Patent Attorney Directed Search
Going through a lawyer to search patents will cost the least amount of time and the most money. Patent attorneys employ professional researchers. You hire the attorney, and the attorney gets someone to conduct the search. Then the attorney adds a mark-up to the search bill, sometimes as much as several hundred percent. Many lawyers cloak this in the term handling fee. To save this extra expense, some inventors hire their own researcher or do the search themselves. Most patent attorneys don't render an opinion based on a search conducted by anyone other than their own searcher. However, you can tell a lawyer that if they won't accept the work of your search firm, or searches done by yourself, you will go elsewhere where such work would be acceptable. If you're paying the bills, and you're willing to take the risk, the lawyer shouldn't have a problem. Now, if the search results show no prior art in my field of invention, you don't need an attorney to tell me the coast is clear. Conversely, if a search reveals prior art that's spot on your invention, you don't need an attorney to tell me my idea has been done before. You might, on the other hand, hire an attorney to help end-run an existing patent through the use of language in the application. If you hire a lawyer, get a quote in advance. The fee will be based on how all-encompassing you want the search to be.Patent Myths
Patents are valuable - Patents may have commercial value but that usually depends upon how it has been used. A patent means the invention works as verified by the government - The U.S. government does not test inventions to see if they work. A patent gives the owner the exclusive right to make, use, and sell the invention - A patent gives its owner the right to EXCLUDE others from making, using, and selling exactly what is covered by their patent claims. A holder of a prior patent with broader claims may prevent the inventor whose patent has narrower claims from using the inventor's own patent. A patent right is exclusory only.how to find out if an idea has been patented

One of the undying myths of Patent World is that there is such a thing as a Poor Man's Patent. If you've never heard of it, the poor man's patent involves writing out a description of your invention and mailing that description to yourself. The transmission of this description through the mail and the cancelling of the postage by the Post Office is supposed to establish a date of invention for you. That way if someone steals your invention or comes along and invents it independently, you have "proof" that you invented it first. The proof is in the sealed envelop and the date the postage was cancelled.The Main Reason Why
You have to do (or hire someone else to do) a patent search before investing in the cost of patenting . Even if you hire someone else to do the patent search for you and that is highly recommended for beginners - do a preliminary search yourself and bring that research to the intellectual property attorney or agent that you hire . Doing so will save you money, plus provide the other benefits mentioned above.
