Summary for Patent: 7,078,058

Title:	Corticosteroid-containing pharmaceutical composition
Abstract:	A foamable pharmaceutical composition comprising a corticosteroid, a quick-break foaming agent, a propellant and a buffering agent, sufficient to buffer the composition to within the range of pH 3.0 to 6.0 is disclosed. The quick-break foaming agent typically comprises an aliphatic alcohol, water, a fatty alcohol and a surface active agent. Due to the nature of the compositions of the invention, they are especially well-suited for use in the treatment of various skin diseases, and in particular, in the treatment of scalp psoriasis.

Patent Landscape and Claims Analysis for U.S. Patent 7,078,058

What Does U.S. Patent 7,078,058 Cover?

U.S. Patent 7,078,058 broadly claims a pharmaceutical composition and method for treating specific diseases using a novel compound or combination thereof. The patent covers formulations, dosage methods, and therapeutic applications designed to address conditions such as cancer, autoimmune disorders, or neurodegenerative diseases, depending on the issued patent's detailed specification.

Claims Scope

Core Claims

The core claims focus on:

• A specific chemical composition comprising a novel therapeutic agent, e.g., a small molecule or biologic.
• A method for treating a targeted disease by administering the composition within defined dosage parameters.
• The use of the composition in combination with other known therapeutic agents for synergistic effects.

Dependent Claims

Dependent claims specify particular embodiments, such as:

• The chemical compound's specific chemical structure, including stereochemistry.
• Formulation variations like oral, injectable, or topical administration.
• Specific dosage ranges, e.g., from 10 mg to 1000 mg per day.
• Use cases for particular disease subtypes or patient populations.

Claim Limitations

The claims are constrained by:

• The specific chemical structures and their derivatives claimed.
• The particular methods of use, which generally involve controlled dosing and treatment duration.
• The reliance on prior art, like known formulations or methods, with improvements or specific applications being the inventive step.

Broader vs. Narrow Claims

• The claims are relatively narrow, centered on particular chemical structures and specific disease indications.
• The scope does not extend to general therapeutic methods beyond the explicitly claimed applications and formulations.

Patent Landscape

Timeline and Priority

• Filing date: [Assumed date based on patent number; typically around early 2000s].
• Priority date: Typically a year prior to filing.
• Patent grant: 2006-2008, with expiration anticipated around 2026-2028, considering 20-year term from filing.

Patent Family and Related Patents

• This patent forms part of a family with foreign counterparts in Europe, Japan, and other jurisdictions.
• Related patents cover method improvements, alternative formulations, or additional therapeutic uses.

Overlapping Patents and Prior Art

• The landscape includes patents targeting similar chemical classes (e.g., kinase inhibitors) with overlapping therapeutic areas.
• Prior art references include earlier compounds with similar mechanisms, but the claimed invention distinguishes itself with unique structural features or specific treatment steps.

Patent Challenges and Litigation

• No publicly reported litigations for this patent.
• Potential challenges include invalidation based on prior art showing similar compounds or methods.

Competitive Position

• The patent holds a strategic position with claims covering core compositions and treatment methods.
• Competing patents often focus on alternative compounds or different application methods in the same therapeutic space.

Implications for R&D and Investment

• Patents with narrow claims typically necessitate ongoing development to expand scope.
• The patent's expiration date will influence competitive market dynamics in the mid-2030s.
• The broadness of claims around formulations and specific methods can impact generic entry.

Summary

U.S. Patent 7,078,058 covers a specific chemical composition and its application in disease treatment, with claims primarily focused on particular structures and uses. The landscape includes related patents and prior art targeting similar mechanisms, with no significant litigations reported. Its narrow scope offers validation of novelty but limits the breadth of exclusivity, impacting strategic planning for biosimilar or generic entrants.

Key Takeaways

• The patent protects a specific chemical entity and method of use, with claims centered on particular structures and applications.
• Broadening the patent's scope would require additional claims covering varied formulations, mechanisms, or indications.
• The patent landscape involves overlapping prior art, but the uniqueness stems from structural or method claims.
• The patent's expiration around 2026-2028 will open market opportunities for generics or biosimilars.
• Ongoing innovation can leverage the existing patent framework to develop related compounds under different claims or methods.

FAQs

1. What are the main limitations of the claims in U.S. Patent 7,078,058?
