This examiner grants 16% of resolved cases

Analysis

Chasity Paige Janosko, an examiner in Art Unit 1613, presents a very challenging environment with an allowance rate of only 15.9 percent. Across 44 resolved cases in Tech Center 1600, this 15.9 percent rate indicates that the vast majority of applications are rejected. This is a difficult art unit for applicants, requiring a rigorous approach to the 44 cases in this portfolio.

However, the interview lift is a remarkable 63.6 percent. This 63.6 percent figure suggests that interviews are an essential tool for overcoming the 15.9 percent baseline. For the 44 cases resolved, direct communication with Chasity Paige Janosko was the most effective way to achieve an allowance. Practitioners should prioritize interviews to leverage this 63.6 percent lift and improve their odds.

The median time to allowance is 1244 days for the successful cases. This 1244-day pendency, combined with the 15.9 percent allowance rate, means that applicants must be prepared for a long and difficult process. The 63.6 percent interview lift is the only significant factor that improves the odds of success within the 1244-day window. The 1244-day metric is a critical baseline for planning.
