Surgeons need to stop bleeding and seal tissue quickly during operations on organs such as the liver. GATT Technologies, a Dutch company, developed GATT-Patch, a sealing patch that the EIC award described as "one patch stops all" surgical bleeding and organ leakage. In October 2021 the EIC selected its project to scale up production of the patch.
No GATT-OPSA grant project appears in the EU's CORDIS database. In a November 2023 release, Johnson & Johnson said: "In May 2022, Ethicon acquired GATT Technologies B.V., a Netherlands-based company". By 1 January 2023 GATT Technologies B.V. was listed as a subsidiary of Johnson & Johnson in the US group's annual report, and its website now redirects to Johnson & Johnson MedTech. The price has not been published.

Where GATT Technologies Stands Today
GATT Technologies B.V. appears in Johnson & Johnson's list of subsidiaries as of 1 January 2023 and in every annual report since, most recently the 2026 filing. The company's domain, gatt-tech.com, forwards to a J&J MedTech page. The patch itself is now sold by Ethicon as ETHIZIA: J&J announced its CE mark in November 2023, with an EMEA launch expected in the first quarter of 2024, and said that in 80% of clinical trial patients it "stopped bleeding in 30 seconds, an average of six times faster than the leading Fibrin Sealant Patch". Neither J&J's filings nor the sources we could access give the price or timing of the deal.
The Product: A Patch Against Bleeding
GATT-Patch is applied to bleeding or leaking tissue during surgery. On ClinicalTrials.gov, GATT sponsored three completed trials: a 56-patient study in open liver surgery from April 2021, a 132-patient comparison with the sealant TachoSil in liver surgery from August 2022, and a 53-patient comparison with Surgicel in minimally invasive liver and gallbladder surgery from October 2023, both after it had joined J&J.

GATT-OPSA award description, EICWhat the EIC Project Promised, and What the Record Shows
The award was for scaling up production of GATT-Patch, as blended finance. We searched the CORDIS Horizon Europe data and found no project with GATT Technologies as coordinator. EIC Accelerator grants go to small and medium-sized enterprises, and GATT became part of Johnson & Johnson soon after the award; whether a grant agreement was ever signed is not public.

What Has Happened Since the Award
The Money
We found no EIC Fund investment, no disclosed acquisition price and no record of EIC grant payments. GATT's earlier investors and funding were not accessible for this article.
What cannot be checked
What J&J paid for GATT, whether any EIC money was paid, and ETHIZIA's sales are not public in the sources we used.
Why Europe Should Care
An EIC selection is meant to help a European start-up scale. Here the start-up was bought by a US healthcare group, which is a commercial success for its founders and investors. For the EU, the award leaves no public trace, and the product's European future is in J&J's hands.
What the project promised
Scaled-up production of a patch that stops surgical bleeding and organ leaks.
What the record shows
Three completed trials and an acquisition by Johnson & Johnson; no EIC project on record.
The Verdict
Selected, then sold
GATT Technologies' technology was good enough for Johnson & Johnson to buy it within about a year of the EIC selection. That validates the choice. But the EIC award itself has no public record, and nothing shows whether EU money played any part.
GATT Technologies and Johnson & Johnson have not been asked for comment for this article. It is based entirely on SEC filings, EU data and the trial registry, linked throughout.
