The mere fact that the word "linux" appears in a patent is meaningless as long 1) you are not infringing any of the specific use of linux as stated in the claims of the 25 issued patents, or 2) the patent holder doesn't assert their patent rights against you; or 2a) a court does not find you are infringing any valid claim; or 2b) the patent office doesn't throw out the patent on prior art or technicality; or 2c) you
and so on ....; or 3) you have a valid patent use license from the patent holder.
See, I agree with you.
