Intellectual Property (Litigation/Enforcement)

Intellectual Property (Litigation/Enforcement)

In IP infringement litigation in general and in patent infringement litigation in particular, it is common practice for the defense of invalidity of patent to be submitted and for the defendant to initiate nullification proceedings at the Japan Patent Office at the same time, with the related appeal proceedings held at the IP High Court.  Therefore, a team of specialists who have expertise in not only civil proceedings at the court but also nullification proceedings at the Japan Patent Office and the IP High Court becomes necessary.  Sonderhoff & Einsel has outstanding teams for IP court proceedings consisting of both patent attorneys and attorneys-at-law. We fully leverage the wealth of experience our patent attorneys have in their technical fields and in the IP prosecution process, and the outstanding expertise of attorneys-at-law in IP infringement litigation as well as nullification proceedings.
