LIDDS obtains novel US product patent that significantly broadens protection on NanoZolid® pharmaceuticals

UPPSALA, SWEDEN – LIDDS AB (publ) today announces that the United States Patent and Trademark Office has approved a novel product patent on NanoZolid pharmaceutical formulations. The novel patent protects NanoZolid formulated drugs and prohibits competitors from developing corresponding products. The patent provides protection until 2037.

The US patent and Trademark Office has approved the product patent with publication number US2019/0345038A, which is a divisional patent application from original granted process patent: US 10,351,437 B2, A new method for producing calcium sulphate hemihydrate with unique properties.

The new patent protects not only pharmaceutical products obtained with the process described in the parent application, but all corresponding pharmaceutical products. This significantly broadens the patent protection as it covers also products which are not exclusively manufactured with the current LIDDS process. The product patent also significantly improves the ability to detect infringement.

– We are very satisfied to broaden the protection provided by our previous patent to cover also products made with alternative processes. This further strengthens our already solid intellectual property fundament, states LIDDS CEO Monica Wallter.
