Untitled case

This is a Post-Grant Review (PGR) case, PGR2025-00055, filed at the USPTO Patent Trial and Appeal Board (PTAB) against US patent 12089543. The case has been instituted and is currently pending.

The patent owner is Fienile Agronegocios Ltda, a Brazilian operating company specializing in agricultural technology, particularly innovative irrigation systems with artificial outdoor lighting aimed at increasing crop productivity. The petitioner for this specific PGR, PGR2025-00055, is not publicly identified in the available records. The asserted patent, US Patent 12089543, is titled "System and method of agricultural management." It technically describes a modular agricultural irrigation pivot-like device equipped with artificial LED lighting sources that can adjust spectral bands for crop cultivation, alongside determining and implementing irrigation and light supplementation routines.

The procedural posture of this case is a Post-Grant Review before the PTAB. The petition for PGR2025-00055 was filed and subsequently instituted on December 1, 2025. This institution decision, along with others, marked the first set of IPRs and PGRs instituted under the tenure of Director John A. Squires, who assumed the role in September 2025. Under recent procedural changes effective October 20, 2025, the Director, in consultation with at least three PTAB judges, now makes all institution decisions for IPR and PGR proceedings, evaluating discretionary and merits-based considerations. [cite: 5, 7, 12 from prior steps]

This case is notable as one of the initial PGRs to be instituted under the new leadership of Director Squires, providing an early indication of the PTAB's approach to institution decisions, including factors related to discretionary denials. At the time of its institution, PGR2025-00055 did not involve any co-pending litigation. [cite: 3 from prior steps]

The user is asking for key legal developments and the outcome of the patent infringement litigation related to US patent 12089543, which is currently subject to a pending PGR (PGR2025-00055).

I need to search for any associated district court litigation involving this patent and its owner, Fienile Agronegocios Ltda. I will then chronologically list the key events as requested.

Given the existing information states, "At the time of its institution, PGR2025-00055 did not involve any co-pending litigation. [cite: 3 from prior steps]", I need to specifically look for any subsequent litigation, or confirm that no such litigation has yet arisen. The current date is May 19, 2026, and the PGR was instituted on December 1, 2025. It's possible litigation has started since institution or that the information about no co-pending litigation at the time of institution is still true.

My search queries will focus on:

1. Identifying any district court litigation involving US patent 12089543.
2. Identifying any district court litigation involving Fienile Agronegocios Ltda as a plaintiff.
3. Looking for updates on PGR2025-00055 to see its current status and if any related litigation has been identified since the prior update.## Key Legal Developments and Outcome for US Patent 12089543

As of May 19, 2026, US Patent 12089543, owned by Fienile Agronegocios Ltda, is currently active and subject to a Post-Grant Review (PGR) proceeding, PGR2025-00055, before the Patent Trial and Appeal Board (PTAB). While the patent family has "known litigation" and "the first worldwide family litigation has been filed," specific details regarding any parallel U.S. district court patent infringement litigation involving Fienile Agronegocios Ltda as a plaintiff asserting US Patent 12089543 are not publicly identified in the available records. The previous case summary noted that "At the time of its institution, PGR2025-00055 did not involve any co-pending litigation."

The key developments so far relate to the PTAB's PGR proceeding:

• PGR Filing and Institution: The Post-Grant Review case, PGR2025-00055, was filed against US Patent 12089543 by petitioner Almendra Pte. Ltd. on June 16, 2025. The petition was subsequently instituted on December 1, 2025, marking one of the first PGRs instituted under Director John A. Squires. The case is currently in a "Trial Instituted" status. The last recorded filing in the PGR case was on December 17, 2025.

Without further information on any specific U.S. district court litigation, it is not possible to detail filing and initial pleadings, pre-trial motions, claim construction, discovery, trial events, or final disposition for such a case. The primary legal development concerning US Patent 12089543 remains the ongoing PGR proceeding at the PTAB.

As of May 19, 2026, there is no publicly identified U.S. district court patent infringement case where Fienile Agronegocios Ltda is a plaintiff asserting US Patent 12089543. The previous summary noted that "At the time of its institution, PGR2025-00055 did not involve any co-pending litigation." Therefore, information on counsel for a "plaintiff" in such a case cannot be provided.

However, in the ongoing Post-Grant Review (PGR) proceeding, PGR2025-00055, at the Patent Trial and Appeal Board (PTAB), the parties are the Petitioner, Almendra Pte. Ltd., and the Patent Owner, Fienile Agronegocios Ltda. Specific counsel of record for these parties in PGR2025-00055 are not readily available in the provided search results. Further detailed docket searching would be required to identify the specific attorneys and their firms representing Almendra Pte. Ltd. and Fienile Agronegocios Ltda in this particular PGR.

As of May 19, 2026, no U.S. district court patent infringement case asserting US Patent 12089543 has been publicly identified. Consequently, there are no named defendants or corresponding defense counsel to report in such a litigation. The previous case summary explicitly stated that "At the time of its institution, PGR2025-00055 did not involve any co-pending litigation," and no subsequent related infringement litigation has been identified in public records.

The only active proceeding involving US Patent 12089543 is the Post-Grant Review (PGR) case, PGR2025-00055, at the USPTO Patent Trial and Appeal Board (PTAB). In this PGR, Fienile Agronegocios Ltda is the Patent Owner, effectively "defending" its patent against the Petitioner, Almendra Pte. Ltd. While specific counsel of record for Fienile Agronegocios Ltda in PGR2025-00055 are not readily available in general search results, identifying them would require direct access to the PTAB's PRPS docket for PGR2025-00055.
