There is nothing more valuable than a patent search when you have a new idea. The reason a search is so valuable is that this single step can save the average inventor a fortune. Many times you will find your invention has already been patented. If that is the case and the patent is still active, i.e. less than 17-20 years old in most cases, you will either want to change your idea or start over with a new concept. Often there is no point in pursuing an idea that has already been patented if your idea infringes the patent. Your goal as an inventor should be to seek out reasons why your invention will not work and will not make you money. This is hard for most people to understand.Different Ways To Patent Search For Inventions
