Hands-on, with a personal approach

Clients often tell us that we’re approachable. We love hearing this, as we’ve set up our organization to be hands-on and personal. The patent attorney handling a case always liaises with the client personally, and preferably also with the inventor(s), so as to ensure that all relevant information is documented. Our formalities officers, who are responsible for administrative and litigation support, also liaise directly with the client.

We will inform you in advance of the steps to be taken in the proceedings, and what the eventual cost will be.

Our commitment to providing high-quality services is evidenced by our ISO 9001 (Quality Assurance) and ISO 27001 (Data Protection) certifications.
