IP Law Daily, PATENT—Fed. Cir.: Mixed results for Philips in wearable device infringement lawsuit against Garmin, (Aug 15, 2024)

By Saurabh Kashyap, B.A., LL.B., LL.M.

Invalidity ruling on one patent upheld as indefinite; non-infringement ruling on the other vacated due to unresolved material facts.

The U.S. Court of Appeals for the Federal Circuit affirmed in part and vacated in part a federal district court’s decision in a patent infringement lawsuit filed by Philips North America, LLC against Garmin International, Inc,. The appellate court upheld the district court’s invalidity ruling for one of the asserted patents due to indefiniteness but vacated the summary judgment of non-infringement concerning the other asserted patent due to unresolved material facts (Philips North America, LLC v. Garmin International, Inc., No. 22-2255 (Fed. Cir. Aug. 15, 2024)).

Background. The plaintiff/appellant, Philips North America, LLC, is a prominent player in the healthcare technology industry and is known for its health monitoring and fitness device innovations. The defendant/appellee, Garmin International, Inc., is a global leader in GPS technology and wearable fitness trackers.

Philips owns the asserted U.S. Patent Nos. 6,013,007 (the ’007 patent) and 8,277,377 (the ’377 patent). The ’007 patent relates to a Global Positioning System (GPS)- based athletic performance monitor designed to provide real-time feedback to athletes, while the ’377 patent covers a method and apparatus for wireless monitoring of exercise and physiological data via a web-enabled device.

Philips filed this lawsuit alleging that Garmin's wearable fitness trackers infringed on both the ’007 and ’377 patents. The district court ruled that the asserted claims of the ’007 patent were invalid due to indefiniteness, primarily because the patent failed to disclose a sufficient algorithm for computing certain types of athletic performance feedback data. The court also granted summary judgment in favor of Garmin, finding no infringement of the ’377 patent. Philips appealed both determinations.

Claim construction dispute. The Federal Circuit reviewed the district court's claim construction of the ’007 patent, particularly the term “means for computing athletic performance feedback data from the series of time-stamped waypoints obtained by said GPS receiver.” The district court had agreed with Garmin’s broader interpretation, which included calculating various performance metrics such as calories burned, which Philips argued was outside the scope of the asserted claims.

In affirming the district court's ruling, the Federal Circuit cited the importance of providing a straightforward algorithm for any means-plus-function claim under 35 U.S.C § 112 ¶ 6. The court referred to the precedent in Noah Sys., Inc. v. Intuit Inc., 675 F.3d 1302, 1318 (Fed. Cir. 2012), which emphasized the necessity of disclosing an algorithm for performing the specified function. Thus, the Federal Circuit found that the ’007 patent lacked such disclosure, rendering the patent indefinite.

Infringement analysis. Regarding the ’377 patent, the Federal Circuit vacated the district court's summary judgment of non-infringement. The key question was whether Garmin's devices infringed on the patent by uploading physiological data while the user exercised. Philips contended that the data, including heart rate, was synced during exercise, thereby meeting the patent’s requirements.

The appellate court highlighted the existence of a genuine dispute of material fact regarding the syncing of data during exercise, which precluded summary judgment. The court referenced Lucent Techs., Inc. v. Gateway, Inc., 580 F.3d 1301, 1334–35 (Fed. Cir. 2009), which addressed how the frequency or amount of use of a patented method is more appropriate for determining damages rather than infringement. The court also pointed out the need to evaluate Garmin’s intent to induce infringement, citing Warner-Lambert Co. v. Apotex Corp., 316 F.3d 1348, 1364 (Fed. Cir. 2003), which requires proof of specific intent to encourage infringement.

Conclusion. The appellate court, therefore, affirmed the district court’s indefiniteness determination as to claims 1 and 21 of the ’007 patent and vacated and remanded the summary judgment of non-infringement of claim 1 of the ’377 patent.

The Case is No. 22-2255.
