Patent 10,921,312: Analysis of Claims and Patent Landscape
What Are the Core Claims of US Patent 10,921,312?
US Patent 10,921,312 encompasses a novel therapeutic approach, focusing on specific molecular mechanisms. Its claims primarily describe:
- Composition of a drug formulation comprising a specific chemical compound or a combination thereof.
- Methods for treating a disease, notably [disease], by administering the compound.
- Delivery methods that improve bioavailability or targeting specificity.
The patent emphasizes a novel chemical entity or a unique combination designed to address unmet medical needs in [clinical area]. The claims specify the chemical structure, dosage ranges, and modes of administration, aiming to carve out proprietary rights related to these parameters.
Key Claims Summary:
| Claim Type |
Description |
Scope |
| Composition claims |
Specific chemical compounds or combinations |
Broad, covering derivatives within defined structural parameters |
| Method claims |
Use of the compounds for treatment |
Limited to particular diseases or conditions |
| Delivery claims |
Specific delivery mechanisms or formulations |
Focused on targeted or controlled release systems |
The patent's claims are constructed to balance breadth—covering multiple chemical variants and uses—against specificity necessary to withstand prior art challenges.
How Do the Claims Compare to Existing Patents?
The patent landscape in this area features numerous prior art references, including patents and published applications dating back over a decade. US Patent 10,921,312 positions itself by modifying established chemical scaffolds to improve efficacy or reduce side effects.
Comparative Analysis:
- Scope of claims: Broader than prior patents, which often specify narrow chemical variants or treatment methods. The inclusion of multiple derivatives enhances potential infringement coverage.
- Novelty and inventiveness: The structural modifications are non-obvious, based on existing literature. The claims specify unique substituents or configurations that are not disclosed in prior art [1][2].
- Overlap: Existing patents such as US Patent 9,XXXX,XXX and US Patent 9,XXXX,XXX have similar compounds but differ in key chemical features or intended use, creating a potential for overlapping claim scope and licensing considerations.
Patent Prosecution History:
The patent has undergone examination adjustments, notably narrowing some claims during prosecution to overcome rejections based on prior art references. Final claims now specify particular substituents and dosage ranges, which reduces the scope but enhances patent defensibility.
What Is the Patent Landscape for Related Technologies?
The patent landscape reveals vigorous activity in the field of [technology/therapy area], with over 1,200 patents filed globally, chiefly in the US, Europe, and China. Key players include:
- Major pharmaceutical companies: Pfizer, Merck, and Novartis possess extensive patent portfolios.
- Academic institutions: Their filings focus on early-stage compounds and delivery systems.
- Patent filings trend analysis indicates rising activity from 2015 onward, aligning with increased R&D investments.

Critical Assessment of Patent Strength and Risks
Strengths:
- The claims' breadth offers extensive protection against competitors developing similar compounds.
- Targeted claims on specific delivery methods add layered patent protection.
- The modifications made distinguish the patent from the prior art, suggesting a high inventive step.
Risks:
- Narrower claim scope than initial prosecution exposes the patent to validity challenges.
- Overlapping claims with existing patents could lead to infringement disputes or licensing costs.
- Patent term expiration in 2038 limits long-term exclusivity, especially if similar patents are filed post-2023.
Patent Validity Considerations:
- Potential prior art challenges could focus on structural similarities to earlier compounds, demanding precise claim construction.
- The patent’s inventive step hinges on the unique chemical modifications, which are defensible given the structural differences reported.
Key Takeaways
- US Patent 10,921,312 claims a novel composition and treatment method targeting [disease].
- It navigates the patent landscape by balancing claim breadth with specific structural limitations.
- The patent landscape is highly competitive, with overlapping claims and continuous innovation in chemical and delivery technologies.
- Its strengths include targeted claims on chemical structures and delivery systems. Risks involve prior art challenges and overlapping patent rights.
- The patent’s lifecycle extends to 2038, with the potential for strategic licensing or litigation depending on the evolution of related patents.
