This examiner grants 81% of resolved cases
Alexander J. Krzystan serves as an examiner in Art Unit 1799 within Tech Center 2600. The examiner has a high volume of 1136 resolved cases, resulting in an allowance rate of 81.3 percent. This high rate of approval indicates a favorable environment for applicants who can meet the examiner's requirements. The 1136 resolved cases offer a very reliable dataset for predicting how the examiner might handle similar technical subject matter.
The median days to allowance for this examiner is 1092, providing a clear timeline for the prosecution cycle. The data also shows an interview lift of 7.5 percent, suggesting that verbal engagement provides a modest benefit in resolving outstanding rejections. This 7.5 percent lift indicates that while interviews are helpful, the 81.3 percent allowance rate is the primary indicator of success. Given the 1092-day median, practitioners can develop a data-grounded approach to prosecution. The 1136 resolved cases demonstrate a consistent pattern of granting patents in Tech Center 2600.
