I submitted my invention to lambert and lambert. Because my invention is purely a defense or military related i am nervous to pay $199 and got rejected as they did not mention defense or military in their wanted invention list. I paid $1300 to World Patent Marketing all i got was a single report with crazy stuff in it. they didn't even let me know based on what they are doing patent search. $200 for this evaluation is necessary for evaluation for any company. But as a International Student after paying $1300 out of my college fee I still don't want to loose $200 for the same Evaluation service.
