Kyocera's operations span diverse product lines across its Core Components, Electronic Components, and Solutions business segments. The company manufactures industrial ceramics, semiconductor packages, and automotive components. It also produces electronic components such as capacitors, connectors, and power semiconductors.

In terms of patent litigation, Kyocera Corp. maintains a posture typical of an operating company defending its products and services against patent assertions. The single tracked case, Kyocera Corp. v. SoftView LLC, shows Kyocera as the plaintiff in a Patent Trial and Appeal Board (PTAB) proceeding. This case represents Kyocera's defensive action of initiating an Inter Partes Review (IPR) to challenge the validity of patents asserted against it.

The case Kyocera Corp. v. SoftView LLC (IPR2013-00004 and IPR2013-00007) began after SoftView LLC, identified as a patent assertion entity, sued Kyocera and other mobile phone manufacturers for patent infringement in district court. Kyocera's IPR petition led to the PTAB finding a reasonable likelihood that Kyocera would prevail in its challenge to certain claims of SoftView's U.S. Patent No. 7,461,353. Subsequent legal proceedings, including appeals to the Federal Circuit, further clarified the scope of patent owner estoppel in IPRs.
