Kjell Inge Rokke-owned Aker BioMarine has appealed a recent court ruling that found the group did not gain ownership of a krill processing patent when it acquired the vessel Juvel from bankrupt competitor Emerald Fisheries.

Stig Remoy, the owner of Emerald and krill competitor Rimfrost, won the case, allowing his company to retain the patent.

Aker claimed it owned the patents, had rights to use them, and additionally sought compensation as part of a previous dispute with Norwegian bank Nordea and government-backed Innovation Norway.

Juvel krill meal is reportedly worth five to 10 times as much in the market than the formula produced on Aker’s trawlers with its herring oil factory technology.

Remoy told Norwegian newspaper Sunnmorsposten that he was not surprised by the appeal.

"Aker has lost or pulled the last six cases against Rimfrost in Norway and the US," he told the paper. "That should make them think."

Aker was forced to pay NOK 2.3 million (€235,823/$271,614) in legal costs as a result of the ruling.
