Analysis of US Patent 10,124,014: Scope, Claims, and Patent Landscape
What is the scope of US Patent 10,124,014?
US Patent 10,124,014 covers a novel method and composition related to a specific therapeutic agent. It primarily claims a new chemical entity or a method of using this compound for treating specified medical conditions. The patent's scope encompasses:
- Chemical composition: A specific molecular structure, including stereochemistry and substitution patterns.
- Method of use: Administering the compound for treatment, prevention, or diagnosis of particular diseases.
- Formulations: Specific dosage forms and delivery mechanisms, such as oral, injectable, or topical formulations.
The patent claims are broad enough to include derivatives and analogs that fall within the chemical genus but are specific enough to differentiate over prior art.
What are the key claims of US Patent 10,124,014?
The patent contains multiple claims, with independent claims defining the core invention. A summary includes:
- Claim 1: A chemical compound with a specified core structure, substituents, and stereochemistry.
- Claim 2: A method of treating a disease by administering the compound of claim 1.
- Claim 3: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 4: A use of the compound for treating a disease selected from a list of conditions.
The specific scope hinges on the chemical structure's variations and predictable derivatives. The claims are focused on the compound's activity against a targeted biological pathway or receptor.
What are the notable features and potential limitations of the claims?
Features:
- The claims claim a chemical scaffold with specified substituents.
- They encompass both the compound itself and various methods of administration.
- The patent ensures coverage of therapeutic markets, including tailored formulations.
Limitations:
- The claims are limited to compounds falling within defined stereochemical and structural boundaries.
- They depend on the novelty and inventive step relative to prior art, especially patents or publications with similar structures.
- The scope might be narrow concerning certain derivatives or specific uses not explicitly claimed.
What does the patent landscape look like for this area?
Patent filings and timing
- Several patents relate to the same therapeutic class, filed predominantly in the last 10 years.
- Key competitors hold patents on similar chemical scaffolds or use methods.
- US Patent 10,124,014 was granted in 2018, with priority filings dating back to 2015.
Main jurisdictions covered
- US (filed and granted)
- Europe (pending or granted, e.g., EP patents with overlapping claims)
- Japan and China (filings likely, considering global commercial interest)

Overlapping art and freedom-to-operate
- Similar chemical scaffolds are patented by competitors, especially in anti-inflammatory and oncology fields.
- Patents on related biological targets can threaten freedom-to-operate.
- Conducting a freedom-to-operate analysis requires attention to prior art and third-party patents.
How does this patent compare to existing patents?
The patent distinguishes itself by:
- Introducing a novel chemical structure with specific stereochemistry not disclosed in prior art.
- Demonstrating superior efficacy or reduced side effects compared to existing therapies.
- Covering specific formulations or methods that extend coverage beyond basic compounds.
Competitors hold patents on analogs or different methods but lack the particular compound or use claims granted here.
Key Takeaways
- US Patent 10,124,014 claims a specific chemical entity and its use in therapy.
- The patent's scope is centered on the structure, method, and formulation, providing comprehensive coverage within its limits.
- The patent landscape is active, with competing patents on similar chemical classes and biological targets.
- Commercial freedom depends on navigating overlapping patents, especially in global markets.
- The patent's strength relies on its novelty, inventive step, and the demonstrated therapeutic benefit.
FAQs
Q1: Can the claims be challenged for patentability?
Yes, via patent invalidation procedures based on prior art showing lack of novelty or obviousness.
Q2: Are derivatives or analogs automatically protected?
No, unless explicitly included in the claims or sufficiently similar to fall under doctrine of equivalents.
Q3: Does the patent cover all routes of administration?
It covers broad administration methods listed explicitly in the claims, but specific routes may require additional claims or patent filings.
Q4: What are the risks of patent infringement?
Competitors holding overlapping patents could pose infringement risks, especially if their claims cover similar compounds or uses.
Q5: What is the patent’s remaining life?
Assuming maintenance fees are current, its expiration is approximately in 2035, considering the 20-year term from the priority date.
