A) That would be a legal opinion that would be best asked - in that form - to a patent attorney.
B) To answer the underlying question, of how do I find out whether a patent is expired?
- There are several things to take into consideration - what patent term applies to the patent, whether there were extensions, whether the patent was allowed to lapse early (and isn't in a grace period), etc.
- Patent Baristas has a good article helping you step through the process.
- PatentBytes also has a good Patent 101 article introducing the steps necessary to begin determining if the patent is still in force.
- Further, the patent also may be at some point ruled invalid - which is an even more complicated topic best researched in depth, and discussed with an experienced patent attorney.
