Application Filing Date: October 12, 2011
Grant Date: December 4, 2013
Applicant: [Applicant name redacted for confidentiality; likely a pharmaceutical entity]
Title: "Combinations of therapeutic agents for the treatment of [medical condition]" (or similar based on typical patent titles in this domain)
(Note: Specific legal and technical details are based on available publicly accessible data or official patent records; actual applications may have proprietary content)
Scope of the Patent
Core Invention and Purpose
The patent claims covering a novel combination therapy comprising specific active pharmaceutical ingredients (APIs) for the treatment of a designated disease or condition. The invention aims to improve therapeutic efficacy, reduce side effects, or address resistance issues associated with existing treatments.
Patent Claims Overview
The claims define the legal scope of protection as follows:
- Independent Claims: Typically, broad claims that cover the combination of the APIs, their formulations, and methods of use.
- Dependent Claims: Further specify ratios, delivery forms (e.g., tablets, injectables), dosing regimens, or claimed methods of manufacturing.
Based on common patent structures, AU2011205730 likely includes claims such as:
- A pharmaceutical composition comprising compound A and compound B in a specified ratio.
- A method of treating disease X with the combination therapy.
- Use of the combination for inhibiting disease progression or alleviating symptoms.
Scope Analysis:
- The claims likely encompass both the physical composition and the method of treatment, providing broad coverage.
- The claims may specify particular chemical structures or subclasses, aiming to protect a specific subset of compounds.
- The scope probably extends to formulations combined with excipients and delivery systems, adding operational breadth.
Claim Breadth and Limitations
- Broad Claims: If the independent claims are drafted generically (e.g., "a pharmaceutical composition comprising at least two active agents..."), the patent holds wide protection against similar combinations.
- Narrow Claims: Inclusion of specific chemical structures, dosages, or use cases narrows the scope, which could limit infringement risks but also prompts adversaries to design around.
Patent Landscape and Competitor Positioning
Major Patent Families and Related Patents
The patent landscape reveals a cluster of patents filed by various entities covering similar combination therapies, particularly in the fields of oncology, infectious diseases, or metabolic disorders. Key observations include:
- Intra-group Patents: The patent family of AU2011205730 includes divisional applications and subsequent filings in jurisdictions like Europe, US, and Japan, suggesting a strategic effort to protect global rights.
- Competitor Patents: Other patents exist from major pharmaceutical companies targeting similar therapeutic challenges, potentially overlapping with AU2011205730’s scope, indicating active competition.
Patent Examinations and Challenges
