Major technology companies like Intel Corporation, SK hynix Inc., and Texas Instruments Incorporated are frequently seen in this examiner's docket. Firms such as Astute IP Law Group and Bridgeway IP Law Group, PLLC must navigate the 1225 days to allowance, which requires patience and long-term planning. Compass IP Law PC also manages cases within the 687 resolved cases handled by this examiner.

The 68.4 percent allowance rate provides a reasonable expectation of success, but the 3.9 percent interview lift suggests that practitioners should focus their efforts on the quality of their written arguments. Because the median days to allowance is 1225 days, any delays in prosecution can significantly extend the time to grant. Understanding these metrics is essential for firms working in Art Unit 2181.
