Compton scattering is an example of inelastic scattering. The incident photon loses energy in the lab frame, which centuries of practice had identified with inelastic scattering—even though, in the c.m. frame, the respective masses remaining the same, no new species are created and kinetic energy is conserved, the mark of an elastic collision.
