The Phoenix-based equipment dealer reviews competing patent complaints and explains why equipment buyers should distinguish legal allegations from decisions affecting specific products.

PHOENIX, AZ — Badger Bluff Machinery Sales is highlighting patent proceedings involving Caterpillar and Doosan Bobcat as an industry development relevant to construction equipment buyers. The dispute has resulted in separate investigations by the U.S. International Trade Commission (ITC) concerning alleged infringement involving imported machinery and components.

As a supplier of pre-owned Caterpillar and Bobcat equipment, the dealership follows developments involving both manufacturers while maintaining its focus on equipment condition, suitability, and customer support.

Two Complaints Lead to Separate Investigations

Doosan Bobcat North America filed an ITC complaint against Caterpillar on December 2, 2025. On January 2, 2026, the Commission announced an investigation covering certain skid-steer loaders, compact track loaders, excavators, wheel loaders, dozers, and components.

Bobcat requested a limited exclusion order and a cease-and-desist order. In announcing the investigation, the ITC expressly stated that opening the proceeding did not represent a decision on the merits of the allegations.

Caterpillar filed its own ITC complaint on May 26, 2026, followed by a supplement on June 11. On June 26, the Commission announced a separate investigation into certain heavy machinery and components, naming several Doosan Bobcat entities as respondents.

Caterpillar also requested a limited exclusion order and cease-and-desist orders. The Commission again emphasized that initiating the investigation was not a finding of infringement.

Requested Restrictions Are Not Final Decisions

The distinction between a complaint, an investigation, and a final determination is central to understanding the dispute. Both manufacturers have asked the Commission to impose restrictions, but those requests should not be presented as restrictions already granted.

The ITC’s announcements describe proceedings in which an administrative law judge examines the evidence and makes an initial determination, subject to Commission review. Any assessment of the consequences for particular equipment must therefore consider the scope and outcome of the relevant proceeding.

For buyers, the practical approach is to examine any subsequent decisions carefully rather than assume that every machine carrying either brand is affected.

Keeping Equipment Purchases Focused on Practical Needs

Badger Bluff Machinery Sales encourages customers to evaluate individual machines based on their intended applications, condition, specifications, service requirements, and total purchase costs.

The company provides equipment information, photographs, walk-around videos, and serial numbers to help buyers assess available inventory. Its team also assists with equipment selection and transportation arrangements for customers purchasing from outside Arizona.

The dealership reported selling more than 460 pre-owned machines during the first half of 2026, including equipment from Caterpillar, Bobcat, and other established manufacturers.

While manufacturer disputes attract industry attention, the company’s purchasing guidance remains centered on helping customers understand the equipment they are considering and the support available after delivery.
