Understanding the scope and claims of a patent is crucial for inventors, businesses, and legal professionals. This article delves into the details of United States Patent 10,875,893, focusing on its claims, scope, and the broader patent landscape.
Patent Overview
United States Patent 10,875,893 is associated with Apellis Pharmaceuticals Inc., a company known for its innovative pharmaceutical products. To analyze this patent, we need to look at its core components:
Inventors and Assignees
The patent is assigned to Apellis Pharmaceuticals Inc., with inventors such as Cedric Francois and Pascal Deschatelets, who are key figures in the development of the patented technology[4].
Patent Issue Date and Expiration
The patent was issued on December 29, 2020. The expiration date, considering standard patent terms and any potential extensions, would typically be 20 years from the filing date, unless extended under specific provisions like the Hatch-Waxman Act[4].
Claims Analysis
Claim Structure
Patent claims are the heart of any patent, defining the scope of protection. For U.S. Patent 10,875,893, the claims can be categorized into independent and dependent claims.
- Independent Claims: These claims stand alone and define the broadest scope of the invention. They are critical in determining the patent's scope and are often the subject of litigation and licensing negotiations[3].
- Dependent Claims: These claims build upon the independent claims, adding specific limitations and details. They help in narrowing down the invention and can provide additional protection against infringement[3].
Claim Language and Scope
The language used in the claims is precise and technical, reflecting the complexity of the invention. For example, claims might describe specific chemical structures, manufacturing processes, or methods of use. The scope of these claims is measured using metrics such as independent claim length and independent claim count, which can indicate the breadth and clarity of the patent[3].
Patent Scope
Metrics for Measuring Scope
Research has shown that metrics like independent claim length and independent claim count can be effective in measuring patent scope. These metrics can correlate with other indicators such as patent maintenance payments, forward citations, and the breadth of patent classes[3].
Impact on Innovation
The scope of a patent can significantly impact innovation. Broader patents may lead to increased licensing and litigation costs, potentially discouraging further innovation. Conversely, narrower claims can facilitate a smoother examination process and higher grant probabilities[3].
Patent Landscape
Related Patents
Apellis Pharmaceuticals Inc. has a portfolio of patents related to the drug Empaveli (pegcetacoplan), including U.S. Patent 10,875,893. These patents cover various aspects such as the composition of the drug, methods of use, and manufacturing processes. Understanding the interplay between these patents is essential for navigating the intellectual property landscape[5].
Patent Term Extensions
Patents can be extended under certain conditions, such as delays in FDA approval. For instance, U.S. Patent 10,125,171 B2, related to the same drug, has been subject to a patent term extension application to extend its term from August 2, 2033, to March 4, 2035[4].
Search and Analysis Tools
USPTO Resources
The United States Patent and Trademark Office (USPTO) provides several resources for searching and analyzing patents. The Public Search Facility and the Main STIC Library offer expert assistance in searching foreign patents and other patent documentation[1].
Patent Claims Research Dataset
The USPTO's Patent Claims Research Dataset is a valuable resource for analyzing patent claims. It includes detailed information on claims from US patents granted between 1976 and 2014 and US patent applications published between 2001 and 2014. This dataset can help in understanding trends and metrics related to patent scope[2].
Legal and Regulatory Aspects
FDA Approval and Regulatory Review
The patent in question is associated with a drug that has undergone FDA approval. The regulatory review period and any subsequent transactions related to FDA determinations are crucial in understanding the patent's validity and enforcement[5].
Maintenance Fees and Extensions
