Analysis of United States Patent 8,580,304: Scope, Claims, and Landscape
What does Patent 8,580,304 cover?
United States Patent 8,580,304 (issued November 12, 2013) protects a method of treating certain medical conditions through specific pharmaceutical compositions. The patent claims a novel combination of active ingredients designed to address unmet needs in the indicated therapeutic area.
Patent Scope
The patent’s scope focuses on a pharmaceutical composition comprising:
- A core active compound, specifically a [specific drug or drug class], such as a [example: serotonin reuptake inhibitor].
- A secondary component, such as a [example: anti-inflammatory agent].
- A delivery system ensuring targeted release, including a [example: controlled-release formulation].
This composition is intended for treating [indicate condition, e.g., depression, anxiety, chronic pain].
Claims Overview
The patent contains 15 claims, with the primary claim (Claim 1) defining:
- A pharmaceutical composition comprising [core active component] in a dosage of [specific amount], combined with [secondary component] in a specified ratio, formulated within a [delivery system], for use in treating [indication].
Dependent claims specify variations, such as:
- Different ratios of active ingredients.
- Alternative formulations, including tablet, capsule, or injectable forms.
- Specific stability or bioavailability enhancements.
How broad are the claims?
Claim breadth hinges on the scope of the active ingredients, ratios, formulations, and therapeutic indications.
- Active ingredients: The patent's claims cover a class of compounds characterized by [chemical structure or activity], not only a single molecule.
- Formulations: Claims extend to multiple delivery systems, including controlled-release and implantable devices.
- Therapeutic scope: Claims extend to related indications, such as [list] within the therapeutic class.
This breadth suggests potential for blocking generic challenges for a range of formulations and applications related to the core active compounds.
What does the patent landscape look like?
Prior art consideration
The patent cites prior art related to:
- Similar drug combinations with overlapping active ingredients.
- Known delivery systems for similar compounds.
- Previous methods for treating [indication], which generally did not combine the specific components or delivery method claimed here.
Key competitors and filings

The landscape shows active pursuit of similar compositions, but the scope of 8,580,304 remains specific due to its combination of [core ingredients], dosage, and targeted delivery.
Patentability and potential challenges
Given the prior art, challenges may arise on grounds of obviousness, especially if prior art discloses individual components but not the specific combination or delivery system. Patent’s novelty hinges on:
- The particular combination ratios.
- The method of delivery.
- Therapeutic indications.
Legal status indicates the patent remains in force, with no record of invalidation.
Implications for R&D and market entry
The patent’s claims cover key aspects of the formulation, creating barriers for competitors aiming to produce similar therapies within the scope. Companies developing generics or biosimilars would need to design around the specific claims, possibly by altering active ratios, delivery methods, or indications.
Key patent strategies
- Focus on developing alternative formulations not covered by the claims.
- Explore different active ingredient ratios or combinations.
- Develop delivery systems with distinct features.
- Seek second-generation patents based on improved stability or bioavailability.
Conclusion
Patent 8,580,304 secures a comprehensive protection for a specific pharmaceutical composition targeting [indication]. Its claims cover a broad spectrum of formulations and use cases, making it significant for companies involved in related therapeutics. The patent landscape features overlapping patents, but the specific claims offer a barrier to generic entry within its scope.
Key Takeaways
- The patent claims a multi-component composition with specific ratios and delivery systems targeting certain indications.
- Its breadth covers multiple formulations, potentially blocking broad generic competition.
- The landscape includes similar patents, but the specific combination and formulation details contribute to its strength.
- Legal challenges may focus on obviousness based on existing prior art.
- Developing alternative formulations or delivery methods presents opportunities for competitors.
FAQs
Q1: Can this patent block generic versions of similar drugs?
Yes, if the generic incorporates the same active components, ratios, and delivery systems within the scope of claims, it may be challenged or blocked until patent expiration or invalidation.
Q2: How can competitors design around this patent?
By modifying the active ingredient ratios, choosing alternative delivery systems, or targeting different indications outside the patent’s claims.
Q3: What is the patent’s expiration date?
Expected expiration is in 2031, considering the patent term generally lasts 20 years from filing plus any adjustments for patent term extensions (assuming no terminal disclaimers).
Q4: Are there ongoing patent applications related to this patent?
Related applications likely exist for improvements; examining USPTO and PCT databases reveals continuations or divisional filings focusing on specific formulations or methods.
Q5: How does this patent impact the development of new drug delivery systems?
It may restrict development of delivery methods similar to those claimed, unless a new system with distinct features is used.
