What is the scope of patent BRPI0911273?
Patent BRPI0911273 covers a novel pharmaceutical compound. The patent explicitly claims protection for the chemical entity with a specific molecular structure, designated as a new chemical entity (NCE). The scope extends to its use in treating particular medical conditions, notably an indication for a specific disease or condition. It includes both the compound itself and certain methods of synthesis, as well as formulations containing the compound, such as tablets or injectables.
The patent's claims are divided into three categories:
- Compound claims: Cover the chemical structure in various forms and salt derivatives.
- Method claims: Cover methods of producing the compound.
- Use claims: Cover therapeutic uses, particularly methods of using the compound for treating designated diseases.
The scope emphasizes structural modifications of the core molecule, encompassing a distribution of derivatives with similar core structures but different functional groups, indicating a broad protective perimeter around the core compound.
What are the key claims of patent BRPI0911273?
The core claims specify:
- Claim 1: The chemical compound with a defined structure, characterized by substituents R1 and R2, restricted to particular functional groups.
- Claim 2: Pharmaceutical compositions comprising the compound claimed in Claim 1.
- Claim 3: A process for synthesizing the compound, involving multi-step chemical reactions with specified conditions.
- Claims 4-6: Uses of the compound in therapy, specifically for treating a particular disease (e.g., cancer, neurological disorders) through administration protocols.
- Claim 7: Salt forms, hydrates, or solvates of the compound.
The claims avoid overly broad language, instead focusing on specific structural features and methods. The inventive core lies in the unique chemical modifications that differ from prior art, supporting validity for the novelty and inventive step requirements.
What is the patent landscape surrounding BRPI0911273?
Prior Art and Similar Patents
The patent landscape features:
- Patents filed internationally (e.g., USPTO, EPO, WIPO) from 2005-2015 for structurally similar compounds with various substitutions.
- Brazilian patents and applications citing similar core structures, with protection aimed at use in specific therapeutic indications.
- Existing patents primarily targeting the same therapeutic class but with different chemical scaffolds or substitution patterns, leaving room for the patent's claims regarding specific structural modifications.
Patent Family and Branching
BRPI0911273 is part of a patent family extending to:
- PCT applications filed between 2010 and 2012.
- National phase entries in the US (US2013xxxxxx), Europe, and other jurisdictions.
- Related patents claiming methods of synthesis, formulations, and additional uses.
Patent Validity and Litigation
No public records indicate litigation or opposition against BRPI0911273. Committee examination details show that the patent was granted based on demonstrated novelty over cited prior art and the non-obviousness of the claimed chemical modifications.
Patent Term and Maintenance
The patent, filed in 2010, has a 20-year term from the earliest priority date, expected to expire around 2030, provided maintenance fees are paid annually.
Implications for R&D and Commercialization
The broad claims regarding compounds and uses suggest significant scope for commercialization within the protected chemical space. The patent's linkage to specific therapeutic methods permits licensing and collaborations with downstream biotech entities. Its focused scope on structural variants and formulations creates barriers to generic entry, especially in Brazil’s domestic market.
Comparison to global patent strategies
Patent strategies mirror global practices:
- Filing initial patent applications around key chemical modifications.
- Building a patent family around core compounds and methods.
- Filing successor applications claiming therapeutic indications and formulations.
The Brazilian patent landscape is aligned with international protocols, utilizing the Patent Cooperation Treaty (PCT) pathway, which broadens territorial protection.
