100% agree with Deborah. So after you’ve done that, you’re ready to actually start developing your idea. You’ll develop your idea on paper, make sketches, create a prototype (not an expensive one at this stage). You can use CAD drawings and 3D design to showcase the functionality of the idea.
And then you’d want to protect your idea, right? So you’ll probably want to start your patent application, maybe find a company to help you license it. This is a long process but worth it depending on your invention.
Not all inventions need to be patented but you’ll have to figure out if yours does.
Good luck!
