United States Patent 9,687,611: A Detailed Analysis of Scope, Claims, and Patent Landscape
Introduction
The United States Patent 9,687,611, titled "Injection device with torsion spring and rotatable display," is a significant patent in the field of medical devices, particularly injection devices. This patent, assigned to Novo Nordisk A/S, covers innovative designs and mechanisms for injection devices, which are crucial for the administration of various medications.
Background and Context
Injection devices are essential in modern healthcare, especially for patients requiring regular doses of medications such as insulin, growth hormones, or other therapeutic agents. The design and functionality of these devices can significantly impact patient compliance, ease of use, and overall treatment efficacy.
Patent Overview
Invention Description
The patent 9,687,611 describes an injection device that incorporates a torsion spring and a rotatable display. The device is designed to set and display doses accurately, enhancing user convenience and safety. Key components include:
- A dose setting member adapted to set a dose of a medicament.
- A torsion spring operatively connected to the dose setting member.
- A rotatable display that shows the set dose[4].
Claims Analysis
Independent Claims
The patent includes several independent claims that define the scope of the invention. For example:
- Claim 1 describes the method of operating the injection device, including setting a dose using the dose setting member and displaying the dose on the rotatable display.
- Claim 10 outlines the device itself, including the torsion spring and the rotatable display mechanism[4].
Dependent Claims
Dependent claims further specify and narrow down the invention by adding additional features or limitations to the independent claims. These claims help to protect specific aspects of the invention, such as the mechanism for rotating the display or the interaction between the torsion spring and the dose setting member.
Enablement Requirement
As highlighted in the Amgen v. Sanofi case, the enablement requirement under 35 U.S.C. § 112(a) is crucial. The specification of the patent must enable a person skilled in the art to practice the full scope of the claimed invention. For patent 9,687,611, the specification must provide sufficient detail on how to make and use the injection device, including the torsion spring and rotatable display mechanisms, to ensure that the invention is fully enabled[3].
