Exciting new work on Bi2Sr2CaCu2O8+{$\delta$} (Bi2212) shows the presence of nontrivial spin-orbit coupling effects as seen in spin-resolved angle-resolved photoemission spectroscopy data [K. Gotlieb , Science 362, 1271 (2018)SCIEAS0036-807510.1126/science.aao0980]. Motivated by these observations we consider how the picture of spin-orbit coupling through local inversion symmetry breaking might be observed in cuprate superconductors. Furthermore, we examine two spin-orbit driven effects, the spin-Hall effect and the Edelstein effect, focusing on the details of their realizations within both the normal and superconducting states.
