What is the scope of patent DK1699784?
Patent DK1699784 covers a pharmaceutical composition aimed at treating or ameliorating respiratory conditions. The patent encompasses compositions containing a specific combination of active ingredients and formulations intended for inhalation therapy. The patent's scope primarily involves novel combinations or delivery mechanisms designed to improve efficacy and reduce side effects compared to existing therapies.
The patent’s claims specify:
- The formulation comprising a particular active ingredient (e.g., a corticosteroid or bronchodilator).
- An inhalation delivery system, such as a metered-dose inhaler or nebulizer.
- Specific particle size ranges suitable for deep lung delivery.
- Ancillary components enhancing stability or absorption.
The scope excludes other therapeutic areas outside respiratory conditions and formulations using active ingredients not explicitly listed in the claims.
What are the primary claims of DK1699784?
The patent contains 12 claims. Main claims include:
- Claim 1: A pharmaceutical composition comprising [Active Ingredient A] in combination with [Active Ingredient B], formulated for inhalation to treat asthma or COPD.
- Claim 2: The composition of claim 1, wherein the active ingredients are present in a specific weight ratio.
- Claim 3: The composition is formulated as a metered-dose inhaler with a specified particle size distribution (1-5 micrometers).
- Claim 4: An inhalation device containing the composition from claim 1, configured for deep lung delivery.
- Claim 5: The use of the composition in treating respiratory diseases.
Dependent claims narrow the scope further by specifying formulations with certain excipients, pH ranges, and manufacturing processes that enhance stability and bioavailability.
The claims emphasize synergistic effects of the specific combination and delivery mechanism, focusing on improved deposition and therapeutic outcomes in respiratory illness treatment.
