How much does it cost to get a patent?
Between filing and legal fees, it usually costs between $70,000-100,000+ and is currently running 3-5 years for full approval (the current Administration has not made US innovation a high priority so there is a massive backlog of applications). The legal fees are the biggest part because they have people that do exhaustive searches for conflicting patents and "prior art' that could derail the application. Also, for a patent, you must be able to demonstrate/let them test the item/technique you're seeking to patent, with the exception of explosives. Really.
