Patent Searching

Tips for locating company patents

  • The owner of the patent, an individual or entity, will be listed in the assignee or applicant field.
  • Companies or employers are not always the assignees.  Rights can be held by third parties
  • University patents can be filed under their governing board, i.e.  Board of Regents
  • Company names are not uniform, so search for all variations
  • Examine the patent’s abstract, specifications, and claims for information about the invention
