Patent Office Post-Grant Proceedings
Strategic Advocacy in USPTO Patent Validity Challenges
Patent Office Post-Grant Proceedings provide an efficient and highly technical forum for challenging or defending patent validity before the U.S. Patent and Trademark Office (USPTO). At SJKP LLP’s New York office, we serve as associate counsel alongside leading U.S. law firms, representing both petitioners and patent owners before the Patent Trial and Appeal Board (PTAB) in inter partes review (IPR) and post-grant review (PGR) proceedings.
Although the Covered Business Method (CBM) review program has concluded, business method patents can now be effectively challenged under IPR and PGR mechanisms. With deep experience in cross-border collaboration and advanced technical understanding, our team ensures seamless representation that aligns procedural precision with technical depth.

1. Patent Office Post-Grant Proceedings Strategy and Representation
SJKP LLP combines the procedural expertise of U.S. trial counsel with the technical and analytical rigor of seasoned Korean patent professionals. Our role as associate counsel allows clients to leverage both local insight and international coordination, providing an advantage in cases involving complex technologies and multi-jurisdictional IP portfolios.
Patent Office Post-Grant Proceedings for Petitioners
We assist petitioners in developing strong invalidity positions through detailed prior art searches, claim chart preparation, and expert coordination. Our team identifies key references and arguments—anticipation, obviousness, or §112 issues—and prepares petitions that withstand procedural scrutiny and maximize institution likelihood.
Patent Office Post-Grant Proceedings for Patent Owners
For patent owners, we construct robust defenses, including preliminary responses, amendment strategies, and expert declarations that highlight inventive step and enablement. Our technical backgrounds in semiconductors, biotechnology, and software engineering enable us to craft persuasive arguments that resonate with PTAB judges.
Integrated Coordination with District Court and ITC Proceedings
We synchronize PTAB proceedings with parallel U.S. district court and International Trade Commission (ITC) litigation. This ensures consistent claim interpretation, minimizes estoppel risks, and preserves strategic flexibility across all forums.
2. Patent Office Post-Grant Proceedings and Technical Expertise
Post-grant challenges require not only legal skill but also mastery of technology and patent prosecution history. SJKP LLP’s attorneys and patent agents possess advanced degrees in electrical engineering, computer science, chemistry, and life sciences—enabling us to translate complex concepts into compelling legal narratives.
Patent Office Post-Grant Proceedings Technical Analysis and Prior Art Mapping
We conduct in-depth analyses of prior art references, file histories, and claim scope to support both offensive and defensive positions. Our team works with expert witnesses to ensure that declarations, depositions, and demonstratives are technically sound and persuasive.
Patent Office Post-Grant Proceedings and Venue Integration
When cases proceed in U.S. district courts, claim construction (Markman hearings) and invalidity contentions often mirror PTAB arguments. We align PTAB strategy with district court filings to maintain procedural efficiency and ensure consistent outcomes, mitigating the risk of contradictory rulings or duplicative discovery.
3. Patent Office Post-Grant Proceedings and Appellate Readiness
Post-grant decisions frequently proceed to appeal before the U.S. Court of Appeals for the Federal Circuit. SJKP LLP’s professionals collaborate closely with lead trial counsel to ensure continuity from PTAB petition drafting to appellate briefing and oral argument preparation.
Federal Circuit Appeals and Strategic Briefing Support
We provide appellate support in developing Federal Circuit briefs that effectively integrate PTAB records and technical testimony. Our team assists in refining claim construction arguments, procedural preservation issues, and jurisdictional challenges critical to appellate success.
Patent Office Post-Grant Proceedings and Issue Preservation
Our attorneys meticulously document procedural and evidentiary positions during PTAB trials to preserve appealable issues. This foresight ensures that clients retain strong legal footing through every stage of the dispute, from initial institution to final judgment.
4. Patent Office Post-Grant Proceedings and International Collaboration
With decades of combined experience across Samsung, the Korean Intellectual Property Office (KIPO), and the Korean Patent Court, SJKP LLP’s professionals bring a cross-border perspective to U.S. patent proceedings. We understand both the procedural nuances of the PTAB and the strategic imperatives of multinational IP portfolios.
Patent Office Post-Grant Proceedings with Global Coordination
We act as an essential bridge between Korean and U.S. counsel, ensuring effective communication, evidence translation, and alignment of technical theories. Our collaboration model supports seamless representation for multinational corporations engaged in U.S. litigation and PTAB proceedings.
