Frontier IP (FIPP)    portfolio company, Pulsiv Solar Limited, has further strengthened its intellectual property with the granting of a patent in Japan. This is the Company’s 13th patent covering power conversion and solar microinverter technologies. Further patents have been granted in the United States, Europe, China, Taiwan, Australia and Mexico. A further patent is proceeding to grant in China. 

Pulsiv Solar has also successfully integrated its technology into a standard battery charger commonly used by power tools. The technology significantly improves energy efficiency and has already attracted strong interest from potential industry partners. In addition, Pulsiv has improved the power factor of the charger to over 90% and reduced heat generation. 

The portfolio company is working with Robert Bosch Limited, a subsidiary of Robert Bosch GmbH, to optimise the design of the Company's energy-efficient solar micro inverter prototype. Once the prototype moves into full-scale production Pulsiv will be able to market the micro-inverters as "Engineered by Bosch".  

Pulsiv has also received a £129,929 grant from Innovate UK, the UK's Innovation agency. 

Frontier IP holds an 18.9 per cent equity interest in Pulsiv. 

Shares in Frontier IP opened flat in early morning trading. 

Pulsiv Solar technical director Dr Zaki Ahmed said: "We're delighted to be granted a patent in Japan. We are making strong progress and are very excited about the potential for our technology in the type of battery charger used by millions of devices every day."  

Frontier IP chief executive officer Neil Crabb said: "Pulsiv continues to go from strength to strength. Its success in integrating its technology into a standard battery charger used by devices such as power tools worldwide is a further demonstration of the Company's enormous potential."
