As part of our ongoing effort to rank firms according to various methods in every technology center at the USPTO, we now turn our attention to TC 1700. This technology center generally handles chemical and materials engineering, with work groups as diverse as organic chemistry, metallurgy, food, and radiation imagery. Its average allowance rate is 62.7%, which is well below the USPTO average of 71%. Here, we’ve ranked the ten firms with the highest allowance rates in TC 1700. To be eligible for inclusion on this list, each firm must have disposed of at least 500 applications in the technology center in the 10-year period between 2006 and 2015.

Congratulations to the firms for their hard work and dedication in prosecuting these technologies.
