Analysis

Zachary John Baum is an examiner in Art Unit 1732 of Tech Center 1700, where he has 130 resolved cases. The allowance rate pct of 81.5 is quite high, indicating that the majority of applications reaching a final resolution result in a patent grant. This 81.5 percent rate suggests a very favorable environment for applicants seeking to secure intellectual property rights. The median days to allowance is 1076, reflecting a prosecution timeline that typically involves a significant duration of examination. This 1076-day median indicates that while success is likely, it requires a steady and persistent approach over a lengthy period in Tech Center 1700.

The data also shows an interview lift pct of 14.9, which indicates that direct communication is a beneficial strategy. This positive lift suggests that applications involving an interview have a higher probability of allowance than those without verbal negotiation. For practitioners, the 14.9 percent lift provides a tactical option to further improve the already strong 81.5 percent baseline success rate. Engaging in an interview can help resolve any remaining technical issues and potentially streamline the 1076-day median wait time. With 130 resolved cases, these metrics offer a clear view of the examiner's tendencies in Art Unit 1732. The combination of a high grant rate and a positive interview lift makes this a relatively collaborative environment for prosecution.
