Kaitsepurus successfully represented a foreign manufacturer of a generic medicinal product at Estonian courts in a patent dispute, which lasted five years and has now been settled.

Kaitsepurus drew up a statement of claim for revoking the patent of an original medicinal product and proved that the product did not meet the criteria of patentability. The disputed patent was revoked due to the lack of novelty and state of invention.

Kaitsepurus also filed another statement of claim on behalf of the same manufacturer of generic medicinal products for revoking another patent of the same patent family with the above mentioned patent. This patent dispute was also successful. The patent was canceled due to the lack of novelty and inventive step.

Kaitsepurus successfully defended in a trade mark dispute at the EUIPO a trade mark with the figure of a rooster designed for marking beer.
