I...The general idea of RGBW goes back a long time. In fact, Bayer's original patents included such an idea. So, the only things one can defensibly patent are specific implementations and especially the color interpolation algorithm.<br />The unexpired Kodak RGBW patents are mostly the latter. They were part of a large overpriced portfolio that no one cared to purchase over the course of a couple of years. Finally the price dropped to where I guess Omnivision thought they were helpful to defend against BSI-related and other future litigation.Eric R Fossumhttps://www.blogger.com/profile/09740612324630105312noreply@blogger.comtag:blogger.com,1999:blog-19092890.post-68905946964565206172012-01-24T15:30:26.766+02:002012-01-24T15:30:26.766+02:00The RGBW patents are in OVs portofolio, as well as...The RGBW patents are in OVs portofolio, as well as all the other CMOS patents that belonged to Kodak (including several related to stacked BSI sensors).
