Shimon, sorry to hear this. As soon as you find a good lawyer, I wouldn't worry about it psychologically. This "patent" is total bullshit; the absence of big players such as eBay and Amazon leads me to believe that they are going after easier targets in order to establish a legal precedence so that they may go after the big guys later.
You're also in good company. I would take pride in that at the very least.
