PREFACE: This book is printed in Tecumesh, Michigan with good quality paper and gloss laminated cover. There are five parts to this book. Part I (Essentials) breaks down the bulky content of the MPEP 9th Edition into a simple and easy to remember format outlining the core U.S. patent law. I emphasize materials that frequently appear in officially published patent bar exams, and also AIA materials based on both MPEP and USPTO's frequently asked AIA questions. Each topic is itemized with bullet points accompanied by notes, examples and comparisons to enhance your learning experience. The MPEP chapters are not designed in a sequence conducive to learning. This book reorders them in a logical sequence starting with chapters 200, 600, 700, 2100, 800, 1200, 1400 and 1800. These are the key MPEP chapters for passing the patent bar exam. The remaining MPEP chapters mainly require memorization. Part II (Techniques) reveals techniques for passing the bar exam. Honing these techniques will save you time and avoid costly mistakes. As a few representative examples, techniques on Process of Elimination and Time Saving Tips on Exam Date will help you manage your exam time more efficiently; and techniques on Finding Key Words in Claim Drafting Questions will help you quickly discover if a dependent claim lacks antecedent basis, or is in the alternative way, or further limits the preceding claim, or is indefinite. Part III includes 50 curated questions from published bar exams focusing on all claims drafting issues. Claims are the most important part of the patent law. A considerable number of claim related questions appear in every patent bar exam, pre-AIA and post-AIA. Part IV includes 50 frequently asked AIA Q&A questions from the latest website of USPTO. Part V includes 50 AIA multiple-choice questions that mimic the difficulties and the styles likely in a bar exam. This 5.5x8.5 travel size book, with 425 pages and wide margins for writing your own notes, provides an effective learning experience for your patent bar exam. It is a summary of my own learning experience in passing the bar exam in March 2016 on the first attempt.
