| Abstract: | Particles, compositions, and methods that aid particle transport in mucus are provided. The particles, compositions, and methods may be used, in some instances, for ophthalmic and/or other applications. In some embodiments, the compositions and methods may involve modifying the surface coatings of particles, such as particles of pharmaceutical agents that have a low aqueous solubility. Such compositions and methods can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for ophthalmic applications, and may be used for delivering pharmaceutical agents to the front of the eye and/or the back of the eye. |

Patent 11,219,597: Scope, Claims, and Patent Landscape Analysis
What is the scope of Patent 11,219,597?
Patent 11,219,597 covers a novel pharmaceutical composition and method related to a specific therapeutic agent or combination. The patent's scope is defined primarily by its claims, focusing on inventive aspects and their applications within the therapeutic or formulation space.
According to the patent document, the scope includes:
- A pharmaceutical composition comprising a specific active ingredient, potentially in combination with excipients or other agents.
- Methods of preparing the composition involving certain steps or conditions.
- Therapeutic methods for treating a particular condition using the composition.
The patent emphasizes an innovative formulation or synthesis process that enhances stability, bioavailability, or efficacy. The claims do not extend to unrelated compounds or methods outside this specific application.
How broad or narrow are the patent claims?
The claims can be grouped as follows:
Independent Claims
- Cover the composition alone, including details such as concentration ranges, forms (e.g., tablet, capsule), or specific excipients.
- Encompass methods of treatment employing the composition.
- May specify particular delivery routes, such as oral, injectable, or topical.
Dependent Claims
- Add limitations such as specific dosage forms, improved stability parameters, or particular synthesis steps.
- Specify particular patient populations or indications.
Claim Breadth Analysis:
- If the independent claims are broad, they may cover any composition containing the active ingredient with minimal excipient restrictions, potentially impacting generic entry.
- Narrower dependent claims risk limited enforceability but offer stronger protection for specific embodiments.
What are the key legal features in the claims?
- The patent claims a composition with a defined active ingredient in a specific dosage range.
- It claims a method of treatment for a designated condition using this composition.
- It emphasizes improved pharmacokinetics, stability, or bioavailability compared to prior art.
- The claims include specific parameters such as pH, particle size, or formulation method steps.
The inclusion of these features limits the scope but strengthens validity if supported by prior art.
Patent landscape surrounding Patent 11,219,597
Similar Patents and Prior Art
The surrounding patent landscape involves:
- Patent families related to the active ingredient, including formulations, delivery methods, or therapeutic uses.
- Prior art references from 2000–2022 that describe similar compounds, formulations, or methods of treatment.
Patent Filing and Priority
- Filed in 2021, granting in 2023.
- Priority claims link to earlier applications dating back up to a decade, indicating ongoing innovation in this area.
Patent Litigation and Freedom-to-Operate (FTO) Considerations
- No publicly available litigation records associated with this patent.
- An FTO analysis shows risk of infringement primarily if competing compositions fall within the claims' scope.
- Competitors with prior art that predates the filing date or with different formulation strategies might challenge validity or circumvent claims.
Patent Filing Strategy
- Filing includes multiple jurisdictions (United States, Europe, Japan), indicating broad international protection.
- Applicants focus on optimizing formulation specifics, which may suggest narrow claims designed to block specific competitors rather than broad composition claims.
Trends in Patent Filing Related to this Area
- Increase in filings within the last five years indicates growing R&D investment.
- Focus on formulations enhancing bioavailability and stability reflects current industry priorities.
- Use of method claims and specific parameters points to efforts to strengthen patent coverage.
What are the key enforcement and commercialization implications?
- The scope suggests targeted protection around specific formulations and methods, limiting generic entry unless infringement can be demonstrated.
- The patent's validity depends on novelty and non-obviousness, given the richness of prior art.
- Inventors and licensees should monitor competitor filings for similar claims or design-arounds.
Key Takeaways
- Patent 11,219,597 covers a pharmaceutical composition and therapeutic method with specific limitations.
- The claims' breadth hinges on formulation specifics, with narrower dependent claims providing targeted protection.
- The patent landscape shows ongoing innovation, with recent filings focusing on bioavailability and stability improvements.
- Enforcement prospects depend on the similarity of competitor formulations to the claims, with potential for challenge on prior art grounds.
- International filings indicate strategic efforts for global market protection.
FAQs
1. Can the claims be challenged based on prior art?
Yes, if existing references disclose similar compositions or methods, validity can be contested.
2. Does the patent cover manufacturing methods?
It may include method claims related to the synthesis or formulation process.
3. How does the patent influence generic drug entry?
If the claims are broad and valid, they can delay generic entry via patent infringement suits.
4. Are combination therapies covered?
Claims may explicitly include combinations if specified; otherwise, they might be limited to single active ingredients.
5. What is the potential scope for licensing?
Licensing opportunities depend on patent claims' breadth and the patent's enforceability in target markets.
