Narrative Opinion Summary
This case involves a dispute between LTJ Enterprises, Inc., a Minnesota corporation owning a patent for a bin level indicator, and Custom Marketing Co. LLC (CMC), a North Dakota company, over alleged patent and trademark infringement. LTJ claims that CMC’s product, Grain Gauge, infringes on its patent and that CMC engaged in unfair competition and trademark infringement. CMC denied these allegations and counterclaimed for tortious interference and violations under Minnesota's Agricultural Equipment Farm Dealership Act (MAEDA). The court held oral arguments on motions for summary judgment and to exclude expert testimony from both parties. LTJ’s patent infringement claims, based on literal and equivalent infringement theories, were denied as the accused product did not meet the patent limitations. CMC's motion for summary judgment was granted as there was no evidence of patent infringement or likelihood of confusion regarding trademark use. The court also dismissed CMC's counterclaims under MAEDA due to the lack of a dealership agreement and the classification of LTJ as a farm equipment manufacturer. Both parties' motions to exclude expert testimony were denied. The case highlights the application of patent and trademark law principles, including infringement analysis and the standards for summary judgment and expert testimony admissibility.
Legal Issues Addressed

Application: Both parties' motions to exclude expert testimony were denied as the experts were deemed qualified and their methodologies reliable.
Reasoning: According to Federal Rule of Evidence 702, expert testimony is admissible if the expert is qualified, the testimony assists the fact-finder, is based on sufficient data, employs reliable methods, and applies those methods to the case facts reliably.
Minnesota Agricultural Equipment Farm Dealership Act (MAEDA)subscribe to see similar legal issues
Application: CMC's MAEDA claim was dismissed as LTJ was not classified as a farm equipment manufacturer, and LevAlert did not qualify as farm equipment.
Reasoning: Consequently, LevAlert is not considered farm equipment, and therefore, LTJ cannot be classified as a farm equipment manufacturer, leading to the dismissal of CMC's MAEDA claim.
Patent Infringement: Literal and Doctrine of Equivalentssubscribe to see similar legal issues
Application: The court examined whether the Grain Gauge infringed on LTJ's patent claims literally or under the doctrine of equivalents, ultimately finding no infringement.
Reasoning: The large gear cannot be considered literally or equivalently an arm, as it does not fulfill the requirement of being 'connected' to the actuator means specified in Claim 18 of the patent.

Application: Summary judgment was granted in part for CMC, as there were no genuine issues of material fact regarding non-infringement of the ’927 Patent.
