Keyhani LLC IP Litigation Boutique
Keyhani LLC is a Washington, DC-based intellectual property litigation boutique for clients facing patent, trademark, copyright, trade secret, NDA, related commercial, and appellate disputes.
A Firm Built Around Litigation, Not General Legal Services
Keyhani LLC represents clients when an intellectual property dispute requires enforcement, defense, federal-court strategy, settlement posture, or appeal preservation. The work is tied to patents, trademarks, copyrights, trade secrets, NDA breaches, and related commercial conflicts.
Litigation-only focus keeps the engagement clear.
Keyhani LLC focuses on litigation and dispute strategy. Non-litigation IP rights procurement and standalone administrative proceedings are separate from the firm's litigation role. PTAB, ITC, IPR, PGR, and TTAB issues may matter when they affect federal litigation, settlement posture, estoppel, stays, or appeals.

The firm serves clients from Washington, DC, with core relevance to DC, New Jersey, New York Metro, Northern Virginia, and Federal Circuit appellate work. Court-specific engagement depends on forum, admissions, local-counsel needs, and case posture.
