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 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.

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.
