Nikon has accused Sakar, the makers of Polaroid cameras, of patent infringement.
Nikon has launched legal action to stop the firm selling the Polaroid iM1836, an interchangeable lens camera that Nikon says looks similar to the Nikon 1 J1
The Polaroid camera uses an Android operating system, and features a touchscreen as well as interchangeable lenses that integrate a shutter and sensor.
Nikon filed the lawsuit on 11 October in the US, and Nikon's Japanese headquarters have released a statement saying that Nikon negotiated with Sakar to resolve the issue, but an agreement could not be reached. It stated Nikon initiated the lawsuit 'by necessity'.
The Polaroid iM1836 was first announced at CES in January 2013, where it was likened to Nikon's J1 and J2 cameras.
