Can I Refile an Expired Patent?

Posted by Michael Shimokaji | Jul 11, 2014 | 0 Comments

Question: If my patent expires, can someone else re-file the exact same and claim it?

Question Detail: If yes, what happens to my current product that was governed by the patent that expired? Can I reclaim the patent?

 Answer: Someone else may file a patent application on the same product and receive a patent, but that does not mean the patent is valid. Once your issued patent expires, it cannot be validly re-filed.
