Company patents
LEXMARK INTERNATIONAL, INC.
LEXMARK INTERNATIONAL, INC.'s patent strategy shows a surprising decline across most categories, even in its core area of Electrography (Xerography), which represents 53.0% of its portfolio but saw an 88.2% drop in patenting so far in 2026. While Pictorial / Video Communications experienced an 80.0% YoY growth in 2024, this growth was not sustained, indicating a broad shift away from new patent filings across its portfolio, with categories like Electrical Measurement and Personal Care Articles seeing significant declines or zero patents in 2026.
