In this book I narrate what other patent experts don't tell you before patenting your invention, so you don't invest in a long and expensive process that ends in a result that is very different from what you should expect or what they told you. I will not bore you by giving you theoretical explanations of the Patent Law, this book is practical, handy, direct and explains in a pleasant and easy-to-understand way whether or not it is convenient for you to patent your invention. In less than 30 minutes you will have all the necessary knowledge to decide whether or not to undertake a process that usually takes months or even years of dedication and effort before making a profit. My professional career of over 29 years in which I have been advising inventors in the field of Industrial Property at an international level; PCT, WIPO, USPTO, CHINA PATENTS AND TRADEMARK OFFICE, EPO, etc., allows me to have the knowledge to solve doubts, concerns and some false beliefs that inventors have about what a patent is and what can be patented, while this experience has also allowed me to explain in a practical and infallible way the most important things that you should know so that you don't waste your time and money with your invention or, on the contrary, this book will help you to decide to file a patent and take advantage of your ingenuity.
