Huisman Ringer Crane

Judge Rules Mammoet’s Intellectual Property Infringement Claim Against Huisman Is Unlawful

The Provisions Judge of the District Court of Midden Nederland, The Netherlands, has ruled that Mammoet’s Intelectual Property (IP) infringement claim against Huisman related to Huisman’s contract to provide a 3,000mt ringer crane contract to BMS is unsubstantiated and therefore unlawful.


The judge has ordered Mammoet to share the rectification which we are providing in full:

”In February 2022, Mammoet has alleged that Huisman is possibly infringing on its intellectual property rights with Huisman’s 3,000mt ringer crane contract with BMS. The suggestion of IP infringement is unsubstantiated and therefore unlawful against Huisman. The Provisions Judge of the District Court of Midden Nederland (The Netherlands) has, in a judgment of April 28, 2022, ordered Mammoet to share this rectification. On behalf of Mammoet, I hereby request you to remove any information based on the press release shared with you earlier, or alternatively, to add the contents of this letter (in full) to your article. Yours sincerely, Mammoet Holding B. V. Paul van Gelder, CEO.”

As reported, Mammoet started a patent infringement probe in early February, investigating what was described as a ”possible violation of its intellectual property rights by Huisman and BMS Heavy Cranes.”

The investigation focused on the recently announced series of land cranes, including a 3000-ton ring crane, by the Dutch crane specialist Huisman and Denmark’s BMS, Mammoet said at the time.

Huisman, in response to Mammoet’s claims, said that the company would await the outcome of Mammoet’s investigation with confidence, as well as investigate in the meantime whether the allegation was lawful.

”Huisman is the inventor of the Modular Ringer Crane. Since the delivery of the first one of its kind 25 years ago we have built up a multi-decade track record of designing and constructing this type of crane,” Huisman said in a statement back in February.

”Huisman has very high standards when it comes to intellectual property in the development of our technically advanced products. This is also the case with the design of the 3,000mt Ringer Crane for our client BMS Heavy Cranes, an entrant in the growing heavy lift market. As we do with each contract, prior to the signing with BMS Heavy Cranes, we conducted a thorough patent investigation to ensure that there were no infringements.”
