I used to do work on a contract basis for a particular individual, many years ago. We are now competitors in the same industry. I have (email) evidence from the offending party of slander to potential customers. Knowing and working with this individual for several years, I'm confident the slander is wide-spread and I'm sure he's adopted it as a sales tactic, as most of the projects we lose, they are lost to him. Recently, I have spent many months and 10's of thousands of dollars developing a new product that I am getting ready to market. It is far superior to all my competitors' products and will most likely render theirs obsolete. I want to know if there's anything I can do, short of hauling the offending party into court and suing for slander. Ultimately, I would just like the slander to cease. I don't care about reaping any monetary reward. The new product line should do it's job in putting his business down, as long as I can go in with a good name. Whether this makes a difference or not, my competitor is also a licensed attorney and knows his way around business law.
