United States v. Yu Qin
688 F.3d 257
6th Cir.2012Background
- Defendants Qin and Du were indicted for conspiracy to obtain GM trade secrets, possession of trade secrets, wire fraud, and related counts; district court excluded 404(b) evidence and government appealed.
- GM documents and MTI materials on Qin's hard drive showed extensive copying of GM/GM-related files, and evidence of CPC resources used for MTI.
- Du acknowledged returning GM documents and denied improper possession; Qin operated MTI using CPC resources while employed by CPC.
- MTI pursued hybrid vehicle technology, including use of GM confidential information; CPC discovered misappropriation of CPC materials for MTI.
- The government sought to admit Rule 404(b) evidence to show intent, common scheme, and absence of mistake, which the district court excluded; appeal followed.
- The court reviews the district court’s 404(b) ruling for abuse of discretion and ultimately affirms exclusion.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether there is sufficient evidence the other act occurred | Qin allegedly appropriated CPC resources for MTI | Qin denies improper conduct at CPC | Assumed lack of definite finding; issue not decided on appeal; exclusion upheld as to this prong |
| Whether the acts are probative of a material issue other than character | Acts show intent and common scheme | Acts are not substantially similar to GM trade-secret theft | District court did not abuse; acts not substantially similar to charged offenses |
| Whether probative value is outweighed by prejudice under Rule 403 | 404(b) evidence supports intent and scheme | Evidence would mislead and confuse jury; undue delay | District court’s Rule 403 balancing within discretion; exclusion affirmed |
| Whether absence of mistake is adequately supported by 404(b) evidence | Past acts negate mistake defense | Other proof (Du’s GM certification, copying pattern) more probative | Court found better probative alternatives; 404(b) evidence properly excluded |
