Oregon antitrust laws are laid down in Chapter 646 of Title 50 in Oregon Revised Statutes.  Private action is permissible.  Period of limitation is four years in general, and one year in certain cases according to ORS § 646.800.  One year limitation is applicable in cases where there was already an action conducted by the state.  The private party should file the suit within one year of the conclusion of the case by the state.  Under ORS § 646.770, both private person and state will be granted reasonable attorney fees, expert’s fees, and investigative costs.  Some provisions of the Oregon antitrust laws are stated below:

ORS § 646.800 reads in part:
