Mr. Lambelet is a retired engineer who became a patent practitioner in an encore career. He was involved with product development in a pharmaceutical company of the Johnson & Johnson family of companies. One of the products developed by him, Dialpak®, is a successful birth-control package now in the archives of the Smithsonian. The impulse for novelty led him to seek a license at the Patent Bar to practice as a Patent Agent of the United States Patent and Trademark Office. He has written and prosecuted patent applications for a number of clients. All patents solve problems, so this is a natural domain for Mr. Lambelet to occupy. Curiosity about unresolved problems informs several of the essays in this collection of thought exercises.
