If it does, it would be grounds to render the patent invalid. The lawyer may need to know those things. The situation is the same whether you are distributing just Linux or a whole Linux-based GNU system. I don't think you need to worry about getting a license for this particular patent, though. Someting to keep in mind when looking at them is the claims.
Claims are really the major part of a patent that have any relevance.
However all the companies that are using 'pivit logic' with databases are at risk of possible infringement. Now even if you have proof of this logic in the linux kernel one must prove that it is obvious to use such logic within a database. Personally I am amazed at what people today call novel and want patent protection over. So next patent you see read the claims carefully first and look for the independant claims as they are the 'meat'. Elsewhere, Gregory McLean suggested pointing out to the US Patent Office that Linux represents prior art, and getting the patent anulled on that basis.
