Tom C. Clark,
United States v. Penn-Olin Chemical Company…
“ If the parent companies are in competition, or might compete absent the joint venture, it may be assumed that neither will compete with the progeny in its line of commerce. Inevitably, the operations of the joint venture will be frozen to those lines of commerce which will not bring it into competition with the parents, and the latter, by the same token will be foreclosed from the joint venture's market. ”
