Practical Patent: Digital Back for Film SLRs (by Nikon)
As the patent wars intensify and armies of lawyers counter-sue each other until the judges get irritated and kick them out, so do the waves of new patents filed. Some patents are for real, some are carpet-bombing, some are defensive, some are offensive, some are to muddy the waters, some are to justify having an army of Ph.D researchers (the Yankees roster theory).
With that as a semi-unnecessary preface, Nikon has one of the most practically interesting of recently revealed patents, a digital back that can give film SLRs digital capture capability. The patent is at the Japanese patent-hunting blog Egami and it is discussed in Englishes at dpreview and Petapixel. The patent was filed in mid-2011 but was revealed two weeks ago.
