Terry L. Musika, 64, a native of Coatesville and an expert on intellectual property damages who qualified for the 1972 Olympic Games in Munich as a sprinter, died of pancreatic cancer Tuesday, Dec. 18, at his home in Hunt Valley, Md.

Mr. Musika was a cofounder of Invotex, a Maryland company that specializes in accounting, financial consulting, and intellectual property management services.

Mr. Musika was involved in some of the largest patent verdicts and settlements in the country. He served on Apple's team in the recent $1 billion verdict against Samsung, and was an expert witness for NTP Inc. in the $612.5 million agreement with Research in Motion Ltd. to settle the 2002 BlackBerry patent suit.

Mr. Musika was born in 1948 in Coatesville, son of Michael and Olamae Musika. He attended Coatesville schools and graduated from Hargrave Military Academy in Chatham, Va.

He attended Indiana University, where he was a walk-on on the track team, competing in the 400-meter run. He was an All-American and won the Big Ten Championship in the 400 meters in 1970.

Mr. Musika qualified for the 1972 Olympics in that event, but did not compete, said his wife, Sharyn. He competed in the Penn Relays several times, she said.

He earned a bachelor's degree in history in 1970 and a master's degree in public administration in 1974, both at Indiana.

In 1972, he married Sharyn Frankel, a schoolteacher whom he met while he was working as a substitute teacher in Los Angeles. The couple had three children. They settled in Hunt Valley, a suburb of Baltimore.

Mr. Musika was an accountant for 35 years, working for Peat, Marwick & Mitchell and Coopers & Lybrand/PricewaterhouseCoopers. He started several companies before cofounding Invotex in 2006.

"He had very high principles in business and in his personal life," his wife said. "He was a wonderful husband and father."

Mr. Musika also coached his children's baseball, softball and soccer teams. He was a gardener and enjoyed fishing, hiking, and playing the piano.

In addition to his wife and mother, he is survived by a son, Michael; daughters Ally and Jennifer Riemer; and a brother and a sister.

A memorial service is being planned for January.
