In re Edelson, Leon Irwin, 2012PR00082
Disposition Suspension for a specified period of time and until further order of the Court
Effective Date of Disposition 09/25/2013
End Date of Disposition
Definition of Disposition A suspension until further order of the Court reflects a determination that the lawyer has engaged in misconduct and that the misconduct warrants an interruption of the lawyer's authority to practice law during the suspension period, which is a fixed period of time identified in the Supreme Court's order and until the lawyer has demonstrated rehabilitation, good character, and current knowledge of the law in a subsequent reinstatement case. The lawyer is not authorized to practice law during the period of the suspension.
Case Summary Mr. Edelson, who was licensed in 1988, was suspended for three years and until further order of the Court and until he makes certain restitution. He neglected four patent and trademark matters for a client and made misrepresentations to that client about two of the matters he was handling for him. Mr. Edelson also made false statements about what he did on behalf of the client to the United States Patent and Trademark Office during its investigation into his conduct.
