Examiner: LUSTGRAAF, BENJAMIN T

Analysis

Benjamin T. Lustgraaf is an examiner in Art Unit 1723 of Tech Center 4100. Based on 36 resolved cases, the examiner maintains an allowance rate of 58.3 percent. This rate provides a baseline for success in this technology area, indicating that a majority of applications reach a grant. Practitioners can use the 58.3 percent figure to inform their strategy and manage client expectations regarding the likelihood of a favorable outcome.

The interview lift is 21.4 percent. This data point shows that interviews are a productive tool, significantly increasing the chances of an allowance. Practitioners should utilize the 21.4 percent lift to resolve rejections and move toward a grant, as verbal engagement provides a clear advantage over written responses alone. This lift suggests that the examiner is receptive to direct discussion of technical issues.

The median days to allowance is 1250. This duration reflects the typical time required for prosecution, lasting nearly three and a half years. The combination of a 58.3 percent allowance rate and a 1250-day median provides a predictable path for applications. These metrics allow for effective planning and help in managing client expectations regarding both the outcome and the timing of a patent grant.
