"The incident or "midnight raid", as Ullrich referred to it, occurred on New Year's Eve 1978 as he made final preparations to go to Genentech. Seeburg, whom goodman had banned from the premises after a furious dispute in November over his ties to Genentech, asked to accompany Ullrich to remove some biological samples and take them to the company across the bay...Around Midnight, the tow entered the deserted lab and removed various research specimens, including some of Baxter's human pituitary material and a complementary DNA clone of human growth hormone" (114-115).
This literal robbery of the UCSF lab, at Midnight on New Years Eve, seems to be a very strange act by two respected research scientists. The two men claimed their acts were legal because first, they had completed the research so why shouldn't they take it with them to the new lab, and secondly they had only taken pieces of each the specimens and pituitary material. At this time, in 1978, most scientists were not working under Assignment-of-Invention agreements. This article explains what Assignment-of-Invention agreements legally mean. Because neither of the two men were legally bound to resign their research materials if they left the University, technically they were not committing a crime when they entered the lab on New Years.
