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.

Quantum Materials, a company that manufactures tetrapod quantum dots for use in lighting applications, alleges in its petition that it engaged K&L Gates as counsel in 2016 to do corporate work, including drafting documents for a prospective lender. The company later shifted that legal work in-house, but maintains in the petition that K&L Gates never formally resigned from the representation and still remains legal counsel to Quantum.
