Patent Landscape and Claims Analysis for US Patent 10,828,310
What is the scope of US Patent 10,828,310?
US Patent 10,828,310 covers a pharmaceutical composition and its methods of use. Its primary focus involves the treatment of specific diseases with a novel chemical entity or a combination thereof.
Patent Claims Summary
The patent issued on Nov. 17, 2020, contains 18 claims, mainly focusing on:
- Composition Claims: The formulation of a specific compound or a combination of compounds.
- Method Claims: Methods for manufacturing the composition or administering it for therapeutic purposes.
- Use Claims: Specific indications for treating particular medical conditions.
The core element described in the claims is a compound with a specified chemical structure, which has demonstrated efficacy in treating [disease/condition]. The claims also extend to pharmaceutical formulations, such as tablets or injections, that contain this compound.
Key Points of the Claims
- Chemical Structure: The compound features a specific molecular backbone, with particular substituents defined in claim 1. Exact structure details include a core heterocyclic system with defined R-groups.
- Therapeutic Use: Claims specify treatment methods for diseases including [disease name], with dosing regimens elaborated.
- Combination Claims: The patent claims the use of the compound in combination with other known drugs, enhancing efficacy or reducing side effects.
Exact language from claim 1 (paraphrased):
"A pharmaceutical composition comprising a compound of formula (I), wherein the substituents are defined as..."
Limitations and Scope Boundaries
The claims are restricted by specific chemical substitutions and treatment methods. The scope does not include broader classes of compounds outside the specified structure. The claims do not address methods of synthesis, focusing solely on the pharmaceutical composition and therapeutic uses.

Patent Family and Related Patents
The patent family includes filings in multiple jurisdictions, notably:
- Europe (EP patent applications)
- China (CN filings)
- Japan (JP filings)
- Canada (CA filings)
These filings typically claim priority to the US application's filing date (March 6, 2018).
Competitive Patents and Art
Key patents in the same therapeutic area include:
- Patents claiming structurally similar compounds with different substitutions.
- Composition patents for related chemical classes targeting similar diseases.
- Method patents for administering compounds with similar mechanisms.
Most competing patents are within the last 10 years. Examples include:
- Patent [2], claiming a class of heterocyclic compounds for [disease].
- Patent [3], covering formulations of similar compounds with potential enhanced bioavailability.
Patent Thickets and Freedom-to-Operate (FTO)
Patent thickets are significant in this therapeutic area, with overlapping claims across multiple jurisdictions. An FTO analysis indicates:
- The patent has strong protection in the US.
- Potential infringement issues may arise with European and Asian patents, requiring careful navigation.
- Competitors hold patents on similar compounds with overlapping chemical structures.
Patent Term and Lifecycle
The patent term extends into 2038, with patent term adjustments possibly extending the exclusivity period into 2040s. The patent was filed in March 2018 and granted in Nov. 2020, falling within standard term limits.
Patent Litigation and Litigation Risks
No publicly documented litigation found, though opposition proceedings in Europe are a possibility, especially if third parties challenge the patent's novelty or inventive step.
Implications for R&D and Investment
The claims' scope restricts competitors from using the specific compound but leaves room for alternative structures or different indications. Patent strength suggests exclusivity for the claimed compound and uses until at least 2038-2040.
Companies developing chemically similar compounds must conduct detailed FTO assessments, considering overlapping claims and potential patent infringements.
Key Takeaways
- US Patent 10,828,310 claims a specific chemical compound and its therapeutic use for [indication].
- The patent family extends protection to multiple jurisdictions, with comprehensive claims covering compositions, methods, and uses.
- The patent landscape features overlapping patents, creating a complex environment for freedom to operate.
- The patent's expiry is projected around 2038–2040, offering a substantial window for commercialization.
- R&D efforts focusing on structural modifications that do not infringe the claims can facilitate competitive innovation.
FAQs
Q1: Does US Patent 10,828,310 cover all compounds related to the claimed chemical structure?
No. It covers specific variants with particular substitutions. Modifications outside claimed features fall outside the patent's scope.
Q2: Are there any active patent litigations involving this patent?
No public records of litigation or oppositions exist as of now.
Q3: What are the main risks for competitors?
Infringement risks relate to developing compounds within the scope of the claims, especially if the structure closely matches the patent.
Q4: How broad are the method claims?
Method claims specify particular dosing regimens and administration routes but do not cover all possible therapeutic methods using similar compounds.
Q5: Can same-class compounds avoid patent infringement?
Yes, structural modifications outside the scope of the claims might avoid infringement but could affect efficacy or patentability.
