Egg carton manufacturer Brødrene Hartmann has filed a lawsuit against Omnipac at the UPC, shortly before Easter. The Danish company accuses its German competitor of infringing a patent on a new type of sealing technology for egg cartons. But this is not the first time that the two opponents have faced each other in court.

Brødrene Hartmann has accused competitor Omnipac of infringing European patent EP 2 755 901, which protects a display and distribution package for eggs. JUVE Patent has learnt from a well-informed source that the claimant filed a lawsuit with the UPC’s Düsseldorf local division on 18 March.
Over the years, egg packaging has evolved from a simple means of carrying the goods to packs with form-fitting shapes. While such cartons provide plenty of space for labels, they also protect the eggs from damage. EP 901 protects a technique to conceal the closure of the packaging, allowing for larger labels on the front.
Modern egg packaging is the focus of the dispute.
In 2019, the patent already survived an opposition at the European Patent Office. None of Brødrene Hartmann’s competitors have yet filed a revocation action against the patent at the UPC.
Brødrene Hartmann is seeking an injunction from Omnipac in Germany, France and the Netherlands, the three countries in which EP 901 is valid.
The packaging market is highly competitive. Brødrene Hartmann and Omnipac, alongside Finland-based company Huhtamaki, dominate the egg packaging market in Europe.
Billions of eggs are sold in Europe each year. In Germany alone, 20 billion eggs were sold last year. The number of egg cartons is therefore also likely to be in the billions.
In 2014, Brødrene Hartmann sued Omnipac for infringing one of its patents, EP 1 373 100 B1. Meanwhile, the Düsseldorf Regional Court stayed the infringement proceedings until there was a final ruling in the nullity case. After the German Federal Court of Justice upheld EP 100, the two companies settled the dispute with an agreement.
Later, Brødrene Hartmann also sued Huhtamaki in Germany for infringing its patent. However, the two competitors also settled the dispute relatively quickly.
Düsseldorf-based Heuking partner Anton Horn is once again acting for Brødrene Hartmann, having already led proceedings for the Danish company against Omnipac between 2014 and 2019. At that time, German patent attorneys from Cohausz & Florack assisted the Heuking team, as did the company’s regular Danish advisors from Budde Schou.

However, the UPC also has an impact on how companies select their counsel. On the side of Brødrene Hartmann, German patent attorneys are no longer involved in the UPC proceedings. Only the Danish patent attorneys at Budde Schou are providing technical support.
JUVE Patent is not aware of which law firms Omnipac relies in the UPC dispute. In the 2019 case in Germany, lawyers and patent attorneys from the Hamburg-based IP firm Glawe Delfs Moll represented the client.
