Manatt Successfully Wins PTAB Appeal for ECO FIRST Co., Ltd.

Manatt Intellectual Property Protection and Enforcement Partner Irah Donner and Patent Agent Shyh-Jye Wang successfully represented ECO FIRST Co., Ltd., in an appeal before the U.S. Patent Trial and Appeal Board (PTAB) in which all the U.S. Patent Office rejections were reversed.

The invention in question is a nozzle-type steam trap capable of handling changes to the amount of discharge released from a drain. The invention can be used in a variety of facilities, including factories and offices, that use steam as a heat source to automatically discharge drains.

The Manatt team also collaborated with Harajuku Sogo, a leading global Japanese IP firm.
