Re: Wireless gauges
It is more the lack of funds for me. Patents and licenses can get expensive due to attorney wages more than anything. I went through that process myself with a "as seen on tv" type deal which is now being sold worldwide. Hired a company out if Florida and got taken. Lost my idea and hard earned money. Live and learn. Such matters are better done in person. Back in 2004, I thought it could be a good idea to put a cell phone clip on a beer coozie. Ended up investing almost $10K into it! At the same time, I went thru a 2 year long divorce which further drained my bank account. That company I hired told me they never promised a patent and I never got a copy of the contract as I was busy with the drama at home. I had to become my own PI in order to keep my stuff from the ex. Sobbing story aside though, my idea was mass produced and is now being sold at the price I had set initially with my submission. Just do a search for belt clip coozie and it poos up. Someone has claimed it as their idea now. I get $0 for my contribution.
Oh and another thing, beware of the online patent searches. I don't need to tell y'all potential innovators of the future but there is always someone watching what you are doing on the WWW. We are plaged with intrusive programs that let the big boys know what we like to see/buy/etc. I know because I lost another decent idea this way. Didn't even get to submit it to anyone and it was registered to someone else in another state less than a month after I did my preliminary searches!
Good luck to you as well should you decide to return to the piranha infested waters that is the legal system.
