WHY SISUN LAW, PLLC?
Sisun Law is an intellectual property firm dedicated to providing strategic, business-minded trademark, copyright, patent and brand protection services tailored to the unique needs of every client. Founded and led by Scott Sisun, a former USPTO Trademark Examining Attorney, the firm draws on over twenty years of experience to deliver efficient, clear, and effective counsel across the full lifecycle of IP rights—from clearance to enforcement and litigation.
Our team of six operate with a core value of mutual respect, which underpins every client relationship. We recognize that each matter is distinct, and we work closely with our clients to offer legal guidance that is practical, proactive, and aligned with their commercial goals.
OUR SERVICES
We offer comprehensive trademark services for both foreign and domestic clients:
Foreign clients
For foreign clients expanding into the U.S., we provide expert counsel on securing federal trademark registrations, enforcing rights before the USPTO’s Trademark Trial and Appeal Board (TTAB), managing online infringement (e.g., domain disputes, social media takedowns), and initiating or defending against litigation in U.S. courts. We also assist in refining goods/services identifications to ensure alignment with new U.S. standards and market realities.
U.S.-based clients
For U.S.-based clients seeking protection abroad, we engage trusted foreign associates for national applications or coordinate Madrid Protocol filings - depending on the client’s needs, and guide brand owners through international enforcement strategies, oppositions, and brand monitoring. Our global network allows us to support brand expansion into key jurisdictions, ensuring continuity and strength in worldwide brand protection
As part of our commitment to ongoing protection, watch notices are offered as a courtesy to all clients—alerting them to potentially conflicting marks filed by third parties in the U.S. and select international jurisdictions.
