Narrative Opinion Summary
This case involves a dispute over the alleged patent infringement by defendants Broetje Automation-USA Inc. and Brotje-Automation GMBH concerning U.S. Patents 5,011,339 and 5,143,216. Plaintiffs Ateliers de la Haute-Garonne and F2C2 Systems sought partial summary judgment to invalidate certain defenses raised by the defendants, claiming they were untimely. The court found that the indefiniteness defense was timely as it arose naturally from depositions. The lawsuit, initially filed in California but later transferred, had its patents invalidated for failure to disclose the best mode, a decision which was reversed on appeal. Plaintiffs argued that the claim term 'peripherally guiding' was not indefinite, but the court denied their motion for summary judgment, concluding that the term might lack a precise meaning based on inventor testimony. As the indefiniteness issue involves factual disputes regarding the understanding of the claim term by one skilled in the art, the court decided the matter will proceed to trial. The burden remains on the defendants to demonstrate the claim's invalidity by clear and convincing evidence, with the ambiguity favoring the non-movant at this stage.
