BioSyn is (or was) a rival company of InGen, which tried to keep up with InGen by any means necessary, including industrial espionage. The CEO of BioSyn was Steingarten. Employees of BioSyn included Raul Lopez, Sonya Durant, and Dodgson.
Through Dodgson, BioSyn was the company that hired Dennis Nedry to acquire dinosaur embryos stored in Jurassic Park, contributing heavily to the disaster. Later on, having discovered that BioSyn was behind this, InGen CEO John Hammond ordered some of his men to plant a bomb in a major BioSyn facility in retaliation.
Steingarten called and confronted Hammond over this incident, only for his opponent to rebuff his accusations.
