Solar PV Inverter Patent Portfolio


24 Total Patents Across 4 Families, with 8 Representative Claim Charts

Tangible IP is pleased to represent Dr. Rajiv Varma’s pioneering work highlighting technologies relevant to Solar Photovoltaic (PV) Inverters. The portfolio consists of 4 patent families including 24 patents assets in total (20 granted- 4 pending), 10 issued US patents along with 10 granted foreign counterparts in Europe (Germany, UK & France), China, India, and Canada. The portfolio’s earliest priority date is September 2009 and some of the patents will remain in force until 2034. The main patents on offer generally relate to using an inverter-based power generation source as a STATic synchronous COMpensator (STATCOM), by utilizing its reactive power capacity and method of use. The technical solution described in the portfolio has been widely adopted by leading solar PV inverter manufacturers and directly by solar PV power plants. More recently, some of the patented inventions have been described in the IEEE Standard 2800-2022 for Interconnection and Interoperability of Inverter-Based Resources (IBRs) Interconnecting with Associated Transmission Electric Power Systems. There are 8 total claim charts prepared against 6 industry leaders in the solar PV Inverters industry as well as 2 charts that read directly on the 2800 Standard.
