No, US companies can sue Indian companies. It doesn't need the state department. U.S. companies have sued Indian companies in Indian courts and won rulings or favorable judgments across various commercial, patent, and trademark disputes.
Famous examples include: Samsonite vs. Indian Competitors like VIP - Samsonite won the case.
Novartis vs. Indian Generic Makers. This went all the way to the Indian supreme court before Novartis lost the case. (And thank heavens for that).
Microsoft and Dell: They have won nearly all their cases in India involving unauthorized software and misuse of trademarks.
These are just the big names. There are dozens of smaller US companies.
