Focus According to an article by Rudolph A. Pyatt, Jr., in the Washington Post (July 27, 1982, pp. D7-8), Pacific Scientific claims that "Rosenthal wanted to develop the analyzer for himself and that after resigning he obtained financing for research and development from a Swedish firm with which Neotec had had discussions." The near-infrared technique is not a new one. For instance, an I N S T R U -

(pp. 835-40 A). Rosenthal's Trebor90 Grain Tester differed somewhat from earlier designs, however. With earlier instruments, the grain was first ground and infrared radiation was reflected off the ground sample; whereas radiation is transmitted directly through a sample of whole grain with the Trebor-90, and grinding of the sample is no longer necessary. According to Trebor's suit, the three defendant firms conspired to steal a Trebor-90 unit to learn the trade secrets involved in its manufacture. An instrument such as this is normally protected by both patents and trade secrets. "When youtnke'out patents, all you've done is provide a track for other people to go around," said Rosenthal in a recent interview. "In other words, you've exposed your poker hand. A clever guy looks at it, and is perhaps able to come up with another way of doing the same job without infringing on the patent." Perhaps a better way of protecting yourself, explained Rosenthal, is the trade secret route, where you simply don't divulge publicly how you do something. This is the route that Coca-Cola has taken with its recipe, for instance. "Yes, we were covered by three patents on the Trebor-90," said Rosenthal, "but in addition to the patents there were a number of areas we considered proprietary. "It's not unusual for one company to buy another company's product," Rosenthal continued, "either directly or surreptitiously, and take that product apart. What's unusual in this case is that was not how it was done. A property owned by my company was, we allege, stolen and dismantled. We've taken great pains in our selling approach to try to avoid having someone purchase a unit and surreptitiously turn it over to a competitor. But in this case, we claim that an instrument owned by us and in the possession of an intermediate party was taken without permission and dismantled." Stuart A. Borman
