Analysis

James M. Erwin examines cases in Tech Center 1700. The data includes a large sample of 602 resolved cases, showing an allowance rate of 82.2 percent. This 82.2 percent rate indicates a high probability of obtaining an allowance during prosecution. The interview lift is 5.9 percent, which suggests that while interviews provide some benefit, the high 82.2 percent allowance rate often leads to success without them. This 5.9 percent lift is a minor factor compared to the overall success rate.

The median days to allowance for these 602 resolved cases is 973. This 973-day timeline provides an expectation for the duration of the patent acquisition process in Art Unit 1700. Practitioners can use this allowance rate to gauge the likelihood of success. The 973-day median and 5.9 percent interview lift complete the profile of an examiner with a consistent track record across 602 resolved cases.
