BE CAREFUL !!!!
I have a couple of patents (electronics) and some copyrights on some tunes.
Be very wary of any and all of these organizations that claim to help inventors. They usually charge a hefty fee, and
IF they are honest, their success rate at selling inventions is typically less than 5%.
If you think you really have invented something, you can save a lot of money and heartache by doing some homework, first. The U.S. Patent Library is on line from several sources, including the Patent Office, itself. Another one is
www.delphion.com, which used to be IBM's online patent library.
Then,
you do NOT need a patent attorney. They can charge $200 - $300 per hour. I use a
patent agent, instead. Mine charges me $75 per hour. They can do everything a patent attorney can do for you,
except represent you in court in a patent suit. Hopefully, you will never get there, but if you do, that's when you need the lawyer.
You can save a lot of money by doing your own research. Go to the resources I mentioned and look up what others have done in the same area. You are entitled to interview these patent agents and attorneys at no expense to you to verify that they know something about the field of your invention. Since my inventions are electronics, I would never try to use anyone who wasn't also very knowledgable in that field, preferably a degreed electronic engineer who specializes in my particular area. Otherwise, you pay them to teach them not only about your invention, but about the whole body of knowledge surrounding it.
In 1978, my first patent cost me over $20,000, because I used a patent attorney who researched and wrote it. In 1991, my second patent cost me about $2,500, because I wrote it myself, and I used a good, knowledgable patent agent to edit it and fill in all the required forms, etc., correctly. You may not be up to writing your own, but you can still save a lot by doing your own leg work and using a patent agent.
MOST IMPORTANT -- I do not trust any of these "We will sell your invention for you" outfits.
