Yes, the first and original magnetic clip patent is expired....in 1987 i think!

Wonderful Optical in Taiwan (Mr. David Chow) applied another patent with improvement in 1998 and sold the patent right to a Canadian company and now both of them sue people for living.:shiner:

But if the patent was expired how could they "sue people for living?"

According to Mr. David Chow, his current "invention" would cover the first expired patent plus "new improvement". He sold his patent right to a Canadian company who loves to sue anyone offers frames with "magnetic clips" for any reason. :hammer:
