Further claims in the patent address:
- Specific concentrations and types of excipients within the composition.
- The use of specific buffer systems (e.g., phosphate buffers).
- The use of specific antimicrobial preservatives (e.g., phenol, m-cresol).
- The use of specific tonicity regulating agents (e.g., sodium chloride, mannitol).
- Pharmaceutical compositions comprising a GLP-1 receptor agonist further comprising a stabilizer.
- The use of the described pharmaceutical composition for the treatment of type 2 diabetes.
- The use of the described pharmaceutical composition for promoting weight loss.
The claims are designed to protect the specific formulation of GLP-1 receptor agonists, aiming to enhance their shelf life, stability upon administration, and overall therapeutic effectiveness. This includes protection against degradation and aggregation of the peptide, which are common challenges in peptide drug formulation.
What is the scope of protection offered by patent BR112014028841?
The scope of protection for BR112014028841 is defined by its claims and the general principles of patent law. The patent protects specific pharmaceutical formulations containing GLP-1 receptor agonists. This means that any party seeking to manufacture, use, or sell a pharmaceutical composition that falls within the literal wording of these claims in Brazil could be infringing the patent.
The protected formulations are characterized by the presence of a specific type of GLP-1 receptor agonist (a modified analog of human GLP-1 (7-37)) and a defined set of excipients, including a specific pH range, a preservative, a tonicity regulator, and water for injection. The patent also covers stabilizers in some formulations.
The patent does not broadly protect all GLP-1 receptor agonists or all possible formulations. Instead, it targets the specific combination of active pharmaceutical ingredient (API) and excipients that constitute the claimed invention. This specificity is crucial for defining the boundaries of infringement.
For example, a generic formulation of a GLP-1 receptor agonist that uses a different peptide analog, a different pH buffering system, or lacks a specific preservative might not fall under the direct claims of this patent. However, the doctrine of equivalents, where applicable in Brazilian patent law, could potentially extend protection to formulations that are not literally claimed but perform substantially the same function in substantially the same way to achieve the same result.
The patent's scope also extends to the therapeutic uses of these specific formulations, such as for treating type 2 diabetes or promoting weight loss. This means that marketing or prescribing these specific formulations for these indications could also be considered infringing activity.
How does patent BR112014028841 compare to other GLP-1 agonist patents?
