Narrative Opinion Summary
The case involves a dispute over Patent No. 1,930,987, concerning a method and apparatus for testing geological formations in deep wells. The plaintiffs, including Honolulu Oil Corporation, alleged infringement by Halliburton and others. The district court initially invalidated both the method and apparatus claims of the patent, a decision later reversed by the Ninth Circuit Court of Appeals. However, the Supreme Court reviewed the case and upheld the invalidity of the patent claims. The court found that prior art, particularly the Franklin Patent No. 263,330, anticipated the patent claims, demonstrating that the claimed method and apparatus lacked novelty. The court ruled that the defendants' devices did not infringe the patent, as they did not embody the purported innovations claimed. The judgment highlighted the requirement for true invention in patent claims, noting that the method claims were essentially similar to established techniques and the apparatus claims did not constitute new inventions. Consequently, the Supreme Court reversed the circuit court's decree for the defendants' petition and affirmed the district court's finding of invalidity, thus ruling in favor of the defendants.
