Re: Whats the use for a patent??
Yes, but in the US and through my company. ALL of my comments will be in regards to US patent law. I don't know the differences between the US and Canada.
A patent for a large corporation costs about $50k. They take quite a while to get, like over a year. In the US, for small companies it's far cheaper, but it will still cost thousands.
A patent is not the right to manufacture something! It is only the right to prohibit another company from making your idea. This might seem like semantics, but it really does matter.
The first thing you need to do is get your idea written/diagrammed in a sewn notebook. Your description should be good enough that "someone schooled in the art" could recreate your invention from the patent. Sign and date it. Then take it, ASAP, to a notary and have it signed/witnessed. This is by FAR the most critical step.
After that, goto the Canadian Patent Office's website, and spend some time reading through it. The US's site is very helpful. There are also books to help private individuals through the patent process if you want some help there. After you think you're done, especially since you're interested in licensing, you probably need to talk to a patent attorney.
IMO, patents in some ways are overrated. Get your paperwork started, but really focus on getting a product made. I've met so many people so focused on the patent, and spending money on it trying to make it "ironclad", that they forget the real point was to make their invention. Even if you want to license it, you still need to make a prototype first.
