Summary for Patent: 10,314,850

Title:	Use of ACTH in assessment and prophylactic treatment of hypokalemia associated with glucocorticoid receptor modulator treatment of Cushing's syndrome patients
Abstract:	This invention provides new methods for a) identifying Cushing's Syndrome patients at high risk of developing hypokalemia during glucocorticoid receptor modulator (GRM) treatment, and b) for prophylactically treating such patients to prevent, or reduce the severity of, hypokalemia. Patients at such high risk may be identified prior to their developing hypokalemia. Such a patient may be an adult patient with endogenous Cushing's Syndrome having type 2 diabetes mellitus or glucose intolerance to control hyperglycemia secondary to hypercortisolism. Patients may be identified by an above-threshold level of ACTH or cortisol in a patient sample taken post-GRM administration or pre-GRM administration, respectively. Upon identifying such a patient prior to the development of low potassium, the present methods provide for prophylactically treating the patient by administration of one or more hypokalemia treatments concurrently with an increased dose of GRM or with an initial dose of GRM to prevent hypokalemia.

Understanding the Scope and Claims of United States Patent 10,314,850: A Comprehensive Analysis

Introduction

When analyzing a patent, it is crucial to delve into its scope, claims, and the broader patent landscape to understand its significance, validity, and potential impact. This article will provide a detailed analysis of United States Patent 10,314,850, focusing on its claims, scope, and the relevant patent landscape.

Patent Overview

Patent Number and Title

United States Patent 10,314,850 is a utility patent that was granted on June 4, 2019. The title of the patent provides the first clue to its subject matter, which is essential for understanding its scope.

Inventors and Assignees

Identifying the inventors and assignees can offer insights into the patent's origins and potential applications. This information is available in the patent's front page and can be found through the USPTO's patent search tools[4].

Claims Analysis

Independent and Dependent Claims

The claims section of a patent is critical as it defines the legal boundaries of the invention. Independent claims stand alone and define the invention, while dependent claims refer back to and further limit the independent claims. Analyzing the number and complexity of independent and dependent claims can provide insights into the patent's scope and breadth[3].

Claim Language and Scope

The language used in the claims is precise and technical, and it must be interpreted carefully. Longer independent claims often indicate a more complex invention, while shorter claims might suggest a narrower scope. The count of independent claims can also indicate the breadth of the invention[3].

Patent Scope

Measuring Patent Scope

Patent scope can be measured using metrics such as independent claim length and independent claim count. These metrics help in understanding whether the patent claims are broad or narrow. Narrower claims are often associated with a higher probability of grant and a shorter examination process[3].

Patent Maintenance Payments and Forward Citations

The scope of a patent can also be inferred from patent maintenance payments and forward citations. Patents with higher maintenance payments and more forward citations typically have a broader scope and greater impact on the field[3].

Patent Landscape

Prior Art and Related Patents

Understanding the prior art and related patents is essential for assessing the novelty and non-obviousness of the invention. Tools like the USPTO's Patent Public Search, Global Dossier, and Common Citation Document (CCD) can help in identifying prior art and related patents[4].

International Patent Offices

To fully understand the patent landscape, it is important to search international patent databases such as those provided by the European Patent Office (EPO), Japan Patent Office (JPO), and the World Intellectual Property Organization (WIPO)[4].

Obviousness-Type Double Patenting (ODP)

ODP Analysis

In cases where multiple patents are filed for the same invention, an ODP analysis is crucial to prevent an inventor from securing a second, later-expiring patent. This analysis ensures that the patent term is not extended unfairly, as seen in cases like In re Cellect LLC[1].

Terminal Disclaimers and Patent Term Adjustments

Terminal disclaimers and patent term adjustments (PTA) can affect the patent term. A terminal disclaimer can limit the term of a patent to prevent ODP, while PTA can extend the patent term due to delays in the patent prosecution process. However, PTA does not extend the term past the date of a terminal disclaimer[1].

Litigation and Enforcement

Small Claims Patent Court

The feasibility of a small claims patent court has been discussed as a way to make patent litigation more accessible and less costly. This could impact how patents like 10,314,850 are enforced and litigated in the future[5].

Industry Impact

Innovation and Licensing

The breadth and clarity of patent claims can influence innovation and licensing costs. Broader, less clear claims can lead to increased litigation and licensing costs, which can diminish incentives for innovation[3].

Key Takeaways

• Claims Analysis: Understanding the independent and dependent claims is crucial for defining the legal boundaries of the invention.
• Patent Scope: Metrics such as claim length and count, along with maintenance payments and forward citations, help in assessing the patent's scope.
• Patent Landscape: Searching prior art and related patents, both domestically and internationally, is essential for assessing novelty and non-obviousness.
• ODP Analysis: Ensuring that the patent does not fall under ODP is vital to prevent unfair extension of the patent term.
• Litigation and Enforcement: The potential for a small claims patent court could change how patents are enforced and litigated.

FAQs

Q: How do I search for existing patents related to my invention?

A: You can use the USPTO's Patent Public Search tool, Global Dossier, and other international patent databases to search for existing patents related to your invention[4].

Q: What is the significance of independent and dependent claims in a patent?

A: Independent claims define the invention, while dependent claims further limit the independent claims, providing a clearer definition of the invention's scope[3].

Q: How does ODP analysis affect patent term?

A: ODP analysis prevents an inventor from securing a second, later-expiring patent for the same invention, ensuring the patent term is not unfairly extended[1].

Q: What metrics can be used to measure patent scope?

A: Metrics such as independent claim length, independent claim count, patent maintenance payments, and forward citations can be used to measure patent scope[3].

Q: Why is it important to search international patent databases?

A: Searching international patent databases helps in identifying prior art and related patents globally, ensuring the novelty and non-obviousness of the invention[4].
