ChampionX LLC v. Resonance Systems Inc. (TV1)
3:21-cv-00288
E.D. Tenn.Sep 26, 2024Background
- Plaintiff ChampionX, LLC (formerly Windrock, Inc.) and Defendants (including Resonance Systems, Inc.) are engaged in litigation involving alleged use of trade secret and confidential material.
- Defendants’ expert, Dr. James Plank, previously was a party in an arbitration with StreamScale, Inc., where he was accused of improper disclosure of confidential information. The dispute settled with no admission of fault, and Dr. Plank signed a confidentiality agreement.
- During Dr. Plank’s deposition, Plaintiff attempted to question him about the details of the StreamScale arbitration; Dr. Plank, citing the confidentiality agreement, refused to answer certain questions.
- Defendants moved to exclude all evidence regarding Dr. Plank’s StreamScale arbitration, arguing irrelevance and potential prejudice. Plaintiff opposed, arguing relevance to Dr. Plank’s credibility and bias. Plaintiff also moved to reopen Dr. Plank’s deposition and sought sanctions.
- The motions were fully briefed, including procedural arguments over discovery process and protective orders.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of evidence about Dr. Plank’s prior arbitration | Relevant to credibility and bias, given similar allegations | Irrelevant and prejudicial; not related to his opinions | Allowed limited reference—arbitration is probative |
| Scope of inquiry into StreamScale arbitration | Jury should hear about it; protective order governs testimony | Inquiry is precluded by confidentiality; questioning risks prejudice | Inquiry limited to deposition testimony already provided |
| Reopening Dr. Plank’s deposition | Needed to address details of arbitration | Unreasonably cumulative, violates discovery rules | Denied; further deposition would be duplicative |
| Sanctions for Dr. Plank’s refusal to answer | Sought due to refusal and alleged discovery violations | Not warranted; issue arises from good faith privilege concerns | Denied |
