That is no doubt "technically correct." If you read some well written patents, the first claim is very broad (will never be allowed). I have one on an idea I had for solving the fundamental problem* of solar thermal power. It has about 25 claims each a little more specific. The first (from memory - patent expired years ago) was something like: " (1) An apparatus for more efficiently collecting solar energy."

----------------
* Carnot limits make you want high concentration / very hot absorber, but then re radiation cuts the efficiency down as it goes as T^4.

My absorber was perfectly black (just a hole) yet had essentially zero re-radiation independent of the temperature, which was limited only by the soften point of quartz. I have given patent number in prior posts, but cannot find it easily now.

Basic idea is: concentrated sunlight enters the open end of a cylinder, which has mirror film on the outside of the cylinderical glass tube (that later grades into quartz). The light mirrors its way deeper into the tube losing less than 5 percent to the walls as heat with each reflection.

Outside of, and concentric with, this mirror tube is a simple metal tube with good external insulation. In the annulus between the two tubes the "working fluid" ** flows and gets progressively hotter the farther in it goes from the sunlight entrance end.

The deep interior is of course filled with high temperature black body radiation but as it tries to mirror back out it gets into the more glass like near entrance section and is absorbed in the glass. I.e. the IR cannot mirror its way back out yet 100% of the solar does enter and mirror to the deep interior or get absorbed as heat, which is transferred to the working fluid.

Best design has slight curve to the tube so no IR can directly escape. That proved to be too hard to analyze in the two papers I published in Applied Optics on this idea so I assumed a straight cylinder for them. Even so, the re-radiation loses were only a few percent of the 100% absorbed solar energy.

I.e. My absorber is e=1 black for entering sunlight and yet has near zero emissivity for the IR. You can almost do this also with very expensive, wavelength-selective filters, but if placed near the primary mirrors, they are too large to be economical. If place in concentrated beams near the absorber, they get very hot and crack with the first drops of rain etc.

I.e. Effectively I patented an idea I had. - I never made any model or experiments. - I just did the Applied Optics math to prove how well it would work. Papers are referenced in the granted patent.

**I noted many fluids and discussed in detail the following reversible endothermic reaction for storing high temperature heat. - I.e. make a reversible fuel & oxidizer mix from the "ash" in closed system as it is easy to separate the gas O2 and store it in tanks from the other two, modest pressure only warm liquids (mostly SO3). (They go from very hot to only warm when the burning fuel is expanded thru the power generating turbine.)

4SO3 ----> 4SO2 + 2O2 (Goes this way mainly at high temperatures)

I called my invention: "Mass flow solar absorber." You can probably find it with that title, but those old patents may not yet be indexed for computer search.
Note it is a very "green" system only sunlight in and electric power 24 hour per day out. NO exhaust (except "waste heat" all thermal engines must dump).

I was way ahead of my time. - I foresaw today's concerns 40 years ago when gas was 30 cents a gallon. Only Shell showed any interest in my invention. Soon their legal dept told their chemist to stop discussions with me, as it might some day be related to something they would invent and I could make problems for Shell. Besides, no one needed solar energy when fossil fuel was so cheap and that was what Shell's chemist should be working on. At least they did discuss - all others simply said "Not interested." (Not invented here syndrome)

Thanks to Google I found direct link to my patent issued 32 years ago and not exactly described in the prior post. See: http://www.google.com/patents?id=hM01AAAAEBAJ&dq=Mass Flow Solar Absorber

the first claim was even more general than I remembered. It was:

"1. Apparatus for facilitating energy flow, comprising: ... "

 

The idea has to be marketable/profitable in the marketplace. Otherwise you're wasting your time.

The patenting and application process will cost between $5,000-$50,000 depending on what it is. If it's marketable, you should seek financial partners, in exchange for a percentage of the idea.

Your job is to bring the idea to reality and practicality- you need to explain what it is and how it works to get a patent... you need to have a prototype.

But most importantly, you need to have something that you can prove is a new idea that works and saves time/effort/resources or is a totally original idea (that you can prove will work).

Bottom line is if you have a new recipe for butter that's 50% less everything with all the taste of butter, the promise of a truth delivered is priceless. Think: Coke or KFC's recipe.

 

These days you can do the whole patent process online, internationally. Even applying for a US Provisional patent is not the cheapest way to go, apply for a UK patent and you get a year to pay any fees and your UK Filing Date is good for your Non-Provisional US Patent. Therefore if nobody is interested in a year, just abandon your patent and it has cost you nothing. If someone is interested the royalty advance can pay the fees. A great cheap Amazon ebook which explains all this is DIY Patent Online - you can read some of it free. They also have a website but aren't trying to sell their services, just telling you how to patent without an attorney. You can bet if anybody rubbishes this comment they are an attorney.

 

I think you must have to registered your idea first in their office if that is not already have patent.I think you must ask a solicitor in your state that will help you in documentation because he know better you state laws.
