A short-lived client relationship in Texas has K&L Gates facing conflict claims, though the litigators involved, including one who is now a clerk for U.S. Supreme Court Justice Neil Gorsuch, have already left the firm.

Quantum Materials Corp. of San Marcos filed a lawsuit against the firm in Hays County district court on Tuesday, alleging that it engaged in a conflict of interest—representing both the business and its lenders in a dispute over a loan—that caused Quantum to be sued in three states.
