In the novels, the fictional company InGen (International Genetic Technologies, Inc. ) is based in Palo Alto, California and has one location in Europe. [nb 1] Nevertheless, most of InGen's research took place on the fictional islands of Isla Sorna and Isla Nublar, near Costa Rica. [nb 1][nb 2] While the first novel indicated InGen was just one of any number of small 1980s genetic engineering start-ups, the events of the novel and film revealed to a select group that InGen had discovered a method of cloning dinosaurs and other animals (including a quagga) using blood extracted from mosquitoes trapped in amber during various periods in time, ranging from the Mesozoic era to the 1800s. [nb 1]Beacham's Encyclopedia of Popular Fiction describes InGen as comparable to another "sleazy organization". Other sources reference the company's receiving the baby T. rex as an allusion to other exploitative entrepreneurs depicted in King Kong. Ken Gelder describes InGen as "resolutely secretive, just like the firm in Grisham's novel".
