A dispute over access to custom software and stored data between a company that monitors seismic vibrations and the tech company that built specialized software for it has been sent from federal court in Pittsburgh to federal court in Delaware.

The Pennsylvania engineering company, GeoSonics Inc., had used the tech company, Aegean Associates, to develop software that would collect data from various construction and drilling sites where GeoSonics monitored vibrations and issue reports on that data. Since the contracting relationship between the two companies started in 1990, GeoSonics paid nearly $1.3 million to Aegean for its work, according to court papers.
