In the latest issue of IAM magazine – available for subscribers to view online from today – Matthew Beers and Maria Lazarova of Ocean Tomo take a deep-dive look at patent abandonments data from both the USPTO and EPO. The full article contains a wealth of interesting data but, for the purposes of this blog we’ll take a sneak peek at the findings relating to IP owners and which of them abandon the most patents at both agencies. Perhaps unsurprisingly, about half of the top 50 companies by abandonment volume are also in the top 50 by number of applications filed. What’s more, of the top 50 companies by abandonment volume over the period examined by Beers’ and Lazarova’s analysis, well over two-thirds appear among the top abandoners at both the USPTO and the EPO.
