I thought the rule of thumb for keeping records was life of the patent plus
7 years,
because a patent infringement action may be brought up to 6 years after the
patent expires
(so I guess you could calendar the exact date 6 years later).  I suppose
someone
might discover infringement even after that and bring suit but it seems
very unlikely.
Google says fraud or concealment of infringement does not extend the
statute of limitations....??
