Design is a form of intellectual property right concerned with the visual appearance of articles which have commercial or industrial use. The visual form of the product is what is protected rather than the product itself. The visual features protected are the shape, configuration, pattern or ornamentation. A design infringement is where a person infringes a registered design during the period of registration. The definition of a design infringement differs in each jurisdiction but typically encompasses the purported use and make of the design, as well as if the design is imported or sold during registration. To understand if a person has infringed the monopoly of the registered design, the design is assessed under each jurisdiction's provisions. The infringement is of the visual appearance of the manufactured product rather than the function of the product, which is covered under patents. Often infringement decisions are more focused on the similarities between the two designs, rather than the differences.

Flutazolam is a drug which is a benzodiazepine derivative. It was invented in Japan, and this is the main country in which it has been used medically. It has sedative, muscle relaxant, anticonvulsant, and anxiolytic effects similar to those produced by other benzodiazepine derivatives, and though it is around the same potency as diazepam, it produces a more marked sedation and impaired coordination. It is indicated for the treatment of insomnia. Its major active metabolite is n-desalkylflurazepam, also known as norflurazepam, which is also a principal metabolite of flurazepam. While flutazolam has a very short half-life of only 3.5 hours, n-desalkylflurazepam has a long half-life of between 47–100 hours.
