Patent Sight and
entrepreneurial acitivities of Professor Dr. Holger Ernst.

The TIM chair has a very strong entrepreneurial orientation. We encourage and support entrepreneurs. Prof. Ernst has supervised many business plans written by WHU students and he has served on the advisory board of start-up firms and he provides support to start-ups as a business angel and/or advisor. Prof. Ernst has been a successful entrepreneur himself (see below). If you have a great idea and need our help and/or support, do not hesitate to contact us at holger.ernst(at)

Prof. Ernst co-founded PatentSight, located in Bonn, Germany, that specializes in the development and selling of software products and consulting services in the field of business intelligence based on patent data. PatentSight is a market leader in its field and serves well-known clients worldwide. PatentSight was acquired by RELX (Lexis Nexis) in 2018.

PatentSight’s unique products are based on Prof. Ernst’s long-term and groundbreaking research on patent analytics, patent valuation and patent management. His first key work is his PhD dissertation published in 1996 (Patentinformationen für die strategische Planung von Forschung und Entwicklung, DUV-Verlag, Wiesbaden. (received two best dissertation awards from “Unternehmensverband Schleswig-Holstein” and from “Stiftung Industrieforschung”)). Based on this and many other publications, Prof. Ernst became a thought leader, invited speaker and successful consultant in the field of patent analytics and patent valuation worldwide. He developed and implemented new applications and indicators for patent analytics and especially new metrics to assess the quality of patents since this is the fundamental prerequisite for reliable and meaningful patent-based analytics. Another key publication about applications of patent analytics and a new method to assess the quality of patents was made in 2003 (Patent Information for Strategic Technology Management, in: World Patent Information, Vol. 25, Issue 3, pp. 233-242). This paper had a huge impact in the field as indicated by very high citation rates (# 1 cited paper in WPI).

As early as in 1996, Prof. Ernst established a consulting business in which he conducted many patent analytics projects based on a self-developed proprietary software solution with many blue chip firms across multiple industries, mainly in Germany. In 2009, Prof. Ernst was approached by a long-term client and asked to develop a scientifically robust method to value and benchmark entire patent portfolios of firms across industries and regions. This led to the development of the Patent Asset Index (Ernst, H., Omland, N. 2011. The Patent Asset Index – A New Approach to Benchmark Patent Portfolios, in: World Patent Information, Vol. 33, pp. 34-41). The Patent Asset Index developed by Prof. Ernst was the first patent-based metric that made it into the annual report of a leading firm such as the BASF in a very prominent form. The Patent Asset Index was endorsed and quickly adapted by many other firms as well, also outside the chemical industry.

“This method provides an accurate, overall view of the impact and efficiency of an enterprise’s investment in innovation.”Dr. William F. Banholzer, Former Executive Vice President and Former CTO, The Dow Chemical Company

“The method is valuable not only to demonstrate the importance of our patent portfolio to investors, but also to internally evaluate our patent strategy over time.” Dr. Andreas Kreimeyer, Former Member of the Board of Executive Directors and Former Research Executive Director, BASF

This big milestone led to the founding of PatentSight in 2009. PatentSight continued to develop a novel and unique back-end and front-end software solution for many sophisticated patent analytics applications, where the Patent Asset Index became the unique metric build into the proprietary PatentSight software. Today, the Patent Asset Index has become the scientifically proven standard to objectively value patents or larger patent portfolios. The EU commission, e.g., has used the Patent Asset Index to assess the impact of big mergers on innovation and competition in the chemical and pharmaceutical industries (Ernst, H., Guderian, C., Richter, M. 2020. The Innovation Environment and Knowledge Diffusion: Improving Policy Decisions through Patent Analytics. WTO Handbook on Trade in Knowledge (forthcoming)).

Based on its superior product and its solid scientific foundation, PatentSight became the market leader for patent analytics solutions in Europe. Prof. Ernst, based on his excellent contacts and reputation in Japan, initiated and helped to establish PatentSight Japan. That was an important strategic move for PatentSight because Japan is one of the most important markets for patent analytics software.

