European Oppositions

Haley Guiliano, through its registered European patent attorneys working in the U.S. and in the U.K., has represented clients in European proceedings before the Opposition Division, Technical Board of Appeals, and the Enlarged Board of Appeals. We have successfully defended numerous patents involved in ongoing litigation and licensing discussions. Our U.S.-based registered European patent attorneys are locally available to provide their expertise abroad.  

How we can help:

  • Represent clients—opponents or patent owners—in oppositions in the European Patent Office and appeals to the Technical Board.
  • Coordinate opposition proceedings with clients’ worldwide patent prosecution and litigation strategies.

Communication Policy

While we are happy to have you contact us by electronic mail, telephone, surface mail or facsimile transmission, merely communicating with Haley Guiliano LLP or a Haley Guiliano LLP lawyer or employee will not create a lawyer-client relationship. Such a relationship will not arise unless and until the firm agrees with you in writing to handle a particular matter. Importantly, unless and until this has occurred, you should not convey to us any information you regard as personal or confidential, because any such information will not be treated by us as confidential or subject to any confidentiality requirements.
