Chinese and US patent authorities issue notices of allowance for patent for key component in cold spray ColdZyme

According to notices from patent authorities in China respectively USA, Enzymatica will be granted patents for the cod enzyme that is a key component for Enzymatica’s cold spray ColdZyme®. The patents will be valid in each country until 2036.

The Chinese and US patent authorities have both issued notices of allowance for a patent for the cod enzyme that is a key component for Enzymatica’s cold spray ColdZyme®. The expected patents will be valid until 2036 in China and the USA respectively. The final grant in each country is expected during the autumn 2021 after finalization of the application process. The patents derive from the global patent application that was filed in 2015 and was granted for Europe in May 2020.

“The patents in China and the USA give ColdZyme® and other products based on the same technology platform a strong position in both markets. The two granted patents are important notices for Enzymatica’s continued international expansion”, said Claus Egstrand, Chief Operating Officer and incoming (January 2022) CEO at Enzymatica.
