- K&L Gates has served as a trusted legal partner across a broad range of matters, including intellectual property, patents, trademarks, commercial agreements, venture financing, employment matters, and general corporate governance. What distinguishes the firm is its ability to combine top-tier legal expertise with practical business judgment. The team consistently demonstrates a strong understanding of the realities faced by growth-stage technology companies. Their advice is not limited to identifying legal risks; they help management teams understand trade-offs, prioritize appropriately, and make decisions that balance risk management with business objectives. They are thoughtful and protective when needed, while remaining grounded and pragmatic in their recommendations. One of the firm’s greatest strengths is responsiveness and accessibility. The attorneys are highly engaged, communicate clearly, and are willing to provide guidance early in the decision-making process rather than simply reacting after issues arise. This proactive approach has been extremely valuable. Compared to other firms I have worked with throughout my career, K&L Gates delivers the legal sophistication and depth expected from a leading global firm while maintaining a level of practicality, responsiveness, and client engagement that is often difficult to find at firms of similar scale. The firm’s ability to bring together specialists across multiple disciplines and provide coordinated advice has been a significant advantage.
- Chris Centurelli has been an exceptional advisor and primary point of contact. What stands out most is his ability to combine deep intellectual property expertise with practical business judgment. He is highly responsive, thoughtful, and focused on helping clients make sound decisions rather than simply providing legal analysis. He takes the time to understand the business, technology, and long-term objectives, which makes his advice significantly more valuable than what is typically received from outside counsel. Gary Kocher has been outstanding on corporate matters, particularly with venture financing and board-related issues. He provides clear, pragmatic guidance and has a strong ability to navigate complex situations while keeping discussions focused on business outcomes. His advice has been consistently practical and well aligned with the needs of a growing technology company. James Fajkowski has been excellent to work with on patent matters. He demonstrates strong technical understanding, attention to detail, and the ability to translate complex innovations into high-quality patent filings. His work product has been consistently thorough and professional. Kathleen Burch has provided excellent support on trademark matters. She is knowledgeable, responsive, and effective at guiding matters to resolution efficiently. Kathleen Barrett has been highly responsive and professional on administrative and billing matters. She has helped ensure that engagement management and billing communications are handled smoothly and transparently. Across the team, the common themes are responsiveness, professionalism, strong legal expertise, practical business judgment, and a genuine commitment to client success. They operate as trusted advisors rather than transactional service providers, which has made them particularly valuable partners.
