Patent Search

Recently I worked on some issue on patenting. Eventually it's proven to have prior art. I get more ideas and lessons about patenting. If you have a novel idea, understand what's been done before. Fifteen minutes search invested early may save hours of work. If prior exists, you want to know, sooner or later! Prior art is printed publication, public use, or product sale prior to the filing date of the patent application for the invention.
