Componex Corporation (“Componex”) vs. EFI Componex, Inc. is a manufacturer of rolls used in machines handling continuous sheets of product and is a supplier for certain products in our VUTEk product line. In May 2013, Componex filed an action in the United States District Court for the Western District of Wisconsin alleging that rolls supplied to EFI by other vendors infringe two patents held by Componex. We moved for summary judgment that, among other things, Componex’s patents are not valid and that, even if they are, the rolls supplied and used in our products do not infringe the patents. Componex also moved for summary judgment of infringement. In November 2014, the district court granted summary judgment that one of the two patents at issue is invalid, that there is no evidence of infringement of the other patent at issue, and entered judgment in favor of EFI. In December 2014, Componex filed its notice of appeal to the United States Court of Appeals for the Federal Circuit. The Court of Appeals heard arguments in this case on October 7, 2015 and affirmed the district court’s judgment in EFI’s favor on October 16, 2015. As a result of the Court of Appeals decision, we believe that the likelihood that we will incur a loss in this matter is remote. Other Matters As of September 30, 2015, we were subject to claims, lawsuits, investigations, and proceedings in addition to the matter discussed above. There is at least a reasonable possibility that additional losses may be incurred in excess of the amounts that we have accrued. However, we believe that these claims are not material to our financial statements or the range of reasonably possible losses is not reasonably estimable. Litigation is inherently unpredictable, and while we believe that we have valid defenses with respect to legal matters pending against us, our financial statements could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies or because of the diversion of management’s attention and the incurrence of significant expenses.
