Analysis · CTKB · Industrial Applications And Services
A Delaware jury found Cytek infringed one Beckman Coulter patent claim under the doctrine of equivalents, awarding $56.11 million in damages — $20 million in lost profits plus $36.11 million in royalties. That's a material hit for a company with a $625 million market cap and a widening net loss of $12.2 million last quarter. Cytek won on three of four claims, so its core Full Spectrum Profiling products remain on the market, but the damages award alone exceeds a full quarter of revenue. The company plans post-verdict motions and a possible Federal Circuit appeal, which could take years and add legal costs. The verdict does not force product changes, but the financial exposure and ongoing litigation overhang are significant.
