Original holder of effexor patent?

Who originally held the Effexor (venlafaxine) patent?

Effexor’s active ingredient is venlafaxine. The original patent holder for venlafaxine/brand Effexor is not identified in the provided information, so I can’t state the name of the original patent owner with confidence.
