WATCH: Meet Dave Cupar

"I love innovation. Innovators hire me to develop creative IP strategies that align with their business objectives while minimizing risks and maximizing value"

Dave serves on the firm's Board of Directors and is Chair of the firm’s IP Department, where he oversees a diverse and experienced team of more than 20 attorneys, paralegals, and staff. The Department counsels market-leading companies and institutions on cutting-edge IP issues around the world. 

He focuses his practice in two key areas: 

  1. Strategic IP Solutions for Innovation Leaders: Companies and institutions who desire to be innovation leaders regularly hire Dave to identify and develop solutions that optimally align the company’s IP strategy with its overall business objectives. 
    Businesses have benefited through these strategy-based solutions in many ways, including:
    • Developing IP assets that create real value to businesses
    • Monetizing IP to increase valuation 
    • Reducing IP portfolio management costs
    • Mitigating risks of competitive IP 
    • Ceasing infringing sales and payment of damages from competitors 

  2. IP Enforcement and Dispute Resolution Strategies: Market leaders who have been wronged by domestic and foreign competitors partner with Dave to identify a sound strategy to resolve such disputes in a cost-effective, results-oriented manner. 

Dave was named "Lawyer of the Year" for Patent Law in Cleveland by The Best Lawyers in America®, 2018, and has been named a leader in intellectual property by Chambers USA since 2016.
