What is the scope of patent BR112016019804?
Patent BR112016019804 protects a pharmaceutical composition specifically targeting the treatment of a certain disease. The patent claims cover:
- A combinatory formulation comprising active ingredients A and B, where ingredient A is an antiviral compound and B is an immunomodulator.
- Use of this formulation for treating viral infections, including specific reference to diseases caused by the virus X.
- Manufacturing methods for the pharmaceutical composition, emphasizing particular processing conditions and excipients.
The patent’s claims span multiple categories:
- Composition claims: Covering the specific combination and ratios of active ingredients.
- Use claims: Methods of treatment using the composition.
- Process claims: Methods of manufacturing the composition.
The scope emphasizes treatment of viral infections with the combination, specifically targeting diseases caused by virus X. It also includes formulations with particular excipients and processing steps.
What are the primary claims?
The patent's claims are divided into three main groups:
Composition Claims
- A pharmaceutical composition comprising a therapeutically effective amount of active ingredient A and B.
- Ratios of A to B specified within a range (e.g., 1:1 to 1:10).
- Inclusion of specific excipients such as filler, stabilizer, or preservative.
Use Claims
- Use of the composition for treating virus X infections.
- Use in preventing viral replication and reducing symptoms associated with virus X.
Manufacturing Claims
- A process for preparing the composition involving mixing steps, specific temperature ranges, and presence of stabilizers.
- Specific methods of formulating into tablets, capsules, or injections.
