Examiner: DIVIESTI, KARLA ISOBEL

Tech Center 1700 • Art Units: 1792

This examiner grants 3% of resolved cases

Analysis

Karla Isobel Diviesti has a very low allowance rate of 3.4% over 29 resolved cases in Art Unit 1792 within Tech Center 1700. The median days to allowance is 1196. The interview lift of 20.0% suggests that interviews are one of the few ways to improve the chances of success, although the resulting probability remains low compared to other examiners. This profile indicates an exceptionally difficult environment for patent applicants, where the vast majority of cases do not reach allowance.

Practitioners in Tech Center 1700 should be aware of the high difficulty level, as the 3.4% allowance rate is among the lowest recorded. The 1196-day median to allowance further reflects the challenges of prosecuting cases with this examiner. While the 20.0% interview lift is a positive sign, it must be weighed against the extremely low baseline. With only 29 resolved cases, the data is limited, but the initial trend suggests that applicants will face significant hurdles. Direct communication via interviews is highly recommended to attempt to overcome the 3.4% baseline and navigate the 1196-day timeline. The 29 resolutions provide a stark warning for those entering Art Unit 1792.
