This is Jim from New York-I hold a design patent since 2002 and have found possible infringers.I have notified them politley telling them they are infringing.One of the infringers has told me he has been selling my patent product since 1998 therefore he is not infringing.he said he has a catologe dated 1998 that shows he was selling it back then,therefore he can and will continue to manufature,sell and distribute it.because he was doing so before i got the patent.Is this True ? can he continue to do so? also can he distribute it to others and can they sell them or are they infringing.thanks in advance....Jim
