I could definitely "use an extra 50 or 100 grand". I've has an attorney send a cease&desist letter, and recieved a terse response. It's litigate, not negotiate. But litigation is a complicated decision, and what's right, or wrong, isn't the only contributing factor. The parent corporation of the offending company has annual revenues of $50 billion. Bringing a lawsuit could cost me $200,000, or more. What's the risk/benefit ratio?
As my father told me, life is hard.
The father of one of DFA's friends owns a cleaning products company called 'Clean-Up', and he went through some similar business when Clorox came out with a product called 'Clean-Up'. He got it worked out so Clorox either paid him a lump sum for use of the name, or they pay him every time they sell some, the Doctor can't recall which.
