Steakholder Foods’ 3D-printing patent for plant-based fish wins global validation

Steakholder Foods has received a positive Written Opinion from the International Searching Authority (ISA) for its international patent application (PCT/US 24/34252), which covers the printing system of its HD144 printer designed for plant-based fish.

The ISA confirmed that all 21 claims in the application meet the criteria of novelty, inventive step and industrial applicability. The patent covers a multi-component architecture that manages bio-ink materials, gas pressure control and a central processing module that coordinates the printer’s functions.

The HD144 printer uses Steakholder’s proprietary DLS (Drop Location in Space) drop-on-demand technology, which allows for precise deposition of plant-based micro-droplets. This enables realistic structuring and marbling of plant-based fish to mimic the texture and appearance of conventional seafood.

The decision strengthens Steakholder’s position as it moves toward national phase filings and global commercialisation.

“This positive opinion from the ISA is a meaningful milestone that reinforces the strength of our IP and the disruptive nature of our technology,” said Arik Kaufman, CEO of Steakholder Foods. “Our DLS-based HD144 printer is raising the bar in plant-based seafood production, and this patent supports our global commercialisation and strategic partnership goals.”
