The Beijing Intellectual Property Court upheld dsm-firmenich’s patent rights, marking its second victory against challenges from Haineng.
The Beijing Intellectual Property Court recently upheld the China National Intellectual Property Administration’s (CNIPA) decision to maintain dsm-firmenich’s patent on swine compound premixes containing 25‑hydroxyvitamin D3.
This ruling follows an earlier invalidation challenge by Shandong Haineng Bioengineering Co Ltd, which also failed. The latest judgment confirms dsm-firmenich’s continued ability to protect its innovation in animal nutrition.
With this ruling, dsm-firmenich has now defended its patent against two separate invalidation attempts brought by Haineng. The company emphasized that these outcomes highlight the strength of its intellectual property portfolio.
By securing repeated recognition from both CNIPA and the courts, dsm-firmenich reinforces its position as a technology leader in vitamin D3 applications for animal feed.
dsm-firmenich is a pioneer in 25‑hydroxyvitamin D3, the major circulating form of vitamin D. Marketed under the Hy‑D brand, the compound is widely used in animal feed formulations. Its role in supporting livestock health and productivity underscores the importance of patent protection for the company’s innovations.
The brand’s global presence reflects dsm-firmenich’s leadership in animal nutrition solutions.
Fidelis Fru, Head of Business Development for Animal Nutrition & Health atdDsm-firmenich, welcomed the judgment. He noted that the company’s comprehensive patent portfolio protects ongoing investments in research and innovation.
Mr Fru added that dsm-firmenich proactively monitors third‑party activities to prevent infringement and acts when necessary to safeguard its technology. This vigilance ensures customers continue receiving high‑quality products and services.
Beyond animal nutrition, dsm-firmenich manufactures and combines nutrients, flavors, and fragrances, offering solutions built on science and renewable ingredients.
The Swiss‑based company operates in nearly 60 countries and employs close to 30,000 people worldwide. Its success in defending patents in China strengthens its global reputation as an innovator in nutrition, health, and beauty.
