Hello! I have just read some of the patent info and it is very interesting. It is a very expensive situation to get a patent quickly. As you state, some things are stolen by others and just a small feature added and resubmitted. I was interested in getting a patent on a device I developed and contacted the patent office. This was about 30 years ago. I was informed that I could initiate a search but it would be quite expensive to go through all the material necessary to get a complete patent. Also, they provided (at that time) information on the safety of your work while in the patent search. I don't know if this (following) is still in effect or not but here is what they told me #1 DATE and Copy all your drawings, charts , photos, etc. Pack in a large manilla envelope and mail (by first class) to : INTENT TO DISCLOSURE DEPT., Bureau of Documents, Washington DC. ==== They would keep the envelope for up to 3 years while you were completing your processes. If in the case someone did try to use or steal your product, design, work, or ?? You have the oppertunity to bring them to trial and call or write the Disclosure Dept. letting them know that you needed your material. It would be returned to you UNOPENED, which you should not open until it is your time to provide evidence at the trial. Present the unopened envelope to the Judge and anything inside is proof at that date (being same as on envelope) would be proof of your property.
I hope this is of some help to anyone interested, being a newcomer I am not accustomed to all the proceedures and hope this post is not in any way obtrusive. (an no, I didn't get the patent! was too expensive at that time) The same idea came out about 15 monthe later with just a little change of my design! I had made the mistake of talking to several people while in testing the unit when I should have kept my mouth shut! Regards, Roy
