Recently, a local inventor came to me for advice because I deal with people on the Internet all over the world, understand that I operate a think tank, and they also inquired about the things they must do. I can not let you know what this special invention happens because it is such a great idea, and it is confidential. Nevertheless, I recommended that they pursue to "Google Scholar" and appearance to ascertain if other people includes a patent. First, it will not be easy to check because different industries use different buzzwords.
There could be somebody who has the patent for your exact invention and idea, almost precisely how you envision it in your thoughts, but to locate it you have to get creative and appearance all different kinds of similar words to locate it, and if it is operational you need to do need to find it. Needless to say, whether it doesn't exist, then you're lucky, you'll be able to head to second step. If someone else already includes a similar patent, see if you can find a different application for that device, or make the device in a different way. If you cannot, and they've covered all of their bases, you might desire to contact the individual, and find out if you can't make and market their product, because lots of people get a patent rather than exercise it.
In other words they never build the merchandise, never designed to, they simply wished to get the patent keep it, in case another person did, and they could get money from their website. Also, sometimes patent holders have held their patents for a number of years, or decades, they could be willing at this stage to allow you to produce their idea, for a couple percentage points in royalties. Therefore, if someone else already gets the patent, it is possible to work with them some sort of exclusive deal for a specific industry niche or application, in support of provide them with a couple of percentage points. Everyone wins.
They just license the patent to you for the specific use, so that you may start rendering it, and selling it. That's just as good right? Sure it is, and also you do not have to go get the patent, you simply need to let them have a couple of percentage points - that helps save time, since the patent process will take years, and value tens of thousands of dollars. So in this case, it might even be better. Indeed I hope you will please consider all this and think on.
FYI: Oh, one last thing, I am not a patent attorney, and you do need to execute a legal real patent search although you may don't find anything online prior to starting the patent process. You may need a good patent attorney because of this, and become very cautious about people promising a turnkey patent online, not all of them are savory characters - how do you think I am aware that? Let's just think of it as; hard knocks and experience.
