The company I own had a similar experience. We had this - what we thought - hot idea for an invention, and went to a patent attorney. He charged us a lot of money to research it and advise us; in the end we decided it was not profitable and didn't pursue it.
Was the money we paid the attorney wasted? Nope. Kept us from spending even more money and losing it. Now, we DID budget that money, i.e., we incorporated it into our business plan.
Ya gotta spend money to make money.
...anyway, I'm just throwing ideas out there. I've gotten tired of all the complaining with few solutions offered.
I'm out. Gotta go to work...
