Where should an "intended use" or "field of use" statement be located in a patent claim?

The correct placement of an "intended use" or "field of use" statement is in the preamble section of the claim. The preamble serves to set the context for what the invention pertains to, including the specific domain or applications for which it is designed. This information is crucial as it helps to define the scope of the claimed invention and informs the reader initially about what is being claimed, thereby providing clarity and context.

While the summary of the invention provides an overview and the background discusses prior art and issues leading to the invention, neither of these sections is designed to define the parameters of the claim itself. The claims section strictly outlines the specifics of what is being claimed in legal terms, without the need for context like an intended use statement. Hence, locating the intended use in the preamble allows for better understanding and framing of the claims that follow.
