In the present study we consider spherical product surfaces X = α⊗β of two 2D curves in E3. We prove that if a spherical product surface patch X = α⊗β has vanishing Gaussian curvature K (i.e. a flat surface) then either α or β is a straight line. Further, we prove that if α(u) is a straight line and β(v) is a 2D curve then the spherical product is a non-minimal and flat surface. We also prove that if β(v) is a straight line passing through origin and α(u) is any 2D curve (which is not a line) then the spherical product is both minimal and flat. We also give some examples of spherical product surface patches with potential applications to visual cyberworlds. © 2009 IEEE.
