Feinberg Day

What Feinberg Day does

Feinberg Day is identified in firmographics as a Burlingame, California-based law firm founded in 2011 that offers general litigation, intellectual property litigation, and International Trade Commission (ITC) services, with a headcount of 11-50 employees. Substantive source content, however, centers on a patent-litigation-focused entity operating under the Alberti Lim brand (Alberti Lim & Tonkovich LLP, dba Alberti Lim), whose website infrastructure incorporates a "feinberg-day" theme, suggesting a branding or predecessor relationship between the two. The underlying firm is structured as a California limited liability partnership, headquartered in the Silicon Valley/Bay Area (650 area code), and represents patent owners rather than accused infringers.

The firm is described as having a team of over 20 cross-functional and specialized IP litigation experts covering electronics and computer science, medical devices, and life sciences, with dedicated International Trade Commission (Section 337) practice. Capabilities span U.S. district court patent litigation and ITC proceedings, targeting high-stakes patent enforcement and defense matters. No software products, applications, APIs, or proprietary technology platforms were identified in the input; the offering is professional services in nature.

The business model is fee-for-service legal representation in patent litigation matters, with revenue derived from professional legal fees. Pricing is quote-based and not publicly disclosed, with engagement structures typically taking the form of hourly rates, contingency arrangements on certain cases, or flat fees depending on matter complexity. Go-to-market is sales-led and direct, conducted through enterprise-level engagement with patent-owning companies and institutions, supported by analyst-ranking-driven earned media (Chambers and Partners, IAM Patent 1000, Patexia, U.S. News Best Lawyers). The firm operates across the U.S. with no disclosed international office footprint and no external private equity or venture capital backing.
