Q: How do i contact the holder of this patent?

A: Step 1 -- make sure that you are looking at an issued patent not a published application (Justia did not pass along whatever you are looking at).

Step 2 -- make sure that the patent has not expired, lapsed, or been invalidated.

Step 3-- be sure that you need the patent. Do you plan to do something that have every noun, every verb, and every relationship in at least one of the independent claims (the claims that start from scratch rather than adding something to another claim). See https://www.flynniplaw.com/services/legal-services/freedom-to-operate/opinions

Step 4--If you plans currently would infringe at least one independent claim that is still in force, can you tweak your design so that you do not need the patent? Would that leave you with a commercially viable product?

These questions often require consulting a patent attorney but I like to give people a framework so that they understand the process.

A: If you really want to contact the owner, then you can use the USPTO assignment records to see who is the current registered owner. https://assignment.uspto.gov/patent/index.html#/patent/search

Sometimes a patent is sold and the records are not updated but the last owner should be able to let you know who is the current owner. If the patent was never assigned, then the owners started out as the inventors and you can start by finding the inventors. Mailing addresses for the inventors should be in the file history available at USPTO Public PAIR.
