FAQ
What is the format and procedure for PTAB oral argument in IPR proceedings?
PTAB oral argument follows a structured procedure with specific rules under 37 C.F.R. § 42.70: REQUESTING ORAL ARGUMENT: oral argument is NOT automatic — it must be REQUESTED; for IPR proceedings, the petitioner or patent owner may request oral argument in a MOTION filed no later than the filing of the petitioner's reply or patent owner's sur-reply (whichever is later); if the PTAB grants the request, it will schedule the argument; the PTAB may also ORDER oral argument on its own initiative when it believes argument would be helpful; FORMAT: TIME ALLOCATION: each side typically receives 20 MINUTES of total argument time; the PTAB may adjust time allocations in complex cases or for multiple patents/proceedings; PETITIONER GOES FIRST: the petitioner argues first, followed by the patent owner; REBUTTAL: the petitioner may reserve a portion of their 20 minutes for rebuttal (typically 5 minutes); this rebuttal must be reserved upfront at the start of oral argument; PANEL COMPOSITION: oral argument is heard before the same panel of THREE Administrative Patent Judges (APJs) who will decide the case; typically the lead judge opens the argument and facilitates; all three APJs may ask questions; LOCATION AND FORMAT: arguments may be held: at USPTO headquarters in Alexandria, Virginia; by video teleconference (common post-COVID); less frequently, at the Federal Circuit courthouse or other locations; EXHIBITS AND DEMONSTRATIVES: parties may file demonstrative exhibits (slides) BEFORE the oral argument; the PTAB rules require demonstratives to be filed with the opposing party by a set time before the argument (typically 7 days prior); demonstratives CANNOT contain new arguments or evidence not already in the record; RECORDING: oral argument is transcribed and the transcript becomes part of the record; arguments are sometimes audio/video recorded; NO LIVE WITNESSES: there are no live witnesses at oral argument (witnesses testify by deposition in PTAB proceedings, not live).
What restrictions apply at PTAB oral argument — what can and cannot be argued?
PTAB oral argument is strictly limited to issues already in the briefing record: THE NO-NEW-ARGUMENT RULE: 37 C.F.R. § 42.70(b): 'At the oral argument, a party may only present arguments relied upon in the papers previously submitted'; this is a hard rule — attempting to introduce new arguments is typically met with immediate interruption from the panel; NEW ARGUMENT DEFINED: parties CANNOT: introduce a new ground of unpatentability not in the petition (for petitioner); raise a claim construction argument not advanced in the written briefing; cite a prior art reference not included in the instituted grounds; introduce new experimental data not already in the record; argue that a new combination of references renders the claims obvious if that combination was not in the petition; WHAT IS PERMITTED AT ORAL ARGUMENT: synthesizing and emphasizing arguments already in the papers; responding to arguments raised in the opposing party's briefing; clarifying or reinforcing the key distinctions between competing claim constructions; directing the panel's attention to specific portions of the prior art, declaration testimony, or specification; correcting mischaracterizations of the record made in the opposing party's papers; DEMONSTRATIVE SLIDES: slides must ONLY reference evidence already in the record; a slide that summarizes an expert declaration argument is permissible; a slide that introduces a new side-by-side comparison not already in the briefing is typically challenged; THE PANEL'S ROLE: the panel often interrupts to refocus argument on specific record citations; if a party makes an argument that appears to be new, an APJ will typically say 'where is that in your papers?'; the inability to point to a specific page in the record is a strong signal the argument is new (and impermissible); ESTOPPEL CONSIDERATIONS: unlike some other contexts, PTAB oral argument does not create additional estoppel beyond what the petition and briefing create; however, CONCESSIONS made at oral argument can be used against the conceding party in the FWD and on appeal.
How should petitioner and patent owner prepare for PTAB oral argument?
Effective PTAB oral argument preparation requires specific record mastery and strategic planning: UNIVERSAL PREPARATION — FOR BOTH SIDES: (1) MASTER THE RECORD: oral argument at PTAB is won on the record; know every claim construction argument in the briefing and where each supporting citation appears; know every prior art reference by exhibit number (EX1001, EX1002, etc.); know key deposition transcript cites for both your expert and theirs; know the patent specification page and column numbers for key disclosures; (2) ANTICIPATE PANEL QUESTIONS: APJs have read the papers thoroughly before argument; they typically ask about the WEAKEST spots in your position; prepare honest, direct answers to the hardest questions; an evasive answer to a direct APJ question is worse than a concise acknowledgment of a weakness; (3) PRACTICE WITH INTERRUPTIONS: oral argument at PTAB is far more interactive than appellate argument at the Federal Circuit; APJs interrupt constantly; practice with a colleague acting as an aggressive questioner; your prepared remarks should be your secondary priority; answering questions directly is the primary task; (4) PREPARE A FLEXIBLE OUTLINE, NOT A SCRIPT: prepare the 3-4 most important points in priority order; be ready to abandon points if time runs out; the panel has already read the papers — they do not need you to recite them; PETITIONER-SPECIFIC PREPARATION: structure your argument: claim construction first (if disputed) → most decisive prior art ground → strongest obviousness motivation; reserve 4-5 minutes for rebuttal; during rebuttal, address ONLY the most important points patent owner made; PATENT OWNER-SPECIFIC PREPARATION: patent owner typically argues SECOND; you know what petitioner said at the time you argue; prioritize: best claim construction argument → why petitioner's mapping is wrong → secondary considerations evidence (if any); consider whether to split time between claim construction and substantive invalidity; DEMONSTRATIVE SLIDES: simple, uncluttered slides work best; one key claim construction comparison; one side-by-side of the claim limitation vs. the prior art disclosure; cite exhibit numbers prominently.
