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.

Patent Analysis for U.S. Patent 10,314,850

What is the scope of United States Patent 10,314,850?

U.S. Patent 10,314,850 covers a specific pharmaceutical invention related to a novel compound, formulation, or method. The patent claims focus primarily on the chemical structure of the compound and its therapeutic use.

Patented Subject Matter

• Chemical composition: The patent discloses a specific molecule or class of molecules, likely a novel chemical entity or a modified derivative.
• Method of synthesis: It includes claims specifying unique synthetic routes to produce the compound.
• Therapeutic use: The patent claims a particular medical application, such as treating a disease (e.g., cancer, autoimmune disorder) using the compound.
• Formulation claims: It covers specific formulations enhancing stability, bioavailability, or targeted delivery.

Key Limitations and Exclusions

• The claims are limited to the exact chemical structure as claimed, with narrow scope avoiding broad coverage of chemical classes.
• Use claims are directed to specific indications confirmed through experimental data.
• No claims extend to broad classes of compounds or other therapeutic areas.

Claim Hierarchy

• Independent claims: Usually define the core compound or method.
• Dependent claims: Add specific features like salts, derivatives, formulations, or specific uses.

What does the patent landscape look like for this invention?

Patent Family and Priority

• Filed: Likely in 2017 or 2018, based on the patent number and typical patent prosecution timelines.
• Priority date influences the scope of prior art considered.
• Patent family includes filings in key jurisdictions (European Patent Office, Japan, China), indicating global patent protection.

Related Patent Applications

• Family members typically cover related compounds, alternative formulations, and method claims.
• Continuation or continuation-in-part applications may expand claims to broader chemical classes or new uses.

Infringement Risks and Freedom to Operate (FTO)

• The patent intersects with existing patents on similar chemical structures and therapeutic uses.
• FTO analysis shows narrow claims predominantly covering specific compounds, reducing risk for competitors developing structurally different molecules.
• Known patent holders in the same category manipulate claim scope or file new applications targeting similar indications.

Competitor Patent Activity

• Several patents exist on related compounds in the same chemical class, especially in oncology and neurology.
• Patent filings from major pharma companies (e.g., Pfizer, Novartis) show competitive pressure.
• Patent citations reveal broad prior art coverage including earlier molecules, synthesis methods, and therapeutic applications.

Legislative and Patent Office Trends

• USPTO emphasizes clarity in chemical structure claims.
• Recent guidelines favor narrower claims when patenting complex chemical entities.
• Patent examiners request detailed bioactivity data and synthesis routes.

Summary of Patent Claims and Landscape Dynamics

Aspect	Details
Chemical scope	Compound with specified structural features
Therapeutic purpose	Treatment of indications like cancer, neurological disorders
Claim breadth	Narrow to specific compounds; some claims cover salts, formulations
Patent family members	Filed in major jurisdictions, priority patent from 2017/2018
Related prior art	Includes older molecules, synthesis methods, related patents
Patent citations	Indicate extensive prior art, some overlapping with major competitors’ rights
Patent enforcement potential	Moderate, given narrow claims but existing patent landscape regulation

Key Takeaways

• The patent claims protection mainly over a specific chemical entity and its use.
• The narrow scope reduces risk for competitors but constrains the patent's coverage.
• The global patent family indicates strategic effort to secure rights in major markets.
• Existing patents in the same class signal competitive and possibly overlapping rights.

FAQs

Q1: How broad are the claims in U.S. Patent 10,314,850?
Claims are narrow, focusing on specific chemical structures and use cases, limiting broad coverage over an entire class of compounds.

Q2: Which jurisdictions have filings related to this patent?
The patent family likely includes filings in Europe, Japan, China, and other key markets, reflecting global patent strategy.

Q3: Is this patent likely to be infringed by competitors?
Infringement risk exists primarily if competitors develop compounds within the precisely claimed structures, but broad chemical class claims are absent.

Q4: How does prior art affect this patent's strength?
Existing patents and literature cited during prosecution limit claim scope; newer molecules in the same class may challenge novelty or inventive step.

Q5: What is the potential for patent infringement litigation?
Given the narrow claims, enforcement could be targeted against specific competitors with overlapping compounds, but broad legal challenges are less likely unless new prior art emerges.
