Mr. Duckeck, what is your role as Director Intellectual Property at the company?
Together with my seven employees, we handle all tasks related to patents, designs, and trademark protection. This includes pursuing patent infringements. I make sure that counterfeit ebm-papst products are taken off the market and don’t damage our good name.
How does this work exactly?
We work on this with an agency called CorSearch, whose software – which also uses artificial intelligence – scours the internet for offers of ebm-papst products. The adaptive software recognizes counterfeits, which then end up on a list. We look at this list and decide which advertisements need to be deleted.
Is that how it always works?

No, sometimes we are also approached by customers who are familiar with the quality of our products but are suddenly experiencing problems. An example of this was when a customer contacted us to complain that the fans they had installed were too loud.
We found out that the supplier had unknowingly purchased counterfeit ebm-papst products on the internet because we had a supply bottleneck at the time. Actually, despite all the frustration, we took it as a compliment, as the customer was used to a higher level of quality from our products.
How many counterfeits do you pursue on a routine basis?
In collaboration with CorSearch, we reviewed around 70,000 online ads in 2021. Of these, CorSearch reported 60,000 to us as potential fakes, and 42,080 were removed.
Are there sometimes false alarms?
That’s quite a rare occurrence, but it does happen. We once had a case where a trainee placed pictures of counterfeit goods in an offer on the internet. However, when we checked, we found that the trader was authorized and that the issue with the pictures was just an oversight.
Update: ebm‑papst uncovers Chinese counterfeiting network
ebm‑papst, leading manufacturer of fans and motors headquartered in Mulfingen, Germany, is once again demonstrating its tireless commitment to protecting its customers and safeguarding its brand reputation. In September 2024, investigators uncovered a Chinese factory selling counterfeit ebm‑papst products. About a year ago, the company successfully raided a counterfeiting factory. Every year, counterfeiting and the associated investigations cause several hundred thousand euros in economic damage and total costs for ebm‑papst.
At the beginning of July 2024, ebm‑papst again received a report from a long-standing customer who had received products from the company that were of low quality compared to previous purchases. Ralf Duckeck, Vice President Intellectual Property of the ebm‑papst Group, and his international team responded immediately to this suspicion of product counterfeiting and tried to find out further details.

“Counterfeit products pose a significant threat to the integrity of our brand and the safety of our customers. Counterfeit products may contain inferior materials and may not meet the strict quality and safety standards that we guarantee for our original products. We are therefore committed to fighting counterfeiting and protecting our customers,” explains Duckeck.
Despite several hurdles, such as false addresses, extensive investigations led the team to a suspected counterfeiting workshop in Foshan that was pretending to be an ebm‑papst branch. The suspicion against this workshop was confirmed after counterfeit ebm‑papst labels were found in the waste. Further investigation revealed that the operator of this counterfeiting workshop was already responsible for the factory closed by ebm‑papst in 2023 and had now relocated and significantly expanded his company premises. The operator in question was able to evade the Chinese authorities in 2023, but was already known to the police, having been caught engaging in similar activities in 2016.
Combating counterfeiting is a top priority for protecting our brand reputation.

Based on the investigation results and the resulting burden of proof, the Foshan Public Security Bureau (PSB) was informed. In September, the PSB decided to carry out an unannounced raid together with the ebm‑papst team. The raid was successful, and those responsible for the counterfeiting operation were arrested.
The activities of the counterfeiting operation in Foshan included the purchase of used, original ebm‑papst fans from overseas, which were reconditioned and then relabeled. The reconditioned fans were sold as new, original products. A total of four people were arrested in the raid, including the operator of the counterfeiting operation and his wife. With this arrest, ebm‑papst was able to take down a professional counterfeiting network. In addition, 301 fans and 500 ebm‑papst labels were seized during the raid. Investigators were also able to secure products and labels from manufacturers in similar industries.
The case has since been handed over to the public prosecutor’s office in China. It can be assumed that he will receive a prison sentence as well as a fine.
“Combating counterfeiting is a top priority for protecting our brand reputation. Our customers rely on the quality and reliability of ebm‑papst products, and it is our aim to maintain this trust. The successful investigations underline our commitment to protecting our customers from inferior imitations. Our goal is to ensure that they always receive the quality and performance they expect from ebm‑papst – no compromises, no counterfeits,” emphasizes Dr. Klaus Geissdoerfer, CEO of the ebm‑papst Group.
