As hard as the rsa website :-), the FAQ reads <quote> Question 6.3.1. Is RSA patented? RSA is patented under U.S. Patent 4,405,829, issued September 29, 1983 and held by RSA Data Security, Inc.; the patent expires 17 years after issue, in the year 2000. RSA Data Security has a standard, royalty-based licensing policy, which can be modified for special circumstances. The U.S. government can use RSA without a license because it was invented at MIT with partial government funding. In the U.S., a license is needed to "make, use or sell" RSA. However, RSA Data Security usually allows free non-commercial use of RSA, with written permission, for academic or university research purposes. </quote>
