Q: Hello, I want to ask how to contact the Centaur Nickel Pty Limited since we are considering to use one of their Patent.

A: Kudos to you for paying attention to patent issues.

1) I would work with a patent attorney to first check A) that the patent has not lapsed for failure to pay maintenance fees. (you reaching out could trigger a company to pay that fee belatedly); B) check to ensure that the claims do actually cover the product that you hope to sell (no point licensing a patent that you do not need); D) look for prior art that could invalidate this patent (you should pay less or maybe nothing to license a patent that may be invalid); D) look to see if there are other patents that would be a problem even if you did get a license to this one.

The PTO system shows the last updates to the attorney of record and the address for sending maintenance fee notifications. These will give you reasonable people to reach out to. I will defer to licensing attorneys on what should be in that initial contact.
