Can anyone enlighten me as to the "real deal" on Altivec (or otherwise) enhanced codes and patents related to them? I was recently pointed to an enhanced version of Bill Pearson's FASTA tools, which turned out to have been de-enhanced at the request of lawyers from a company called Sencel. Sencel appears to have patented a vectorized implementation of Smith-Waterman, and is (seemingly) using that patent aggressively. I was disappointed to note that they do not offer any products that actually make use of the Altivec technology (at present). Note: I'm waiting on a response from Sencel as to their point of view. In general though: Is this the sort of thing we're going to see more of? -Chris Dwan University of Minnesota
