Jon Tandler combines his analytical and creative skills to provide clients with holistic counsel.

Jon is an intellectual property, information technology, and business transactions lawyer. He has been practicing in these specialized legal fields for more than 40 years and remains passionate about his work and serving his clients.

He works with diverse clients in diverse industries, representing private companies, tax-exempt organizations and individuals engaged in technology design and manufacturing, civil engineering, aerospace, healthcare, power generation, publishing, performing arts, gallery operation, employee training, and counseling.

Clients appreciate Jon’s attention to detail and his thoroughness and responsiveness. His transparent, professional, and personable approach make communications easy and straightforward.

Intellectual Property

In his intellectual property practice, Jon emphasizes copyright, book publishing, and licensing law. Central to his book publishing practice, he represents independent publishers, distributors, packagers, trade associations, literary agencies, and select authors.

Information Technology

His information technology projects emphasize developing and procuring software applications and related technology and services for client use.

Business Transactions

Jon’s business transaction services support small- and middle-market companies with intra-company governance, contract review, and creating vendor, customer, and other commercial agreements.

His education and work in finance and experience on business transactions, informs his technical, creative, business, and practical approach to projects. His focus is tailored and responsive to the needs of each project, helping each client succeed through experienced advocacy and getting to balanced and fair agreements.

His projects are cross-disciplinary. They require (1) his knowledge in a particular substantive area such as copyright, trademark or Internet law; (2) using best practices in contracts preparation for a particular discipline, such as a publishing agreement or brand license; and (3) familiarity with the customs and practices of a specific industry such as translation publishing or engineering.

The diversity of Jon’s legal work, projects, clients, and the ongoing creativity and technical focus required of him is a natural extension of his passion for music, especially jazz, as an amateur percussionist and hand drummer.
