My dad invented a purifying water appatatus using solar energy, i want to search if it was invented before?
Question:
Answer:
Really? well, that's some intelligent dad you've got there, I don't think it was invented before but if it had then I don't think it would be in the same way because different people have different ways. I think you should present it to some big company, you will get lots of money. I would've told you which company to go to if I knew which city you live in but I don't know so oh well.
Go directly to the patent office and apply for a U.S. patent on the design. If anyone else gets it before you do that you could lose all of the commercial rights. The patnet Office will let you know if it is a new design or not.
There are already numerous apparatus to do that. Chances are, it's already been done.
hi sounds interesting, there are no cheap commercial ones available, so if you can turn seawater into cheap drinking water why not, it would certainly be appreciated in Australia.
Inventions like this are hard to get off the ground,
I have an invention that heats and cools the house provides hot water and provides electricity to the house for much cheaper than solar panels as long as there is a steady supply of seawater & solar heat.
Also my solar system uses all the sun hours of the day. Instead of just the peak 4 hours.
but I am finding it too difficult to find patent help or to sell it to a company without a large prototype.
Especially with technology that is awaiting to be embraced by the market such as your solar sea water purifyer may actually stunt the release of an invention like yours as there are so many people looking to steal the idea or make large capitals off the idea.
You will probably find yourself spending more time in court than making money from the invention which is the sad reality with todays international copywrite laws.
I have become so frustrated trying to find a way to patent my invention and the costs involved and people trying to steal it.
I have decided to put it on hold despite there being an obvious market for the product and demand in solar energy efficency and price reduction.
This is also despite the fact I now know other people are about to breakthrough with the idea as with many great inventions many people all over the world invent a similar invention at the same time, which is what you may sea with your sea water purifyer.
Maybe your dad has a lot of money and time to bring it to the market.
I would have a look through google patents to see if anything has been patented that is similar.
I am also studying Renewable energy at school so any questions ask me about it....
I have. I let the sun evaporate sea water and collect the pure water as it falls as rain!
I work in patents and I can assure you that it has been done before. In fact a cousin of mine had a solar water still way back in 1977. You can still get a patent if you can show on paper at least that the system has some advantage or distinction from existing systems.
Some of the existing systems though are pretty good. One Australian man has put together system that gets big production by stacking the units. It also has iron free glass so the solar UV sterilises the water. I am not giving anything away here, it was on the radio a few weeks ago.
Here is the search page of the USPTO. It is not particularly user friendly but you can work it out if you persist.

Here is the home page of the European Patent Office -

You already have the URL for Google patent.

Solar water stills may be classified as C02F 1/14 in the International Patent Classification (IPC). The US as usual, is the only one in step and does not use this system. You may be able to find the US classification if you can get a concordance from the IPC to the US system.

If you put C02F 1/14 into some of the search fields on these sites you will get a list of patents that have been classified under that. While the USPTO does provide for the IPC, their classification into the IPC, if and when it is done is not very reliable.
