Using a sample of 158×106 ?(2S) events collected with the Belle detector, we search for the first time for double-charmonium decays of the P-wave spin-triplet bottomonium states (?(2S)???bJ, ?bJ?J/?J/?, J/??', ?'?' for J=0, 1, and 2). No significant ?bJ signal is observed in the double-charmonium mass spectra, and we obtain the following upper limits: B(?bJ?J/?J/?)
