Beijing Neu Cloud v. IBM Corp., 110 F.4th 106

Beijing Neu Cloud Oriental System Technology Co., Ltd. ("Neu Cloud"), a joint venture involving IBM, alleged trade secret misappropriation against IBM entities following collaboration on developing IBM Power Systems in China.
Neu Cloud filed a federal lawsuit under the Defend Trade Secrets Act (DTSA) and, days later, a parallel New York state court action alleging various state-law claims based on the same factual allegations.
The New York Supreme Court dismissed the state action on multiple grounds, including timeliness and lack of jurisdiction over certain defendants, before the federal district court ruled on the federal claims.
The federal district court subsequently dismissed Neu Cloud's amended complaint as untimely, insufficiently pleaded, and lacking personal jurisdiction over IBM China, but did not rely on res judicata.
On appeal, IBM argued for affirmation based on res judicata, asserting that the state court judgment barred the DTSA claim, as both actions arose from the same transactions.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Does res judicata bar the DTSA claim?	Facts and evidence differ, so DTSA claim should not be precluded.	Claims arise from the same series of transactions; DTSA claim could have been raised in state court.	Yes; prior state judgment precludes the DTSA claim.
Was the state court judgment "on the merits"?	Dismissal on statute of limitations and choice of law is not a merits decision.	Dismissal on such grounds is considered a decision on the merits under New York law.	State court judgment was on the merits.
Could NY Supreme Court adjudicate a DTSA claim?	DTSA claims are exclusively federal, so could not have been raised in state court.	State and federal courts have concurrent jurisdiction under DTSA.	State court could have heard the DTSA claim.
Is personal jurisdiction over IBM China proper in NY?	Sufficient contacts with NY exist for jurisdiction.	No basis for NY jurisdiction over IBM China.	No personal jurisdiction over IBM China.
