Nikon sues Polaroid/Sakar for mirrorless camera design patent and trade dress infringement

Polaroid-mirrrorless-camera

Do you remember the Android based Polaroid IM1836 interchangeable lens camera that looked very much like the Nikon 1 J1/J2 models? Even the 30-110mm lens looked identical to the Nikkor 1 30-110mm f/3.8-5.6. Nikon also thinks that Sakar/Polaroid ripped their Nikon 1 camera design and filed today a lawsuit in the U.S. for design patent and trade dress infringement. Here […]

Nikon filed a patent in Japan (2013-156379) for electrically turning ON or OFF the optical low-pass (OLPF) a.k.a. anti-aliasing (AA) filter. Currently the Nikon D800E and D7100 do not have AA filters on their sensors. Nikon filed a similar patent back in 2011 which offered a mechanical ON/OFF solution. Another patent from last year suggested adding the OLPF inside the lens. Detailed description […]
