Lichtenthaler co-author Ernst retracts paper that didn’t include Lichtenthaler

research policy 1A frequent co-author of Ulrich Lichtenthaler — the management professor who has retracted at least eight papers — has now withdrawn one of his own from Research Policy.

The original paper, “How to create commercial value from patents: The role of patent management,” by Holger Ernst and colleagues, went online on May 21, 2012. Here’s the notice:

This article has been withdrawn at the request of the authors and editor. The Publisher apologizes for any inconvenience this may cause.

Ernst’s name was removed from a paper he and Lichtenthaler co-authored in the Journal of Product Innovation Management.

Ernst didn’t respond to a request for comment, but Elsevier, which publishes Research Policy, sent us this explanation:

After the paper by Ernst et al. had been accepted for publication (but before it was formally published with a volume and page number), the attention of the Research Policy Editors was drawn to certain statistical problems. When asked about these, the authors stated that the statistical errors had been inadvertently made when a revised version of the paper was being prepared in response to referees’ comments on the original version. In line with Elsevier procedures for handling ‘articles in press’, it was therefore decided to withdraw the paper.

Hat tip: Thanks to a number of commenters and people on Twitter for bringing this withdrawal to our attention.

One thought on “Lichtenthaler co-author Ernst retracts paper that didn’t include Lichtenthaler”

  1. What kind of “statistical errors” were there? Comparable to the errors made in his papers with Lichtenthaler?
