Transitional Phrase

A transitional phrase, in United States patent law, is a phrase that links the preamble of a patent claim to the specific elements set forth in the claim which define what the invention itself actually is. The transitional phrase acts as a limitation on the claim, indicating whether a similar device, method, or composition infringes the patent if it contains more or fewer elements than the claim in the patent.

There are three kinds of transitional phrases: open, closed, and hybrid.
