Reconsidering Ex Parte Appeals: Best Practices, Strategy, Timing and Winning

View Session Speakers

When prosecution stalls or an examiner’s position becomes entrenched, an appeal can provide the mechanism needed to level the playing field and obtain a fair and objective review of the record. Indeed, ex parte appeals play a critical role in addressing the unavoidable variability that exists in patent examination at the USPTO and have quietly become one of the most important tools available to patent applicants. For many applicants, the question is no longer whether ex parte appeals are too slow or expensive—but whether they should be used more frequently and earlier in the prosecution process.

Recent developments have made the appeal pathway increasingly relevant. The discontinuation of AFCP 2.0, rising RCE fees relative to appeal costs, fewer opportunities for productive interviews following a final rejection, and a dramatic reduction in the time required to obtain a decision have all shifted the economic and strategic calculus of prosecution.

The appeal process has also become more viable in areas that historically posed challenges, including patent eligibility under 35 U.S.C. §101. The PTAB’s decision in Ex Parte Desjardins, authored by Director Squires, has reinforced the importance of properly analyzing eligibility under the current framework and has signaled a willingness by the Board to scrutinize unsupported examiner conclusions. As a result, appeals may now offer applicants a more effective pathway to challenge certain types of rejections that were once viewed as difficult to overturn.

This panel will examine when and why applicants should consider appealing rather than continuing to cycle through amendments and RCEs. Panelists will discuss strategic decision points during prosecution, how to evaluate whether a case is appeal-ready, and how appeal practice can influence examiner behavior and portfolio outcomes. The discussion will also cover practical best practices for briefing appeals, building a persuasive record, addressing common examiner arguments, and positioning cases for success before the Board.
