Company patents
E Ink Holdings Inc.
E Ink Holdings Inc. demonstrates a shifting patent strategy, with a notable decline in its core 'Liquid Crystal & Optical Modulators' category, which still represents 36.0% of its portfolio but saw a 20.7% decrease in 2025 and a further 43.5% drop so far in 2026. Surprisingly, while 'Integrated Circuit Layout & Arrangement' has seen a dramatic decline of 85.7% in 2025 and 100.0% so far in 2026, the company is showing an emerging focus on 'Semiconductor Diodes & Transistors', which had no patents in 2023-2024 but grew to 3 in 2025 and 4 so far in 2026, indicating a potential pivot in semiconductor-related innovation.
