- My understanding is that RSA has patented "all implementations"
- of a public key algorithm. (You can't patent an algorithm,
- but at some point some patent lawyer figured out you can
- patent the implementations.)
-
- The RSA system that is licensed is only a subset of all
- conceivable instantiations of the algorithm. Unless RSA
- licenses all of these under reasonable conditions, there
- may be some merit to the "sitting on the technology" criticism.
-
- So for example, if I wanted to hack out a non-conforming
- implemenation of an RSA-type encrypter, for small-scale
- use, I would probably in RSA's opinion be in infringement. Would
- they sell me a license at reasonable cost and hassle?
- (Defined as less cost and hassle than it took to write the
- code in the first place...)
