google patents - Simple and effective patent searching. Although it only covers U.S. patent documents, I highly recommend that you start your searching here. Inventor's Forum - If you are in So. Calif, attend a talk on a topic specific to inventors! Or become a member (only $50/year!) and share ideas with fellow inventors. I am the president this year and will be selecting speakers. Please let me know of any recommendations.
