This patent is significant in the pharmaceutical industry, particularly in the development of topical compositions for various medical treatments. Here, we will delve into the scope, claims, and the broader patent landscape surrounding this invention.
Patent Overview
Title and Inventors
The patent, titled "Compositions comprising hyaluronic acid and prostaglandin-synthesis-inhibiting drugs," was invented by Falk et al. and assigned to Nycomed US Inc. and Jagotec AG[2].
Issue Date and Patent Number
The patent was issued on August 11, 1998, and bears the number 5,792,753[2].
Scope of the Invention
Description
The patent describes pharmaceutical compositions that combine hyaluronic acid with prostaglandin-synthesis-inhibiting drugs. These compositions are designed for topical administration and are intended to treat various conditions, including skin disorders and inflammatory diseases. Hyaluronic acid, known for its moisturizing and protective properties, is combined with drugs that inhibit prostaglandin synthesis, which are often used to reduce inflammation and pain[5].
Applications
The compositions covered by this patent can be used in a variety of medical and cosmetic applications. For instance, they can be formulated as creams, gels, or ointments for the treatment of skin conditions such as acne, psoriasis, and dermatitis. The combination of hyaluronic acid and anti-inflammatory drugs enhances the therapeutic efficacy and reduces potential side effects associated with the use of these drugs alone[5].
Claims of the Patent
Independent Claims
The patent includes several independent claims that define the scope of the invention. These claims typically describe the composition, its components, and the method of preparation. For example, Claim 1 might describe a pharmaceutical composition comprising a therapeutically effective amount of a prostaglandin-synthesis-inhibiting drug and hyaluronic acid, along with suitable excipients for topical administration[5].
Dependent Claims
Dependent claims further specify the invention by detailing specific aspects such as the concentration of the active ingredients, the type of prostaglandin-synthesis-inhibiting drugs used, and the method of application. These claims help to narrow down the scope and provide additional protection for specific embodiments of the invention[5].
Patent Landscape
