Professional Profile

Mark Pals is a senior member of Kirkland's pharmaceutical and biotech patent litigation practice and of the Firm's Intellectual Property Practice Group. Mark has tried cases before juries and judges across the country, and has secured verdicts and settlements in cases with billions of dollars at stake. He has a Ph.D. in biophysics and focuses his practice on life sciences and chemical patent litigation, but represents clients across a broad range of industries. His cases have involved pharmaceuticals, medical devices, gene expression, protein synthesis, DNA cloning and sequencing, DNA array technology, chemical processes, semiconductor manufacturing, fuel and oil filters, and other technologies. In addition, Mark has represented his clients in a wide variety of trademark and unfair competition cases.

Mark's trial successes and litigation skills have been repeatedly recognized by industry publications and reports. In selecting him for its "IAM Patent 250," Intellectual Asset Management (IAM) magazine states that he is an "incredibly smart biotech and pharmaceutical patent litigator." As Chambers USA reports in America's Leading Lawyers for Business 2011: Life Sciences, "He's a skillful attorney in front of the judge and jury." Legal 500 praises him as a recommended attorney for his "excellent legal instincts" and his thoughtfulness on client issues. Mark was distinguished as one of The Best Lawyers in America 2013–2016 in the field of Litigation - Patent. The American Lawyer featured Mark's work in their 2008 article selecting Kirkland's IP practice as a finalist in their "IP Litigation Department of the Year" survey. The article quotes one client as stating, "I'd say, without hyperbole, there is not a smarter IP litigator than Mark Pals." In addition, IP Law & Business profiled his jury trial wins for Third Wave Technologies in their article entitled "The DNA of a Patent Case."

His appellate practice primarily concentrates on appeals in the Federal Circuit. Representative matters include the affirmances by the Federal Circuit of non-infringement judgments he obtained for his clients Amgen (see 2009 WL 1528551) and Third Wave Technologies (see 2009 WL 886301) in separate cases.

Mark is active in pro bono matters, and has represented individuals and charitable institutions in a variety of litigations.
