Propose a business plan to meet the ATACM's capabilities for far less. The Pentagon will be at your door with flowers in a matter of minutes. Trademarks, patents, and copyrights are trivial niceties, when national defense is on the line.

Edit: what you don't see, and are assuming doesn't happen, is the vicious competition that goes on before a military contract is sealed. Grift and overspending happen, because: humans, but weapons are made by the lowest bidder who meets the advertised goals of the program, every time.
