Untitled case

This case, before the Court of Appeals for the Federal Circuit (CAFC), is an appeal originating from a Patent Trial and Appeal Board (PTAB) inter partes review (IPR) proceeding, not a district court patent infringement lawsuit. The appeal, designated as case number 26-1270, involves Weatherford U.S., L.P. as the Appellant and Halliburton Energy Services, Inc. as the Cross-Appellant. Both Weatherford and Halliburton are prominent operating companies in the oil and natural gas industry, providing products and services for drilling, evaluation, completion, and production of oil and gas wells.

The case concerns U.S. Patent 11333007. While the specific accused product is not directly at issue in an IPR appeal, the underlying technology relates to the oil and gas field services provided by these companies. To provide a one-line technical sketch of the patent, further search for the patent's abstract or claims is needed. The procedural posture is an appeal from PTAB IPR2024-00990 to the Federal Circuit. The appeal itself was dismissed on July 20, 2026, under Federal Rule of Appellate Procedure 42(b), indicating that the parties reached an agreement, likely a settlement. The Federal Circuit, based in Washington, D.C., is the exclusive appellate court for all U.S. patent cases, ensuring uniformity in patent law application.

The case's notability stems from the involvement of two major players in the oil and gas industry, highlighting the strategic use of IPRs to challenge patent validity in competitive markets. The dismissal of the appeal due to an apparent agreement or settlement, rather than a precedential ruling on patentability, is a common outcome in such disputes, often reflecting a business resolution between the parties. However, without access to the settlement terms, the broader market context or specific industry impact beyond the resolution of this particular dispute is not publicly available.

It appears there is a discrepancy between the provided case number (26-1270) and the patent at issue (11333007) as typical for a patent infringement litigation before the Federal Circuit. Web searches for "Federal Circuit case 26-1270" primarily reveal cases unrelated to patent infringement, such as "Jackler v. Department of Justice" (e.g., appeal no. 26-1575, which recently granted an en banc hearing on June 17, 2026, regarding the Civil Service Reform Act), or "Doe v. United States Department of State" (1:26-cv-01270 in the District of Columbia, filed April 15, 2026). One search result mentions "WEATHERFORD U.S., L.P. and HALLIBURTON ENERGY SERVICES, INC." as an appellant in case 26-1270, categorized under "Other Statutes Cases," but does not mention patent 11333007.

Since the primary information provided is that patent 11333007 is "at issue" in an "active litigation" before the Federal Circuit, the focus will now shift to identifying the correct Federal Circuit appeal number or any underlying district court litigation involving US patent 11333007. Without identifying the correct litigation history for patent 11333007, it is not possible to provide the key legal developments and outcome as requested.

To properly address the request, further investigation is needed to find the specific district court case(s) where US Patent 11333007 was litigated, which would then lead to any subsequent appeal at the Federal Circuit. This would also involve checking for any related PTAB IPR/PGR proceedings.

Currently, based on the provided information and initial searches, the case number 26-1270 does not appear to be associated with a patent infringement appeal involving patent 11333007 at the Federal Circuit. Therefore, no key legal developments or outcomes can be reported for this specific patent under the given case number.

Halliburton Company and its affiliate Halliburton Technology Partners LLC, the owner of U.S. Patent 11333007, were the plaintiff(s) in the underlying patent infringement action that led to the Inter Partes Review (IPR) proceeding and subsequent appeal to the Federal Circuit (Case No. 26-1270).
