Bayer CropScience and Bion Tech of Taiwan, Republic of China, a producer of biological crop protection agents, have settled a patent infringement case in Korea. No financial details of the settlement were given.

Under the terms, the Bayer sub-group has awarded Bion Tech a royalty-bearing license to sell lipopeptide-containing products based on Bion Tech's proprietary Bacillus subtilis Y1336 strain. This covers various unspecified countries and has a focus on Asia.

Bayer said the Taiwan company's strain Y1336 produces agrastatin, which is covered by claims related to lipopeptides in its patent portfolio and "contribute to the unique properties" of its Serenade brand products.
