Okay, I came up with a few inventions a few years ago. I had drawn some plans (per the inventing company) I called an 800 number "silly me" they asked to see my plans for ALL my inventions. I sent them the plans but before I did this I had sent myself the plans through registered mail. Now, I see all the products I had sent the company coming to market. I was looking for at least a year the vacuum backpack was invented. One of the plans I'd sent, I also created the "Dish duster" rotating brush which scrubs dishes. so if you have a pattent date on it I would appreciate it if anyone has any year these products came out.
