In reference to the patent: US5488743

Good morning,

I hope all is well. I was looking through this patent and I see that the maintenance fees have lapsed. Does this mean the patent is not in effect and in forced? Also, if my design differs from this design, what legal actions should I take so we do not interfer with this patent? Thank you for your help and I look forward to hearing from you soon.

Sincerely,

Joseph Lavinder Lunos Inc.

Lapsed patents are no longer enforceable. You would need to take no legal actions unless you have invented an improvement on the lapsed patent that you wish to prosecute.

You would need to do your own research and patent searches.

Not intended as legal advise please seek your own counsel.
