Fabricant

What Fabricant does

Fabricant Rubino Lambrianakos LLP, operating under the DBA "Fabricant" and "Fabricant LLP," is a privately held US intellectual property litigation boutique structured as a Limited Liability Partnership. The firm specializes in representing patent owners and innovators in high-stakes disputes against large corporate adversaries, with practice coverage spanning federal and state court patent litigation, Patent Trial and Appeal Board (PTAB) proceedings (inter partes review and post-grant review), and U.S. International Trade Commission Section 337 investigations seeking exclusion orders against infringing imports. The firm describes itself as a "pioneer in litigation funding," enabling representation of clients who might otherwise lack the capital to pursue complex IP matters.

The firm operates from four US offices — Rye (New York), Short Hills (New Jersey), Washington (DC), and Irvine (California) — placing attorneys near the major federal IP venues, the ITC, and West Coast technology clients. Headcount is reported at 11–50 employees. Lead practitioner Alfred R. Fabricant serves as managing partner, and Evan H. Langdon is identified as a partner contributing to Section 337 matters. Marketing is conducted through a corporate website and a LinkedIn profile; there is no evidence of paid acquisition, app presence, API, or proprietary technology platform.

Revenue derives from professional services fees billed to clients for IP litigation representation. Pricing is not publicly disclosed and is typically structured by matter complexity and scope. The customer base is concentrated in a single vertical: patent owners and innovators seeking to enforce IP rights. No named customer logos, no disclosed revenue, no funding rounds, and no institutional investors are present in the source data; the firm appears to operate on a partner-driven, referral-based business model with no parent company or external capital backing.
