Analysis

ELKINS, BLAKE HARRISON is assigned to tech center 1600 and art unit 1656. The profile contains 1 resolved case, an allowance rate of 100.0%, and a median of 1539 days to allowance. Interviews show a 0.0% lift in the allowance rate.

The single resolved case makes this an extremely limited record for forecasting future prosecution. That case reached allowance, but the available data does not establish a broader pattern. The interview figure provides no measured lift, so counsel should base interview decisions on the particular application and the issues presented by the examiner.

Tencent Technology (Shenzhen) Company Limited, Illumina Inc., and The Brigham and Women's Hospital Inc. are the leading companies. FOLEY & LARDNER LLP, OBLON, MCCLELLAND, MAIER & NEUSTADT, L.L.P., and 2SPL Patent Attorneys are the leading firms. These names identify the participants in the available record.
