Law firms and in-house IP teams representing patent owners must respond to inter partes review (IPR) petitions challenging their clients' patents. Each response requires detailed analysis of patent claims, prior art, prosecution history, technical evidence, and legal authorities.
Attorneys, patent specialists, and paralegals work across multiple systems and documents to evaluate the petition's arguments, develop evidence-backed responses, verify citations, and prepare a compliant filing within PTAB deadlines.

What's at stake: A POPR may be the patent owner's first opportunity to persuade the PTAB not to institute review. Missing a critical claim distinction, mischaracterizing prior art, or relying on weak citations can undermine that opportunity. Thorough manual preparation is costly and limits the number of matters a specialized team can handle.
