Company patents
TetraMem Inc.
TetraMem Inc. demonstrates a strong and rapidly accelerating focus on core semiconductor memory technologies, with Memory & Storage (Static) and Memory Devices (Structural) collectively representing 90% of its portfolio and experiencing significant growth in 2025 (YoY +257.1% and +214.3% respectively). Surprisingly, despite its core business, the company appears to be shifting away from foundational Integrated Circuit Layout & Arrangement, which saw a -100.0% decline in 2025, and Specialty Semiconductor Devices (Legacy), also down -100.0% in 2025, indicating a highly specialized and forward-looking patent strategy rather than broad semiconductor coverage.
