The first patent application is rather unusual – it describes a Nikon 100mm f/2.5 medium format lens. As far as I can remember, this is the first medium format lens patent from Nikon.
Nikon filed a patent for a mirrorless 10mm f/2.0 lens (28mm equivalent) with 9 elements in 2 groups and 2 aspherical elements.
There are also two other patents for a new AE sensor RGBW (or RGBY) array where the W (Y) will measure the brightness of a scene and a “transparent organic EL” that I assume is a layer on top of the sensor and can be used as a shutter or a ND filter.
