Analysis

Eric A Lange examines applications in Art Unit 3745 of Tech Center 3700. With 191 resolved cases, the examiner demonstrates an allowance rate of 77.5 percent. This rate provides a baseline for applicants to gauge their chances of securing a patent grant. The median days to allowance is 832, which serves as a metric for timing expectations during prosecution.

The data shows an interview lift of 12.4 percent. This indicates that conducting an interview is associated with a higher likelihood of allowance compared to the 77.5 percent baseline. Practitioners may find that the 12.4 percent lift justifies the effort of an interview to potentially navigate the 832-day median pendency. The 191 resolved cases provide a foundation for these statistics in Tech Center 3700.

The 77.5 percent allowance rate and 12.4 percent interview lift suggest an environment for collaborative prosecution. Applicants should factor the 832-day median into their long-term intellectual property strategies. These metrics from Art Unit 3745 offer a view of the examiner's historical performance.
