Tonkon Torp Litigators Take on One of Oregon’s Largest Commercial Lawsuits

In 2021, Tonkon Torp defended its client Sprinklr, Inc. in one of the largest Oregon-based commercial lawsuits to be filed in recent years. The complex case between Sprinklr and plaintiff Opal Labs began in 2017 and involved the high-end technology of two sophisticated companies offering services in content marketing.

The Ramos Project

In April 2020, the U.S. Supreme Court struck down non-unanimous jury convictions in criminal cases in Ramos v. Louisiana. A shameful carryover from the Jim Crow era, Louisiana and Oregon were the last two states that allowed non-unanimous criminal convictions when as many as two jurors believed a defendant was innocent. Overnight, more than 260 cases in Oregon became eligible to seek post-conviction relief for unconstitutional non-unanimous convictions. Housed in the Criminal Justice Reform Clinic (CJRC) at Lewis & Clark Law School, the Ramos Project is a statewide pro-bono initiative providing legal assistance to those seeking redress.

The CLiF Project and Youth, Rights & Justice

It’s often the case that business attorneys shy away from justice-related pro bono work that requires appearing in court. Yet tax attorney Gwen Griffith has learned that stepping out of her lane returns value beyond measure.
