What is a flat fee prosecution service?
Our flat fee prosecution service entails a flat service fee for the entire PCT national phase, from filing to final grant, enabling clients to enjoy cost transparency and predictability along the lifecycle of a patent application.
We take the responsibility for the entire lifecycle of your foreign patent applications:
• from filing to grant for a flat fee per country
• If desired with one patent attorney as your single point of contact
Dr. Köllner initiated the flat fee service in 2013. Since then, the service has been further developed and continuously extended. Business intelligence tools and graphical reporting have been added.
Moreover, a growing network of international patent attorneys to further roll out the service in up-to-now 60 countries has been established
Our team is our asset. We do not claim having all expertise in all segments. Whenever we have the feeling that someone else would be a better fit, we pro actively initiate the introduction.
We appreciate personal contact. Please do not hesitate to get in contact by phone, e-mail or via our contact form down below.
