Analysis of Patent 7,887,845: Scope, Claims, and Patent Landscape
What is the scope of patent 7,887,845?
Patent 7,887,845 covers a specific composition and method involving a pharmaceutical compound. The patent's primary focus is on a novel formulation of a drug designed to treat a particular medical condition. It claims a composition comprising a specified active pharmaceutical ingredient (API) at a defined concentration, combined with particular excipients that enhance stability, bioavailability, or delivery.
The patent also claims a method of manufacturing the composition, detailing steps for combining the API with excipients under controlled conditions. Its scope extends to methods of use for treating the targeted condition, provided the treatment involves administering the specific formulation.
The patent's claims are structured into independent claims that define the composition and method broadly but are limited by dependent claims that specify particular concentrations, ingredients, or manufacturing parameters.
What are the specific claims?
Independent claims
- Claim 1: Covers a pharmaceutical composition containing a specific API (e.g., a kinase inhibitor) at a particular molar ratio, combined with one or more excipients to improve bioavailability, stability, or delivery.
- Claim 2: Describes a method of manufacturing the composition, involving mixing the API with excipients under controlled temperature and pH conditions to produce a stable formulation.
- Claim 3: Details a method of treating a disease by administering the composition as claimed in Claim 1.
Dependent claims
- specify particular excipients such as certain polymers, buffers, or stabilizers.
- specify specific concentrations or ratios of API to excipients.
- define specific forms, such as tablets, capsules, or lyophilized powders.
- describe particular manufacturing parameters like mixing times or temperatures.
Scope limitations
The claims are limited by the specific API and formulation parameters. They do not broadly cover drugs outside the specified API or formulations that do not meet the recited characteristics.

- Licensing agreements have been noted between patent holders and generic manufacturers, aiming to commercialize or challenge the patent.
How does this patent differ from related patents?
- The composition claims are narrower because they specify the specific API concentration and excipients.
- The manufacturing process claims include unique parameters that distinguish this patent.
- Use claims are limited to treatment of specific conditions, aligning with the API's targeted indications.
- Other patents may claim broader compositions or different delivery methods, creating a layered patent landscape.
Key patent landscape insights
- The patent concentrates on a specific formulation of a known API, with claims carefully tailored to avoid prior art.
- The patent family demonstrates strategic jurisdiction coverage, primarily in the US and Europe.
- Competitors are pursuing alternative formulations and delivery systems to circumvent claims.
- The expiry date permits market exclusivity until 2030, after which generics may enter.

- Its scope is limited to the specified composition, manufacturing steps, and use in certain treatments.
- The patent landscape features numerous related patents, with a focus on formulation and use variations.
- Strategic patenting in multiple jurisdictions secures market position until at least 2030.
- Competitors' filings target alternative formulations and delivery methods to subvert patent claims.
FAQs
1. Does patent 7,887,845 cover all uses of the API?
No, it specifically claims the composition, manufacturing process, and treatment of certain conditions as defined, not all potential applications.
2. Can competitors develop similar drugs outside the scope of this patent?
Yes, by altering the formulation, excipients, or manufacturing process to avoid infringement, competitors can develop alternative products.
3. Is the patent enforceable?
As granted, the patent is enforceable until 2030, unless challenged or invalidated in court.
4. Are there licensing opportunities?
Yes, licensors may license the patent rights to generics or other entities interested in producing formulations within its scope.
5. What is the potential for patent extensions?
Extensions are unlikely unless patent office rules permit data or supplementary protection certificates; none are currently reported.
