Patent Litigation Counsel for Federal Court Disputes
Keyhani LLC represents patent owners and accused infringers in federal district court patent disputes, settlement strategy, trial posture, and Federal Circuit preservation. The firm is a litigation-only IP boutique with 20+ years of IP litigation experience and 80+ federal cases as lead counsel.
Federal Patent Litigation, Not General IP Advice
Patent litigation can determine the value of a technology business, product line, licensing position, or defense strategy. Keyhani LLC treats the dispute as a federal litigation problem from the first review.
District-Court Litigation
Claim construction, accused-product facts, expert strategy, damages, settlement posture, and trial preparation.
Both Sides
Representation for patent owners enforcing rights and businesses responding to infringement allegations.
NJ, NY Metro, and DC
Federal patent matters connected to New Jersey, New York Metro, Washington DC, and forums where appearance is available.

Patent disputes and court-focused strategy. Patent prosecution is outside the firm's litigation practice.
Patent Matters Keyhani LLC Handles
The patent litigation parent connects active dispute buyers to the correct next path while keeping the broad litigation fit clear.
Patent Infringement Litigation
Claims involving direct, induced, or contributory infringement under 35 U.S.C. section 271, including enforcement demands, complaints, defenses, expert issues, and litigation strategy.

Non-infringement positions, invalidity defenses, damages exposure, venue issues, discovery burden, and settlement leverage.
Pharmaceutical Patent Disputes
Patent litigation strategy for pharmaceutical and life-science disputes, including Hatch-Waxman, ANDA, biosimilar, and related patent conflicts.
Claim Construction Strategy
Claim terms, intrinsic evidence, expert testimony, and preservation issues are evaluated as trial and appeal questions.
Damages and Fee Exposure
Reasonable royalty, lost-profits theories, enhanced-damages arguments, and exceptional-case fee exposure under 35 U.S.C. section 284 and 35 U.S.C. section 285.
IP Dispute Resolution
Mediation, arbitration, licensing leverage, structured settlement, and related commercial-dispute strategy when litigation pressure creates a business opening.
Early Decisions Shape Patent Case Value
The initial response, pleadings, forum analysis, claim chart, expert roadmap, and settlement posture can set the leverage for the rest of the dispute.
What do the asserted claims cover?
Claim language, specification support, prosecution history, prior art, product documents, and technical testimony determine whether the dispute is strong, narrow, or overextended.
Which forum and timetable matter?
Venue, local patent rules, case-management orders, judge-specific practices, and related proceedings affect deadlines and settlement pressure.
What damages theory is realistic?
Reasonable royalty, lost profits, apportionment, willfulness, and fee exposure require early evidentiary discipline.
What must be preserved for appeal?
Federal Circuit review can turn on claim construction, expert exclusions, jury instructions, damages proof, injunction rulings, and preserved objections.
Representation for Patent Owners and Accused Infringers
Keyhani LLC evaluates leverage from both directions: what the patent owner can prove, how the accused party can respond, and where the dispute can resolve without weakening the client position.
Patent Owners
A patent owner needs strategy tied to the asserted claims, accused products, evidence of use, available remedies, business goal, and likely defenses.
Accused Infringers
An accused business needs a controlled first response addressing product facts, claim scope, invalidity, indemnity, customer impact, and resolution options.
Darius Keyhani
Founder and Lead Counsel Darius Keyhani has 20+ years of IP litigation experience, 80+ federal cases as lead counsel, Federal Circuit admission, U.S. Supreme Court bar admission, and an LL.M. from NYU School of Law. The Supreme Court credential is a bar-admission and appellate-practice credential, not an argument or outcome claim.
Federal Court Strategy With Appeal Preservation
Patent litigation has a specialized appellate path. The Federal Circuit has exclusive jurisdiction over many patent appeals from final district-court decisions under 28 U.S.C. section 1295.
Keyhani LLC represents clients in federal patent matters connected to New Jersey, New York Metro, Washington DC, and other forums where appearance is available. Darius Keyhani is admitted in DC, New Jersey, the Federal Circuit, the U.S. Supreme Court, SDNY, EDNY, WDNY, and D.N.J. Frances Stephenson is a Member and Principal Attorney admitted in New York only.
Claim construction, expert rulings, damages proof, injunction orders, summary judgment positions, and trial objections should be framed with potential appellate review in mind.
Choose the Patent Litigation Path That Fits the Matter
Patent owners, accused parties, and referral sources can move from the broad patent litigation parent into the narrower path that matches the dispute.
Patent Infringement
Focused infringement analysis, claim chart review, defense strategy, damages posture, or next-step litigation response.
Federal Circuit Patent Appeals
Appeal strategy for judgment, claim construction, damages, injunctions, agency decisions, and preserved trial issues.
IP Disputes and Resolution
Mediation, arbitration, licensing leverage, and related commercial resolution when open-ended litigation is not the best fit.
Can Keyhani LLC represent either side of a patent dispute?
Yes. Keyhani LLC represents patent owners enforcing rights and businesses responding to patent infringement claims, demand letters, complaints, injunction threats, damages allegations, and related settlement pressure.
When should a business contact patent litigation counsel?
Contact counsel when a demand letter, complaint, license threat, marketplace disruption, product-launch concern, competitor assertion, or indemnity issue creates patent litigation risk.
Does Keyhani LLC handle patent prosecution?
No. Keyhani LLC is a litigation boutique. The firm handles patent disputes, enforcement, defense, settlement strategy, district-court litigation, and Federal Circuit preservation, not patent prosecution.
How do Federal Circuit issues affect district-court patent litigation?
Federal Circuit issues affect claim construction, expert proof, damages, injunctions, jury instructions, summary judgment, and preserved objections.
