Does this mean patent is expired and I can manufacture the apparatus? can former patent owner renew it and how would it affect my production?

2014-04-08 Anticipated expiration 2019-10-31 Application status is Expired - Fee Related

Is this patent valid worldwide or it has to apply for each and every country?



  • It would be best if you please provide the patent number. However if the anticipated expiration would have been 2019-10-31, then it would have expired by now (this actual day in fact) even if the fees were up to date. – Eric Shain Oct 31 at 23:17
  • We really need more info to be very helpful - and yes patents are territorial and only valid in the location they are granted. – George White Nov 1 at 0:21
