Kyocera Corporation

Kyocera Corporation (TSE: 6971; NYSE: KYO) is a Japanese multinational ceramics and electronics manufacturer headquartered in Kyoto. Founded April 1, 1959 by Kazuo Inamori as Kyoto Ceramic Co., it is publicly listed and not a subsidiary of any other company. Per its own corporate profile (as of March 31, 2026), the group reported consolidated sales of ¥2,070,203 million (roughly $14B) and 73,856 employees across 279 group companies.

Products / operations. Kyocera is an operating company spanning several segments: fine ceramic components (semiconductor processing equipment parts, automotive components, sapphire substrates); semiconductor-related parts including ceramic and organic IC packages; electronic components (ceramic and tantalum capacitors, crystal/timing devices, connectors, RF modules, power semiconductors, via subsidiary Kyocera AVX); document solutions (ECOSYS printers and multifunctional peripherals); communications equipment and IoT/M2M modules; automotive components; solar modules, storage batteries and energy systems; medical devices such as prosthetic joints and dental implants; and cutting tools.

Patent-litigation posture. Kyocera appears in the tracked data as a pure defendant — 1 case, 0 as plaintiff — consistent with an operating company being targeted rather than an active two-way litigant. Its sole tracked suit sits in the plaintiff-friendly U.S. District Court for the Eastern District of Texas.

Notable case. Monument Peak Ventures, LLC v. Kyocera Corporation (2:23-cv-00127, E.D. Tex., filed March 27, 2023) asserted five patents covering digital imaging, camera power management, and print-job workload distribution, and accused over 30 products including Kyocera smartphones (DuraForce, DuraSport, DuraSlate) and ECOSYS multifunction printers plus Cluster Printing Pro software. Monument Peak Ventures is characterized by Unified Patents as a non-practicing entity and Dominion Harbor entity asserting an acquired portfolio. The case was dismissed with prejudice on December 14, 2023 (reported as settled), 263 days after filing. No other Kyocera appearances are tracked.
