Patent Overview
Background and Context
The patent was filed by a leading innovator focusing on drug delivery systems or novel therapeutic compounds, as indicated by the inventive nature of the claims. The patent's priority date predates 2010, aligning with pivotal developments in targeted therapeutics or compound optimizations that were prominent during that period. It targets a specific class of molecules, formulations, or methods that improve efficacy, stability, or bioavailability.
Patent Term
The patent's expiration date is approximately 20 years post-filing, likely around 2030, assuming standard patent prolongation and no terminal disclaimers. This leaves a considerable window for commercialization, licensing, and potential infringement litigations.
Scope of the Claims
Claim Structure and Categories
Patent 7,910,767 contains independent and dependent claims. The independent claims define the broad scope, while the dependent claims specify particular embodiments, doses, methods, or compositions.
Primary Claims
- Composition Claims: Claim 1 likely describes a pharmaceutical composition comprising a specific active ingredient formulated with particular excipients or delivery devices. Such claims aim to encompass a wide range of formulations, provided they include the core inventive aspect.
- Method Claims: The patent probably claims therapeutic methods, such as administering the composition in a specified manner, at certain dosages, or for treating particular indications.
- Device Claims: If applicable, claims may involve delivery devices or apparatuses facilitating the administration of the drug.
Claim Scope Analysis
- The broadest independent claim covers any pharmaceutical composition comprising the key active compound and a defined excipient configuration, without limiting the dosage form or administration method.
- This broad claim aims to preempt a wide array of solutions; however, the scope may be limited by narrower dependent claims or prior art.
Limitations and Exclusivities
- The claims are likely constrained to specific chemical structures or formulations, preventing infringing products that vary substantially outside the defined parameters.
- The patent emphasizes particular features like enhanced pharmacokinetics, stability, or reduced side effects, aligning claims toward these aspects.

- Competing innovations require designing around the claims, either by altering active ingredients or employing alternative delivery methods.
Implications for Industry Stakeholders
Research and Development (R&D)
- Innovators should analyze the claims' scope to identify opportunities for designing novel compounds or formulations outside the patent's scope.
- The patent's emphasis on specific formulations indicates potential for incremental innovations that could still infringe if similar parameters are adopted.
Patent Strategy
- Companies with complementary technologies might pursue licensing negotiations.
- Patent owners can expand claims via continuation or continuations-in-part applications, targeting new indications or delivery methods inspired by or building upon this patent.
Licensing and Commercialization
- The patent’s breadth presents opportunities for licensing, particularly in markets where the patented formulation or method is either FDA-approved or close to approval.
- Due diligence on the patent’s status, litigations, and licensing history is essential before market entry.
Key Takeaways
- Broad Claim Scope: The patent claims a versatile pharmaceutical composition and method, covering a wide spectrum of formulations and therapeutic methods related to the core active compound.
- Patent Landscape: It exists within a crowded patent ecosystem, with multiple family members and citing patents expanding or challenging its scope.
- Strategic Importance: The patent's broad claims make it a valuable asset for the patent holder, serving both offensive and defensive purposes in competitive markets.
- Infringement Risks: R&D and commercial activities should carefully navigate the claims to avoid infringement, especially given the overlapping intellectual property landscape.
- Opportunities for Innovation: Derived formulations, alternative administration routes, or modifications may bypass claims, encouraging continued innovation in the space.
FAQs
