I have developed an electronic circuit using standard spice simulation software which can be used to charge a battery such that if the current from the battery is withdrawn at a rate less than the self charging current from the circuit, it can never run out of charge. The circuit essentially acts as a negative resistor (i.e an overunity circuit). To Support my claim, I am attaching image of the current taken in by the circuit and the current it produces at the output to charge the battery or to provide current to run other circuits at that voltage. In the image, a three volt battery is used. The blue line is the voltage that shoots up to 3.7 volts and remains constant as the circuit starts to work. Green line is the current that starts to flow back into the battery and red line is the initial current drawn to run the circuit and quickly decays to zero. In the picture, the current generated by the circuit is already more than the initial current used to kick start the circuit.

How can I patent this discovery without a fear of rejection. I can provide all the simulation results but the circuit defies the logic and that is what worries me.

The claims of almost every single patent submitted to the PTO are at least partially rejected. So, I wouldn't let that scare you off.  The nature of getting a patent is that you go in looking to patent the whole enchilada, and you wind up getting a few bites of it patented.

Retain a patent agent/lawyer with experience in your field, describe your invention, and they will be able to tell you whether it's worth the $ to try to get a patent.

Most attys/agents charge at least $225/hour, and if you ask them to commission a prior art search, you'll be looking at another $1,000 for the search, plus maybe a couple hours of atty work looking at the search results.

I appreciate your answer. I am already in contact with couple of experts who are also intrigued to see what is happening.Once I understood the principle, I created several different versions of it and generated power  from any where between a few milliwatts to up to 30 watts per circuit continuously for days of simulations.  I do not intent to patent it as an Overunity circuit. Instead may be patent the principles or patent it as an efficient power supply  recharging circuit or as a dc-dc power conversion circuit etc etc. I do not know the full answer yet but I do appreciate your input.
