We are releasing our list of clean tech patents, from 1975-2012. We worked with IP Checkups' Kathryn Paisner to identify biofuel, solar, wind, hydro, geo, and nuclear patents, and then combed through the rest of the database to look for similar but unidentified patents. Dr. Paisner then went through and vetted those patents. Guan Cheng Li and Ken Younge did the heavy lifting computationally.
