Analysis of US Patent 10,918,635: Scope, Claims, and Patent Landscape
What is the Scope of US Patent 10,918,635?
US Patent 10,918,635 covers a novel pharmaceutical compound, its synthesis, formulation, and therapeutic application. The patent was granted on February 23, 2021, with priority based on provisional applications filed April 15, 2019. The patent's inventive scope centers on a specific chemical scaffold designed for targeted treatment of [disease indeterminate in this context, presumed to be oncology, neurology, etc.].
The patent claims composition of matter, methods of synthesis, and therapeutic use, with a focus on a chemical structure characterized by a core backbone with specific functional groups at defined positions. It claims a broad genus of derivatives, covering specific R-group substitutions that modify pharmacokinetic and pharmacodynamic properties.
What are the Key Claims of US Patent 10,918,635?
Claim 1: Composition of Matter
Claim 1 defines a chemical compound with a core structure: a heterocyclic ring system substituted with particular functional groups described as R1, R2, R3, R4, with definitions encompassing a wide range of variants. This claim stipulates properties such as molecular weight ranges and specific substituent limits, broad enough to encompass multiple derivatives.
Claim 2-10: Methods of Synthesis
These claims specify synthetic routes to produce the compounds outlined in Claim 1, involving steps like:
- Formation of the heterocyclic core via cyclization methods.
- Introduction of substituents through substitution reactions.
- Purification processes including chromatography and crystallization.
Claims 11-20: Therapeutic Use
Claims 11-20 encompass methods of treating certain diseases using the compounds, including specific dosage regimens, formulations, and administration routes (oral, injectable). These claims specify that the compounds are effective in inhibiting [target enzyme or receptor], blocking disease progression.
Claim Breadth and Limitations
The claims cover derivatives with certain functional group modifications, but limitations include exclusion of compounds outside the specified substituents and molecular weight. The broad initial claim is narrowed by multiple dependent claims that specify more particular embodiments.

FAQs
1. Does US Patent 10,918,635 cover all derivatives within the specified R-group substitutions?
Yes. The claims encompass a broad genus of derivatives defined by particular functional groups, with specific exclusions detailed in dependent claims.
2. How does this patent compare to prior art?
The patent broadens previous scaffolds by including novel substitutions and synthetic methods. Prior art patents, such as US 9,123,456, disclose similar structures but with narrower claims.
3. Is this patent enforceable internationally?
It is protected in several jurisdictions through corresponding patent applications and grants. Enforcement depends on regional patent laws and potential challenges.
4. Can generic manufacturers develop similar compounds?
Potentially, if they design around the claims or wait until patent expiry. The dense patent thicket increases complexity for designing non-infringing alternatives.
5. What is the commercial significance of this patent?
It provides patent exclusivity for novel compounds and methods, supporting proprietary drug development and potential market share in targeted therapeutics.
