I haven't pulled the patents, but they probably have to do with compressing the pre-debayered image. Apple sends Red a big check every year for the same patents; I believe they're part of ProRes but not sure.
Essentially, by compressing the raw RGB data coming off the sensor (where each pixel only has R, or G, or B) you avoid the data explosion of interpolating color values at each pixel. It's a technique for compressing raw files, and Red was early to the game.
Perhaps someone on here has more detailed technical info, I haven't actually read the patents, just talked to engineers close to the project.
