Understanding complex materials to draft patents

Inven2 is the Technology Transfer Office (TTO) for the University of Oslo, and Oslo University Hospital, Norway, and with whom Dehns has worked for more than 30 years.


In August 2016, Dehns Head of Biotechnology, Hanna Dzieglewska was approached by Inven2 with a highly complex invention proposal being developed by an inventor at Oslo University Hospital. The invention proposal related to methodology in the preparation of immune cells for adoptive transfer therapy, and in particular, regarding cancer treatments.

A patent application for this invention needed to be filed ahead of a conference disclosure in mid-September.


Having reviewed the invention proposal, it was clear that a highly complex invention was involved, requiring background research and a detailed discussion with the inventors, to fully understand the invention, and to place it into context, and consider all possible ramifications and applications of the underlying biological observations. Our initial claim proposals and discussions prompted the inventors further to consider the scope and possible applications of their invention, leading them to expand and develop the inventive concept. The final, iterative, drafting process involved lengthy and very technical discussions with the inventors, and analysis of their data and ideas.


The patent application was filed ahead of the conference disclosure, and is now awaiting search. Despite this work being completed in a relatively short time frame, the key issue in this case study is that the invention was incredibly technical; Dehns needed to really dig deep and assimilate very complex materials and data to understand and be able to draft a robust set of patent claims.

Thank you for this huge effort during the last few days. I have been very impressed by the way you have grasped the overall concept in such a short time and converted rudimentary feed-back into a fully developed legal text. Beautiful work under stress!
