Exceptional Attorney Who Truly Cares and Goes Above and Beyond

I hired Susan to handle IP contracts for my tech startup, and I couldn't be happier with my decision. Her knowledge of intellectual property law is impressive; she consistently identified potential issues I never would have thought of on my own, and her advice has been invaluable in protecting my bus...iness. What truly sets Susan apart is how much she cares. She invested considerable time discussing contract details with me over the phone, making sure I understood every aspect before moving forward. She's highly responsive across phone, email, and text; I never felt left in the dark on time-sensitive questions. Her dedication goes well beyond standard business hours. On multiple occasions, Susan made herself available evenings and weekends to address matters that couldn't wait. That kind of commitment showed me she genuinely prioritizes her clients' success. As a first-time business owner navigating unfamiliar legal territory, Susan made what felt overwhelming actually manageable. She's become my go-to for all things legal, and I'd recommend her to any entrepreneur looking for an attorney who's knowledgeable, hardworking, and truly in your corner.

High-quality service and exceptional client experience

I recently had the pleasure of working with Susan Marie Dierenfeldt-Troy's law office for the finalization of a trademark registration request with the United States Patent and Trademark Office (USPTO), which was initially filed through the World Intellectual Property Organization (WIPO). The experie...nce was outstanding, and I am delighted to share my review of their exemplary services. From the onset, Susan Marie Dierenfeldt-Troy and her team took formal charge of the entire process with professionalism and dedication. They meticulously analyzed the initial application and the provisional refusal issued by the USPTO. This critical phase involved a thorough examination of the details, ensuring that every aspect of the application was scrutinized to identify areas that needed adjustments or further argumentation. What truly stood out was the attention, care, and diligence with which Susan and her team approached the task. They provided an exceptional level of service, demonstrating a deep understanding of trademark law and the intricacies involved in navigating international registration processes. Their expertise was evident in the comprehensive and well-structured arguments they presented to address the USPTO's concerns, as well as in the precise corrections they made to the application. Communication with Susan and her team was consistently clear and effective. They maintained a constant line of communication throughout the process, ensuring that I was informed of every development and next steps. I received prompt answers to all my questions and concerns, which greatly contributed to my confidence and peace of mind during the process. Overall, the service provided by Susan Marie Dierenfeldt-Troy's office was exemplary. Their professionalism, attention to detail, and commitment to achieving the best possible outcome for my trademark registration were truly commendable. I highly recommend their services to anyone seeking legal assistance with trademark registration or any related legal matters. Their expertise and dedication make them an invaluable partner in navigating the complex world of intellectual property law.
