So the key timeline is that constructive notice kicks in July 1, 2022, even though the period from January through June only shows 60% compliance. The October email doesn't count as actual notice, and the February 2023 letter comes too late to matter since constructive notice was already established. Looking at the six-year lookback from the June 2026 filing date, that pushes the damages window back to June 1, 2020, which is before the patent issued.
