Patent strategy before filing

A good application starts with the technical core, relevant prior art and the question of which claim scope is commercially useful and legally defensible.

Prosecution and portfolio

We handle German and European procedures, deadlines, responses, divisional applications, opposition issues and commercial portfolio management.

Freedom-to-operate

Freedom-to-operate analyses help before market entry, product changes, collaborations or investment by assessing risks from third-party rights. We structure relevant rights, claim risks and options.

Enforcement and defence

In conflicts, we assess opposition, nullity, distinction, defence and settlement options in light of the business strategy.

Common questions

Before filing, before major product-development investment and before market entry, a search helps assess patentability and risk.

Freedom-to-operate assesses whether a product or process is likely to infringe third-party rights and which design-around or licensing options exist.

A utility model can be a fast supplement or alternative for certain technical inventions; suitability depends on the case.
