United States Patent 8,945,612: A Detailed Analysis of Scope, Claims, and Patent Landscape
Introduction
United States Patent 8,945,612, titled "Capsules Containing High Doses of Levodopa for Pulmonary Use," is a significant patent in the field of pharmaceuticals, particularly for the treatment of Parkinson's disease. This patent, granted to Civitas Therapeutics, Inc., introduces a novel inhalable powder composition that enhances the delivery of levodopa, a crucial medication for managing Parkinson's symptoms.
Background of the Invention
Parkinson's disease is a debilitating neurological disorder characterized by the death of dopamine-producing neurons in the brain. Levodopa, combined with carbidopa, is the most commonly used treatment to alleviate symptoms such as tremors, slowness in movement, and difficulty walking. However, traditional oral administration of levodopa has several limitations, including variable absorption rates and side effects. The invention described in this patent aims to overcome these challenges by developing an inhalable form of levodopa[1].
Scope of the Patent
The patent covers a specific inhalable powder composition designed for pulmonary delivery. The composition includes:
- Levodopa: At least 75% by weight of the composition.
- Dipalmitoylphosphatidylcholine (DPPC): A phospholipid that helps in forming stable liposomes.
- A Salt: Characterized by a working density of less than about 100 g/L, which enhances the stability and dispersibility of the powder[1].
This formulation is encapsulated in a way that ensures efficient delivery of levodopa directly to the lungs, bypassing gastrointestinal absorption issues.
Claims of the Patent
The patent includes several claims that define the scope of the invention:
- Composition Claims: These specify the exact percentages and types of components in the inhalable powder, including levodopa, DPPC, and the salt.
- Method Claims: These describe the methods for preparing the inhalable powder composition and the process of administering it through inhalation.
- Apparatus Claims: These cover the specific devices or capsules designed to deliver the inhalable powder effectively[1].
