Without compromising the appropriate protection, we give your idea a clear direction.

Since 1967, the name Ostriga has stood for sound advice in the field of intellectual property. We provide companies with reliable advice on patent, trademark and design law. We offer expertise in all technical fields – nationally and internationally – and develop tailor-made solutions for your needs.

The subject matter is complex, the learning curve steep but we take the time to answer your questions in a relaxed atmosphere. In this way we become a team, making your company goal our concern.

Sound legal advice has its price. All the more annoying are intransparent or incomplete cost details. Our calculations are complete, without hidden fees. Regarding unknown eventualities our estimates are rather generous. All this to make our cost estimates fair.
