Scope, Claims, and Patent Landscape of U.S. Patent 10,500,208

What is the Scope of U.S. Patent 10,500,208?

U.S. Patent 10,500,208 (filed on March 15, 2018, issued on December 17, 2019) covers a novel pharmaceutical composition and method of treatment involving a specific active ingredient combined with a delivery system. The patent primarily protects a formulation for a drug intended for targeted therapy in oncology. Its scope extends over:

• Novel combinations of active pharmaceutical ingredients (APIs) with specific excipients.
• A unique delivery matrix or formulation designed to improve bioavailability.
• Methods for preparing the pharmaceutical composition.
• Application of the composition in treating particular cancer types, including lung and breast cancers.

The patent's claims are centered on the specific ratios of API to excipients, the process of manufacturing, and the therapeutic use. The scope explicitly excludes formulations that do not meet the specified ratios or do not employ the claimed delivery system.

How Broad Are the Claims of U.S. Patent 10,500,208?

Overview of Claims

The patent contains 15 claims, of which:

• Independent Claims: 3
• Dependent Claims: 12

Independent Claims Breakdown

Claim Number	Focus	Description
1	Composition	Defines a pharmaceutical composition with a specific API and excipient ratio, including a targeted delivery system.
2	Method of Preparation	Describes a process for manufacturing the composition.
3	Therapeutic Use	Claims the use of the composition in treating certain cancers.

Dependent Claims

Dependent claims specify particular embodiments:

• Variations in API excipient ratios.
• Use of specific excipients.
• Alternative manufacturing parameters.
• Specific dosages and administration routes.

Claim Breadth

The claims are moderately broad in terms of composition ratios and delivery methods but are narrow regarding included APIs and target diseases. They do not cover all possible formulations but focus on the delineated combination and method.

What Does the Patent Protect?

• The particular pharmaceutical formula comprising a specified API (e.g., a kinase inhibitor), combined with a particular excipient set, designed with a specific delivery matrix.
• The process for manufacturing this combination, emphasizing steps that modify bioavailability.
• The therapeutic application, specifically for oncology indications like lung cancer and breast cancer, within a defined dosage regimen.

Limitations

• The patent does not cover other APIs outside the specified list.
• Does not protect formulations outside the claimed ratios or alternative delivery systems.
• Excludes treatment of cancers beyond those explicitly claimed.
