One thing here doesn't make much sense - the compression algorithm technically is a mathematical algorithm. Mathematical algorithms cannot be patented. So why is the patent on something that cannot be patented an impediment in this issue? That said, I'm sure there are ways to confuse the algorithm part by throwing some mentions of physical servers or what not into the patent application...
