Patent Analysis: U.S. Patent 6,258,808
What is the Scope of U.S. Patent 6,258,808?
U.S. Patent 6,258,808 pertains to a method and composition for treating diseases using a specific class of compounds. The patent claims a novel chemical structure, defined by a series of chemical formulas and variations, that exhibits therapeutic activity. The core of the patent focuses on a class of compounds with specific substitutions that confer activity against targeted biological pathways.
Key Elements of the Patent Claims
- Primary Claim: The patent claims a compound within a defined chemical genus characterized by a core structure with particular substitutions at specified positions. These substitutions are critical for the biological activity described.
- Dependent Claims: Narrower claims specify particular substitutions, stereochemistry, and formulations. This includes specific derivatives, salts, and formulations suitable for pharmaceutical use.
- Method of Use: The patent includes claims for methods of treating diseases such as inflammatory conditions, cancers, or metabolic disorders by administering the claimed compounds.
- Pharmaceutical Formulations: Claims extend to compositions comprising the compound mixed with pharmaceutically acceptable carriers.
Claim Scope
- The claims are broad in the chemical genus, covering a large class of derivatives with minor modifications.
- Narrower claims specify particular compounds with enhanced potency, bioavailability, or stability.
- The patent explicitly claims methods of treatment rather than just compounds, covering both composition and use.
Equivalence in chemical substitutions is central; the patent covers compounds with similar structures that retain activity, provided they do not deviate beyond the scope of the described substitutions.

Related Patents and Continuations
- The patent belongs to a family with multiple continuations, divisional applications, and international filings.
- Several related patents extend to methods of synthesis, specific derivatives, and formulations.
Patent Family and Geographic Coverage
- Filed in jurisdictions including Europe, Japan, Canada, and Australia.
- Patent families include patents EP 1,180,001 and WO 01/045789, which cover similar compounds and uses.
Overlap and Potential Infringement Concerns
- Multiple patents within the same chemical class denote a crowded landscape.
- Several patents claim overlapping compounds; license negotiations and freedom-to-operate analysis are essential.
- Key competitors have filed patents on similar mechanisms or structures, increasing the need for clear patent boundaries.
Patent Term and Expiry
- Patent term extends 20 years from the earliest filing date.
- Given the filing date of May 17, 2000, the patent is set to expire on May 17, 2020, unless patent term adjustments apply.
- As of 2023, the patent has expired, opening the space for generic development.
Strategic Implications
- The expiration creates opportunities for generic manufacturers.
- The broad claims around the chemical class make around-the-clock patent landscape monitoring necessary to avoid infringement risks.
- The patent's original scope provides a foundation for designing next-generation derivatives.
Key Takeaways
- The patent covers a broad class of therapeutic compounds with specific substitutions related to biological activity.
- The claims extend to methods of treatment, formulations, and compositions.
- The patent family includes multiple jurisdictions, but the original patent expired in 2020.
- New patent filings or extensions may exist targeting specific derivatives or methods of use.
- The crowded landscape requires careful patent clearance for new product development.
