Overcoming IPR Discretionary Denial via Material Examiner Error
Patent challengers must demonstrate material USPTO examiner error to overcome discretionary IPR denial, as the Director prioritizes correcting improvident grants over settled expectations.
The USPTO Director has reinforced that demonstrating material examiner error during prosecution can outweigh Fintiv factors favoring discretionary denial of inter partes review petitions. Recent decisions highlight that overlooked prior art, misapprehended reference teachings, and abbreviated examination are persuasive grounds for institution. Practitioners should scrutinize prosecution records for examiner search deficiencies, voluminous IDS submissions, incorrect priority determinations, and allowance timing anomalies. Expert testimony mapping claim limitations to overlooked references strengthens these arguments. The Director’s emphasis on correcting examination errors aligns with the AIA’s purpose of reconsidering improvident grants, making material error a critical pathway for petitioners navigating the current discretionary denial landscape.
