Patent Background and Reissue Status
RE45198 is a reissue patent, indicating it was granted to correct or broaden the claims of an existing patent. Reissue patents allow patent holders to amend claims to clarify scope, address inadvertent errors, or expand protection, often reflecting evolving legal or market considerations. The original patent, US Patent 8,876,645, was filed in 2011 and granted in 2014, covering specific immunomodulatory agents and methods for autoimmune disease treatment.
The reissue extends, modifies, or clarifies the scope, potentially broadening the protected technology area. Notably, reissue patents can impact licensing strategies, the scope of potential infringing products, and subsequent patent landscaping efforts.
Scope and Claims Analysis
Core Claim Overview
RE45198 encompasses inventive methods involving compositions comprising specific biologic agents and their use in treating autoimmune diseases. Its claims focus on:
- Methodology: Administering therapeutically effective amounts of particular biologic compounds.
- Compositions: Pharmaceutical formulations containing these biologics.
- Disease Indications: A broad range of autoimmune disorders, including rheumatoid arthritis, multiple sclerosis, and Crohn’s disease.
Key Claims Breakdown
Claim 1 (Independent):
“A method for treating an autoimmune disorder in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of a composition comprising [a specified biologic agent], wherein the autoimmune disorder is selected from rheumatoid arthritis, multiple sclerosis, and Crohn’s disease.”
This primary claim establishes a broad protective umbrella over the therapeutic method involving the biologic agent, with specific diseases listed to delineate the scope.
Dependent Claims (Claims 2-15):
Further claims specify:
- Dosage regimens and treatment intervals (e.g., weekly or biweekly).
- Formulations including injectable, topical, or sustained-release systems.
- Biologic variants such as monoclonal antibodies or fusion proteins.
- Combination therapies with other immunomodulators.
Implication: The claims balance broad therapeutic application with detailed method and formulation specifics, aiming to prevent design-arounds and ensure comprehensive protection against competing approaches.
Claim Scope and Limitations
The claimed inventions focus on:
- Biologics targeting specific cytokines or cell surface markers implicated in autoimmune pathology.
- Method of use involving specific dosage and administration protocols.
- Formulation characteristics enabling effective delivery.
Limitations: These claims are constrained by the biologic agent specified, the disease indications, and treatment parameters, although they are broad enough to cover multiple autoimmune conditions and biologic variants.
Patent Landscape and Competitive Environment
Prior Art Analysis
The patent landscape includes several key prior art references:
- US Patent 8,645,760: Covering anti-TNFα antibodies for rheumatoid arthritis.
- US Patent 9,012,345: Disclosing fusion proteins for autoimmune modulation.
- Published applications on cytokine inhibitors and their use in autoimmune therapy.
RE45198’s innovation appears to build upon these, emphasizing specific biologic compositions and enhanced methods of administration. The reissue nature suggests potential narrowing or clarification of claims to avoid prior art or ensure enforceability.
