Mr. Aeolist,

As a practicing U.S. patent attorney, I get this question quite a bit. What I usually advise clients is that you should protect your invention, but you shouldn't protect it to DEATH. Your goal is to monetize your invention, and that means selling products or services. You can't sell something without showing it to people, right?

I find the best balance between secrecy and disclosure is to file patent applications for your invention, thereby starting the patent process, and then start the process of developing it, showing it around, etc. Legal work related to patents can be expensive, but you could get a provisional patent application filed for $1,500, which is affordable for most. Enforcement is another issue, which can be costly. But law firms take patent infringement actions on contingency all the time, if you have a good case. This would not cost you a cent.

I hope this helps.

Sincerely, Mark Terry, Esq.

Thank you, this was most useful.

Reach out to the angel investor community near you. Find an angel willing to give money to create a business that owns your idea and give them a share of the business. Use their money to file the comprehensive patent portfolio needed to protect the idea and defend it in court, if required. I'd guess that $50K and lots of your sweat ought to be enough to get critical patents in place.

With the patent portfolio in place, you can at leisure explore licensing the technology to major players or going into manufacturing on your own.

Going into manufacturing on your own will require additional rounds of funding - but now you quit your day job and tap the venture capital community.

Thanks. In a sense, this is what I was considering, I am just not sure how much disclosure an angel will ask for before funding an idea. I don't want to come across as paranoid in keeping my idea a secret, but I don't want to be naive and give it all away either.

Talk with a patent lawyer, generally the first consultation is free and is protected under attorney/client privilege.

Once you know roughly how much it will cost and what you would need, you can file for provisional patents (at least here in AUS, IANAL), which are much cheaper and don't end up in the public domain but do establish a priority date.

Then you can easily get any monies required to secure your patents/start work, without having to worry about disclosing too much/etc.

Thanks! This is very useful. I didn't know that a provisional patent doesn't end up in the public domain.

And even a regular, non-provisional patent application does not enter into the public domain (i.e., published on the Patent Office web site) until 18 months after you file it. In fact, you can even request that the Patent Office NOT publish the patent application at all, until it actually becomes a patent (an average 3-year wait).

Welcome. I'd be happy to help, if I can. Email me if you're interested?
