Clean Energy Patent Growth Index

Presented by:
THE CLEANTECH GROUP

The CLEAN ENERGY PATENT GROWTH INDEX (CEPGI) is published quarterly by the Cleantech Group  at Heslin Rothenberg Farley & Mesiti P.C. The CEPGI provides a relative indication of the effort (e.g., Research & Development) put into, and success of, Clean Energy innovation.

The CEPGI tracks the granting of U.S. patents via the following sub-components which together make up the CEPGI:

Solar
Wind
Hybrid/electric vehicles
Fuel Cells
Hydroelectric
Tidal/wave
Geothermal
Biomass/biofuels
Other clean renewable energy

The granting of patents by the United States Patent and Trademark (PTO) is an often cited measure of the outcome of inventive activity and the resources invested in developing innovations, such as research & development funding. The successful granting of a patent requires that efforts be made by inventors to develop innovations and by patent counsel to shepherd a patent application through the PTO. A patent thus is an indicator that efforts at innovation have been successful and that an innovation had enough perceived value to justify the time and expense in procuring the patent.

The Clean Energy Patent Growth Index (CEPGI) provides an indication of the trend of innovative activity from 2002 to the present along with the Top Patent Owners and the Top Countries and U.S. states for clean energy patent owners.

The patents included in the CEPGI and its sub-components have been vetted by the  Cleantech Group at Heslin Rothenberg Farley & Mesiti P.C.   to ensure that each patent is properly included in the appropriate sub-component and that the technology disclosed therein relates to the generation of energy for consumption by a device other than itself.

The CEPGI itself is a cumulation of the sub-components and has been corrected to avoid the duplicate inclusion of any patents when a patent relates to more than one clean energy technology (i.e., a patent is included in more than one sub-component).
