Connecting the world of commerce with science, creativity and designs – the protection of your intellectual property is the basis for a sustainable and successful future. We invite you to contact us with your questions or needs in intellectual property matters.
It is our mission and passion to provide our clients with a thorough and practical understanding of their IP situation, which allows for cost-effective and long-term strategic decisions.

We offer an outsourced in-house IP counsel, meaning that upon demand, we serve and advise our clients on-site as an in house IP department would. Our on-site services include in-house training for technical, management and marketing staff members and IP-strategic consulting.

Our cost-efficiency is reflected by detailed and transparent debit notes. Our clients will be informed on estimated costs ahead as well as on the exact amount of any costs of external services.

Kasche IP Partner specializes in all aspects of intellectual property rights, including patents, trademarks and industrial designs.
Our practice provides professional IP services to clients which include Start-Up Companies, Corporations, Research Institutes, Technology Transfer Offices and individual inventors.

We offer a commercially-aware and personalized approach, tailoring our counsel to our clients’ needs.
