Pittsburgh-based Tucker Arensberg has successfully defeated a legal malpractice claim by the former owner of a seed research and marketing company who claimed the firm had advised him that he could sell his shares in the company and begin competing using a similar name.

The state Supreme Court denied allocatur in Doebler v. Tucker Arensberg July 9, letting stand a Superior Court decision that upheld Lycoming County Court of Common Pleas Judge Richard A. Gray’s ruling dismissing plaintiff Taylor A. Doebler III’s complaint against the firm.
