The court's Judgement in favor of Celgard not only granted the injunction
against Senior, it also held that Celgard had established a serious issue to be
tried that Senior had used its trade secrets in developing and manufacturing
battery separators and that England was the proper forum for the importation
dispute. Celgard intends to fully pursue its trade secret case against Senior.
On April 30, 2020, Celgard filed an application for an urgent injunction
against Senior in the High Court of Justice in London, England. On May 7, on an
ex parte basis, the UK court granted an interim injunction to prevent Senior
from importing certain battery separators into the UK.
Earlier, on March 2, Celgard filed a Complaint against Defendants Shenzhen
Senior Technology Material Co. Ltd. (Senior-China), Shenzhen Senior Technology
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
Carolina (WDNC) for trade secret misappropriation, unfair and deceptive trade
practices and unfair competition, civil conspiracy, unjust enrichment and conversion.
Additionally, Celgard filed a Second Amended Complaint against Defendants
including Shenzhen Senior Technology Material Co. Ltd. (US) Research Institute
(Senior-California) and others (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), and Celgard's United States
Patent No. 6,692,867 (the '867 patent).
