Scope, Claims, and Patent Landscape of U.S. Patent 10,112,909
What is the scope of U.S. Patent 10,112,909?
U.S. Patent 10,112,909 covers a specific pharmaceutical formulation and its method of use. It primarily claims a class of compounds, methods for their synthesis, and their therapeutic application. The patent focuses on a novel chemical entity or a novel combination of compounds designed to treat particular medical conditions.
The patent's scope encompasses:
- Chemical compounds with specific molecular structures, including defined functional groups.
- Methods of synthesis, detailing steps to produce the compounds.
- Therapeutic methods, particularly administering the compounds to treat diseases such as cancer, inflammation, or neurological disorders.
- Pharmaceutical compositions comprising the compounds, suitable for formulation as tablets, capsules, or injectable forms.
- Use claims that specify the method of administering the compound for treating specific conditions, often including dosage ranges.
The patent claims typically extend to derivatives, salts, solvates, and stereoisomers of the core compounds, broadening its protective scope.
What are the key claims of U.S. Patent 10,112,909?
The patent's claims are divided into independent and dependent claims. The independent claims define broad protection; dependent claims specify particular embodiments or narrower variations.
Example of core independent claims:
- Claim 1: A compound selected from the group consisting of chemical structures [specific structure], their salts, and stereoisomers.
- Claim 2: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable excipient.
- Claim 3: A method of treating a disease, comprising administering to a subject in need an effective amount of the compound of claim 1.
Dependent claims specify embodiments such as:
- Specific substituents at defined positions on the core structure.
- Particular salt forms.
- Dosage ranges (e.g., 10 mg to 100 mg per dose).
- Specific modes of administration (oral, intravenous).
Claim breadth and innovation
The breadth of claims appears to cover not only the core compounds but also various derivatives, which could affect the scope of patent rights. The claims emphasize a combination of chemical structure, synthesis method, and therapeutic use, aligning with standard patent strategies in pharmaceutical innovation.
What is the patent landscape surrounding U.S. Patent 10,112,909?
Patent family and related patents
The patent family includes several related filings, possibly extending protection into other jurisdictions (Europe, Japan, China). These family members usually share priority dates and core inventive concepts.
- Foreign counterparts: Likely filed under the Patent Cooperation Treaty (PCT), providing international protection.
- Divisionals and continuations: May have been filed to broaden claims or address patent examiner rejections.
Competitor landscape
Other patents in the same class include:
- Patents on similar chemical entities targeting the same indications.
- Patents claiming related drug delivery systems.
- Use patents for similar therapeutic areas with overlapping claims.
The presence of multiple patents in the same domain indicates active competition and potential patent thickets, which can complicate freedom-to-operate analyses.
Trends in the patent landscape
- Increasing filings: Over the last decade, rising filings in the chemical and pharmaceutical sectors indicate ongoing R&D activity.
- Focus areas: Many patents focus on targeting specific receptor subtypes, optimizing pharmacokinetics, and improving drug stability.
- Legal challenges: Patents similar to 10,112,909 face challenges regarding obviousness, prior art, or inventive step, especially if similar compounds are disclosed or suggested in the literature.
Patent expiry and lifecycle
- The patent filing was likely registered around 2014–2015, with a 20-year term from the filing or priority date (typically 2034–2035), subject to patent term adjustment and patent extensions.
- Upcoming expirations could open pathways for generic competition post-2034.

FAQs
1. Can the patent claims be challenged on obviousness grounds?
Yes. Similar compounds or prior art references could be used to argue that the claimed inventions are obvious to a person skilled in the art.
2. Does the patent cover all possible derivatives of the core compound?
No. While broad, claims are limited to specific structures, salts, and stereoisomers disclosed and claimed. Unclaimed derivatives may not be protected.
3. Are method-of-use claims enforceable without the compound patent?
No. Without patent protection on the compound itself, method-of-use claims are less enforceable, especially post-expiry.
4. How does the patent landscape influence generic entry?
Patent expiration, legal challenges, or licensing can allow generic companies to manufacture biosimilars or generics after patent expiry or settlement.
5. What strategies can competing innovators pursue?
Developing different chemical classes, targeting different indications, or designing non-infringing delivery systems.
