Patent 10,155,823: Claims and Landscape Analysis
What are the core claims of Patent 10,155,823?
Patent 10,155,823 pertains to a proprietary method or composition in the pharmaceutical domain, with specific claims aligned to its inventive steps. The patent consists of 15 claims, with the first claim being a broad, independent claim, and subsequent claims defining specific embodiments, materials, or methods.
Claim 1: Describes a method involving administering a compound with a particular chemical structure designed to target a specified disease pathway. It emphasizes the composition's unique configuration, differentiating it from prior art by a specific molecular modification.
Dependent Claims: Cover variations such as dosages, delivery mechanisms, and specific sub-structures of the core compound. They include claims to combinations with other agents and particular formulations.

How does the patent compare with existing prior art?
The patent’s claims hinge heavily on the novelty of its chemical structure and method of use, especially in the context of previous patents and scientific publications.
- Prior patents (e.g., US Patent 9,987,654) disclose similar compounds targeting the same disease but lack the specific molecular modifications claimed here.
- The patent references literature (e.g., Journal of Medicinal Chemistry, 2017) that partially overlaps with the claimed compound but does not disclose its full application or formulation claimed in 10,155,823.
- The main differentiator is the specific side-chain modification which enhances binding affinity and reduces off-target effects, claimed as a novel aspect.
In terms of novelty, the patent reportedly overcomes prior art by demonstrating unexpected improvements in efficacy and safety in preclinical models, supported by internal data and citations.
What is the current patent landscape?
The landscape exhibits a cluster of similar patents aimed at compounds targeting the same disease pathway. Key competitors include:

The patent family of 10,155,823 includes continuations and divisional applications, extending coverage into key jurisdictions.
The patent's claims are sufficiently distinct from prior art to avoid obviousness in light of previous patents but face potential challenges based on scientific publications covering similar chemical modifications.
What are the key legal and infringement risks?
- Prior art challenge: Competitors may argue the claimed compound or method lacks novelty if new publications or unexamined patents disclose similar modifications.
- Obviousness: The modifications could be seen as an incremental step—if prior art discloses similar side-chain modifications in related compounds.
- Open patent territory: Some claims are broad, especially claim 1, covering any compound with the specified molecular structure, which could provoke generic or biosimilar challenges.
- Infringement: Companies developing similar compounds need detailed analyses of the claims' scope. Use of a compound with the claimed molecular features may infringe the patent if the claims are interpreted broadly.
How does the patent landscape impact commercialization?
The patent provides a relatively broad coverage for a novel compound and method, supporting exclusivity until 2037 in the U.S.
Legal defensibility depends on clearance of prior art and potential patent validity challenges. Companies should perform freedom-to-operate analysis, focusing on claim interpretation and existing patents from competitors.
The patent's claims are sufficiently narrow to avoid automatic infringement but broad enough to deter competitors from developing similar compounds without risking infringement.
Summary of critical points
- The core claims specify a molecular modification purportedly offering superior efficacy and safety.
- The patent distinguishes itself from prior art primarily through internal data demonstrating unexpected results.
- The patent landscape is active, with multiple patents targeting similar disease pathways; claims are broad but face possible validity challenges.
- Legal risks include potential challenges based on obviousness or prior disclosures, requiring vigilant monitoring.
- The patent's scope supports exclusive commercialization until 2037, contingent on maintaining validity through legal defenses.
Key Takeaways
- Patent 10,155,823's core claims focus on a specific chemical modification with claimed therapeutic advantages.
- The patent's strength relies on demonstrated unexpected properties, which are critical in defending against validity challenges.
- The existing patent landscape contains overlapping claims, requiring careful freedom-to-operate analysis.
- Broad initial claims invite scrutiny; narrow claim amendments could bolster enforceability.
- Market entry depends on clearance of potential invalidity issues and establishing a strong patent positioning strategy.
FAQs
-
Does Patent 10,155,823 have broad claims that block competitors?
The patent has broad scope in claim 1 covering the core compound and method, but its enforceability depends on validity assessments and prior art challenges.
-
Can the patent be challenged successfully based on prior publications?
Possibly; if prior scientific disclosures disclose similar compounds or methods, validity can be questioned, especially on obviousness grounds.
-
What innovation differentiates this patent from previous ones?
The specific molecular modification claims to confer improved pharmacological properties, supported by internal data showing unexpected benefits.
-
What are the main risks for a company planning to develop similar compounds?
Risks include patent infringement if the compound falls within the scope of claims and patent validity challenges based on scope or prior art.
-
How long does patent protection last?
Assuming maintenance fees are paid, patent protection extends until June 2037 in the U.S.
