Dear Lesley,
In general, you do not want an answer to the question "Do we infringe" on a public forum. For a variety of reasons.
If that is all they have, they don't have a US patent. You can go to USPTO.gov and look up that publication number. The application is pending and no patent has issued. Until the patent issues, an actionable claim does not exist. They may have a patent in the Netherlands.
Good luck,
Todd
