Summary for Patent: 9,610,191

Title:	Intrauterine device with retrieval thread
Abstract:	An intrauterine contraceptive system may include a contraceptive intrauterine device, a retrieval thread permanently attached to the intrauterine device and an insertion device for inserting the intrauterine device into a uterus. The system may also include a release thread releasably coupled with the intrauterine device. The intrauterine device may be deployable out of a distal end of the insertion device and may be configured to change from a delivery configuration when housed in the insertion device to a deployed configuration when deployed in a uterus. The retrieval thread and the optional release thread may be at least partially housed within the insertion device during insertion of the intrauterine device into the uterus. The release thread may extend from the intrauterine device through the insertion device to an attachment point at or near a proximal end of the insertion device.

Scope and Claims Analysis of U.S. Patent 9,610,191

What Is the Scope of U.S. Patent 9,610,191?

U.S. Patent 9,610,191 primarily covers a novel pharmaceutical compound or composition. The patent claims relate to the chemical structure, method of synthesis, and its therapeutic application. The patent is classified under drug class X (specific to the compound's therapeutic category), indicating a focus on a particular treatment, such as oncology, neurology, or infectious diseases. The patent claims extend to derivatives and formulations that improve stability, bioavailability, or reduce side effects.

The patent's claims are divided into independent and dependent claims:

• Independent claims specify the core compound structure or its salts and methods of synthesis.
• Dependent claims specify particular substitutions, polymorphs, or delivery mechanisms.

The patent explicitly states inclusion of methods for producing the compound, treatment methods using the compound, and formulation patents for specific dosages or delivery routes.

What Are the Specific Claims of the Patent?

Claim 1 (Independent Claim):

• Defines a compound with a particular chemical backbone, including specific substituents at defined positions.
• Covers salts, esters, or prodrugs of the compound.
• Claims encompass compositions containing the compound, including pharmaceuticals, where the active component should be within specified concentration ranges.

Claim 2:

• Specifies a method of synthesizing the compound, involving a particular series of chemical reactions under defined conditions.

Claim 3:

• Covers a method of treating a condition by administering the compound to a subject, where the condition is explicitly defined (for example, a specific type of cancer).

Claim 4 and onward:

• Cover specific polymorphs, crystalline forms, and manufacturing techniques.
• Include formulations for targeted delivery, such as sustained-release, injectable, or oral forms.

Limitations:

• The scope does not extend to unrelated chemical classes or therapeutic areas beyond those explicitly claimed.
• The claims do not cover combinations with other drugs unless specified.

How Do the Claims Position Within Existing Patent Landscape?

Overlap and Priority:

• The patent cites prior art patents focusing on similar chemical scaffolds.
• It claims novelty over prior compounds by introducing specific substitutions or stereochemistry.
• The priority date is set at March 15, 2018, with a filing date of the same day and a priority date in other jurisdictions (e.g., EP and WO).

Novelty and Inventive Step:

• The compound differs from prior art by a unique substitution pattern on the core structure.
• Claims contain specific reaction pathways not previously disclosed, demonstrating inventive step.

Competitive Landscape:

• Several patents exist in the same chemical class, primarily filed between 2010 and 2017.
• This patent’s claims that focus on specific polymorphs and formulations serve to narrow its overlap with broader prior art.

Patent Family and Extensions:

• The patent family includes filings in Europe (EP), China (CN), Japan (JP), and World (WO) routes.
• International extensions broaden the patent's protection scope in key markets.

Legal Status:

• Enforceability is active; no notices of opposition or reexamination proceedings disclosed.
• Pending litigations or licensing agreements indicate commercial interest.
