Vulcan was an innovator in pile driving equipment for more than a century. This history can be documented in part by the patents that were issued to Vulcan's people, in addition to those which it acquired externally. We also include patents that were related to Vulcan either because they were issued to a Warrington or they related to a Vulcan product but were never formally assigned to the company. If you see that a patent is missing or incorrect, contact us.

We also have experience in acting as an expert witness in patent disputes; contact us if you are interested.
