Core features:
- Active ingredients include a specific combination of drugs A and B.
- Formulation advances intended to improve absorption rates.
- Application in treating condition X, notably with a focus on oral administration.
- Proprietary manufacturing process that enhances stability under standard storage conditions.
Patent term and validity:
- Filing date: November 2018
- Publication date: November 2019
- Anticipated expiry: November 2038, subject to legal maintenance.
This patent aims to secure exclusivity for a specific drug combination, including the formulation and manufacturing method.
What are the main claims?
The patent's claims define its legal scope, emphasizing formula-specific and process-related elements:
Independent claims:
- A pharmaceutical composition comprising active ingredients A and B in a synergistic ratio, with a specified excipient matrix.
- A method of preparing the composition involving particular mixing and temperature conditions.
Dependent claims:
- Specific weight ratios of ingredients.
- Use of particular excipients such as hydroxypropyl methylcellulose (HPMC).
- Storage conditions maintaining potency stability over six months at room temperature.
- Application of the composition for treating condition X.
Claim strengths:
- Focus on formulation and manufacturing process, which can enable broad protection against infringing products with minor modifications.
- Inclusion of specific excipient combinations and ratios bolsters the scope but may limit flexibility if competitors alter components.
