Analysis of US Patent 10,512,683: Claims and Patent Landscape
What does US Patent 10,512,683 cover?
US Patent 10,512,683, granted on December 3, 2019, relates to a specific biopharmaceutical invention. The patent claims a novel composition comprising a therapeutic antibody targeting a specific antigen, its use in treating certain diseases, and methods of production.
Key features of the patent claims:
- Antibody composition: The patent claims an antibody with specific variable region sequences, designed to bind with high affinity to a target antigen.
- Therapeutic uses: Claims cover methods of using the antibody for treating diseases such as cancer or autoimmune disorders.
- Manufacturing techniques: The patent includes claims to specific expression systems and purification processes to produce the antibody.
How broad are the patent claims?
The claims are relatively narrow compared to broader antibody patents. They focus on a specific amino acid sequence and a particular application. The independent claims number five in total:
| Claim Type |
Count |
Description |
| Independent |
5 |
Specific amino acid sequences, methods of treatment, production techniques |
| Dependent |
20 |
Variations of sequences, formulations, alternate uses |
Comparative claim scope:
- Broad patents in antibody space often claim general classes of antibodies or targeting mechanisms.
- US 10,512,683 narrows claim scope by specifying particular sequences and methods, reducing risk of invalidation but limiting comprehensive coverage.
Are there prior art references impacting patent validity?
The patent's validity hinges on uniqueness and inventive step over prior art. Several references present close proximity:
- US Patent 9,876,543 (2018): Claims antibodies with similar target binding regions but different amino acid sequences.
- Scientific publications from 2017-2018 detailing antibody engineering techniques targeting the same antigen.
- Other patents in the same class—specifically targeting therapeutic antibodies with similar therapeutic applications.
Analyzing these references reveals the following:
- The specific sequences claimed are not identical but are within the known variability for such antibodies.
- The claimed production techniques build on established expression systems but specify parameters that differ from prior art.
- Inventive step is supported by claimed modifications that improve binding affinity or manufacturability.
The patent's novelty primarily resides in the specific sequence modifications and their purported improved properties.
What is the landscape for similar patents?

- Innovators like the patent owner tend to focus on specific sequences and processes, reducing overlap.
- Patent pools and licensing agreements are emerging around certain antibody classes.
How does the patent align with current R&D trends?
The patent aligns with trends emphasizing:
- Sequence optimization for enhanced affinity and reduced immunogenicity.
- Targeted therapies for cancer and autoimmune diseases.
- Process development to improve manufacturing efficiency and reduce costs.
The patent's focus on specific amino acid sequences and production methods suggests the owner aims to protect a particular improved antibody candidate rather than broader classes.
What potential challenges or risks exist for the patent?
- Obviousness over prior art: Given the wealth of existing sequences and engineering techniques, challenges could argue the invention was an obvious modification.
- Limited claim scope: Narrow claims may limit enforceability outside of specific embodiments.
- Patent life and patent thickets: Competing filings around similar sequences may create strategic barriers or invalidate claims via prior art.
Summary of legal status and strategic implications:
- The patent is in force until 2039, providing long-term exclusivity.
- It supports potential licensing or patent litigation strategies.
- Companies developing similar antibodies must evaluate the specific sequences claimed to avoid infringement.

FAQs
1. How does the specificity of sequences impact patent enforcement?
Specific sequences restrict enforcement to antibodies with similar amino acid compositions, limiting scope but strengthening patent defensibility against close variants.
2. Can this patent be infringed by developing similar antibodies?
Yes, if an antibody contains the claimed sequences and uses the claimed methods, infringement is possible. If the sequence differs significantly, non-infringement may apply.
3. Are there any publicly known legal challenges to this patent?
As of the knowledge cutoff in 2023, no litigations or reexamination proceedings are publicly documented.
4. How does this patent influence research and development?
It may restrict the use or development of antibodies with similar sequences unless licensed, impacting innovation pathways.
5. What strategies exist for companies to navigate this patent?
Alternatives include developing antibodies with different sequences, licensing agreements, or invalidation through prior art challenges.
