Material Co. Ltd. (US) Research Institute (Senior-California), Xiaomin (Steven)
Zhang, Sun Town Technology, Inc., Global Venture Development, LLC, and Global
Venture Development, Inc. (collectively, Global Venture) (collectively, WDNC
Defendants) in the U.S. District Court for the Western District of North

practices and unfair competition, civil conspiracy, unjust enrichment and
conversion. Additionally, Celgard filed a Second Amended Complaint against
Defendants Shenzhen Senior Technology Material Co. Ltd. (US) Research Institute
(Senior-California), Farasis Energy USA, Inc., Farasis Energy, Inc., Farasis
Energy (Gan Zhou), Inc., and Farasis Energy (Gan Zhou) Co., Ltd. (collectively,

Global Venture Development, Inc. (collectively, Global Venture) (collectively,
NDCA Defendants) for patent infringement, breach of contract and breach of
implied covenant of good faith and fair dealing in the U.S. District Court for
the Northern District of California (NDCA).
The WDNC Complaint alleges the WDNC Defendants, including a former Celgard
employee, Xiaomin (Steven) Zhang, now CTO of Senior-China who changed his name
to Bin Wang at the request of Senior-China, purposely and unlawfully
misappropriated Celgard's trade secrets and confidential information and
continue to do so. Several other violations of the law are also alleged.
The NDCA Second Amended Complaint alleges the NDCA Defendants infringe
Celgard's United States Reissued Patent RE47,520 (the '520 patent), formerly
United States Patent 6,432,586 (the '586 patent), on ceramic coated separators,
and Celgard's United States Patent No. 6,692,867 (the '867 patent), on
polypropylene separators, as well as several other violations of law and
breaches. See Release. (

In December 2019, Celgard filed a First Amended Complaint in the NDCA adding to
the suit the Defendants Farasis, Sun Town, and Global Venture. See Release. (

In September 2019, Celgard filed suit against Senior who sells separators
globally that they make in Shenzhen, China. Celgard's Complaint alleges Senior
has infringed Celgard's U.S. '520 and '867 patents on ceramic coated and
polypropylene separators, and has unlawfully misappropriated and misused
Celgard's trade secrets and confidential information, among other violations
and seeks compensation for damages. See Release. (

property (IP) regarding coated and uncoated separators for lithium-ion
batteries. Celgard will continue to prevent the unfair exploitation of its
technology and IP to safeguard its assets and customers.
