Key Takeaways

• PTAB requires Board approval for lead counsel changes
• Unopposed motions streamline substitution without delaying schedule
• Prompt filing and qualified replacement counsel essential
• Compliance with 37 C.F.R. §42.10 avoids prejudice
• Counsel swaps common in post‑grant review timelines

Pulse Analysis

The PTAB’s procedural framework for attorney representation is anchored in 37 C.F.R. §42.10, which mandates Board approval for any change in lead counsel. This rule ensures that parties retain qualified representation throughout a proceeding and that the Board can monitor staffing to prevent disruptions. In PGR2025‑00086, the patent owner’s unopposed request met these criteria, allowing the Board to grant the substitution without further inquiry. The order illustrates the Board’s focus on orderly case management rather than substantive patent issues.

For IP practitioners, the key lesson is the importance of timing and coordination. A motion to replace lead counsel must be filed promptly, clearly identify the incoming attorney, and demonstrate that backup counsel is available as required. When the opposing party does not object, the Board typically views the request as low‑risk, reducing the chance of schedule setbacks. Conversely, delayed or incomplete filings can trigger objections, potentially leading to procedural hearings and missed deadlines that jeopardize a client’s post‑grant review strategy.

Strategically, counsel substitutions are increasingly common in post‑grant review and other AIA proceedings, where firms often reallocate resources to meet compressed timelines. The PTAB’s willingness to approve unopposed changes provides flexibility for firms to adjust staffing without sacrificing case momentum. However, firms must maintain rigorous internal checklists to ensure compliance with the regulation, as even ministerial errors can have outsized consequences. As the patent landscape evolves, disciplined counsel management will remain a critical component of successful IP litigation.
