Comprehensive Analysis of United States Patent 10,000,554: Modified Laminin Containing Collagen Binding Molecule
Introduction
United States Patent 10,000,554, titled "Modified laminin containing collagen binding molecule and use thereof," presents a significant innovation in the field of biomaterials and tissue engineering. This patent, issued to address specific needs in biomedical research and applications, involves the modification of laminin, a crucial protein in the extracellular matrix, to enhance its interaction with collagen.
Background on Laminin and Collagen
Laminin and collagen are key components of the extracellular matrix, playing vital roles in cell adhesion, differentiation, and tissue structure. Laminin, in particular, is involved in various biological processes, including cell migration, angiogenesis, and wound healing. The integration of laminin with collagen binding molecules aims to create a more stable and functional biomaterial for tissue engineering and regenerative medicine[1].
Patent Overview
Publication Details
- Publication Number: US10000554B2
- Prior Art Date: The patent builds on existing knowledge in the field of biomaterials and tissue engineering.
- Legal Status: Active, with an expiration date based on the patent term.
Claims and Inventions
The patent describes a modified laminin that includes a collagen binding molecule. This modification is designed to enhance the interaction between laminin and collagen, creating a more stable and functional biomaterial. The claims cover various aspects of this invention, including the modified laminin itself, methods for its production, and its use in biomedical applications.
Subject Matter Eligibility
35 U.S.C. § 101 Analysis
To determine the patentability of the modified laminin, it is essential to analyze its subject matter eligibility under 35 U.S.C. § 101. The USPTO uses a two-pronged framework, known as the Alice/Mayo test, to evaluate whether a claimed invention is directed to an abstract idea or a law of nature.
Prong One: Abstract Ideas
The first step involves determining whether the claims recite one of the enumerated groupings of abstract ideas, such as mathematical concepts or mental processes. In this case, the claims are directed to a specific biomaterial and its method of production, which are not abstract ideas[4].
Prong Two: Practical Application
The second step requires evaluating whether the claim elements beyond those corresponding to the alleged abstract idea integrate the abstract idea into a practical application. Here, the modification of laminin to include a collagen binding molecule represents a specific, concrete technological advancement. This integration improves the functioning of the biomaterial in tissue engineering applications, making it patent-eligible under Prong Two[4].
Novelty and Nonobviousness
Novelty Requirement
For a patent to be granted, the claimed invention must be novel, meaning it must not have been patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date. The modification of laminin to include a collagen binding molecule is a new and unique invention that adds to the total stock of knowledge in the field.
Nonobviousness Requirement
The claimed invention must also be nonobvious, meaning it must not be obvious to a person of ordinary skill in the art (POSA) at the time of the invention. The combination of laminin with a collagen binding molecule is not an obvious step, as it requires a deep understanding of the biochemical interactions between these proteins and their roles in tissue engineering.
Double Patenting
The patent system prohibits double patenting, where two patents issue on the same invention to the same inventor or where there is a common inventor or applicant/assignee. The claims in US10000554B2 are distinct and do not overlap with any prior patents held by the same inventive entity, thus avoiding any double patenting issues[3].
Practical Applications and Benefits
Tissue Engineering
The modified laminin with a collagen binding molecule has significant potential in tissue engineering. It can be used to create more stable and functional scaffolds for cell growth and differentiation, enhancing the outcomes of tissue regeneration and repair.
Biomedical Research
This biomaterial can also be used in various biomedical research applications, such as studying cell behavior, testing drug efficacy, and developing new therapeutic strategies.
Challenges and Controversies
Patent Policy and Competition
The patent landscape, particularly in the context of biomedical innovations, can be complex and contentious. For instance, the PTAB's approach to reviewing plant utility claims has raised concerns about competition in seed markets, highlighting the broader issues of patent policy and its impact on innovation and competition[2].
