CLYDE H. BOHNSACK,

Plaintiff-Appellee, v.

VARCO, L.P.,

Defendant-Appellant.

Appeal from the United States District Court for the Southern District of Texas

Before JONES, Chief Judge, and STEWART and SOUTHWICK, Circuit Judges. CARL E. STEWART, Circuit Judge: Varco, L.P. (“Varco”) appeals from a jury verdict awarding Clyde H. Bohnsack compensatory damages and punitive damages for fraud and compensatory damages for misappropriation of trade secrets. Because Bohnsack did not prove that he was entitled to damages on his fraud claim, we RENDER a take-nothing judgment on Bohnsack’s fraud claim, and we REVERSE the jury’s award of punitive damages. Because the verdict for misappropriation of trade secrets was supported by sufficient evidence, we AFFIRM the jury’s verdict on Bohnsack’s claim for misappropriation of trade secrets.

No. 10-20741 I. This dispute is between Clyde Bohnsack, a drilling fluids engineer, and Varco,1 a company that cleans drilling fluids. Drawing on several decades of experience in the industry, Bohnsack invented the “Pit Bull,” a machine intended to make the process of cleaning drilling fluids more efficient. Bohnsack and Varco negotiated over the right to manufacture the Pit Bull for several years. After Varco pulled out of these discussions, Bohnsack sued Varco for fraud and for misappropriation of trade secrets. A jury found for Bohnsack on both claims and awarded him compensatory damages and punitive damages. We summarize the relevant facts below. The Role of Drilling Fluids. Drilling fluids serve two essential functions in oil wells: they lubricate the drill bit and carry solids back up to the surface. As a drill bit tears through the ground and accumulates earth, drilling fluids are pumped down into the well. While in the well, the fluids mix with the drilled cuttings–sand, rock, and clay–ripped up by the drill bit. The mixture of drilling fluid and drilled cuttings, referred to in the industry as drilling mud, returns to the surface through a pipe. Varco purifies drilling mud so it can be reused. After the drilling fluid returns to the surface as drilling mud that contains drilled cuttings, Varco’s machinery cleans the drilling mud by separating the drilled cuttings from the drilling fluid. The separation is done in stages by sending the mud through several machines–shell shakers, desilters, and desanders–located in tanks next to the oil rig.2

1 The defendant is referred to by different names in the Record on Appeal. For simplicity’s sake, we only use “Varco.” 2 By the time this process is complete, the drilled cuttings have gone into one tank and the drilling fluid has gone into another. The drilled cuttings are stirred and then pumped out into containers which are hauled away by dump trucks for disposal. Finally, the drilling fluid is examined by a drilling fluid specialist, who ensures that the resulting fluid can be reused.

No. 10-20741 A hitch in the process arises, however, when the particles in the drilling mud accumulate in the tanks that hold the shell shakers, desilters, and desanders. Since the mud sits in these tanks until it is ready to be transported to the next stage of the cleaning process, solids pile up in the tanks as the cuttings settle. Because tanks that contain debris cannot be moved, the accumulation of solids becomes inconvenient whenever the drilling of a well is complete and tanks must be transported to a new well. If a tank is loaded down with cuttings, workers must dig out the cuttings before the tank can be moved, at significant time and expense. The Pit Bull. To alleviate this problem, Bohnsack designed the Pit Bull, a portable pumping machine that reduces the volume of cuttings that remain in tanks after the mud passes through. The Pit Bull contains a Mission 6 x 8 pump with a sixty horsepower motor and a twin-jet designed rotating head. The invention’s jetting action causes mud to be pumped to the top of the tank through a hose, and then sends the mud back into the tank. In this way, the Pit Bull uses suction to prevent the drilled cuttings from settling at the bottom of the tank. At trial, a Varco employee estimated that each time a well is completed, the use of the Pit Bull saves workers one or two days that would otherwise be spent digging and hosing drilled cuttings out from the tanks. Beginning of Negotiations Between Bohnsack and Varco. After negotiations over the Pit Bull with one of Varco’s competitors did not progress,3 Bohnsack presented his idea to Varco on July 29, 2003. That same day, Bohnsack entered into a mutual secrecy agreement with Varco requiring Varco to keep secret all information provided by Bohnsack, and providing that such information would remain property of Bohnsack.4 Shortly after signing the first

3 Bohnsack first offered the Pit Bull to Swaco, Varco’s largest competitor. Swaco and Varco are the two largest competitors for this business, with Halliburton a distant third. 4 This agreement would be continuously renewed over the next several years.

No. 10-20741 mutual secrecy agreement with Varco, Bohnsack spent between two and three weeks working with two employees of Varco to build a prototype of the Pit Bull. The Patent Application. After Bohnsack said he was interested in seeking a patent for the Pit Bull, Varco began the process of obtaining one. On October 13, 2005, E.J. Kubena, a manager of marketing for Varco, sought permission to apply for a patent from two Varco executives: Kevin McDonough, a vice president of manufacturing and engineering, and Richard Koch, a subordinate of McDonough who was responsible for new product development. Kubena wrote, “We need to cover the device since we will probably market the unit.” He added that Varco was currently testing the unit and that Halliburton wanted four units,5 and he described the Pit Bull in positive terms: “The unit reduces overall solids content in the mud system and helps save mud by not having to dump and wash mud pits out.” In response, Koch asked if Bohnsack worked for Varco and wrote that if Varco would be the exclusive owner of the patent, Kubena should attempt to protect Varco’s intellectual property rights.6 Kubena then asked Guy McClung, an outside lawyer who frequently prepared patents for Varco, to apply for a patent for the Pit Bull. As source material for the application, McClung received from Varco a drawing and written descriptions of the Pit Bull. On October 19, 2005, McClung filed a patent application. McClung had neither seen the Pit Bull nor spoken to Bohnsack about the invention at the time he drafted the application. Nevertheless, the patent application prepared by McClung stated that, because McClung had added ideas to the drawing, McClung was a co-inventor of the Pit Bull. At this point, while the patent application had been submitted, the

5 At trial, Kubena testified that his belief that Halliburton was interested in the Pit Bull came solely from Bohnsack. 6 Bohnsack did not work for Varco. Of course, Koch likely asked whether he did because of the effect an employment relationship would have on Varco’s ownership rights in the patent.
