I spoke to a patent attorney way back in the day and he thought I had a good idea and told me to imagine myself running the hurdles, in a dense fog, with the hurdles spaced indiscriminately and that there was no end to the race.
Also, if someone were to steal your idea, it would take well over a year for a favorable judgment and the thief of your idea would still be cranking out your product, making money off of it.
Needless to say, I didn't go through with it due to lack of resources on my end. Do your due diligence, as advised.
All the best,
