Legal Representation for Businesses and People with Business Issues

The Nissenbaum Law Group is a boutique commercial law firm that has been awarded the highest professional rating (AV) by the Martindale Hubbell® Rating Service.* The firm’s attorneys represent clients in a variety of areas, with a special concentration in business transactions and litigation. The transactional practice includes such matters as corporate and LLC formation, contract negotiation, shareholder issues, legal and regulatory compliance, trademark and copyright filings, commercial real estate, nonprofit law, intellectual property and sale of businesses. The litigation practice includes such matters as claims in the State and Federal Courts for injunctive relief, damage claims relating to fraud, contract breach, statutory violations, intellectual property infringement, and regulatory proceedings. The firm also has a robust practice involving matters before the NJ District Ethics Committees and the NJ Office of Attorney Ethics—and is also available to handle such matters before the NY Attorney Grievance Committee and Appellate Division—that concern investigations and hearings related to professional responsibility. In addition, it is heavily involved in Internet, entertainment, sports and leisure law, including everything from negotiating a major motion picture deal to licensing arrangements that monetize copyrighted works and trademarked images; from the legal aspects of developing video games and apps to advising an NCAA conference.

The Nissenbaum Law Group has active offices in New Jersey, New York, Pennsylvania, and Texas. However, a significant proportion of its client matters take place in other states in accordance with prevailing multi-jurisdictional rules and guidelines.
