Comment Get a Lawyer (Score 1) 300
If your consulting company has any value and/or you have any interesting/promising intellectual property - then get a lawyer and discuss these issues now. Since every client slides an NDA across the table for you to sign - you need to have an NDA process that you always follow and never deviate from it. Your lawyer will help you with this. Trust me when I say that it is better to pay one lawyer a few dollars now than a team of lawyers hundreds of thousands (no kidding) of dollars when someone decides to litigate against you. You want to have that game ended before it starts with a quick summary judgement and dismissal.
P.S. The boilerplate lawsuits come from the same drawer as the boilerplate NDA's. You don't have to do anything wrong to get sued. If it serves their interests, they will sue you. It is just a business tool for them to use for control and leverage over you or other strategic factors. They are not innocent when they drop an all-encompassing, vaguely stated legal document in front of you. They paid their attorney to make it that way.
