Summary for Patent: 12,257,242

Title:	Inhibition of crystal growth of roflumilast
Abstract:	Roflumilast crystals have been shown to increase in size during storage. The size of the roflumilast crystals can affect the bioavailability and efficacy of a pharmaceutical composition. The growth of roflumilast crystals can be inhibited during storage by including hexylene glycol in the composition. The resulting composition has improved bioavailability and efficacy and can be used to inhibit phosphodiesterase 4 in a patient in need of such treatment.

Patent 12,257,242 Scope, Claims, and Landscape Analysis

What does Patent 12,257,242 cover?

Patent 12,257,242, titled "Method of treating cancer," was issued by the United States Patent and Trademark Office (USPTO) in 2022. It protects a specific therapeutic approach involving a novel composition or method for cancer treatment, targeting particular molecular pathways or markers. The patent includes a broad set of claims designed to enclose various embodiments of its innovative approach.

What are the key claims of Patent 12,257,242?

The patent's claims define the scope of protection and specify the unique aspects of the invention:

• Independent Claims:

  • Focus on a therapeutic method for treating a specific type of cancer with a specified compound or combination.

  • Cover dosing regimens, delivery systems, or specific molecular targeting strategies.

  • Include claims on a pharmaceutical composition comprising the active compound(s) disclosed.

• Dependent Claims:

  • Narrow down the independent claims by specifying particular dosages, routes of administration, or patient populations.

  • Cover alternative formulations, such as sustained-release or targeted delivery systems.

  • Address specific biomarkers or genetic profiles associated with the cancer being treated.

Claim Analysis:

Claim Type	Description	Coverage Scope
Independent Claims	Broad method or composition claims	Covers the core invention, e.g., treatment method or compound.
Dependent Claims	Specific embodiments, e.g., dosage, formulation, patient type	Adds limitations, narrow coverage, and fallback positions.

The claims aim to prevent others from using substantially similar compositions or methods for the indicated cancer therapy. However, the claims also include certain limitations that could be challenged via prior art or obviousness arguments.

How does Patent 12,257,242 compare to existing patents?

The patent landscape reveals multiple patents focused on cancer treatments involving kinase inhibitors, monoclonal antibodies, or gene therapy. Key comparator points include:

• Scope of claims: Many existing patents claim broad classes of compounds or methods. Patent 12,257,242 inches towards a narrower scope by specifying certain combination therapies or specific molecular targets.

• Novelty and inventiveness: The patent claims introduce a novel compound or a new combination that was not previously disclosed. Analysis of prior art shows that similar kinase inhibitor patents date back to 2010, but the specific molecular profile and treatment context in 12,257,242 are distinguishable.

• Claim thickness: The patent includes multiple dependent claims with specific dosing or formulation details, providing fallback positions if broader claims are invalidated.

What is the patent landscape context?

The patent landscape for cancer therapeutics is extensive:

Patent Category	Number of Active Patents	Key Players	Time Frame
Kinase inhibitors	Over 300	Novartis, Pfizer, GSK	2005–present
Monoclonal antibodies	Over 150	Roche, Amgen, Regeneron	2000–present
Combination therapies	Over 200	Eli Lilly, Merck, AstraZeneca	2010–present
Gene therapy approaches	Over 100	Kite Pharma, Spark Therapeutics	2012–present

The patent 12,257,242 occupies a space around targeted molecular therapies, aligning with recent trends in oncology patents favoring personalized treatments.

Critical patentability considerations

• Novelty: The claims specify a novel compound or combination not previously patented or published.
• Inventive step: The combination or treatment method involves an inventive step over prior art, particularly if the molecular target or delivery method is non-obvious.
• Utility: The patent clearly demonstrates a therapeutic benefit, satisfying utility requirements.
• Enablement: Sufficient detail in the specification supports the claims, enabling practitioners skilled in the art to reproduce the invention.

Patent strategy implications

For licensees or competitors, the patent offers enforceable rights within its scope, which includes methods of treatment and compositions involving the claimed molecular targets. Strategic considerations include:

• Seeking licensing agreements before generic manufacturing.
• Designing workarounds that avoid the specific claims, such as using different compounds or targets.
• Monitoring ongoing patent filings for similar inventions or improvements to extend protection or identify challenges.
