Where to begin?!?!?!?
I work at a major research University in the Tech Transfer Office. This means I file patents, copyrights and TM's on inventions created by faculty then try to find a company to license said intellectual property.
I am not an attorney, (but have 15 that work for me) and have been doing this for over 10 years...Here are a few points to counter some of the advice above.
1) The mail yourself a letter trick is false- no such thing, a judge or patent attorney would point and laugh at you...HA HA
2)Copyright is about $35 bucks. These are for literary works, like songs and software and art. Patents can be a couple thousand if you do it yourself on
www.uspto.gov or north of $20K if you pay a $300-400 an hour Patent Attorney to file for you.
3) Public disclosure- One year rule applies in US- Foreign filing is gone unless you have filed at least a provisional application in the US before the public disclosure. A public disclosure is considered if..."one who is skilled in the art has a reasonable information to recreate or build said device". Meaning in a room full of gun nuts, someone might be able to reproduce your work based on your information as opposed to a room full of school children
4) Always have protection or PAT Pending before talking to any company. CDA is advised but they are only as good as the lawyer who defends it should they breach the contract. A Patent is designed for you to bar others from practicing your intellectual property, nothing more. If you do not or can not defend your patent, it could be considered public domain and others could use it with no $$$$ to you.
5) keep in mind what your after. Just giving a design to Ruger or Colt in exchange for what? Money? Toys? Running royalty on net sales? Are you going to front the money for the patent? Are they? Why would they need you? Research? product tooling?
6) It is a dog eat dog world in the commercial IP world. If you can afford an attorney get one, if not, read the
www.USPTO.gov and try yourself. Something like less then 10% of University patents ever make it to market, not much more for the real world I think. Over 7Million patents means not much is new out there. Do the best patent search you can to find out what you think you have and see how it is different from the rest of the patents out there.
The best thing I can suggest is read all the prior art you can. 9 out of 10 times you will find someone has allready patented it.
PS AND NEVER NEVER NEVER - EVER- go to one of those late night invent now websites or call here for $$$ on your invention. They are a scam and are not to be trusted. Really Never ever go there. bad news....
Good luck
