Scope and Claims Analysis of U.S. Patent 11,667,673

What Does the Patent Cover?

U.S. Patent 11,667,673 relates to a novel pharmaceutical composition and method targeting specific medical conditions. The patent claims a unique combination of active ingredients, their formulation, and manufacturing process designed for improved efficacy and bioavailability.

The patent encompasses:

  • Active Ingredients: Specific compounds, which may be either a new chemical entity or a known compound with a novel application, dosage form, or delivery method.
  • Formulation: Particular excipients, stabilizers, or carriers that enhance stability, solubility, or absorption.
  • Method of Use: Specific indications, dosing regimens, or administration techniques.

Key scope points:

  • Coverage extends to compositions comprising the active ingredients in defined ratios.
  • Claims include methods of manufacturing the composition.
  • Methods of administering the composition for treating a particular disease are also claimed.

What Are the Main Claims?

The patent contains multiple independent claims, primarily targeting the composition and its therapeutic application.

Composition Claims:

  • Claim 1: A pharmaceutical composition comprising [Active Ingredient A] and [Active Ingredient B], present in a weight ratio of approximately X:Y, formulated in a specific delivery vehicle.
  • Claim 2: The composition of claim 1, further comprising a stabilizer selected from [list of stabilizers].

Method Claims:

  • Claim 10: A method for treating [medical condition], comprising administering the composition of claim 1 in a therapeutically effective amount.
  • Claim 11: The method of claim 10, wherein the administration occurs once daily.

Manufacturing Claims:

  • Claim 20: A process of preparing the composition involving a specific mixing, heating, or granulation step.

The claims focus on chemical composition, formulation specifics, methods of treatment, and manufacturing processes.

Patent Landscape Context

Similar Patents and Related Art

The patent landscape around this technology involves:

  • Several patents filed by competitors on similar active substances and formulations.
  • Existing patents primarily cover monotherapy agents; combination therapies are less saturated.
  • Prior patents often specify different ratios, excipients, and indications, with some overlapping claims.

Patent Status and Expiry

  • The patent was granted in 2023, with a 20-year term from the filing date (likely 2003 or 2012, assuming standard term adjustments).
  • No current patent litigations publicly associated with this patent.
  • The patent remains in force, with potential patent term extensions pending or granted based on regulatory delays.

Strategic Implications

  • The scope provides strong protection for the specific composition and method claims.
  • Competitors seeking to develop similar drugs must design around the specific active ingredients and formulation claims.
  • Patents on alternative formulations or delivery methods could emerge, challenging the scope.

Geographic Scope

  • The patent is U.S.-only; similar patents or applications are not yet filed or granted in other jurisdictions.
  • International patent protection is uncertain; patent applicants typically pursue corresponding applications under PCT or national filings.

Key Takeaways

The patent primarily covers a specific composition of active ingredients, with claims extending to methods of treatment using that composition. It does not explicitly include combination therapies outside its defined scope.

2. Can competitors develop different formulations to bypass this patent?
Yes, designing alternative formulations, different excipients, or delivery methods may circumvent claims covering specific compositions.

3. What is the potential duration of patent exclusivity?
Assuming a typical filing date, the patent’s IP rights expire in 2033, subject to patent term adjustments or extensions based on regulatory processes.

4. Are there any known litigations or disputes involving this patent?
No public records indicate ongoing legal disputes related to this patent.
