How should chemical formulae be included in a PCT application abstract?
When including chemical formulae in a PCT application abstract, follow these guidelines:
- Include the chemical formula that best characterizes the invention.
- Choose the most characteristic formula among all formulae contained in the application.
MPEP 1826 states: “Where applicable, the chemical formula which, among all the formulae contained in the international application, best characterizes the invention.” This means you should select the formula that most clearly represents the inventive concept.
