Hello everyone, I'm Roberto, I've been a privat electronic researcher since 1998. I won 2 invention awards on 1998 and 1999. I worked from 1998 to 2007 to develop my inventions, new electronic active filters, and became them patents/applications.
I discovered a simple algeblical method to project active filters without compensation, and a new claim method to have less indipendent claims without limitations, which I successfully used for 2 patents going to be granted by the USPTO (with 10 indipendent claims) and by the EPO, respectively. I've filed 10 international patent applications and obtained 3 issued patents (Italy and USA) for now.
