This examiner grants 68% of resolved cases

Analysis

David Alexander Wambst serves in Tech Center 2600 and Art Unit 2663, with a smaller pool of 38 resolved cases. His allowance rate of 68.4% suggests a generally favorable disposition toward granting patents. This 68.4% rate provides a baseline for applicants working within this specific art unit. The 38 resolved cases represent his current footprint within Tech Center 2600.

The interview lift of 50.0% is a very high figure, suggesting that interviews are extremely effective for this examiner. This 50.0% lift indicates that personal engagement can significantly sway the outcome of a case toward allowance. However, the median days to allowance of 1115 suggests that the path to a grant is often long. While the 38 resolved cases represent a limited sample, the high interview lift and 1115-day median offer clear strategic direction for practitioners seeking to expedite their applications in Art Unit 2663.
