A theory of scattering of massive chiral fermions in bilayer graphene by radial symmetric potential was developed. It was shown that in the case when the electron wavelength was much larger than the radius of the potential the scattering cross section was proportional to the electron wavelength. This led to the mobility independent on the electron concentration. In contrast with the case of single-layer, neutral and charged defects are, in general, equally relevant for the resistivity of the bilayer graphene.
