Ariel advises technology companies on Intellectual Property issues including strategic Patent and Trademark portfolio development, risk assessment (including invalidity, non-infringement, and freedom-to-operate opinions), investment/M&A due diligence, licensing, and IP disputes/litigation.

As a former software developer, Ariel’s technical expertise enables him to work seamlessly with clients across a broad range of technologies including cloud computing, artificial intelligence (‘AI’), machine vision, robotics, cybersecurity, virtualization, Big Data, automotive technologies, Internet of Things (‘IoT’), FinTech + Blockchain, UAVs (‘drones’), CleanTech, and medical devices. As a patent attorney, Ariel has worked closely with numerous Fortune 100 corporations and brings an insider’s perspective to the way major IP portfolios are developed, managed, and leveraged.

In addition to advising industry leaders, a significant portion of Ariel’s practice focuses on startups and mid-size companies. Geographically, Ariel’s client base spans the globe, from Silicon Valley to New York to Europe, Israel, Asia, and beyond. This unique perspective enables Ariel to effectively counsel companies at all stages of growth and help position them for future success.

Ariel also routinely counsels clients on design patent, trademark (including mark selection, registration, and enforcement), copyright (including open source compliance), and trade secret matters.

Ariel is based in New York City and is an active participant in the city’s growing tech ecosystem. For the past seven years New York Super Lawyers magazine has recognized Ariel as a ‘Rising Star’ in Intellectual Property.
