Caterpillar and rival Doosan Bobcat have opened new lawsuits in Texas federal court, with each company accusing the other of infringing several patents related to improving earthmoving machinery. The companies have been locked in a legal battle over compact construction equipment technology.

Why it matters

This escalating patent dispute between two major construction equipment manufacturers highlights the fierce competition and high stakes in the industry, where innovations in machinery can provide a significant competitive advantage.

The details

Caterpillar brought the counterclaims in response to patent lawsuits filed by Bobcat last year over the companies' construction equipment. Caterpillar has separately denied those allegations, stating it has a right to protect its intellectual property. Bobcat, which specializes in compact construction equipment, claims Caterpillar copied its "skid-steer loader" technology. Caterpillar responded that Bobcat's loaders and excavators infringe its patents, and that Bobcat studied and copied its technology as part of a "competitive intelligence" program.

  • Bobcat filed patent lawsuits against Caterpillar last year.
  • Caterpillar filed its countersuit claims on April 7, 2026.
