Analysis

PRENTY, MARK V examines in Tech Center 2800 and Art Unit 2814. His profile includes 740 resolved cases, a 91.4% allowance rate, and a 780-day median time to allowance. The interview lift is 2.1%, a small positive association that does not materially change the broader picture of frequent allowances.

The leading companies are Samsung Display Co., Ltd., United Microelectronics Corp., and TCL Technology Group Corporation. The listed firms are Innovation Counsel LLP, NORTH AMERICA INTELLECTUAL PROPERTY CORPORATION, and LADAS & PARRY LLP.

The data favors a direct prosecution approach centered on well-supported claims and efficient responses. Interviews may help with discrete questions, but the limited lift suggests that counsel should not rely on them as the primary driver of outcome. The median timing still warrants attention in portfolio planning.
