Nikon Patent 43mm F/1.8 VR Lens for APS-C Cameras

A Nikon patent has been published which appears to show the formula for a 43mm F1.8 Lens with built in Vibration Control for APS-C cameras. It is unclear from the patent wording if 43mm is the 35mm equivalent focal length of the lens, which would make it a 27mm f/1.8, or if 43mm is the lenses true focal length, giving a 35mm equivalent of 69mm when used an an APS-C sensor camera.
