Court Rejects “Touch Base” Approach—Applies Foreign Privilege Law to Communications with Patent Agents

In a patent-infringement action, the question arose whether the attorney–client privilege protected documents discussing legal advice of the defendant’s Swedish predecessor. And then a second, threshold question arose: whether Swedish or U.S. law governed the privilege issue.

In a break from other federal courts, the Court for the ND ILL, “as a matter of comity,” applied a “functional approach” and determined that Swedish privilege law governed the discovery dispute. And applying Swedish privilege law, the Court found the documents unprotected. Baxter Int’l, Inc. v. Becton, Dickinson & Co., 2019 WL 6258490 (ND Ill. Nov. 22, 2019). You may read the opinion here.

U.S. or Swedish Law?

Becton Dickinson (BD) acquired Carmel Pharma, a Swedish company, in 2011. In its patent-infringement lawsuit against BD, Baxter International moved to compel documents “that purportedly reflect legal advice provided to Carmel Pharma … or its employees about patent-related issues.”

BD refused, arguing that, under the so-called “touch base” approach, U.S. privilege law applied. And that under In re Queen’s Univ. at Kingston, 820 F.3d 1287, 1295 (Fed. Cir. 2016), the attorney–client privilege covers a company’s communications with a foreign patent agent.

The Touch Base Approach

The “touch base” approach is a choice-of-law doctrine. Under this doctrine, courts apply the privilege law of the country with the predominant or compelling interest in whether the communications are non-discoverable.  The predominant interest lies either in (1) the country where the lawyer and employee entered the putatively privileged relationship, or (2) the country that was the relationship’s center at the time they communicated.

Generally, U.S. privilege law applies to communications concerning U.S. proceedings, and foreign privilege law applies to communications related to foreign legal proceedings.

The Functional Approach

Courts in the Northern District of Illinois have faced this choice-of-law issue a handful of times, and consistently take a different approach to privilege application to communications with foreign patent agents. In SmithKline Beecham Corp. v. Apotex Corp., 193 F.R.D. 530, 535 (ND Ill. 2000), the Court recognized this was a “rather unsettled area of law” and that district courts take “several approaches to arrive at an answer.”

Seeing a different trend, the SmithKline court said that, as a matter of comity, “and as a functional approach to the problem,” it would look to the “foreign nation’s law to determine the extent to which the privilege may attach.”

In Alfdex AB v. Hengst SE & Co., No. 14-CV-50038 (ND Ill. Oct. 15, 2014), available here, both plaintiff and defendant argued for application of the touch base approach. But the Court found no support in the Seventh Circuit for the touch base approach and, instead, followed SmithKline’s comity-functionalism approach.


The Baxter Court noted that “BD fails to sincerely acknowledge that courts in this district have decided to forego the ‘touching base’ test.” It then ruled—

Following the comity/functional approach utilized by courts in this district, we do as well, and we apply the law of the foreign nation, Sweden, to determine whether the Swedish Documents are protected by the attorney–client privilege.
