About Marie
Marie Delapeña works in federal appellate practice and appears before the Federal Circuit. She is a practitioner who deals with the procedural and substantive challenges that arise in appeals from federal tribunals. Her work is shaped by courtroom deadlines, dense records and the oddity of federal appellate rules. She brings a methodical, case-by-case approach to that work.
Her educational background is not listed here, but her professional profile centers on appellate advocacy. Over time she has assembled a practice that files briefs, argues appeals and manages complex appellate dockets. That work requires close attention to precedent and a steady hand in drafting and oral argument.
Admission to practice before the Federal Circuit is a defining credential in her career. She is a member of the American Bar Association and holds additional professional memberships. Those affiliations provide peers and forums for the exchange of appellate practice developments and procedural guidance.
Her career path has included maintaining an independent practice under the Delapeña Law Office name. The firm operates multiple offices listed under that name. Through the firm she handles appellate filings, coordinates with trial counsel and prepares clients for the distinct demands of federal appellate litigation.
Colleagues describe her as attentive to the mechanics of appellate work. She focuses on organizing appellate records, identifying preserved and unpreserved errors, and selecting arguments that fit the appellate posture. Her tasks commonly include drafting opening briefs, preparing reply briefs, and crafting bench and court-of-appeal argument strategies.
Clients who work with her are often engaged in disputes that require federal appellate review. That can include challenges to administrative decisions, questions of federal statutory interpretation, or appeals from trial courts that raise federal questions. She works to present those matters in forms that resonate with appellate panels and adhere to the Federal Circuit’s standards.
At present she practices at the Delapeña Law Office and continues to appear in matters before the Federal Circuit. Her current work centers on federal appellate practice and appearances before the Federal Circuit.
