Because he does not have a patentable concept. No new technology and similar products already on the market are the key reasons I say that. His concept has evolved as this thread has progress, unfortunately (IMOH) it has gotten steadily worse! Initially he was simply hitting multiple keys simultaneously, now he has a whole new keyboard, which he already knows the size of, without having any idea as to exactly how many keys or what they will represent... Hmmm Horse before the cart?
He doesn't want my input anymore, so I'm just replying to Integral and others who have commented on patents.
Patentability doesn't translate into marketability. I was just on the phone a couple days ago with a friend who works as a patent attorney (I actually have two friends working in the same office, so hear a lot about patent law). He was telling me about the bizarre things that get patented (he said his clients include scientists, bad scientists, and crazy inventors, mostly the third one). You could probably get patent protection for a unique keyboard, though, it would be a very limited patent. Since keyboards exists in a variety of styles and technologies already, you can't patent the concept of a keyboard, you could only get protection on your specific configuration of a keyboard. Which means, all someone needs to do is add one more key somewhere, or take away a key somewhere, or switch around two keys, and you're not protected. This is similar to what people patent for ballpoint pens. You can't patent a pen, but you can patent a new barrel design, or a new ink formulation. Such patents are extremely limited.
If you file the patent yourself, filing it costs around $1000, which, depending on how wealthy you are, may be a drop in the bucket or a significant amount of money to spend on something that won't offer much protection. That $5000 estimate is probably what you'd pay if you went to a hack law firm, the kind that will fill out your application for you, but not help you with research or bother finding all the loopholes, etc. If you have a really good idea and want to protect the concept and get a good law firm to help with the research of prior art, write it so it holds up when you prosecute someone infringing on it, help with the technical drawings, etc, you're looking at a starting cost of $10,000 on up.
hitssquad is right that there's a risk in obtaining a patent, in that it reveals completely the mechanism of how something works, so your competitors can start working on using that idea as soon as the patent expires. Depending on who your competition is and what the market is like, sometimes it's advantageous to not patent something if it's likely to take your competitors longer to figure out how it works for themselves (business decisions sometimes involve some gambles), or to wait until you're just about ready to put it on the market before you file for protection (you're protected as soon as the filing is in, which is why a lot of things go to market labeled "patent pending"). And for some companies, patenting a new product line would reveal the gaps in protection of an already existing patent they hold, so it's better not to patent the new product and open opportunties for the competitors to jump in and use those gaps to their advantage.
There's a good lesson here about the job of an engineer too. If a client knew how to make exactly what they needed, or even knew exactly what they needed, they wouldn't need to hire an engineer to help. However, there needs to be good communication between the engineer and client to ensure what is being designed will work for what the client really wants to do with it. Sometimes you're going to get feedback that's disappointing ("No, that's just not going to work") and the client, not being an engineer, isn't going to be able to tell you what
will work, just that they know what you've shown them isn't it. It's the job of the engineer, not the client, to come up with the solution to the problem. If the engineer gets defensive and doesn't listen to the client when told things are wrong, it's going to lead to disaster. Something that may be really fun to design and build just might not be appealing in the marketplace. Isn't the continuing struggle for communication between marketing depts and engineering depts the entire basis of the Dilbert cartoons?
