Opinion

MICHAEL DEUTSCH, No. 1:19-cv-281-KES-SKO Plaintiff, v. FINDINGS OF FACT AND CONCLUSIONS OF LAW (Doc. 80) Defendant. Plaintiff Michael Deutsch brought this action against defendant Douglas Cook following the parties’ unsuccessful business venture to develop and market the “Dialfan” medical device for use in hernia surgeries. The parties tried the case to the Court in a bench trial on Deutsch’s two causes of action: unjust enrichment (quasi-contract claim for restitution) and quantum meruit. See Doc. 80; Doc. 71; Doc. 26 (First Amended Complaint (“FAC”)). Following trial, the parties submitted proposed findings of fact and conclusions of law and responses thereto. Docs. 86, 87, 88, 89. The Court sets out below its findings of fact and conclusions of law. See Fed. R. Civ. P. 52(a)(1). 1. Cook is a medical doctor. In late 2007 or early 2008, Cook began practicing as a general surgeon in California’s Central Valley. Doc. 85 (“Trial Transcript” or “Tr.”) at 169:14–18. 2. Cook invented the Dialfan medical device out of frustration with existing hernia repair techniques. Tr. 171:8–172:21; Doc. 71 (“Second Pretrial Order”), Undisputed Fact 1. 3. The Dialfan device consisted of a placement tool to be used with a mesh patch in performing hernia surgeries. The placement tool consisted of adjustable blades and a control to move the adjustable blades from a clustered position (in which the blades are stacked on top of each other, thereby allowing the blades to be inserted through a small opening in the mesh patch), into an expanded position (to spread out and apply the mesh patch evenly).1 See Second Pretrial Order, Undisputed Fact 2. 4. Cook initially paid engineers to develop technical drawings of the Dialfan. Tr. 174:6–23; Tr. 174:24–175:4. Cook then had a few metal prototypes of the Dialfan manufactured by a local machine shop. Tr. 176:13–18. 5. With his employing health network’s approval, Cook subsequently used the Dialfan prototypes in hernia surgeries on patients. Tr. 176:15–17, 177:18–178:4. In late 2009 and early 2010, Cook successfully performed approximately 20 surgeries using the metal Dialfan prototypes. Tr. 178:7–9, 179:12–13. 6. To use the metal Dialfan to apply mesh in surgery, Cook modified a mesh produced by a company called Atrium by cutting a slit in the top of the mesh to allow for the insertion of the metal Dialfan blades. Tr. 182:19–184:3. 7. The Atrium mesh, with the modifications that Cook made, was the only mesh that would work with the Dialfan. Tr. 182:25–183:3, 184:2–3. 8. Because Atrium later went out of business and no longer produces the mesh that Cook modified for use with the Dialfan, Cook no longer uses the Dialfan in surgery. Tr. 182:25–183:3. 9. As of late 2009, Cook had incurred all costs spent to develop the Dialfan, in addition

1 Though the parties at times refer to the Dialfan as consisting of both the mesh and the placement tool device (see Second Pretrial Order, Undisputed Fact 2), they most frequently use the term “Dialfan” to refer to the placement tool only and refer separately to the mesh. Following the parties’ usage, these findings of fact also generally refer to the Dialfan tool and the mesh as to using his own time. Tr. 174:19–175:15, 176:11–177:14. 10. In late 2009, a colleague suggested that Cook connect with a medical device company owner, Deutsch, to discuss further development of the Dialfan. Tr. 31:24–32:14, 179:17–180:3. Deutsch markets and sells medical devices through his company Starsurgical. Tr. 6:20–7:4; Second Pretrial Order, Undisputed Fact 3. 11. Cook and Deutsch spoke, and Deutsch then traveled to California to observe Cook using the Dialfan in surgery. Tr. 32:18–33:25, 181:22–182:12; Second Pretrial Order, Undisputed Fact 3. Deutsch met with Cook and observed Cook perform multiple hernia surgeries using the Dialfan. Tr. 34:1–2, 34:17–21, 182:10–12; Second Pretrial Order, Undisputed Fact 3. 12. The parties had conversations in which Cook said the two “should work together” given Deutsch’s experience, and the parties discussed the arrangement between them to commercialize the Dialfan. Tr. 34:9–11, 36:6–11; see also Tr. 182:1–186:25. Cook and Deutsch ultimately agreed to collaborate to commercialize the Dialfan. Tr. 181:5– 6, 185:2–11, 210:12–15; Second Pretrial Order, Undisputed Fact 4. 13. Deutsch acknowledged that these conversations led to “a partnership” or “a joint venture” in which they would “share in the Dialfan.” Tr. 36:12–13, 37:7–12, 64:2–18, 65:1–13, 88:24–25, 89:7–9, 108:9–10, 112:3–114:22, 116:1–117:1, 119:15–120:4, 123:16–18, 124:25–125:1, 133:18–134:4; see also Tr. 186:13–25. 14. The two agreed that they would share the risks and rewards, which included potential profits and losses, with Cook maintaining a 51% interest and Deutsch having a 49% interest. Tr. 37:12–21, 112:3–114:22, 116:23–117:1; Second Pretrial Order, Undisputed Fact 6; see also Tr. 186:18–19; Tr. Exs. JX-1, JX-2. 15. Deutsch never requested, and Cook never agreed to, any payment for Deutsch’s services related to Dialfan apart from him having a 49% interest in any potential profits. Tr. 114:23–25, 206:14–20. 16. The parties did not agree on a termination date for the attempt to market the Dialfan and no performance metrics or deadlines for achieving sales goals were set. Second Pretrial Order, Undisputed Fact 10. 17. At some point, Deutsch advanced $45,000 to the parties’ venture on an interest-free basis. See Trial Exs. 17, 65 at 1; Second Pretrial Order, Undisputed Fact 8. 18. The parties engaged in negotiations through counsel to formalize their business relationship, resulting in two final draft documents: (1) a Shareholder Agreement defining their relationship and ownership percentages, and (2) a Subscription Agreement detailing their respective capital contributions. Tr. 88:6–14, 115:6-117:1, 117:2–11, 119:15–120:4, 186:1–2, 186:11, 186:18–19, 187:22–23; Trial Exs. JX-1, JX-2. These agreements reflected the parties’ understanding of their oral agreement. Tr. 89:10–11, 90:15–21, 115:6–117:1, 117:2–11, 119:15–120:4, 186:1–11, 186:18–19, 187:22–23. 19. Cook signed both the Shareholder Agreement and Subscription Agreement, but Deutsch did not execute either document. Tr. 88:19–89:4, 186:11–12; Tr. Exs. JX-1, JX-2; Second Pretrial Order, Undisputed Fact 7. While Deutsch did not sign the documents, he acknowledged at trial that he believed the parties already had an oral agreement to the same effect as the Shareholder Agreement and Subscription Agreement and that there “was no need to use” the documents. Tr. 89:10–11, 90:15– 21, 116:23–25.2 20. The parties brainstormed about how the venture should proceed, “discussed things openly,” spoke frequently regarding what each “discovered for the week with the people [each] talked to, and had an “exquisite working relationship.” Tr. 102:23–24,
