Patent Appeal Counsel for Federal Circuit Matters
When a patent dispute reaches the U.S. Court of Appeals for the Federal Circuit, the appeal often turns on issue preservation, standards of review, claim construction, damages proof, injunction posture, and the record built below. Keyhani LLC represents patent owners and accused infringers in Federal Circuit appellate matters tied to patent litigation and related patent proceedings.
Federal Circuit Admission
Darius Keyhani is admitted to the U.S. Court of Appeals for the Federal Circuit and the U.S. Supreme Court bar.
Patent Litigation Record
The firm's appellate work is grounded in 20+ years of IP litigation experience and 80+ federal cases as lead counsel.
NJ, NY Metro, and DC
The firm serves clients with patent disputes connected to New Jersey, New York Metro, Washington, DC, and federal forums nationwide.
Litigation Only
The firm focuses on IP litigation and appeals, not patent prosecution, patent portfolio work, or trademark registration.
Federal Circuit strategy should start before the appeal is fully formed.
The practical question is not only whether the lower tribunal was wrong. The question is which issues were preserved, which standard of review applies, whether the record supports the requested remedy, and whether the appeal advances the client's business objective.
Appeal issues that need disciplined Federal Circuit framing
Patent appeals are selective. A strong appellate presentation identifies the issues the record, standard of review, and available remedy can actually support.
District-court patent judgments
Infringement, invalidity, damages, injunction, fee, and post-trial rulings can move from federal district court to the Federal Circuit when final judgment or an appealable order exists.
Claim construction and Markman issues
Claim construction often drives infringement and invalidity outcomes. Federal Circuit review depends on whether the dispute turns on legal interpretation, factual findings, or both.
PTAB or agency-source appeals
Patent appeals may follow certain PTAB final written decisions or agency determinations. The appellate matter is distinct from conducting the underlying proceeding.
Expert and damages rulings
Expert admissibility, reasonable royalty proof, lost profits, apportionment, and post-trial damages rulings can shape both appeal and settlement posture.
Injunction and remedy questions
Preliminary or permanent injunction issues can affect launch plans, product access, commercial relationships, and appellate urgency.
Appellee defense strategy
Defending a favorable judgment requires preserving alternative grounds for affirmance and preventing the appellant from reframing the record.
Keyhani LLC handles Federal Circuit appellate strategy tied to patent litigation and related patent proceedings. Patent prosecution, portfolio management, administrative patent trials, and agency investigations are outside the firm's litigation service described here.
Standards of review often decide how the appeal should be argued.
Federal Circuit appeals are not just second chances to relitigate patent issues. The standard of review shapes which arguments can realistically move the panel.
Legal claim-meaning conclusions receive de novo review, while subsidiary factual findings receive clear-error review under Teva.
Affects whether the appeal should emphasize intrinsic evidence, factual findings, or both.
The Federal Circuit's patent jurisdiction is tied to statutory paths such as 28 U.S.C. section 1295.
Affects where the appeal goes, what order is appealable, and when the appeal must begin.
Civil district-court appeals generally run under Fed. R. App. P. 4, while USPTO appeal timing has separate rules including 37 C.F.R. section 90.3.
Affects the filing calendar, forum of first filing, and any rehearing or post-judgment timing analysis.
Arguments, objections, expert challenges, and remedy positions generally need a record below before they can be useful on appeal.
Affects which arguments are worth presenting and which should be left out.
From trial record to Federal Circuit strategy
Keyhani LLC approaches patent appeals from the record outward. The work starts with the judgment, orders, claim construction record, dispositive motions, expert rulings, trial record if applicable, and preserved objections.
Identify appealable rulings and deadlines
The first step is confirming the source of the appeal, the order or judgment at issue, the filing path, and the deadline that controls.
Map preserved issues to standards of review
Claim construction, summary judgment, expert admissibility, damages, injunctions, and post-trial motions each carry different appellate posture.
Select the arguments the record can support
The strongest Federal Circuit brief is rarely the longest list of complaints. It is the set of issues the record and remedy can carry.
Align the appeal with the business objective
Appeal strategy should account for enforcement goals, defense exposure, settlement leverage, license posture, launch timing, and injunction risk.
Federal Circuit experience supported by patent litigation context
Federal Circuit patent appeals benefit from counsel who understands both patent doctrine and the litigation record that created the appeal. Keyhani LLC serves clients from its Washington, DC office in matters connected to New Jersey, New York Metro, Washington, DC, Northern Virginia, and other federal forums where appropriate appearance procedures support the matter.
Darius Keyhani
Founder and principal attorney Darius Keyhani has 20+ years of IP litigation experience, 80+ federal cases as lead counsel, Federal Circuit bar admission, U.S. Supreme Court bar admission, and an LL.M. from NYU School of Law. The Supreme Court credential is an appellate credential and bar admission, not an argument or outcome claim.
Federal Circuit appeals need judgment about what not to argue.
Patent appeals often contain many possible issues. The appellate work is deciding which issues can carry the appeal, which issues support settlement leverage, and which issues distract from the best record-based argument.
Preserve credibility with selective arguments
The brief should focus on the strongest reversible issues instead of turning every disappointment below into an appellate point.
Connect the record to the remedy
The panel needs a clear path from error to reversal, vacatur, remand, affirmance, or modified relief.
Use appeal posture in business decisions
Federal Circuit posture can affect settlement, licensing, injunction risk, product plans, and enforcement leverage.
Federal Circuit Patent Appeal FAQ
These questions usually need answers before a business decides whether to appeal, defend a judgment, or use appeal posture in settlement strategy.
When should appellate counsel be involved in a patent case?
Appellate counsel should usually be involved before the notice of appeal if claim construction, summary judgment, expert rulings, injunctions, damages, trial objections, or post-trial motions may shape the appeal. The strongest Federal Circuit issues are often preserved before final judgment.
Does Keyhani LLC represent both appellants and appellees?
Yes. Keyhani LLC can evaluate Federal Circuit posture for parties seeking reversal and for parties defending a favorable ruling. The analysis differs, but both roles require attention to the record, the standard of review, and the remedy available on appeal.
Can a PTAB final written decision lead to a Federal Circuit appeal?
Yes, certain Patent Trial and Appeal Board final written decisions can be appealed to the Federal Circuit. That does not make the underlying PTAB proceeding the same as the appellate matter. The firm evaluates these as Federal Circuit appellate issues tied to patent litigation posture and record preservation.
Does Keyhani LLC handle patent prosecution?
No. Keyhani LLC is focused on IP litigation, enforcement, defense, and appeals. Patent prosecution, patent application work, trademark registration, and portfolio management are outside the firm's litigation practice.
Federal Circuit strategy connects to the underlying patent litigation.
Patent appeals are strongest when appellate judgment is connected to the underlying claims, defenses, forum, remedies, and trial record.