After selling his stake in PatentSight to RELX (Lexis Nexis), Prof. Ernst continues to do research in the field of patent analytics and valuation and he helps and supports PatentSight if he can and whenever time allows him to do so.

Insights for businesses

Insights for businesses –
Collaboration with companies.

The Chair of Technology and Innovation Management (TIM) maintains close contacts with companies from the business sector. The focus areas of this collaboration are the optimization of the new product development process, intellectual property management (patents and other commercial intellectual property rights), as well as strategic aspects of innovation management.

Publications for Managers

Our research always aims at generating new and actionable insights for managers. To extent our research to managers, we have published some of our research findings in journals that are mostly read by practitioners or experts in a specific field. Some of these publications have appeared in World Patent Information, MIT Sloan Management Review, California Management Review etc. Three sample publications include the following:

  1. Conley, J.G., Bican, P., Ernst, H., 2013. Value Articulation - A Framework for the Strategic Management of Intellectual Property, California Management Review - Special Issue on Intellectual Property Management, Vol. 55, Nr. 4, pp. 102-120.
  2. Siebdrat, F., Högl, M., Ernst, H. 2009. How to Manage Virtual Teams, in: MIT Sloan Management Review, Vol. 50 (4), pp. 63-68. (winner of the Robert Beckhard Memorial Prize of the MIT Sloan Management Review 2010).
  3. Ernst, H. 2003. Patent Information for Strategic Technology Management, in: World Patent Information, Vol. 25, Issue 3, pp. 233-242. (most frequently cited paper in WPI)

Case studies

We have written and published multiple, sometimes award-winning teaching case studies. These case studies are used in post-experience MBA and customized executive education programs to offer students and managers a novel, unique, relevant and actionable learning experience. Examples of these cases studies include:

  1. Ernst, H. Guderian, C. Bican, P. 2017. From crisis to world champion. Lessons from German football. More
  2. Guderian, C. Bican, P. 2016. Martin Bauer Group: Corporate social responsibility with Eindollarbrille. More
  3. Dubiel, A. 2009. How to build and manage a global R&D centre – The case of GE in India. More
  4. Kukreja, A., Dubiel, A. 2009. Paris-Piteşti – How the Dacia Logan is changing the innovation rules in the automotive industry. More


Prof. Ernst has done some podcasts to explain the relevance of his research to a larger audience, especially managers. Examples of these podcasts include:

  1. IP Fridays Podcast (2019) "Trends in Innovation and Patent Management" with Prof. Dr. Holger Ernst (EN). More
  2. TRENDONE Podcast (2021) "Die Eigenschaften der Top Innovatoren" with Prof. Dr. Holger Ernst (DE). More

Benchmarking Tools for Firms

Based on our research, we have built benchmarking tools for firms and managers to improve their innovation management: the Innovation Success Panel (ISP®) and the ipXellence Project.

The Innovation Success Panel (ISP®) benchmarks your firm on important success factors of innovations (product, service, business model innovation) against innovations leaders. This is a very efficient and scientifically proven method for firms to increase their innovativeness and the contribution of innovations to sales and profits. To find out more about the ISP® please download the following pdf-file: “IsP_Info_English”. For further information or inquiries please contact:

The ipXellence tool benchmarks your firm on multiple dimensions of excellence in Intellectual Property (IP) Management against leading firms in specific industries and across industries and regions, esp. Europe and USA (Japan is being currently added to the data base). This is a great tool  for firms to improve their IP management and to maximize financial and strategic value from their existing and future IP assets. To find out more about the ipXellence tool, please download the following pdf-file: “ipXellence”. For further information or inquiries please contact:


Within its teaching approach, the Chair aims to teach students the latest insights into international technology and innovation management. The curriculum should provide not only theoretical but also practically relevant knowledge - therefore, guest lectures are regularly integrated into teaching events. The curriculum is also based on the findings of the Chair's own research and is conveyed to the students by means of innovative and interactive teaching methods. The students will apply the acquired knowledge in practical exercises and case studies.
