FLSmidth Inc. v. Metso Finland Oy

Case Overview and Background: FLSmidth Inc. v. Metso Finland Oy (IPR2025-00985)

This Inter Partes Review (IPR) involves two prominent global players in the mining and aggregates industries: Petitioner FLSmidth Inc. and Patent Owner Metso Finland Oy. FLSmidth Inc., a subsidiary of the Danish multinational FLSmidth & Co. A/S, specializes in providing advanced technologies, equipment, and services for the global mining and cement industries, offering solutions for minerals processing, grinding, crushing, pumping, and separation with a focus on sustainability. Metso Finland Oy, a Finnish industrial machinery company and part of the broader Metso Corporation, supplies technology and services primarily for the mining and aggregates industries, including crushers, screens, grinding mills, and material handling equipment. Both companies are direct competitors, constantly innovating and protecting their intellectual property in the market for heavy industrial equipment.

The IPR challenged the validity of claims 1-26 of U.S. Patent No. 9,518,604, titled "CRUSHER AND WEAR PART FOR A CRUSHER." This patent generally relates to improvements in crushers, particularly focusing on wear parts designed to enhance the efficiency and longevity of such machinery used in mining and aggregates processing. While there is no specific accused product in an IPR proceeding, the context for this challenge likely stems from the intense competitive landscape and a history of intellectual property disputes between these companies concerning similar equipment. For instance, Metso Minerals Industries Inc. previously sued an FLSmidth subsidiary in 2007 for patent infringement and trade secret misappropriation related to cone crushers, specifically comparing Metso's HP400 rock crusher to FLSmidth-Excel's Raptor XL400.

This IPR was filed by FLSmidth Inc. with the United States Patent and Trademark Office's Patent Trial and Appeal Board (PTAB) on May 14, 2025. The procedural posture of the case is that the PTAB did not institute a trial on the challenged claims and the proceeding was subsequently terminated. The existing case summary indicates this termination was due to "procedural reasons." While the specific procedural grounds for IPR2025-00985 are not publicly detailed, common procedural issues leading to non-institution and termination at the PTAB include timeliness bars, real party-in-interest challenges, discretionary denials based on parallel district court litigation (e.g., Fintiv factors), or other policy considerations related to efficient use of resources and "settled expectations" in a patent. The case is notable as it reflects ongoing competitive dynamics between two major industrial equipment providers, where intellectual property challenges at the PTAB are a routine strategy to contest market positions and patent strength.

The provided case, FLSmidth Inc. v. Metso Finland Oy, IPR2025-00985, is an Inter Partes Review (IPR) proceeding before the Patent Trial and Appeal Board (PTAB) of the United States Patent and Trademark Office (USPTO), not a patent infringement litigation. The IPR challenged claims 1-26 of U.S. Patent No. 9,518,604. The proceeding was terminated without institution of a trial due to procedural reasons.

As of May 17, 2026, there is no public record of a parallel or related patent infringement litigation specifically asserting U.S. Patent No. 9,518,604 between FLSmidth Inc. and Metso Finland Oy. While there was a previous intellectual property dispute between FLSmidth and Metso Minerals Inc. (a subsidiary of Metso Corporation) concerning different patents and trade secrets in the U.S. District Court for the Eastern District of Wisconsin (case 2:2007cv00926), which settled in 2010, this older case is unrelated to the current IPR for patent 9,518,604.

The key legal developments and outcome for IPR2025-00985 are as follows:

• Filing of Petition (2025-05-14): FLSmidth Inc. filed a petition for Inter Partes Review, IPR2025-00985, challenging the validity of claims 1-26 of U.S. Patent No. 9,518,604, assigned to Metso Finland Oy.
• Termination Without Institution (Date not specified in provided information): The PTAB did not institute a trial, and the proceeding was terminated due to procedural reasons. While the exact date and specific procedural reasons for the termination of IPR2025-00985 are not immediately available in the search results, this period (2025) saw significant changes in IPR institution practices at the USPTO. Effective October 20, 2025, the USPTO Director reclaimed personal authority over all IPR and Post-Grant Review (PGR) institution decisions, moving towards a more restrictive, policy-driven regime often resulting in discretionary denials, sometimes without detailed explanations. It is plausible that the termination of IPR2025-00985 was a result of these evolving discretionary denial policies.

Despite a comprehensive search of public records, including general web searches for PTAB dockets and news related to IPR2025-00985, the specific counsel of record representing FLSmidth Inc. in this terminated Inter Partes Review could not be definitively identified.

Information regarding the attorneys, their roles (lead counsel, of counsel, local counsel, in-house), firms, office locations, and relevant patent litigation experience for this particular IPR is not readily available through the accessible public search results. While the PTAB's Open Data Portal exists, direct navigation to specific counsel filings for IPR2025-00985 was not successful using general search queries. As the proceeding was terminated without institution, detailed attorney information may not have been widely published or easily indexed by general search engines.

As of May 17, 2026, a comprehensive web search, including searches of the USPTO's Patent Trial and Appeal Board (PTAB) databases, Law360, and other legal news sources, has not yielded specific public records identifying the counsel of record representing Metso Finland Oy in IPR2025-00985.

While PTAB regulations require parties to designate lead and back-up counsel, with lead counsel being a registered practitioner, the public summaries and databases accessed do not contain a detailed listing of attorneys or their firms for this specific terminated IPR proceeding. The case was terminated without institution of a trial due to procedural reasons, which may limit the public availability of detailed counsel information compared to cases that proceed further into the IPR process.
