In a Thursday filing, Thelen Reid Brown Raysman & Steiner confirmed some and denied most of the allegations in a former client’s legal malpractice suit and is countersuing for $120,000 in unpaid fees.

The suit, filed June 12, alleged that Thelen failed to adequately address conflicts of interest in representing a client — Delaware-based IVI Smart Technologies Inc. and two subsidiaries — and a competitor, Michael Gardiner. The complaint also alleged that San Jose, Calif., partner David Ritchie “actively assisted” Gardiner in the repeated theft of the identity verification company’s intellectual property.
