Winterfeldt IP Group is a specialized law firm focused on intellectual property issues. Based in Washington, DC, the firm also has personnel in New York and California. The firm consists of 6 lawyers and several other IP professionals with many decades of collective experience across both analog and digital platforms, including all areas of trademark portfolio counseling and management, brand-related Internet presence and enforcement such as in domain names and on social media platforms, and IP policy matters including ICANN, the new generic top-level domain (gTLD) program, and registry/registrar matters. We also advise clients on copyright, trade dress, and privacy matters, as well as IP transactions. The firm also offers a full complement of support staff with specialized IP experience, including docketing, finance, marketing, and administrative team members. Our team members participate actively in industry engagement activities, including senior leadership roles in professional associations and frequent publications and speaking engagements.

The practice has worked with over 100 companies in varied industries including media and entertainment, retail, Internet and technology, telecommunications, consumer products, pharma, hospitality, food and beverage, financial services and apparel. Winterfeldt IP Group supports its clients through a concierge-style, creative-driven and practical approach and leverages a global network of partners to build and protect IP portfolios across all international jurisdictions. While many of our clients are large national and global brands, we also have extensive experience in assisting start-ups and small businesses with designing and executing their IP protection programs.

At the core of Winterfeldt IP Group’s work are its commitments to both diversity and pro bono service, as demonstrated through our attorneys’ and professionals’ many community and industry activities. Our current initiatives devote significant time to organizations that support LGBTQ youth, minority legal professionals, persons with disabilities, and more.
