In the case of Dyke et al. v. Taylor Implement Manufacturing Co., Inc., 1967, the Supreme Court ruled on a matter concerning patent infringement and antitrust laws. The plaintiffs, Dyke and his associates, had developed an innovative grain dryer which they patented and sold through their company Agridry Corporation. They alleged that Taylor Implement Manufacturing Company infringed upon this patent by producing similar dryers without permission or licensing agreements in place. The court found that while there was indeed evidence of patent infringement by Taylor Implement Manufacturing Co., it did not constitute monopolistic practices under antitrust law as claimed by Dyke et al.. This is because the defendant's actions did not result in controlling prices or eliminating competition within the market for grain dryers. Furthermore, it was determined that even if such monopolistic behavior were present, it would be protected under federal law due to its association with a validly obtained patent right - unless misuse could be proven beyond reasonable doubt. Therefore, although acknowledging some level of wrongdoing on part of Taylor Implement Mfg. Co., the Supreme Court ultimately ruled against Dyke et al.'s claim for damages related to anti-competitive conduct.

In the dissenting opinion for Dyke et al. v. Taylor Implement Manufacturing Co., Inc., it was argued that the majority's decision to uphold a Minnesota law prohibiting out-of-state corporations from removing cases to federal court, even when diversity jurisdiction exists, undermines the purpose of diversity jurisdiction itself - which is to prevent potential bias against out-of-state parties in state courts. The dissenters contended that this ruling effectively allows states to dictate federal jurisdiction rules and could potentially lead other states to enact similar laws limiting access of non-resident defendants to federal courts. They also expressed concern about how such restrictions might impact interstate commerce and business relationships between companies operating across different states.
