Celgard, LLC v. LG Chem, Ltd.
3:14-cv-00043
W.D.N.C.Feb 18, 2015Background
- Celgard, LLC sues LG Chem and LG Chem America for direct and induced infringement of the ’586 patent on lithium-ion battery separators.
- The ’586 patent covers ceramic-coated separators and polymeric micro-porous layers intended to reduce dendrite growth and thermal runaway.
- Defendants concede personal jurisdiction issues but only in Michigan; Celgard sought jurisdictional discovery and later an amended complaint adding LG Chem claims.
- Celgard amended to add claims against LG Chem (unrelated to base film supply) for unfair and deceptive trade practices, contract breaches, and unjust enrichment.
- Judge Cogburn granted Celgard’s injunction and referred pending motions, culminating in an order directing transfer consideration and later granting LG Chem’s motion to transfer venue to the Eastern District of Michigan.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether transfer to Michigan is appropriate under §1404(a) | Celgard argues firmer connection to North Carolina and patent activity. | LG Chem argues Michigan is more convenient due to its U.S. subsidiaries and witnesses there. | Transfer to the Eastern District of Michigan granted. |
