Fujifilm files patent for color filter array with different-sized pixels

I am not sure either. When looking at some patents it seems like patent offices lets almost anything through.

In principle you are right though. Different layouts with red, green, blue, white, cyan, magenta, yellow, emerald, etc anyone can draw and claim advantages with.

I could do a dozen such patterns now on the spot.

What is more interesting with the Fuji pattern is how they plan to use micro lenses. It is not obvious.
