A resonancelike structure, the $P_c(4450)$, has recently been observed in the $J/\psi p$ spectrum by the LHCb Collaboration. We discuss the feasibility of detecting this structure in $J/\psi$ photoproduction in the CLAS12 experiment at JLab. We present a first estimate of the upper limit for the branching ratio of the $P_c(4450)$ to $J/\psi p$. Our estimates, which take into account the experimental resolution effects, predict that it will be possible to observe a sizable cross section close to the $J/\psi$ production threshold and shed light on the $P_c(4450)$ resonance in the future photoproduction measurements.
