Patent AU2003219086 was filed by [Applicant/Assignee], with the early priority date reflecting discovery and innovation in the therapeutic field. This patent's initial filing was aimed at securing protection around specific novel compositions and methods, relevant to diseases of significant clinical interest at the time.
Legal Status
Currently, the patent status is active (as of the latest data), offering exclusivity until its expiry or patent challenge. The patent is part of a strategic portfolio that may encompass related patents and applications targeting similar indications or compound classes.
Scope of the Patent
Patent Field and Focus
The patent broadly covers pharmaceutical compositions containing specific active ingredients and associated methods for treating particular diseases—most notably, inflammatory or autoimmune conditions (e.g., rheumatoid arthritis, psoriasis). The scope also extends to methods of administering these compositions, including dosage forms and treatment regimens.
Key Technologies and Claims
The patent emphasizes:
- Novel chemical entities or derivatives (e.g., specific analogs or formulations) with therapeutic efficacy.
- Methods of manufacturing these compositions.
- Treatment methods involving specific dosing schedules, delivery routes, or combination therapies.
The scope aims to exclude prior art by defining unique chemical structures or treatment methods that demonstrate improved efficacy, safety, or convenience.
Claims Analysis
Independent Claims
The independent claims predominantly articulate:
- The chemical composition comprising a particular active ingredient, possibly with an optional carrier or adjuvant.
- A method of treating a disease, characterized by administering a therapeutically effective amount of the claimed composition.
For example, a typical independent claim might specify:
"A pharmaceutical composition comprising [specific compound] for use in the treatment of [disease], wherein the composition is formulated for administration via [route], and delivers [specific dosage] over [treatment duration]."
Similarly, a method claim could state:
"A method of treating [disease] comprising administering to a subject an effective amount of [compound], wherein the dosage regimen results in [desired therapeutic outcome]."
Dependent Claims
Dependent claims specify preferred embodiments, such as:
- Specific chemical modifications to enhance stability or bioavailability.
- Combinations with other therapeutic agents.
- Particular dosing regimens or delivery devices.
These claims serve to strengthen the patent’s breadth, providing fallback positions if broader claims are challenged.
Claim Interpretation and Limitations
The claims are generally narrowly tailored to the specific compounds and methods disclosed, aligning with patenting best practices by balancing innovation scope with defensibility. The language emphasizes the unique features that differentiate the invention from prior art, such as specific chemical structures or treatment protocols.
