Introduction
United States Patent 9,616,180, titled "Automatic Injection Device with a Top Release Mechanism," is a significant patent in the pharmaceutical and medical device sector. This patent is owned by Novo Nordisk A/S and protects key aspects of their drugs OZEMPIC (semaglutide) and SAXENDA (liraglutide). Here, we will delve into the scope, claims, and the broader patent landscape surrounding this patent.
Patent Overview
Issuance and Ownership
The patent was issued on April 11, 2017, by the United States Patent and Trademark Office (USPTO) to Novo Nordisk A/S. It is part of a larger portfolio of patents that Novo Nordisk holds to protect its innovative medical devices and pharmaceutical products[2].
Scope of the Patent
Protected Products
This patent specifically protects the automatic injection devices used for administering OZEMPIC and SAXENDA. These devices are crucial for the safe and efficient delivery of these medications, which are used to treat conditions such as type 2 diabetes and obesity[1].
Top Release Mechanism
The patent focuses on the "top release mechanism" of the injection device. This mechanism is designed to ensure that the device operates smoothly and reliably, providing feedback to the user when the injection is complete. This innovation enhances user experience and ensures accurate dosing[2].
Claims of the Patent
Detailed Description
The patent includes multiple claims that describe the various aspects of the automatic injection device. These claims cover the structural components, the operational mechanism, and the user feedback system. Here are some key claims:
- Claims related to the device structure: These include descriptions of the housing, the dose setting mechanism, and the injection needle.
- Claims related to the top release mechanism: These detail how the mechanism operates to release the dose and provide feedback to the user.
- Claims related to user feedback: These cover the visual, auditory, or tactile feedback provided to the user to indicate the end of the dose[2].

Expiration and Extensions
Estimated Expiration
The patent is set to expire, but the exact date can vary based on supplementary protection certificates (SPCs) and any extensions granted. For example, protection for SAXENDA has been extended six months due to pediatric studies[1].
Impact on Innovation and Competition
Patent Quality and Scope
The scope and claims of this patent reflect the broader debates on patent quality. Narrower claims, such as those in this patent, are often associated with a higher probability of grant and a shorter examination process. This suggests that the USPTO has been effective in evaluating and narrowing the scope of patent claims during the examination process[3].
Competitive Landscape
The robust patent protection provided by 9,616,180 and related patents helps Novo Nordisk maintain a competitive edge in the market. This protection prevents generic competitors from entering the market until the patents expire, ensuring that Novo Nordisk can continue to innovate and invest in research and development without immediate generic competition[4].
