Analysis

David Earl Ogg is an examiner in Art Unit 2117 within Tech Center 4100. With 313 resolved cases, he maintains an allowance rate of 83.7%. This figure suggests that a majority of applications reaching a final disposition under his review result in a patent grant. The median time to allowance for these cases is 938 days.

While the baseline allowance rate is 83.7%, conducting an interview provides an additional interview lift of 11.4%. This increase demonstrates that even in an environment with a high grant frequency, direct engagement can further streamline the prosecution process. For the 313 cases analyzed, the interview serves as a tool to resolve remaining issues.

Practitioners navigating the 938-day timeline should consider the 11.4% lift as a means to secure an allowance. The data indicates that verbal clarification is a productive supplement to written arguments. This strategy may help maintain the momentum of prosecution toward a successful outcome.
