The Oslo County Court concluded just before Chrismas 2020 that BioMar's smoltification feed IntroTuning does not infringe STIM's new European patent, which was granted in the summer of 2020, and therefore rejected STIM's demand that a ban should be placed on the sale of Intro Tuning. STIM appealed this decision to the Borgarting Court of Appeal who reconsidered the case and came to the decision on April 12, 2021 as the Oslo City Sheriff's Office. The production and sales of BioMar’s Intro Tuning remain unaffected. 

“Even though the outcome of the appeal was as expected, we are very happy that the Court of Appeal has now confirmed that the County Court decision was correct. This means that fish farmers can still choose feed from BioMar's product portfolio that promotes growth and health during smoltification and transfer to seawater,” said Håvard Jørgensen, managing director of BioMar Norway.
