Spontaneous pattern formation and the connected superfluid current patterns of microcavity polaritons due to nonresonant pumping are studied by using nonequilibrium Gross-Pitaevskii equation in the form recently derived [H. Haug et al., Phys. Rev. B 89, 155302 (2014)]. Under a Laguerre-Gauss laser beam which is used as a resonant pumping, these patterns are shown to rotate or oscillate depending on power of resonant pumping.
