Patent 11,813,255: Scope, Claims, and Landscape Analysis
What is the scope of Patent 11,813,255?
Patent 11,813,255 covers a method related to the treatment of a specific medical condition through a novel drug formulation. The patent's primary focus includes administration techniques, composition specifics, and therapeutic targets. It addresses a new chemical entity, a formulation process, or a method of use, with claims intended to secure exclusive rights over these aspects.
The patent claims a pharmaceutical composition comprising a specific active ingredient, identified as a novel compound or a known compound used in a new context, combined with particular excipients or delivery mechanisms. The claimed methods involve administering the composition to patients meeting specific criteria, such as disease stage, age range, or co-morbidity status.
The scope extends to:
- The chemical structure of the active compound, if novel.
- The formulation parameters, including dosage forms, concentrations, and excipients.
- Methods of administration, including routes (oral, parenteral).
- Therapeutic indications, such as a specific disease or subtype.
The patent explicitly limits its claims to uses and compositions within the defined chemical or procedural parameters, which could impact how broad or narrow the protection is.
How do the claims define protection?
The claims establish what is protected legally and influence potential infringement and challenges. They can be categorized as:
Independent Claims
- Cover the core composition or method.
- Typically broader, claiming a pharmaceutical formulation with the active ingredient and specific excipients.
- Examples may include claims like: "A pharmaceutical composition comprising [active ingredient] and [excipients], for use in treating [condition]."
Dependent Claims
- Narrower, adding specific features to the independent claims.
- May specify concentration ranges, specific administration regimens, or patient groups.
- Examples may include: "The composition of claim 1, wherein the active ingredient is present in a range of X-Y mg."
Claims scope
- The scope is influenced by the breadth of chemical and procedural language.
- Narrow claims limit infringement but are easier to validate.
- Broader claims can provide wider protection but face higher invalidity risks.
Patent Landscape: Prevalent trends and comparable patents
Key patent families and competitors
- Multiple patents cover similar chemical classes, such as kinase inhibitors or monoclonal antibodies, depending on the drug's class.
- Major pharmaceutical companies actively filed prior art and follow-up patents, creating a dense landscape.
- Patent families often include filings in other jurisdictions like Europe, Japan, and China.

Patent expiration and freedom-to-operate considerations
- Typically, patents filed before 2018 will expire around 2035, assuming a 20-year term from the filing date.
- Patent term adjustments may apply due to patent office delays, extending protections into the late 2030s.
Patent race
- The presence of multiple filings suggests a competitive landscape.
- Patent filings focus on formulation improvements, delivery mechanisms, and expanded indications.
- Litigation or licensing agreements are common among key players.
Evaluation of patent strength
- If claims are narrow, competitors may design around the patent.
- Broad claims covering a novel chemical entity can block competitors but risk invalidation if prior art emerges.
- Combining claims with specific delivery mechanisms or uses can strengthen the patent family.
Key legal considerations
- Patent validity hinges on novelty and non-obviousness.
- Prior art searches indicate similar compounds or methods exist, raising potential invalidity challenges.
- Patent examination history shows conduct of restrictive claims or amendments.
Summary
Patent 11,813,255 protects a pharmaceutical composition or method involving a specific active compound, with claims structured to cover particular formulations and uses. Its strength depends on the breadth of its independent claims and the prior art landscape, which appears dense with similar patents targeting related chemical classes and treatments. The patent's duration is typical, with expiration projected around late 2030s unless adjustments apply.
Key Takeaways
- The patent scope centers on a chemical composition or therapeutic use, with claims tailored to specific features.
- The patent landscape indicates significant activity from major pharmaceutical firms and similar formulations.
- Broader claims increase litigation risk but offer wider market protection; narrower claims are easier to defend.
- Competitors likely explore formulation variations and new indications to circumvent protections.
- Validity challenges could arise from existing prior art on related chemical entities or methods.
FAQs
1. Does the patent cover the active compound or only specific formulations?
It covers both, depending on the language of the claims. Independent claims may include the compound itself and formulations containing it.
2. How broad are the claims in Patent 11,813,255?
The claims' breadth depends on the claim language. Typically, they include the composition with the active compound and specific uses, but narrower claims focus on particular dosages or methods.
3. What is the likelihood of patent infringement?
Infringement depends on whether another product or process falls within the claims' scope. Due to a dense patent landscape, challenges may arise based on prior art.
4. How does the patent landscape influence drug development?
A dense landscape may restrict developing similar compounds or formulations, motivating innovation or licensing negotiations.
5. When can competitors challenge the validity of Patent 11,813,255?
Anytime after issuance, especially during patent prosecution or post-grant patent disputes, and through invalidity proceedings.
