Tanja Preissner
Senior Associate

Tanja works within the Life Sciences group covering a wide range of technical areas within biotechnology. Her clients range from large multinationals to UK start-ups, and she is closely involved with shaping many of her clients’ IP strategies, including those for key commercial products. She also manages large global patent portfolios with extensive experience in the prosecution of cases across the globe, as well as in the defence of granted patents. Tanja has also successfully attacked granted European patents in opposition proceedings, and has experience in providing validity opinions as well as freedom to operate analyses.

Tanja joined Carpmaels & Ransford in 2007 after graduating with a Biology degree from Ludwig-Maximilian University in Munich, where she focused on genetics, molecular biology and cell biology. Her final year project at Cancer Research UK London concerned the molecular organisation of the MRC complex in cancer cells, and was supported by a scholarship from the DAAD.

For her PhD, Tanja moved to Imperial College London where she studied the epigenetic changes underlying gene silencing in early embryonic development. This involved biochemical studies of protein complexes in mouse embryonic stem cells. For this work, she received a prestigious pre-doc fellowship from the Medical Research Council.
