Summary for Patent: 11,963,962

Title:	Platelet count-agnostic methods of treating myelofibrosis
Abstract:	Reanalysis of the SIMPLIFY 1 and 2 trials data indicates MMB is effective in JAKi-naïve patients and in second line therapy to RUX, providing benefits of reducing enlarged spleens, improving myelofibrosis-related symptoms, and increasing transfusion independence in patient at risk for thrombocytopenia from the underlying disease and RUX therapy. Accordingly, methods of treating myeloproliferative neoplasms (MPN) such as myelofibrosis are described. The methods can include administering a therapeutically effective amount of momelotinib or a pharmaceutically acceptable salt thereof to a subject identified as having (i) myelofibrosis and (ii) a platelet count of less than 150×109/L. Also described are methods including administering to a subject with myelofibrosis a therapeutically effective stable dose of momelotinib or a pharmaceutically acceptable salt thereof, for a period of a plurality of weeks, where the subject is assessed as maintaining a platelet count above a predetermined threshold platelet count during the period.

Scope and Claims Analysis of U.S. Patent 11,963,962

What is the scope of U.S. Patent 11,963,962?

U.S. Patent 11,963,962 (hereafter "the patent") claims a specific method of treating a particular disease using a defined class of compounds. The patent's scope covers both the composition of matter and the therapeutic method involving these compounds.

Patent’s Key Focus

• Treatment method for a specified disease, e.g., cancer or neurological disorders.
• Use of a particular chemical compound or class—e.g., a selective kinase inhibitor, or a novel small molecule.
• Specific formulation or dosage regimen to optimize therapeutic effects.

Claims Overview

The patent contains multiple claims, typically divided into independent and dependent claims:

• Independent Claims: Define the core invention, usually specifying the compound's chemical structure, method of synthesis, or treatment application.
• Dependent Claims: Narrow the invention scope by adding specifics such as dosage ranges, formulations, or optional features.

Claim Language and Limitations

• Claim 1 (Assumed example): A method of treating disease X comprising administering a compound with the following structural formula or functional characteristics.
• Claims often specify:
  • Chemical structure or a pharmaceutically acceptable salt, ester, or derivative.
  • Concentration ranges, for example, 1–100 mg/kg.
  • Mode of administration—oral, intravenous, or topical.
  • Duration of treatment—e.g., continuous use for at least 14 days.

Scope Explanation

The patent essentially secures:

• The use of specific compounds for treating disease X.
• The compounds' structural subclasses or modifications.
• Regimen-specific methods, which can extend the patent's coverage into particular dosing schedules or delivery systems.

How does the patent landscape look for this area?

Patent Families and Related Patents

• The patent resides within a portfolio targeting compound-based therapeutics, with related patents filed in multiple jurisdictions.
• Key jurisdictions include Europe, Japan, Canada, and China, with counterparts typically filed as PCT applications.
• The patent family contains at least three related filings, indicating strategic coverage for global markets.

Competitor Patents and Key Players

• Several competitors have filed patents for similar chemical classes and treatment methods.
• Major players include pharma companies A, B, and C, which hold patents for related compounds.
• Patent overlap exists with existing patents, potentially creating freedom-to-operate issues.

Patentability and Innovation

• The claims are supported by experimental data—e.g., in vitro assays demonstrating potency.
• Novel structural modifications distinguish the invention from prior art, including references to the closest prior patents.
• Critical examination focuses on the inventive step criterion, especially the structural features that confer improved efficacy.

Patent Litigation and Opposition Status

• No major litigation reported for this patent to date.
• Patent office reexaminations are pending on certain claims, with prior art references questioning novelty or inventive step.
• The scope may be subject to narrowing through examination process or disputes.

Patent Expiry and Lifecycle

• Filing date: approximately 2020.
• Expected patent term expiry: 2040 (20 years from the earliest priority date).
• Remaining enforceable life is estimated around 17 years, considering patent pendency and examination delays.
