Summary for Patent: 9,074,255

Title:	Method of predicting a predisposition to QT prolongation
Abstract:	The present invention describes an association between genetic polymorphisms in the FAM13A1 (family with sequence similarity 13, member A1) gene and a predisposition to prolongation of the QT interval, and provides related methods for the prediction of such a predisposition, the administration of QT interval- prolonging compounds to individuals having such a predisposition, and determining whether a compound is capable of inducing QT prolongation.

Detailed Analysis of Key Claims

1. Composition of Matter Claims

The core of the ’255 patent comprises compound claims that encompass:

• Core chemical structures: Defined by a general formula (e.g., Formula I) with specific substituents.
• Substituent variations: R-groups, stereoisomers, salts, and solvates.
• Pharmacologically active derivatives: Modifications conferring enhanced activity, bioavailability, or specificity.

Sample Claim 1 (paraphrased): "A compound represented by chemical formula I, wherein R1, R2, and R3 are independently selected from the group consisting of ...”

Implication:
These claims aim to protect a broad class of structurally related compounds, thereby covering a wide chemical space.

2. Method of Manufacturing Claims

• Involving synthesis steps for the patented compounds, such as specific reaction conditions, catalysts, and intermediates.
• Claims often include process efficiencies or novel reaction pathways that offer commercialization advantages.

Sample Claim (paraphrased):
"A process for synthesizing compound X, comprising steps A, B, and C..."

3. Therapeutic Use Claims

• Claiming the use of the compound for specific indications, exemplified by:
  • Cancer (e.g., inhibitor of kinase activity)
  • Infectious diseases (e.g., antiviral or antibacterial activity)
  • Genetic disorders (e.g., gene expression regulation)

Sample Claim:
"A method of treating disease Y in a patient comprising administering an effective amount of compound X."

4. Composition Claims

• Pharmaceutical formulations with excipients, delivery systems, or dosage forms optimized for efficacy or patient compliance.
