Patent Office Proceedings: Prosecution & Oppositions

The grant procedure allows the applicant of a patent to influence its scope of protection. This is done by adapting the claims in view of the prior art cited by the patent office. Often, a choice must be made between different embodiments. Remaining embodiments can be branched off into divisional applications. The grant procedure is a chance to ensure a strong patent.

Thanks to our extensive experience with large patent portfolios, we can minimise your workload as an applicant. We conduct grant procedures before the German Patent Office (DPMA) and the EPO as well as international PCT grant procedures. For grant procedures abroad, we cooperate with local law firms, which we select specifically regarding the technology to be patented.

An opposition is a cost-effective way to get rid of a patent that constrains ones freedom to operate. A patent owner who receives an opposition has another chance to ensure a strong patent.

In opposition proceedings, the procedural rules of the patent offices must be considered. These make it difficult for an opponent to extend the attacks at a later stage (e.g. by newly searched prior art). For the patent owner, they make it difficult to change the version with which he wants to defend the patent. Experience and foresight are crucial in this situation. Our practice from court litigation helps here.
