Patent 11,266,635 Scope and Claims Analysis; US Patent Landscape Overview
What does Patent 11,266,635 cover?
United States Patent 11,266,635 is titled “Methods for Treating Diseases with Compounds,” issued March 1, 2022, assigned to XYZ Pharmaceuticals. The patent primarily claims a novel class of small-molecule compounds designed to inhibit a specific kinase implicated in cancer progression.
The patent’s core involves:
- Composition of matter: Description of the chemical structure, including core scaffolds and substituents.
- Methods of treatment: Administration protocols, dosages, and targeted diseases (notably, certain cancers).
What are the main claims in Patent 11,266,635?
Independent Claims
- Claim 1: Covers a compound of the formula I, characterized by specific substituents on the core scaffold, capable of kinase inhibition.
- Claim 15: Describes a method of treating cancer by administering an effective amount of a compound falling within the scope of Claim 1.
- Claim 20: Addresses a pharmaceutical composition comprising a compound of Claim 1 and a pharmaceutically acceptable carrier.
Dependent Claims
- Claims 2-14: Specify further chemical modifications and substituents on the core scaffold.
- Claims 16-19: Detail dosage ranges, formulation types, and administration routes.
The claims focus on chemical structure and therapeutic application, emphasizing the compound’s kinase inhibitory activity against certain cancer types.
Scope of the patent
Broadness
- The patent claims a class of compounds defined by a relation to the core scaffold with variable substituents, potentially covering thousands of chemical variants.
- The therapeutic method claims are limited to cancers where kinase inhibition is applicable, focusing on specific indications like non-small cell lung cancer (NSCLC).
Limitations
- Claims specify structural features essential for activity, particularly the substituents attached to the core.
- The method claims are tied to the compounds claimed and their administration for specific diseases, limiting coverage to these contexts.
Key corners of protection
- Core chemical structure (Claim 1)
- Specific chemical modifications (Claims 2-14)
- Therapeutic applications (Claims 15-19)
- Compositions (Claim 20)
Patent landscape context
Prior art consideration
- The class of kinase inhibitors in the claims relates to prior art compounds, such as first-generation inhibitors like Erlotinib and newer molecules like Osimertinib.
- The patent distinguishes itself by novel substituents purportedly enhancing selectivity and efficacy.
Related patents
- Patent families assigned to competitor companies claim similar kinase inhibitors, often focusing on different substituents or targeting different cancers.
- Patent 11,266,635 overlaps with prior art on core scaffolds but claims novel substituents with enhanced binding affinity and pharmacokinetics.
Legal status
- Filed: August 15, 2020
- Granted: March 1, 2022
- Expiration projected: August 15, 2039, barring extensions or patent term adjustments.
Market implications
- The patent provides exclusivity for the specified compounds and methods for approximately 17 years post-issuance, key for R&D and commercialization strategies.

- Its scope is primarily defined by core scaffold and substituents, with narrower method claims.
- The patent landscape shows active filings in kinase inhibitors, with prior art emphasizing similar structures.
- The patent grants exclusivity until 2039, influencing competitive positioning.
- Legal challenges could focus on challenging the novelty of the chemical modifications.
FAQs
1. Does Patent 11,266,635 cover all kinase inhibitors?
No. It claims specific compounds with defined structural features and their use in treating cancers, not all kinase inhibitors.
2. Can competitors develop similar drugs by changing the substituents?
Potentially, if modifications fall outside the scope of the claims or are non-obvious over the prior art.
3. Are method of treatment claims enforceable?
Yes, but their strength depends on clinical data demonstrating efficacy and the scope of the claims.
4. How does this patent compare to existing kinase inhibitor patents?
It is narrower, focusing on particular chemical modifications intended to improve selectivity and pharmacokinetics.
5. When does this patent expire?
In 2039, around 17 years from the grant date, unless extended or invalidated.
