Cowan, Liebowitz & Latman (CLL) is recognized worldwide as a leading intellectual property law and litigation firm. It also represents clients in the areas of corporate and commercial law, advertising and information technology, customs, international cargo and regulatory compliance, real estate law, trusts and estates, and military law. The firm’s experience spans a broad range of industries and is international in scope.

The firm’s attorneys are recognized for their professional accomplishments and experience, as well as their pro bono work and community service. They are also respected adjunct professors and prolific authors and represent clients of all sizes across a broad range of industries. The boutique size of the firm, and the breadth of its practice capabilities, allows it to provide a multi-disciplinary approach in a cost-effective manner.

Main areas of practice: CLL works with both in-house corporate law departments and clients who do not have staff attorneys. The practice is both domestic and international, and includes representation of public companies, privately held entities, family-owned businesses, and entrepreneurs. It acts as general counsel or provides special counseling on particular issues, from routine matters to highly sophisticated transactions.

CLL is involved in all aspects of IP law, with key areas of specialization in trademarks, copyrights and patents. Attorneys work closely with clients to develop and protect their IP assets. It is equally well prepared to address routine matters and the most unique transactions and cutting-edge lawsuits.

CLL’s customs, international cargo and regulatory compliance practice is headed by C.J. Erickson.  This group has a satellite office near JFK International Airport, and it advises on all trade matters.  It interacts with US government officials, at agency headquarters and locally, and its attorneys have testified before Congress on pending and proposed legislative and administrative matters, and regularly appear in court on trade matters.

The firm represents both employers and employees in negotiating executive employment contracts. It is often consulted regarding an executive’s rights in terminations, from rights to severance payments to calculation of benefits. It also advises on harassment and discrimination claims, employee reviews and workplace misconduct.

The IT practice group takes a multi-disciplinary approach to IT, computer law, e-commerce, social media, domain names and the internet. Equally important, it understands and is experienced in the business and commercial issues affected by technology. As a result, CLL is able to help clients participate in today’s marketplace like few other firms.

CLL has extensive trial and appellate experience in state and federal courts and before administrative agencies. It represents clients in proceedings before the Trademark Trial and Appeal Board and in domain name arbitration actions before the World Intellectual Property Organization and the National Arbitration Forum.

CLL’s military law practice is headed by Ronald Meister, a former Navy JAG officer and military judge who represented hundreds of clients in military justice and legal assistance matters while on active duty.

The firm’s real estate practitioners assist corporate clients as well as meeting the needs of the firm’s private clients. Attorneys bring the same dedication, knowledge and skill to the acquisition of an 800-square-foot co-op as they do to the acquisition and financing of a multi-tenanted commercial building.

From time to time, clients require legal advice and assistance with personal legal issues and transactions. From real estate to tax and matrimonial matters, CLL’s attorneys provide the legal expertise, insight and care that clients have come to expect in their other business relationships with the firm.

CLL combines sophisticated tax planning experience with sensitivity and practical solutions. The focus is on preserving clients’ assets, avoiding family acrimony and, where there are closely held or family-owned businesses, planning for management and ownership continuity and succession.
