This book is a guide to avoiding the pitfalls of trying to patent a device that falls into the category of a perpetual motion machine (PMM). It is written by a Patent examiner with 20 years experience working for PTO (US Patent and Trademark Office).

Given the amount of time, energy, and money required to submit a patent application, this book will be extremely helpful to inventors who may not be aware that their devices will fail to qualify for a patent.

Ever since motion was invented, people have wanted to build machines where it never stops. Alas, there are many things which prevent this from happening (which we can sum up in one word: science). BUT, there are a lot of people out in the world who don’t know about this science thing, and who will believe anything anyone tells them or sort of shows them. Your job is to get this Solarbotics Perpetual Motion Marble Kit, enjoy putting it together, and then show it to these believers of bunk and convince them you’ve created perpetual motion. Just for fun.

In the last days of 1907, the German novelist and exponent of glass architecture Paul Scheerbart embarked upon an attempt to invent a perpetual motion machine. For the next two and a half years he would document his ongoing efforts (and failures) from his laundry-room-cum-laboratory, hiring plumbers and mechanics to construct his models while spinning out a series of imagined futures that his invention-in-the-making was going to enable.
