What have you invented or created...only to find out that some other SOB got the patent & marketed it first?

Back in the day, Pampers did not have the handy dandy sticky tabs...you had to use diaper pins on 'em. Well, after I stuck the babies a few times (geez! I was only 10yrs old! ), she pulled out the old masking tape & voila'! No more "accidents"!!!

So, what was the Mother of your invention?

i invented egg cups
anyone sais i didnt, they are lying

I have two patents to my name (True and serious)
I am currently working on an ATR (Automatic Tampon Remover)[Joke]

"Shamwow", it was supposed to the "Shamwham"

I invented the "Party Potty". It's sort of a strap-on for girls so they can pee standing up like the guys while partying outdoors without the proper facilities.

i have a few patents. one is about to expire (i patented it when i was 12) so i'm going to try reapply. i sold a few patents to a tool company during college. they filled a really specific niche though so i didn't make a fortune or anything. high profit per unit but low volume of sales.

My daughter never would take any medicine when she was little...no matter what I tried, or mixed it with. So I started cutting freezie pops in half and adding the medicine and refreezing them. Alas ,along came pedialite freziepops... I should have gotten that out there!! (even though my daughter soon realized they tasted differant and refused them too!) It was my idea, I just did'nt know it at the time!!!!

The coat hanger...no, not really.

The keychain hanger with a button to press to make the keychain beep so you can find those d*mn things. Next is one for the remote control. Don't go stealing my idea now.

that kind of think happens to me all the time. I remember getting this great idea once to hollow out potato skins, mash the potatoes, and put the mashed potatoes back in the skin to serve. Only to find out later that this was called a "twice baked" potato and had been around forever. Several other things like this but can't recall them at the moment.

I came up with an idea that would allow you to pay your traffic ticket right after the cop wrote it. The cop would have a card reader hooked into his computer in his car. I told my computer wiz friend and he said it would cost too much and the cops wouldn't buy it.

Six months later I read about the cops in some big city using my idea. I was very annoid.

When I was about 6 or so my dad and I made a gizmo that would hold soda cans that mounted on the ash tray of his car. A few years later you could buy then in any 7 11.
