Assuming you know the patent #, you could Google it and see if any wire pullers come up as a result. If the patent gives a company a competitive advantage in the market, chances are they will talk about it somewhere in their literature.
You could also select likely candidates and ask if they use this patented process, whatever it is.
As the other responder indicated, if you know the patent number the best place to start is the uspto or even freepatents. The patent abstract will show the patent holder and to whom the patent was assigned (if an assignment was made). If the patent was assigned, it would usually be to a company. That company may or may not have licensed other companies to use the technology covered by the patent.
If it is steel wire please contact me offline by hitting my name/link above and i will try to assist. dependiing on what it is, I may know the former company.

Contact the patent holder. They would benefit whether they use it or if it is licensed, usually with a royalty, so they would gladly give you the information.

The hardest thing to overcome, is not knowing that you don't know.
If you know the Patent number you can enter a search and the company will probably com up. It will also help if you know the origin and Country of the Patent, or whether it was patented on-line?
If you have tried all that, you can search for "Patent Lawyers", I think they are called. They have inside knowledge of the system and that may speed things up a little.
Good luck...............And do not forget, if the patent is still current, you will have to pay for either a Licence or a percentage of the item you want to make to the Inventor.

In many cases, the USPTO would have as part of their public records the name of the entity that the patent is licensed to. Also the patent has the name of the inventor or inventors. Why not contact them. They would know who the patent is licensed to at least at inception.

I-dog, there are several choices to search in the U.S. patent literature, depending upon the data you have.
If you have a particular company and you want to see its patent portfolio, you can do an assignee search in any of Googlepatents, freepatentsonline.com, or the USPTO site. I suggest just going to the USPTO search page at http://patft.uspto.gov/. Click the Advanced Search link in the Issued Patents box. If the company's name is Wireco Inc., enter an/wireco into the Query box and search it. That will give you all patents assigned to any companies with "Wireco" in their names. If you get too many hits, narrow it - say by entering an/"wireco Inc". Or narrow it with a keyword - enter an/wireco AND spec/wire. There are many other search fields as shown on the page, and you can also search published applications the same way.
If you have a patent number, and you want to see if a certain company owns it or has licensed it, you can search the Assignment records at http://assignments.uspto.gov/assignments/q?db=pat. Enter in the patent number and hit Search. You will get the Abstact of Title to the patent - who owns it, any licensees of the patent, whether it has been used as collateral in a loan, whether it has any liens on it, everything. Just like a house - it's a piece of property.
Other than that, just do your typical Google searches with keywords, including just the patent number if you have it. Hope this helps.
