ADAC Laboratories was a Silicon Valley medical device company specialising in nuclear medicine gamma camera manufacturing and associated nuclear medicine processing computers and software. It was originally located at 10300 Bubb Road, Cupertino, California, 95014, then as the company expanded moved in turn to the following locations. 4747 Hellyer Avenue, San Jose, CA 951, then 255 San Geronimo Way, Sunnyvale, CA, then from ~1993, 540 Alder Drive Milpitas, CA 95035. Although most people called the company ADAC or adaclabs, the name ADAC was an acronym of Analytical Development Associates Corporation. It was incorporated in California on October 14, 1970.
In the early years ADAC developed both small nuclear medicine related hardware and software products but between 1975 and the 1980s, become better known for their computer systems such as the CDS and DPS acquisition and processing systems. In 1987–88 ADAC maintained Philips ARC gamma camera installed base under licence and In ~1991 Philips exited the nuclear medicine market. At that time, the Dutch vendor licensed its nuclear technology to both ADAC and Digital Design of France". The 1990s were the dominant decade for ADAC in terms of gamma camera production, manufacturing the Argus, Genesys, Polaris, Thyrus, Transcam, Vertex, Forte and Skylight gamma cameras as well as the EPIC detector and molecular coincidence detection (MCD) option, along with the Pegasys nuclear medicine processing workstation and radiation treatment planning systems (RTP). In 1993 it was sued by Elscint for patent infringement and in 1994 purchased Philips' nuclear medicine patent portfolio, consisting of 13 U.S. patents and 56 foreign patents and patent applications. "ADAC announced it had filed a patent infringement claim against Elscint in U.S. District Court in San Jose, California, charging Elscint with violating the Philips patents. ADAC filed the lawsuit in direct response to the Elscint litigation". In 1996, ADAC was the recipient of a Malcolm Baldrige National Quality AwardMalcolm Baldrige National Quality Award 1996 Recipient. and during that year employed 720 people worldwide.
ADAC Laboratories was acquired by Philips in 2000 for $426 million, and incorporated into Philips Medical Systems (later Philips Healthcare).Philips to acquire ADAC Labs ADAC continued to operate from the Milpitas location until around 2006 and was submitting FDA pre-market filings under the company name ADAC Laboratories, Milpitas, until 2006, whereupon the 540 Alder Drive, Milpitas operation was closed and ADAC become fully integrated into the Philips organisation.
