Categorizing an individual act can be complex, as some national intelligence services have provided scientific and technical intelligence to private firms based in their countries. It becomes even more complex when the information is provided to an organization partially or fully owned by that government, and that organization competes in commercial markets. Other complexities arise when the information is not actually stolen, but where the foreign intelligence service (or business) buys one copy of a high-technology product, and then reverse engineers its technology to use in its own products. End user license agreements forbidding reverse engineering are common in software, but less so in other business areas.
