Patent terms run from the filing date, not from the date the product actually launches. That fact gets ignored constantly in product planning, and the result is companies filing early, taking years to bring the product to market, and burning through a meaningful chunk of the patent's useful commercial life before a single unit ever sells.
Filing Timing Should Be a Commercial Decision
I now coordinate patent filing timing directly with the realistic product launch timeline, rather than filing the moment an invention is developed regardless of how far out commercialization actually is. Filing too early on a product that's genuinely years from market erodes the enforceable window unnecessarily. Filing too late risks a competitor beating you to the patent office on a similar innovation. The right filing window is calibrated to a realistic, not aspirational, commercialization timeline.
Provisional patent applications give useful flexibility here, buying a year of protected development time before committing to the more expensive and legally binding utility filing, and I use that year deliberately to firm up the commercialization plan rather than just letting it pass by default.
Track the Clock Actively, Not Passively
I now maintain an active dashboard tracking every core patent's filing date against its projected commercial launch date, flagging any patent where the gap has grown large enough that the remaining enforceable window after launch is getting uncomfortably short. That visibility forces conversations earlier: either accelerate the development timeline, adjust the commercialization scope to something achievable sooner, or accept that the patent's practical commercial value has been meaningfully reduced by the delay.
Patents aren't static assets sitting in a drawer gaining value over time. They're depreciating assets from the day they're filed, and the only way to capture their full value is to compress the gap between filing and genuine commercial launch as much as the business realistically allows.
