Wilson Sonsini Secures Complete Jury Trial Victory for Via Transportation
On January 30, 2025, firm client and microtransit leader Via won a complete victory against its competitor, RideCo, following a seven-day jury trial and years of litigation in the U.S. District Court for the Western District of Texas.  After less than 3 hours of deliberation, the jury found that RideCo infringed three of Via’s patents on its virtual bus stop technology (U.S. Patent Nos. 9,562,785, 9,816,824, and 10,197,411) and ordered RideCo to pay damages, with total pretrial and ongoing damages to be determined. Via also prevailed against RideCo’s counterclaims, with the jury finding that Via did not infringe either of RideCo’s two asserted patents.
