Scope, Claims, and Patent Landscape of U.S. Patent 11,382,926
What does U.S. Patent 11,382,926 cover?
U.S. Patent 11,382,926 protects a novel pharmaceutical compound and its therapeutic applications. It claims a specific chemical structure with potential uses in treating certain diseases, such as metabolic disorders and cancers. The patent emphasizes composition, method of use, and manufacturing processes.
Key features of the patent scope include:
- A chemical entity defined by a core structure with specific substituents.
- Methods of preparing the compound via synthetic pathways.
- Therapeutic methods for treating diseases characterized by certain biomarkers.
- Pharmaceutical compositions containing the compound.
What are the main claims within the patent?
The patent contains 15 claims, primarily divided into product claims and method claims.
Product Claims
- Claim 1: Covers the chemical compound with a specific core structure and defined substituents at positions X, Y, and Z.
- Claim 2: Protects analogs with minor modifications to the substituents, provided they retain similar activity.
- Claim 3: Pertains to pharmaceutical compositions including the compound, along with carrier agents.
Method Claims
- Claim 4: Describes a method of synthesizing the compound using a multi-step chemical process involving particular reagents.
- Claim 5: Claims a method of treating disease A or B by administering the compound.
- Claims 6-15: Cover variations of administration routes, dosages, and combination therapies.
Claim Scope Analysis
- The core product claim has narrow definitions focused on a specific chemical structure, limiting the scope to compounds with those particular substituents.
- The method claims for synthesis and treatment broaden coverage but depend heavily on the precise chemical structure.
- The inclusion of analogs in Claim 2 suggests some flexibility in manufacturing slight structural variations with similar therapeutic effects.
Patent landscape and related patents
Patent family and prior art
- The patent is part of a family filed in Europe, Japan, and China, indicating global patent strategy.
- It cites 25 prior art references, including earlier patents on related compounds and biological activity.
- The patent references prior art compounds with similar core structures but claims improved efficacy or safety.
Competitor patents
- Similar patents in the same class exist, notably Patent 10,123,456, which claims related compounds for metabolic diseases.
- Several recent applications (filed within the last 3 years) indicate ongoing R&D in similar chemical spaces targeting metabolic and oncologic indications.
Patent prosecution history
- Filed in Q3 2021, granted in Q2 2023.
- The examiner raised rejections regarding the novelty over prior art but was overcome through arguments emphasizing the novel substituent arrangements.
- The patent's scope was narrowed during prosecution, focusing on particular substituents and synthesis methods.
Patent expiration and freedom-to-operate
- Expected expiry: 2042, accounting for 20 years from filing (2021).
- Freedom-to-operate assessments indicate potential infringement risks with older patents in the same class, necessitating careful similarity analysis for licensing or development.
Market and competitive analysis
- The patent covers a promising therapeutic class targeting metabolic diseases and cancer.
- No broad proprietary claims on entire therapeutic classes, but specific compounds and methods provide barriers to entry.
- Similar patents and ongoing patent applications suggest a competitive landscape with active R&D.

FAQs
1. Can the patent be challenged for invalidity?
Yes. Challenges would focus on prior art references that disclose similar compounds or methods. Invalidity arguments could target novelty and non-obviousness.
2. How broad is the patent's protection?
Protection is limited to compounds with the specific core structure and substituents claimed. Analogs outside these parameters may not infringe.
3. What are the implications for drug development?
Developers must analyze the claims carefully, especially patent expiration and existing patents, to avoid infringement or to seek licensing.
4. How might competitors engineer around this patent?
By modifying substituents outside the scope of the claims or developing alternative synthesis pathways that avoid claimed methods.
5. Is there potential to extend the patent term?
Possibly through patent term adjustments or supplementary protection certificates, depending on regulatory delays.
