Understanding the Scope and Claims of United States Patent 8,642,600
Introduction to Patent 8,642,600
United States Patent 8,642,600, titled "Method of treating autism," is a patent that outlines a specific method for treating disorders of the central nervous system, particularly those associated with certain receptor subtypes. Here, we will delve into the key components of this patent, including its scope, claims, and the broader patent landscape.
Patent Structure and Components
Document Number and Type
The patent number, US8642600B2, indicates that this is a U.S. patent with a previously published application, as denoted by the "B2" code[1].
Title and Abstract
The title of the invention is "Method of treating autism," and the abstract provides a brief, non-technical description of the method. This abstract is crucial for understanding the general purpose and scope of the patent[1].
Field of Search and Classifications
The patent includes classifications such as IPC (International Patent Classification) and national classifications. For example, the national classification might include codes that specify the technical field, such as those related to medical treatments or neurological disorders[1].
Inventors, Applicants, and Assignees
The patent lists the inventors, the applicant (the person or organization that filed the application), and the assignee (the owner of the patent at the time it was issued). These details are essential for understanding the ownership and development history of the patent[1].
Claims: The Heart of the Patent
Definition and Purpose
The claims section is the most critical part of the patent, as it defines the scope of protection. Claims are paragraphs located at the end of the specification that begin with phrases like “I claim” or “What is claimed.” These claims outline the legal boundaries of the invention, similar to how a property deed defines physical boundaries[1].
Claim Construction
Claim 1 of the '600 patent, like other claims, would be constructed to clearly define what is being patented. This involves a detailed description of the method, including any specific steps, materials, or conditions necessary for the treatment. Claim construction is a critical process in patent litigation, as it determines the scope of the patent's protection[5].
Number and Complexity of Claims
While a patent must have at least one claim, most patents, including the '600 patent, typically have multiple claims. These claims can range from independent claims that stand alone to dependent claims that refer back to other claims. The complexity and number of claims can vary significantly, with some patents having hundreds of claims[1].
Specification and Drawings
Detailed Description
The specification is a written description of the invention that includes a discussion of related prior art, a description of the drawings, how the invention solves a specific technical problem, and the preferred embodiment of the invention. This section must provide enough detail so that anyone with ordinary skill in the same technical field can understand and replicate the invention[1].
Drawings
The drawings section contains black and white drawings that illustrate the technical details of the invention. While drawings are not required for all types of inventions (e.g., process or method patents), they are often crucial for understanding complex technical aspects of the invention[1].
Prior Art and Field of Search
Prior Art References
The patent includes references to U.S. and foreign patent documents and other publications cited as related prior art by the inventor and the patent examiner. This section helps in understanding the existing knowledge in the field and how the current invention differs from or builds upon previous work[1].
Field of Search
The field of search section lists the classifications consulted by the patent examiner during the prior art search. This information is valuable for understanding the breadth of the search and the relevance of the prior art cited[1].
Patent Landscape and Litigation
Related Patents
The '600 patent is part of a larger portfolio of patents related to the treatment of central nervous system disorders. Other patents, such as U.S. Patent Nos. 5,006,528, 7,053,092, 8,017,615, 8,580,796, 8,642,760, and 8,759,350, are often cited together in litigation and regulatory filings. These patents collectively protect various aspects of the treatment methods and compounds involved[5].
Litigation Examples
Cases like Otsuka Pharm. Co. v. Zydus Pharms. U.S. & Cadila Healthcare Ltd. and Otsuka Pharm. Co. v. Torrent Pharms. Ltd. illustrate how these patents are used in litigation. These cases often involve claims of direct and induced infringement, where the patent holder seeks to protect their intellectual property rights against generic or competing products[2][5].
Economic and Research Implications
Patent Claims Research Dataset
The USPTO's Patent Claims Research Dataset provides detailed information on claims from U.S. patents, including those related to medical treatments. This dataset can be used to analyze trends in patent scope and the complexity of claims over time, offering insights into the evolving landscape of medical patenting[3].
Patent Scope Measurements
Research papers like "Patent Claims and Patent Scope" by Marco, Sarnoff, and deGrazia discuss the measurements of patent scope and how they are derived from parsed claims text. These studies help in understanding the breadth and depth of patent protection in various fields, including medical treatments[3].
