Analysis

Examiner Spaine has resolved 8 cases in Art Unit 1617, which falls under Tech Center 1600. The allowance rate stands at 75.0 percent, indicating a favorable outcome for most applicants. However, the median days to allowance is 1014, which suggests that the prosecution process typically lasts for a significant duration. This 1014-day timeline requires applicants to be patient, even with a high 75.0 percent probability of success. Companies like Johnson & Johnson, Liquid Wood LLC, and TCI Co., Ltd. are among those who have navigated this examiner's docket.

The interview lift is 0.0 percent, meaning that interviews have not historically changed the probability of allowance in this examiner's 8 resolved cases. This lack of lift suggests that practitioners should focus their efforts on written advocacy and high-quality initial filings rather than relying on verbal conferences. Firms such as Wideband IP Office and ALSTON & BIRD LLP appear in the examiner's portfolio. Given the 1014-day median pendency and the 0.0 percent interview lift, the most effective strategy is likely a clear and comprehensive written record. The allowance rate remains a positive indicator for those willing to endure the timeline.
