Teva's Pantoprazole Conundrum

Teva fended off Wyethe's injunction.

Teva launched at risk on Christmas eve.

Teva agreed to conduct settlement talk.

Then Wyeth launched its AG, signaling the settlement talk did not lead to an agreement.

Then Sun launched.

Then Teva announced it would not re-launch!

Was Teva bluffing? Did Teva blink first in the end?