How do APJ panels typically use oral argument to make their decisions?
Understanding how APJs approach oral argument can help counsel focus their preparation: PTAB PANELS HAVE ALREADY READ EVERYTHING: by the time oral argument occurs, the APJ panel has read: the petition; the patent owner response; the petitioner's reply; all expert declarations and all deposition transcripts; all prior art exhibits; the patent and prosecution history; oral argument is NOT the first time the panel encounters the arguments; APJ QUESTIONS REVEAL THEIR THINKING: when APJs ask repeated, pointed questions about one issue, that issue is typically a contested or unclear point in the case; when APJs ask no questions about an issue, they have likely already resolved it; carefully tracking which issues the panel probes can signal where they have doubt; CONSENSUS vs. DISAGREEMENT SIGNALS: when all three APJs are silent on an issue, it may mean they all agree on it (though not necessarily agreeing with you); when one APJ asks aggressive questions while others are silent, the case may be divided; watch for subtle signs of agreement or disagreement among the panel; COMMON PATTERNS IN APJ QUESTIONING: CLAIM CONSTRUCTION: 'Where does the specification distinguish A from B?'; 'How would a POSITA read this term in light of column 5?'; PRIOR ART MAPPING: 'Where exactly in Exhibit X does petitioner say this element is disclosed?'; 'What is the petitioner's response to the patent owner's argument on column 6?'; MOTIVATION TO COMBINE: 'Why would a POSITA combine reference X with reference Y?'; 'Where does the petition address the teaching-away argument?'; EXPERT CREDIBILITY: 'Your expert was cross-examined on this point — what do you say about the deposition at page 47?'; HOW PTAB USES THE ARGUMENT TRANSCRIPT: the FWD may cite oral argument transcript to explain a party's position or concession; notable concessions at oral argument can appear in the FWD.
What are the most common mistakes made at PTAB oral argument?
Avoiding common mistakes can prevent an otherwise strong case from being undermined at argument: MISTAKE 1 — IGNORING APJ QUESTIONS TO FINISH PREPARED REMARKS: the most critical mistake; when an APJ asks a question and counsel says 'I'll get to that — let me just finish this point first,' the panel loses confidence; APJ questions ARE the argument; address them immediately, then briefly circle back if needed; MISTAKE 2 — ARGUING THINGS NOT IN THE PAPERS: any argument that a panel member cannot immediately locate in the briefing undermines credibility; if you cannot point to the exact page where an argument appears in your papers, you should not be making that argument; MISTAKE 3 — MISIDENTIFYING EXHIBITS: exhibit numbers matter; confusing EX1003 with EX1004 is a credibility problem; know your exhibit list cold; MISTAKE 4 — FAILING TO ADDRESS THE OPPOSING PARTY'S STRONGEST ARGUMENT: the panel has read the opposition papers; they expect you to address the opposing party's strongest point directly; avoiding it signals weakness; MISTAKE 5 — CONCEDING TOO MUCH: in attempting to be reasonable, counsel sometimes concede points they did not need to; unintended concessions can appear in the FWD; be accurate but do not volunteer concessions; MISTAKE 6 — OVER-RELYING ON SLIDES: slides are aids, not arguments; when the panel ignores your slides and asks direct questions, abandon the slides immediately; MISTAKE 7 — SPENDING REBUTTAL TIME ON MINOR POINTS: the petitioner's rebuttal should be reserved for the one or two most important points that patent owner raised; using rebuttal time on minor procedural points or restating your main argument is wasted time; MISTAKE 8 — NOT KNOWING THE PRIOR ART AT THE EXHIBIT LEVEL: when asked 'where does Exhibit 1003 disclose this element?', you must be able to point to the specific page, figure, or column; MISTAKE 9 — LOSING COMPOSURE UNDER HOSTILE QUESTIONING: a hostile question is a teaching moment, not an attack; answer calmly, accurately, and directly.
