Who we work with

It is hard to beat the industry standard when you are the industry standard. (Although we do try.) That’s why you will find our software in all the major chemical companies and educational institutions worldwide.



At Bayer, we started using Chemaxon's Markush Editor for drafting claims of patent applications several years ago. The Markush Editor is a very user-friendly approach for a better understanding of the chemical field to be patented and offers the patentee a new way of analyzing the chemical environment.
