Introduction
United States Patent 10,996,208, held by Radius Health, Inc., is a critical patent in the field of pharmaceuticals, particularly for the treatment of osteoporosis. This patent is associated with the drug abaloparatide, a bone-building agent used for postmenopausal women. Here, we will delve into the scope and claims of this patent, as well as the broader patent landscape.
Background of the Patent
The patent 10,996,208 is part of a series of patents related to abaloparatide, which was approved by the FDA as Tymlos®. This drug is the first new anabolic agent for treating osteoporosis in postmenopausal women in over a decade[1].
Claim Scope
Definition of Claims
The claims of a patent are the most critical part as they define the scope of the invention. For U.S. Patent 10,996,208, the claims are directed towards formulated abaloparatide drug products with specific features.
Key Claims
- Claims 14 and 15: These claims are particularly significant as they pertain to formulated abaloparatide drug products that have been determined suitable for administration by detecting and quantifying the presence of beta-Asp10 impurity at certain levels. The court has interpreted these claims to not be limited to a particular method of detection and quantification, emphasizing the suitability of the drug product rather than the method used[2].
