Experience

Specialising in the field of chemistry, particularly medical devices, fibres, fabrics, personal care and cosmetics, Inge has over 20 years of experience in the patent profession both in-house and in private practice. She deals with all IP related topics, in particular drafting and prosecuting patent applications, EPO opposition and appeal proceedings, opinions on freedom-to-operate and validity as well as IP strategy and portfolio management.

Inge has extensive experience dealing with freedom-to-operate, infringement and validity opinions which she partly obtained during the 11 years she worked in-house for a leading specialty chemical company in Germany. She has a broad range of expertise handling oppositions and appeals at the EPO as well as drafting and prosecuting patent applications worldwide.

In addition, she has managed global patent portfolios both in private practice and in-house providing strategic advice to patent professionals, marketing and application technology leaders. She also advises on the German law for employee’s inventions.

Inge graduated at RWTH Aachen University in Germany and obtained a PhD in Chemistry at the DWI Aachen while working on projects for the German Federation of Industrial Research Associations (AIF).

After two years of running the search department of a leading personal healthcare company, Inge joined a specialty chemical company where she qualified as a European Patent Attorney. She moved to Scotland in 2012 to work in private practice, before joining the Edinburgh office of HGF in January 2016.
