Of the two ZeniMax personnel the plaintiffs called to the stand, neither Altman nor id Software Creative Director Tim Willits were VR experts. Willits, in fact, stated that he didnt write a single line of code at id Software, and Altman said, Im not a technical person. This led Wilkinson to implore the jury to weigh the credibility of the witnesses, including the often troublesom testimonies offered by Altman and ZeniMaxs computer science experts David Dobkin and Michael Gleicher. She cited the many times District Judge Ed Kinkeade had to step into the defenses cross examination and force the witnesses to give a direct answer.
The defense closed with a pointed set of responses to the ZeniMaxs allegations. Forensics expert Barbara Frederiksen-Cross found no evidence of copying in Oculus code. Both Carmack and Hollenshead stated that Oculus never got any actual source code for either the Rage VR testbed or Doom 3 BFG Edition. Early Oculus engineers stated they either never saw any Carmack source code or confirmed their code was developed independently. And every trade secret component (such as chromatic aberration correction, head and neck modeling) was already public, known, and had different solutions within the industry.
Wilkinson returned to her initial comments in closing out her argument to the jury. ZeniMaxs claims are a bunch of sour grapes, she said.
