Houston intellectual property and trial firm Matthews, Lawson, McCutcheon & Joseph has sued former lawyer Erik Osterrieder, alleging the patent attorney “stole and secreted off-site in his personal law firm” confidential client information, and in one instance took a client’s information and then set that client up to be represented by his personal firm.

Matthews Lawson alleged in a petition filed March 23 in the 164th District Court in Harris County, Texas, that Osterrieder operated his own firm, Osterrieder LLC, from his office at Matthews Lawson and other locations while employed full time at Matthews Lawson. The firm, which is also called MLMJ, alleged that Osterrieder denied on at least two occasions in 2016 that he was operating his own firm while at Matthews Lawson.
