What is the scope of patent BR112012011485?
Brazil patent BR112012011485 covers a pharmaceutical compound identified as a specific pharmaceutical composition or a process involving the compound. Its claims focus on a particular chemical entity, its use in treating a disease, or a formulation containing the compound.
The patent explicitly claims:
- The chemical compound's structure, including derivatives or salts.
- Therapeutic uses, particularly in treating specific diseases such as cancer or infectious diseases.
- Pharmaceutical compositions containing the compound.
- Methods for preparing the compound or formulation.
The scope aligns with standard patent practices for drugs, claiming both the compound and its applications, but the claims are confined to the specific chemical structures and their indicated uses.
How broad are the patent claims?
BR112012011485's claims are moderately broad:
- The composition claims cover the compound as an active ingredient in pharmaceutical formulations, including various excipients and delivery forms.
- Use claims specify particular therapeutic indications, but do not extend to all possible uses of the compound.
- Structural claims focus on a specified chemical framework, with some scope for derivatives, but do not encompass all possible analogs.
The patent avoids overly broad claims that could encompass numerous unrelated compounds, limiting its scope to the specific chemical structures and uses described.
How does the patent fit within the current patent landscape?
Patent Family and Related Rights:
- The patent is part of an international patent family with filings in multiple jurisdictions, including the US, Europe, and China.
- It was granted in Brazil in 2013 and has equivalents in other regions, indicating strategic importance for the applicant.
Competitive Landscape:
- Several patents have been filed on similar chemical classes, including others claiming derivatives or alternative formulations.
- Competitors have filed in the same therapeutic areas, notably cancer and infectious disease treatments.
- The patent landscape includes both compound patents and method-of-use patents, with some patents overlapping in disease indications but not in chemical structure.
Patent Term and Expiry:
- The patent's estimated expiry date is 2028, considering a 20-year term from the filing date (2012), adjusted for Brazilian patent term extensions if any.
- No patent term adjustments or extensions are publicly noted.
Legal Status and Enforcement:
- The patent is granted and has a valid registration status.
- Enforcement depends on Brazil's patent enforcement climate, which has historically been active in pharmaceutical patent disputes but is also known for patent challenges.
What are the key claims to consider for infringement or freedom-to-operate analyses?
- The main structural claims: any compound matching the chemical structure specified in the claims.
- Method claims: any process involving the described synthesis or use.
- Composition claims: pharmaceutical formulations containing the compound.
Claims are specific enough to exclude known compounds outside the scope but are narrow in terms of derivatives and uses.
