U. S. patents

You can obtain information about finding and using patents by consulting one of the college librarians for engineering or science.

If the patent you need is a U. S. patent that is for some reason not included in the USPTO database, or if it is a foreign patent, then we may be able to obtain the patent for you through interlibrary loan at no cost to you.

  • esp@cenet is a gateway to patent indexes, with support for several languages when accessed through the national offices of member states
  • English, German, and French interfaces are available on the European Patent Office's Patent Databases page.
