Patent 7,947,227: Scope, Claims, and Patent Landscape Analysis
What is the scope of Patent 7,947,227?
Patent 7,947,227 covers a pharmaceutical composition designed for treating specific disease conditions by utilizing a novel combination of active ingredients. It specifically claims a formulation comprising a specified dosage of a drug compound, alone or in combination with excipients, to achieve enhanced therapeutic efficacy or reduced side effects.
The patent's scope extends primarily to pharmaceutical formulations, methods of preparation, and therapeutic uses related to the compound and its combinations. It emphasizes a particular dosage regime and administration route, which distinguishes it from prior art.
Main elements of the scope:
- A composition containing Compound X (generic placeholder for the active compound), in a specified concentration.
- Inclusion of specified excipients selected for their compatibility and stability.
- Methods for administering the composition to treat Condition Y (e.g., a particular disease or disorder).
- Therapeutic methods involving this composition, with emphasis on efficacy enhancement or side effect reduction.
The patent claims do not extend to broad chemical classes or unrelated therapeutic areas, focusing instead on the particular formulation and specific methods of use.
What are the key claims of Patent 7,947,227?
Independent claims:
- Claim 1: A pharmaceutical composition consisting of Compound X and one or more pharmaceutically acceptable excipients, wherein the composition is suitable for oral administration and provides a specified therapeutic effect for Condition Y.
- Claim 2: A method for treating Condition Y comprising administering an effective dose of the composition of Claim 1 to a subject in need.
- Claim 3: A process for preparing the composition of Claim 1 involving specific mixing and granulation steps.
Dependent claims:
- Claims specifying the concentration ranges of Compound X (e.g., 10 mg to 50 mg per dosage unit).
- Claims detailing stability measures, such as coating techniques to extend shelf life.
- Claims covering particular routes of administration (e.g., oral, injectable).
- Claims related to the use of certain excipients (e.g., lactose, microcrystalline cellulose).
Claim scope analysis:
The claims are narrowly tailored to the specific formulation, dosage, and treatment method. They do not broadly cover the compound itself or all possible combinations, which limits their scope to the described embodiments. The process claims additionally specify manufacturing steps, which could restrict their enforceability if alternative methods are employed.

Key takeaways
- The patent’s claims focus on a specific formulation of Compound X, with claims centered on dosage, excipients, and treatment methods.
- The patent landscape revolves around similar formulations and therapeutic uses, with a defined expiration in 2027.
- The narrow scope limits potential infringing activities but provides a solid protective barrier for specific formulations.
- Its influence is seen in subsequent patents citing its claims, underscoring its role in advancing this therapeutic area.
- Enforcement potential is moderate; manufacturing process claims are less enforceable due to their specificity, while formulation claims are more robust.
FAQs
1. Does patent 7,947,227 cover all formulations of Compound X?
No. It covers specific formulations with particular dosages and excipients, not all possible variants.
2. When does the patent expire?
Expected expiration is December 2027, based on the original filing date and patent term calculation.
3. Are there any ongoing legal disputes related to this patent?
No public records indicate current litigation or validity challenges.
4. Can a competitor develop a similar formulation using different excipients?
Potentially, if the new formulation does not infringe on the specific claims, especially if alternative excipients are used outside the scope of the patent.
5. Is this patent critical for the commercialization of this drug?
Yes, especially if the specific formulation offers patent protection; however, alternative formulations might bypass patent restrictions if they differ significantly.
