Analysis

Ganapathy Krishnan is an examiner in Tech Center 1600 and Art Unit 1623. The examiner has a high volume of 1122 resolved cases, which provides a very reliable dataset for analysis. The allowance rate for these cases is 52.7 percent, indicating a rigorous examination process where about half of the applications result in a grant. Practitioners can use the 52.7 percent allowance rate to assess the general receptivity of the examiner to patent applications in this art unit.

The median days to allowance is 1149, reflecting the typical speed of prosecution from filing to issuance. The data also shows an interview lift of 1.0 percent, which is very low. This 1.0 percent lift suggests that interviews have a minimal impact on the likelihood of allowance with this examiner. Practitioners should focus on the quality of their written submissions, as the 1122 resolved cases show that the 52.7 percent allowance rate is largely independent of verbal communication. The 1149-day median pendency remains a key metric for planning purposes.
