1 case as defendant.
Technoprobe S.p.A. is a leading Italian company in the semiconductor and microelectronics sector, specializing in the design and production of probe cards. Founded in 1996, the company is headquartered in Cernusco Lombardone, Italy. Technoprobe is a publicly traded company, listed on the Euronext Milan exchange under the ticker TPRO. The company operates globally, with numerous locations across Europe, Asia, and the United States. As of early 2026, Technoprobe had approximately 3,000 employees and a market capitalization of around €13 billion. For the fiscal year 2025, the company reported revenues of approximately €628.4 million.
Technoprobe is an operating company that designs, develops, and manufactures probe cards. These devices are highly technological electro-mechanical interfaces used for the functional testing of integrated circuits (chips) while they are still on the silicon wafer. The company's products are a critical component in the semiconductor manufacturing supply chain, ensuring the reliability of chips used in applications such as 5G, artificial intelligence, data centers, automotive, and consumer electronics. Technoprobe offers a comprehensive portfolio of technologies, from cantilever to vertical MEMS probe cards, to meet diverse testing requirements. It is considered the second-largest manufacturer of probe cards in the world by revenue and volume.
Based on the provided data, Technoprobe S.p.A. is an operating company that has been named as a defendant in patent litigation. The single tracked case, MPI Corp. v. Technoprobe SPA, was filed in the Eastern District of Texas, a venue known for patent litigation. This defensive posture is typical for a manufacturing company in a competitive technology sector. The plaintiff, MPI Corp., is also a global technology company involved in semiconductor testing solutions, suggesting this is a dispute between direct competitors.
The sole tracked lawsuit was filed on April 17, 2026, by MPI Corporation, a Taiwan-based competitor in the semiconductor test and measurement industry. The complaint alleges that Technoprobe's probe cards infringe on two of MPI's U.S. patents related to wafer probing methods. This litigation appears to be part of a broader, ongoing intellectual property dispute between the two companies, as MPI has also publicly announced that Technoprobe filed a motion for a provisional injunction against them in a Taiwanese court around the same time. This context indicates an active and international competitive dynamic between the two firms in the specialized market for semiconductor probe cards.
The accused products are Technoprobe's probe cards, specifically those from its HiP Architecture product line.
