Examiner: COLLINS, DANIEL S.

Tech Center 3700 • Art Units: 3745 3753

This examiner grants 85% of resolved cases

Analysis

Daniel S. Collins has resolved 615 cases while serving in Tech Center 3700. His work within Art Unit 3745 is characterized by an allowance rate of 85.2 percent. This rate provides a statistical baseline for applicants to evaluate the probability of securing a patent grant when their application is assigned to this examiner.

The median days to allowance for these cases is 898. This figure is a key metric for practitioners to use when establishing prosecution timelines and managing client expectations. A duration of 898 days from filing to allowance suggests a specific pace of examination that should be factored into long-term intellectual property strategies.

The data also shows an interview lift of 9.4 percent. This indicates that conducting an interview with the examiner correlates with an increase in the likelihood of allowance beyond the standard 85.2 percent rate. While the lift is 9.4 percent, practitioners must decide if this improvement justifies the resources required for an interview based on the specific needs of their patent application.
