Patent 9,744,209: Scope, Claims, and Landscape Analysis
What is the Scope of Patent 9,744,209?
Patent 9,744,209 covers a novel formulation of a biological drug, specifically a monoclonal antibody designed for therapeutic use. The patent’s scope centers on the composition, manufacturing process, and method of use of this antibody. It claims a stabilized formulation suitable for long-term storage, comprised of a specific combination of excipients that enhance stability and bioavailability.
The patent encompasses:
- The antibody's amino acid sequence and variations.
- The excipient formulation, including concentrations and types.
- The manufacturing process, such as purification and formulation steps.
- Methods of treatment using the antibody formulation.
The novelty lies primarily in the stabilization technique, which allows for extended shelf life without compromising activity.
How Broad Are the Claims?
The patent’s claims can be divided into three categories:
1. Composition Claims
- Cover specific antibody sequences and their variants.
- Include the stabilized formulation with precise excipient concentrations.
2. Process Claims
- Describe methods for producing the antibody with enhanced stability.
- Include steps for formulation, purification, and storage.
3. Use Claims
- Method of treating particular diseases, such as rheumatoid arthritis and certain cancers, with the stabilized antibody.
Claim breadth is moderate; it is limited by specific sequences and formulation details but potentially broad enough to cover similar antibodies with minor modifications. The claims explicitly specify the excipient concentration ranges, giving narrow bounds but also encompassing multiple formulations.
Patent Landscape and Related Patents
Key Linked Patents and Applications
- Prior Art: Several patents disclose monoclonal antibodies for autoimmune diseases and cancer.

FAQs
1. Does Patent 9,744,209 cover all monoclonal antibodies for autoimmune diseases?
No, it specifically covers a particular antibody formulation and stabilization method. It does not encompass all monoclonals or their treatments.
2. Can competitors create a similar antibody formulation?
Potentially, if they do not use the exact excipient concentrations or manufacturing steps claimed. Design-arounds are possible with different stabilization techniques.
3. How does the patent support commercialization efforts?
It grants exclusivity for the specific formulation and therapeutic use, enabling patent holders to enforce rights against infringing formulations.
4. Are there known disputes or litigations involving this patent?
Current records show no litigations. Its validity could be challenged based on prior art references related to antibody stabilization.
5. What is the significance of the patent’s process claims?
They protect particular methods of manufacturing, which could be critical for ensuring product quality and enforcement of rights in supply chains.
