Before PROST, Chief Judge, BRYSON and WALLACH, Circuit Judges.

PROST, Chief Judge.

PI Advanced Materials Co., Ltd., formerly known as SKC Kolon PI, Inc. (“SKPI”) filed a declaratory judgment action against Kaneka Corp. (“Kaneka”) in the United States District Court for the Central District of California seeking a declaration of non-infringement of Kaneka’s U.S. Patent No. 7,691,961 (“the ’961 patent”). Kaneka counterclaimed for induced infringement of the ’961 patent and U.S. Patent Nos. 9,441,082 (“the ’082 patent”) and 6,264,866 (“the ’866 patent”).

The district court granted summary judgment of non-

infringement. For the SKPI products at issue on appeal, the district court concluded that no reasonable jury could find that they were imported into the United States, which meant that Kaneka could not prove the underlying direct infringement essential to its inducement claims. Kaneka appeals. We affirm.

BACKGROUND

I

Kaneka and SKPI are competitors in the manufacture and sale of polyimide film, which is used in mobile phones. The film is incorporated into mobile phones through a multitiered supply chain. First, a polyimide film manufacturer , such as Kaneka or SKPI, makes the film and sells it to a laminate manufacturer. Second, the laminate manufacturer laminates the film to form flexible copper clad laminates (“FCCLs”) and sells those to a circuit board manufacturer. Third, the circuit board manufacturer uses the FCCLs to make flexible printed circuit boards (“FPCs”)

and sells those to a module maker. 1 Fourth, the module maker incorporates the FPCs into modules (i.e., components of a mobile phone, such as a display or camera) and sells the modules to a set manufacturer. Fifth, and finally, the set manufacturer (e.g., Apple or Samsung Electronics) incorporates the modules into mobile phones.

Kaneka and SKPI have litigated before. In Kaneka Corp. v. SKC Kolon PI, Inc., No. 2:11-cv-03397 (C.D. Cal.) (“the 3397 case”), Kaneka alleged that SKPI induced infringement of the ’961 patent (among others) in the form of U.S. importation of certain accused SKPI films—in particular , certain film types bearing prefixes “IF,” “LN,” and “LV” (collectively, “the older films”). In that case, Kaneka relied on its expert Mr. Napper to trace the amount of square meters of the older films that was reasonably likely to have progressed through each stage of the supply chain. In November 2015, a jury found that SKPI induced infringement of the ’961 patent as to the older films.

Following the jury verdict, in January 2016, SKPI announced to its customers that “through its continued R&D efforts, [it] ha[d] developed more efficient and stable manufacturing processes . . . to provide polyimide films with improved film properties and cost savings to its customers .” J.A. 16199. SKPI also informed its customers that “[w]ith this change, . . . the existing product types IF and LN, and LV will be supplied as types GF and GV respectively which are the new integrated nomenclatures.” J.A. 16199.

SKPI filed the present action in August 2016, seeking a declaratory judgment that its alleged redesigned films do

not practice the claims of the ’961 patent and that its actions relating to those films do not infringe the patent. Kaneka counterclaimed for induced infringement of the ’961, ’082, and ’866 patents. Kaneka’s infringement allegations concerned ten SKPI film types relevant here: GF030 (7.5 µm), GF040 (10 µm), GF050 (12.5 µm), GF100 (25 µm), GF200 (50 µm), GF300 (75 µm), GV050 (12.5 µm), GV100 (25 µm), GV200 (50 µm), and GV300 (75 µm) (collectively, “the accused films”). 2 It is undisputed that SKPI did not begin making and selling the accused films before January 2016.

Following fact and expert discovery, SKPI moved for summary judgment of non-infringement. SKPI argued that Kaneka could not prove the direct infringement required for its inducement claim because it lacked evidence that the accused films were imported into the United States. After holding two hearings on the summary-judgment motion, as well as entertaining a supplemental brief from Kaneka (and a response from SKPI), the district court issued a thorough order granting summary judgment for SKPI.

As to the accused films generally, the district court began by observing that Kaneka lacked any direct evidence of importation; rather, it presented only circumstantial evidence about the supply chain from SKPI’s manufacture of the films to the mobile phones that are ultimately imported into the United States. The court also contrasted the evidence of importation in this case with that presented in the 3397 case. It noted that, unlike the 3397 case, where Mr. Napper’s expert report contained “some significant

2 Although Kaneka accused additional film types as infringing, the district court granted summary judgment for SKPI as to these types (albeit on different grounds), J.A. 21308–09, and Kaneka has not appealed the summary judgment as to these types.

analysis” tracing the amount of square meters of the film at issue that was reasonably likely to have progressed through each stage of the supply chain, “neither [Mr.] Napper nor Kaneka’s infringement expert . . . present[s] a comparable analysis.” J.A. 21310. Indeed, the court noted that Kaneka’s infringement expert report did “not address the issue of whether the accused films are imported into the United States at all.” J.A. 21310.

The court then analyzed the evidence Kaneka did put forth. Although Kaneka emphasized SKPI’s relationship with two large Korean FCCL manufacturers, the court observed that Kaneka lacked evidence about what happens to the accused films next—including whether the FPC and module makers use other film or other FCCL manufacturers (including from outside Korea), or whether there was a specific thought process relating to what mobile phones with what materials from certain suppliers would be sold where. The court also noted that Kaneka’s estimates of SKPI’s market share and other general statistics were “overwhelmingly based” on evidence that pre-dated when SKPI actually began making and selling the accused films. See J.A. 21313. After carefully considering Kaneka’s evidence , the court deemed it insufficient to raise a question of material fact to support Kaneka’s inducement claims. J.A. 21316.
