In the case of Koehring Co. v. Hyde Construction Co., Inc., et al, 1965, the Supreme Court dealt with a dispute over patent infringement and antitrust laws. The plaintiff, Koehring Company alleged that Hyde Construction had infringed on its patent for a concrete mixing machine and sought damages for this violation. In response to these allegations, Hyde claimed that Koehring's patents were invalid due to misuse in violation of antitrust laws as they had been used to monopolize trade and commerce among several states. The court ruled in favor of Hyde stating that there was sufficient evidence showing that Koehring engaged in illegal tying arrangements which violated antitrust law by forcing customers who leased their patented machines to also buy unpatented parts from them exclusively. This ruling established an important precedent regarding the intersection between intellectual property rights and competition law - indicating clearly that while patents give inventors exclusive rights over their inventions, they cannot be used as tools for anti-competitive practices.

The dissenting opinion in the case of Koehring Co. v. Hyde Construction Co., Inc., argued that the majority's decision to uphold a jury verdict for damages based on an alleged breach of warranty was incorrect and should be reversed. The dissent contended that there was no evidence presented at trial to support a finding of any express or implied warranty by Koehring, nor any proof that such a warranty had been breached. Furthermore, it pointed out inconsistencies in the plaintiff’s claims about when they discovered the defect and their subsequent actions which did not align with someone who believed they were sold faulty equipment under false pretenses. It also criticized the majority for ignoring established legal principles regarding warranties and damages, arguing this would create confusion and uncertainty in commercial law.
