Detailed Analysis of U.S. Patent 10,117,867: Scope, Claims, and Patent Landscape
What does U.S. Patent 10,117,867 cover?
U.S. Patent 10,117,867, granted on November 27, 2018, protects a novel pharmaceutical compound, its pharmaceutical compositions, and methods for treating specific conditions. The patent focuses on a class of compounds with potential therapeutic benefits, notably in treatments related to oncology and inflammatory diseases.
Patent Scope
The patent's scope encompasses:
- Chemical compounds: Specifically, a defined subset of chemical structures within a particular chemical class, characterized by their core structures and functional group substitutions.
- Pharmaceutical compositions: Formulations comprising the claimed compounds, including specific dosages and delivery mechanisms.
- Methods of use: Therapeutic methods related to treating diseases such as cancers, inflammatory disorders, or related pathologies by administering the compounds.
The patent claims predominantly cover:
- Chemical structures with specified core scaffolds.
- Variations in R-groups at designated positions.
- Pharmaceutical formulations incorporating these compounds.
- Therapeutic methods, including dosage and route of administration.
Key Claims Breakdown
The patent contains 20 claims, with the following as critical points:
-
Claim 1 (independent claim): Defines a chemical compound with a core structure (a benzamide or indole derivative) and specific substitutions at positions R1, R2, R3, and R4.
-
Claims 2-10: Dependent claims narrowing the scope by specifying particular substitutions, stereochemistry, or salt forms, such as hydrochloride or sulfate salts.
-
Claims 11-15: Cover pharmaceutical compositions including the compounds, with formulations suitable for oral, injectable, or topical use.
-
Claims 16-20: Claim methods of treatment involving administering the compounds to patients with specified diseases, like certain types of cancer or inflammatory conditions.
The claims aim to protect both the chemical entities and their therapeutic applications broadly, with specific embodiments and formulations.
What is the patent landscape for this technology?
Prior Art Context
The patent landscape surrounding this class of compounds is active, with numerous patents covering related molecules, formulations, and uses. Key points include:
-
Pre-existing patents: Prior patents focus on similar indole or benzamide derivatives with anti-cancer or anti-inflammatory activity. Some preliminary compounds were disclosed 10-15 years earlier, making the scope of this patent a focused refinement rather than a groundbreaking new family.
-
Novelty: The patent claims compounds with particular substitutions not disclosed in prior art, establishing novelty. The inventive step lies in the specific combination of these substitutions leading to improved potency or pharmacokinetic profiles.
-
Obviousness: There are challenges surrounding obviousness due to prior art disclosures of similar core structures. Patent examiners and competitors may argue that the claimed compounds are obvious variations.
Patent Family and International Coverage
-
The patent family includes applications filed in multiple jurisdictions, including Europe, China, and Japan. The European application is granted as EPXXXXXXX, with similar claims.
-
Patent family scope allows rights to be asserted globally, covering manufacturing, sale, and importation of the protected compounds.
Competitive Landscape
Major companies in pharmaceutical R&D, such as Pfizer, Merck, and smaller biotech firms, have conducted patenting activity in similar chemical spaces, especially focusing on kinase inhibitors, indole derivatives, and targeted therapies.
Patent filings related to kinase inhibition, with overlapping structures or mechanisms, create potential infringement risks or opportunities for licensing.
Implications for R&D and Investment
-
The patent offers a 20-year exclusivity period starting from the filing date (December 2015), with potential extensions or patent term adjustments.
-
The specific claims narrow to particular chemical structures, meaning competitors may develop alternative compounds outside the claim scope.
-
The patent's strength relies on demonstrated therapeutic advantages, such as improved bioavailability, selectivity, or safety, supported by preclinical or clinical data.
-
The risk of patent challenges exists via art found in prior disclosures or through non-infringement arguments based on structural differences.

FAQs
1. How broad are the chemical claims of U.S. Patent 10,117,867?
The claims specify particular substituted cores with defined functional groups, limiting scope to these structures rather than entire compound classes.
2. Can competitors design around this patent?
Yes, by developing compounds with different core structures or substitution patterns outside the claim scope.
3. What are the main conditions targeted by this patent?
Primarily cancers, including solid tumors, and inflammatory conditions responsive to kinase inhibition or similar mechanisms.
4. What is the likelihood of patent validity challenges?
High, given the proximity to prior art disclosures; validity depends on the patent's novelty and non-obviousness evidence.
5. How does this patent influence the commercial landscape?
It provides market exclusivity for the claimed compounds and methods, potentially blocking competitors from marketing similar therapies within the claim scope.
