Scope of the Patent
Protected Drugs
The patent protects three major drugs:
- Ozempic (semaglutide): Used for the treatment of type 2 diabetes and for long-term weight management.
- Saxenda (liraglutide): Used for weight management.
- Victoza (liraglutide): Used for the treatment of type 2 diabetes[4].
Claim Types
The patent includes various claim types:

- Use Claims: These specify the therapeutic uses of the drugs.
- Device Claims: These relate to the injection devices used for administering the drugs[4].
Patent Claims
Claim Structure
The patent contains multiple claims, each detailing a specific aspect of the invention. Here are some key points about the claims:
- Independent Claims: These are the core claims that define the invention. Independent claims in this patent are crucial as they set the boundaries of what is protected.
- Dependent Claims: These claims build upon the independent claims, providing additional details or limitations. They are often narrower in scope than the independent claims[5].
Specific Claims
For example, claims 25, 28, and 31 of the '833 patent have been subject to litigation, particularly in the case of Novo Nordisk Inc. v. Teva Pharmaceuticals USA, Inc. These claims involve specific formulations and uses of the drugs[2].
Patent Landscape
Patent Family
The patent 8,114,833 is part of a large patent family with thirty-five family members in nineteen countries. This extensive family indicates a broad geographical protection and a comprehensive strategy to safeguard the intellectual property[4].
Litigation and PTAB Cases
This patent has been involved in several patent infringement lawsuits and PTAB (Patent Trial and Appeal Board) cases. For instance, the litigation against Teva Pharmaceuticals USA, Inc. highlights the ongoing legal battles to protect the patent's validity and scope[2][4].
Centralization in Litigation
In the context of Ozempic patent litigation, the Judicial Panel on Multidistrict Litigation (JPML) has centralized actions involving this patent in the District of Delaware. This centralization aims to eliminate duplicative discovery, prevent inconsistent pretrial rulings, and promote efficient litigation[1].
Patent Expiration and Extensions
Expiration Date
The patent's expiration date is crucial for understanding when generic versions of the protected drugs can enter the market. The original expiration date, along with any extensions, determines the period of exclusivity.
- Pediatric Extension: The protection for Saxenda has been extended by six months due to pediatric studies, as indicated by the *PED designation[4].
Supplementary Protection Certificates (SPCs)
In various countries, Supplementary Protection Certificates (SPCs) can extend the patent protection beyond the original expiration date. For example, in Australia, Brazil, Canada, and China, SPCs may provide additional protection periods[4].
Analyzing Patent Scope
Metrics for Measuring Scope
Research suggests that patent scope can be measured using metrics such as independent claim length and independent claim count. Narrower claims, as seen in the examination process, are associated with a higher probability of grant and a shorter examination process[5].
Claim Coverage Matrix
Using tools like a Claim Coverage Matrix, companies can categorize patents by claims and scope concepts. This helps in identifying which patents and claims are actively protecting the intellectual property and where gaps or opportunities exist[3].
Impact on Innovation and Litigation
Patent Quality and Innovation
The scope and breadth of patent claims can impact innovation. Overly broad patents can increase licensing and litigation costs, potentially diminishing incentives for innovation. However, well-defined and narrower claims, as seen in the '833 patent, can provide clear boundaries and encourage further innovation[5].
Litigation Costs
The involvement of this patent in multiple litigation cases highlights the significant costs associated with patent disputes. Centralizing these cases, as in the District of Delaware, can help in managing these costs and ensuring efficient litigation[1].
Key Takeaways
- Patent Protection: The patent 8,114,833 protects Ozempic, Saxenda, and Victoza, covering formulation, compound, use, and device claims.
