Weber Inc. v. Provisur Technologies: Federal Circuit Splits on 7 Food Slicing Patents
Weber Inc. and its affiliates challenged Provisur Technologies across seven patents covering industrial food slicing, packaging, and conveyor automation. After 611 days on appeal, the Federal Circuit issued a split decision — affirming in part, reversing in part, and remanding — leaving key infringement and validity questions unsettled.
A high-stakes split ruling across industrial food automation IP
Weber Inc., Weber Food Technology GmbH, Textor Inc., and associated German entities filed appeal No. 23-1438 on January 30, 2023, seeking Federal Circuit review of a district court infringement ruling against Provisur Technologies, Inc. The dispute centers on seven U.S. patents spanning fill-and-pack apparatus, optical grading, servo-controlled conveyors, sheet interleavers, and yield monitoring systems — core technologies in high-throughput industrial food slicing lines.
On October 2, 2024, the Federal Circuit issued a verdict of ‘affirmed-in-part, reversed-in-part, and remanded,’ simultaneously closing part of the appeal as dismissed. This mixed disposition means Weber prevailed on some claim constructions or validity positions, Provisur prevailed on others, and the lower court must revisit the remaining issues. Neither side achieved a complete appellate win, and the commercial stakes around several product lines remain in dispute.
A 611-day resolution suggests the breadth and technical complexity of seven patents across multiple product categories required extensive briefing and likely oral argument. The partial reversal is commercially significant: products Provisur sells that were cleared below may now face renewed scrutiny, while products that survived Weber’s appeal remain contested at remand. The public record does not disclose which specific patents drove the reversal versus the affirmance, nor the precise remand instructions — factors that will govern the next phase of this litigation.

Federal Circuit splits the decision: what affirmed-in-part, reversed-in-part, and remanded means
What ‘affirmed-in-part, reversed-in-part, and remanded’ means
A split Federal Circuit disposition means the panel found no reversible error in some aspects of the lower court’s ruling (affirmed) but identified legal error in others (reversed). The remand instruction sends the case back to the district court to address the reversed portions under the Federal Circuit’s corrected legal framework. This is a common outcome in multi-patent appeals — it preserves some findings while requiring fresh adjudication of others.
Partial appellate reversalWeber wins on some claims — but the case is not over
Weber and its affiliates secured a reversal on at least part of the lower court’s findings, meaning the Federal Circuit agreed with Weber’s position on one or more patents or claim constructions. Those reversed issues return to the district court, potentially reinstating infringement liability or narrowing Provisur’s invalidity defenses. However, the affirmed portions lock in whatever adverse findings Weber received below, limiting the scope of any remand victory.
Partial win — remand pendingProvisur retains some wins but faces renewed district court exposure
Provisur successfully defended the affirmance of certain lower court findings in its favour, providing some insulation from Weber’s full claim set. However, the reversal on other issues means Provisur must relitigate those questions at the district court level under revised legal standards. The partial dismissal of the appeal further narrows the active battleground, but Provisur cannot treat the case as resolved — infringement exposure on reversed claims remains live.
Partial defeat — remand riskSeven-patent portfolio creates persistent IP overhang for food slicing equipment makers
For manufacturers and integrators of industrial food slicing, packaging, and conveyor systems, this split ruling signals that Weber’s IP portfolio remains potent and actively enforced. The remand keeps uncertainty alive around key product categories — servo conveyors, sheet interleavers, optical graders, and yield monitors. Competitors and OEM suppliers operating in this space should treat these patents as live enforcement risks until the district court resolves the remanded issues.

