N2 - his paper, by analysing technology attributes, examines the degree to which companies build on environmental
technologies generated by public research organisations (PROs) to develop the related technological solutions.
Three main technology attributes have been considered: (i) the level of establishment, (ii) the scope of appli-
cation, and (iii) the technological breadth. We have then developed three hypotheses about the influence exerted
by these characteristics and have chosen the green energy as the field of investigation. The analysis is based on a
sample of 4363 green energy patents registered by PROs at the United States Patent and Trademark Office in the
1976–2011 period. The results of a set of Tobit regression have revealed that the level of establishment, the
scope of application and the technological breadth of public environmental technologies are positively related to
the technological development of an industry. Hence, these findings can help advance the current debate on
whether the green outputs of public research can stimulate firms to generate environmental technologies.
