- Subject Matter: This appeal sought to reverse and/or to set aside a Federal Court judgment and to declare certain claims of patents 2,965,426 and 2,992,233 valid and infringed. The appeal alleged that the trial judge erred in applying the law of obviousness by performing a classic hindsight analysis, erred in attributing the burden of proving inventiveness, erred in reproaching the inventor for not opening the PolarFlex product or conducting a literature search, erred by excluding relevant case law teachings in her analysis, and erred in characterizing the disputed claims based on whether the patents did or did not constitute "combination patents." This case is ongoing.

- Date: The hearing was set on Dec. 10, 2024.

- Venue: This was a federal case before the Federal Court of Appeal.

- Amount: No financial award was specified.
