Having recently noted a perceived greater frequency of patent trials vs. other kinds of civil litigation, it is perhaps not all that surprising that Donaldson Co., Inc., which had been locked in patent litigation with Baldwin Filters, Inc. from 2004-2008 (District of Minnesota, Case No. 04-2679) (Donaldson having been represented by David Gross, of Faegre & Benson), this week shows up on the District of Minnesota docket again with a patent infringement case (represented by David Gross, of Faegre & Benson) against Baldwin Filters, Inc. (District of Minnesota, Case No. 09-cv-1049 (JMR/AJB).
Donaldson actually filed this most recent complaint back in May, but no summons issued until late August, and now Baldwin’s counsel, Laura Mitchell Friedmann (from Fredrikson & Byron (“the other F&B”)) has moved for a flotilla of pro hac vice motions for Chicago-based Kirkland & Ellis lawyers.
