We built GleanMark because USPTO.gov is stuck in 2005.
GleanMark is a U.S. trademark intelligence platform for IP attorneys and law firms. It brings search, clearance, Office Action drafting, monitoring, docketing, and TTAB research into one tool, built on 14 million USPTO records, so practitioners serve clients better, save time, and spend less on vendors. GleanMark is operated by TMZap Incorporated and was founded in 2025 by Howard Katzenberg.

From Frustration to Freedom
I spent 11 years as a CFO before founding a fintech company called Glean. When we ran into a trademark conflict over our brand name, I discovered firsthand how frustrating it is to monitor trademarks with existing tools. USPTO.gov felt stuck in 2005, and the enterprise tools I looked at ran roughly $10,000–$20,000 a year — built for large law firms, not growing companies.
After our company was acquired, I built GleanMark to solve that problem. We ingest the USPTO's daily data files the day they land, tracking status changes, assignment transfers, similar mark filings, and USPTO citations. Our goal is to give founders, brand managers, and IP professionals the trademark intelligence they need—in seconds, not hours.
