75% – The Real Rate of Patent Applicant Success on Appeal
The biggest myth about patent appeals is that that the examiner usually wins. The Patent Trial and Appeal Board (“Board”) posts that it reverses examiners only one out of every three decisions —33%. That number is accurate, and reflects the percentage of reversals among Board decisions. But another number is more helpful — 75%. That is the rough percentage of reversals among all appeals—not just Board decisions. The difference arises because not all appeals result in a Board decision. In fact, the vast majority of appeals (80%) never reach the Board. The Board’s 33% number has nothing to say about this invisible sea of patent appeals.
