Class Action
Yardi RENTmaximizer Algorithmic Rent Pricing
Duffy v. Yardi Systems, Inc., et al.
Where it stands
On December 4, 2024, Judge Robert Lasnik denied the motion to dismiss and applied per se treatment to the algorithmic price-fixing claim, rejecting the argument that algorithm-mediated coordination requires rule-of-reason analysis. Case has proceeded past the pleadings.
Key ruling
December 4, 2024 (Lasnik, J.): motion to dismiss denied; 'the machinery employed by a combination for price-fixing is immaterial,' so the per se standard applies to an adequately alleged horizontal agreement implemented through shared pricing software fed with competitively sensitive nonpublic data.
