6 FAQs about [Photovoltaic inverter core patent]

What patents do solar companies have?

They include Schott Solar, SunPower and PowerLight patents for PV mountings and shingles, a Stanford patent describing a bi-level contact PV cell, a DOE patent for multi-junction PV cells, and Abacus Controls and MRIGlobal (National Renewable Energy Laboratory) patents for PV power management and storage.

Do DOE-funded PV patents influence future patents?

This influence can be seen both over time, and across these leading organizations. Meanwhile, the forward tracing shows that DOE-funded PV patents have had a strong influence on subsequent generations of patents. This influence can be seen both within PV technology, and in other technologies, notably semiconductors and nanomaterials.

What percentage of PV patents are funded by Doe?

There was a ten-fold increase in PV patenting between 2000 and 2011, making it much more difficult for DOE to maintain the percentage of PV patents to which it was linked. Overall, in the period 1976-2018, 1.9% of PV patent families were funded by DOE. The ten leading patenting organizations in PV technology are listed above in Table 4.

How many generations of PV patents are there?

In other words, the analysis starts with DOE-funded PV patents and traces forward for two generations of subsequent patents. This means that we trace forward through two generations of citations starting from DOE-funded PV patents; and backward through two generations starting from the patents owned by leading PV organizations.

Which patent family has the most links to Seto-funded PV patents?

Applied Materials has the patent family with the most links to SETO-funded PV patents. This family (representative patent US #7,863,084) describes back contact solar cells.

Which patent family describes back contact solar cells?

This family (representative patent US #7,863,084) describes back contact solar cells. It is linked to 18 earlier SETO-funded patent families, including MRIGlobal patents for CIGS cells, Stanford patents describing bi-level PV cells, and Sandia patents outlining solar cell encapsulation.