Official order — verbatim text
The verdict phrase ‘affirmed-in-part, reversed-in-part, and remanded’ is a compound Federal Circuit disposition applied across a multi-patent record. The appellate standard of review for claim construction is de novo; for underlying factual findings it is clear error. A reversal under de novo review suggests the panel found a legally incorrect claim construction or legal standard applied below — not merely a factual disagreement. The simultaneous partial dismissal implies that at least one issue was not reached on its merits, potentially due to standing, mootness, or a party concession. The remand scope — whether limited to specific patents or broader — will govern the district court’s next phase and determine which product lines face renewed infringement adjudication.
Seven U.S. patents covering industrial food slicing and packaging automation
The seven asserted patents — US8322537, US6669005, US9399531, US6320141, US6997089, US7065936, and US7533513 — collectively cover the core automation stack of a modern industrial food slicing line. Earliest priority dates trace to application numbers filed in the late 1990s and 2000s, reflecting foundational IP in a sector that underwent significant mechanisation during that period. The portfolio spans fill-and-pack apparatus and methods, optical grading for quality control, servo-controlled conveyors for distribution, sheet interleavers for portion packaging, and yield monitoring — together representing substantially the full workflow of a high-throughput cold-cut or cheese slicing operation.
Weber’s willingness to assert all seven patents simultaneously in a single action against Provisur — a direct commercial competitor — signals a portfolio enforcement strategy aimed at establishing market boundaries rather than monetising a single innovation. For the food processing equipment sector, the Federal Circuit’s partial reversal confirms that at least some of Weber’s claim constructions were valid, raising the bar for Provisur and similarly situated manufacturers. Companies supplying conveyor, interleaver, or optical grading modules to food processors should audit their component specifications against this portfolio before the remand phase produces new district court findings.
Should you run an FTO against Weber’s 7-patent food slicing portfolio?
Any company developing or supplying industrial food slicing equipment, packaging machinery, servo distribution conveyors, optical grading systems, or sheet interleavers should treat this portfolio as a live enforcement risk. The Federal Circuit’s partial reversal indicates these patents are not easily invalidated — and Weber has demonstrated both the will and the resources to litigate to the appellate level. R&D teams building next-generation slicing or portion-packing lines should conduct freedom-to-operate analysis against all seven patents before commercialising new product configurations, particularly those incorporating optical inspection, servo motion control, or automated fill logic.

What this case signals for the food processing equipment IP landscape
A seven-patent Federal Circuit split rarely closes cleanly. Here is what IP professionals in food automation need to track.
Multi-patent appeals at the Federal Circuit rarely produce clean outcomes
When appellants assert seven patents spanning distinct product categories, split decisions are statistically common. Each patent family can rise or fall on independent claim construction or obviousness grounds. IP teams monitoring this space should map which specific patents drove the reversal — that granularity determines real enforcement exposure.
Remands extend litigation timelines — budget and monitor accordingly
An ‘affirmed-in-part, reversed-in-part, and remanded’ verdict effectively restarts district court proceedings on the reversed issues. For Provisur and any third parties designing around these patents, the remand phase may take another one to three years to resolve, prolonging commercial uncertainty across the affected product lines.
Weber v Provisur — key questions answered
The Federal Circuit issued an ‘affirmed-in-part, reversed-in-part, and remanded’ decision on October 2, 2024. The court upheld some aspects of the lower court’s ruling, reversed others, and sent the reversed issues back to the district court. Part of the appeal was also dismissed. No single party achieved a complete appellate win.
Seven U.S. patents were asserted: US8322537B2, US6669005B2, US9399531B2, US6320141B1, US6997089B2, US7065936B2, and US7533513B2. They cover fill-and-pack apparatus and methods, optical grading for slicers, servo-controlled conveyors, sheet interleavers, and yield monitoring systems used in industrial food slicing operations.
It means the Federal Circuit found no reversible error in some lower court findings (affirmed) and found legal error in others (reversed). The reversed issues are sent back to the district court for further proceedings under the appellate court’s corrected legal framework. Both parties have partial wins and partial losses, and the case continues at the district level.
The Federal Circuit dismissed part of the appeal alongside its merits ruling. This typically suggests that one or more issues were mooted, that a party withdrew certain claims, or that the court lacked jurisdiction over a specific aspect of the appeal. The public record does not specify which patents or claims were subject to the partial dismissal.
The partial reversal confirms Weber’s patent portfolio retains enforceability on at least some claims, creating continued IP risk for manufacturers of servo conveyors, optical graders, sheet interleavers, and yield monitoring systems. The remand extends litigation uncertainty. Competitors and component suppliers operating in this space should conduct freedom-to-operate analysis against all seven asserted patents before launching new products.
