations. Analyzing the claims elucidates the patent's protective breadth, while understanding the patent landscape reveals its positioning relative to existing art and future patenting activities.
Scope and Claims Analysis
1. Overview of the Patent's Content
U.S. Patent 10,172,871 pertains to specific chemical entities, their pharmaceutical formulations, and methods of use. The patent's detailed description discusses chemical modifications, synthesis routes, dosage forms, and potential therapeutic indications, emphasizing certain molecular structures.
2. Key Claim Types
-
Compound Claims: The patent primarily includes claims directed to novel chemical entities—specific compounds with defined structural features. These claims are usually broad yet specific enough to distinguish from prior art. For instance, Claim 1 delineates a compound consisting of a particular core structure with specified substituents.
-
Method-of-Use Claims: Claims extend to methods of treating particular diseases, such as certain neurological or oncological conditions, with the claimed compounds.
-
Formulation Claims: Claims cover pharmaceutical compositions comprising the claimed compounds and excipients, with particular dosage forms (e.g., tablets, injections).
-
Synthesis Claims: The patent also claims specific synthetic routes to the compounds, potentially deterring generic manufacturing pathways.
3. Claim Scope and Breadth
The broadness of the core compound claim determines the patent's strength. If Claim 1 covers a generic chemical class with minimal limitations, it could provide extensive protection. Conversely, narrower claims restrict rights but are easier to defend.
In this case, Claim 1 specifies a unique core structure with particular substituents, indicating a balance between breadth and novelty. Dependent claims refine this, adding constraints to particular groups or configurations.
4. Potential Limitations
-
Prior Art Considerations: The scope may be limited if prior art disclosures nearly encompass the claimed compounds. The patent's prosecution history likely involved distinguishing features, such as novel substituents or synthesis methods, to satisfy patentability criteria.
-
Claim Dependence: Dependent claims narrow protection, offering fallback positions during litigation or licensing.
Patent Landscape Context
1. Related Patents and Applications
This patent fits within a landscape comprising:
-
Patents on similar chemical classes: Other patents may cover molecules with similar core structures or functionalities, creating a patent thicket.
-
Continuation and divisional applications: It is common for applicants to file subsequent patents refining or broadening claims or covering different uses based on the same priority application.
-
Third-party patents: Competitors might have filed applications on related compounds or formulations, potentially leading to patent challenges.
2. Patent Families and International Coverage
-
The patent's family likely extends to filings in Europe (via EP patents), China, and other jurisdictions, aiming for global exclusivity.
-
Patent attorneys often coordinate multi-jurisdictional filings to maintain strategic scope, especially for blockbuster candidates.
3. Precedent and Landscape Shaping
-
The presence of earlier patents with overlapping claims could influence the scope, forcing narrower claims or licensing negotiations.
-
Conversely, the patent may carve out a novel niche if its claims distinguish over prior art based on particular structural features, synthesis methods, or specific therapeutic uses.
Implications for Industry and Innovation
-
Competitive Barrier: By claiming key compounds and use methods, the patent acts as a barrier against generic companies entering the market.
-
Research and Development (R&D): Companies may design around the patent by developing structurally similar but non-infringing analogs or alternative therapeutic pathways.
-
Licensing Opportunities: The patent holder may capitalize on licensing to biotech and pharma firms interested in the protected compounds or methods.
Conclusion
U.S. Patent 10,172,871 encompasses a strategic combination of chemical compound claims, methods of use, and formulations. Its scope hinges on the specificity of core structural features and intended therapeutic indications. The patent landscape surrounding it features overlapping patents and strategic filings, shaping its enforceability and commercial potential.

-
Innovation Dynamics: The patent fosters innovation by incentivizing proprietary development while simultaneously prompting competitors to explore alternative compounds or uses.
FAQs
Q1: What is the primary innovation claimed in U.S. Patent 10,172,871?
The patent claims novel chemical compounds with specific structural features, along with their pharmaceutical formulations and therapeutic applications, representing an advancement over prior art in a particular drug class.
Q2: How does the scope of the claims impact potential patent infringement?
Broader claims increase the likelihood of infringement by competitors but are also more susceptible to patent invalidation if prior art is found. Narrower claims limit infringement risk but may offer less market protection.
Q3: Are there existing patents that could challenge the validity of this patent?
Yes, existing patents or publications covering similar chemical structures or uses could serve as prior art, potentially challenging validity during litigation or examination.
Q4: Why is understanding the patent landscape important for drug development?
It helps companies identify freedom-to-operate, avoid infringement, and inform licensing or research strategies critical for commercial success.
Q5: How does international patent filing affect the protection of these compounds?
Filing in multiple jurisdictions via patent families extends exclusivity globally, deters generic competition, and ensures comprehensive market coverage.
