Work experience in engineering began at 16 as an Electrical / Instrumental Technician Apprentice with Imperial Chemical Industries (UK). Followed by a B.Sc (Hons) in Electronic Engineering at Staffordshire University and a M.Sc. in Radio and Microwave Engineering from Bradford University. After qualifying from these universities, I was employed as a Lecturer in Electrical & Electronic Engineering with St. Helens College, Merseyside (UK). Then after St. Helens College, I took up the position of Senior Lecturer with University Centre Blackburn College (Lancashire UK). 

Made Aliyah to Israel in 2006, retrained with Dr. Hanan Farber Patent Agent Ltd and worked with him for eight and half years. Here with Hanan I learned Patent drafting, prosecution and filing of applications and other associated prosecution tasks.  My tasks included discussions with inventors to identify patentable inventions. IP portfolio management included programming, design and update of docketing and billing data bases, prior art searches and reporting of and responding to ongoing prosecution findings to clients. Marketing of Dr. Hanan Farber Patent Agent Ltd by design, build and upkeep of WordPress website. 

I then worked with Solaredge Technologies in Hertzliya, at Solaredge I drafted new patent applications. To date I am listed as an inventor on four applications I drafted. Prosecuted patent applications that I wrote for SolarEdge whilst working with Dr. Alan Farber Patent Agent Ltd, when SolarEdge was in its startup phase. Patents I wrote and listed as an inventor: 1. US10554149B2 PROVIDING POSITIONAL AWARENESS INFORMATION AND INCREASING POWER QUALITY OF PARALLEL CONNECTED INVERTERS 2. US20180351401A1 CIRCUIT FOR A POWER DEVICE AND GRAPHICAL USER INTERFACE 3. US20200136523A1 Multilevel Converter Circuit and Method. I then had a brief spell as a patent specialist with Erez Patents until Corona put a temporary end to my aspirations to ‘make it’ here in Israel. 

I now work with the Ehrlich Group where my many areas of expertise and extensive experiences to draft patents are fully utilized.
