Sorry, I have to disagree. The "window" is saying that if an inventor had disclosed information before filing, but still filed within a grace period, even if someone else filled ahead of them, they may still get protection. If they wait a long time and someone else filed, they are SOL. So it's exactly the opposite of what you describe. Old prior art, in the first to invent sense, is no longer a defense from patent suit.Sorry for digging up a week + old post, but this is categorically false. The "First to File" clause only has a 1 year grace period. That means that the "First to file" only applies if the Prior Art was disclosed a year or less before the filing date, and that disclosure was either made by the inventor or was made by someone who had access to the inventor's material.
If you base your invention on technology that is years or decades old, Prior Art still stands as a legitimate defense. If you need a case example of this, Apple lost a lawsuit against Samsung just last month because of Prior Art.

Here's the specific ruling...
And this is where Evolv is going to lose their case. Prior Art existed. All Evolv "invented" was a digital voltage regulator. Similar systems have been in use in other devices since the 1980s. A very simple example would be a digital light dimmer where you can select the specific wattage a light bulb receives to achieve a desired brightness. Many of them have a user interface that is nearly identical to Evolv's and the functionality is almost identical as well. This becomes obvious when you consider that none of Evolv's chips are actually designed and manufactured by Evolve. They used pre-existing off the shelf components to make their voltage regulators and simply wrote the software interface and algorithm to make it work the way they wanted. Their solution to regulate the power output of an ecig mod was obvious.
It's going to be hard for Evolv to convince a court that this:

Is in no way related to or based off this:

Obviousness is very different from the first-to-invent concept of prior art that stopped being a defense against patent claim in 2013. Patents are granted "in a field." So for the obviousness claim to stick, it would have to be shown that in the electronic cigarette market, wattage adjustment was common, or at least existed, before evolve put their chips out, not that wattage adjustment existed in some other use or field.
Of course, it is possible that the judge construes the field widely, as electronics instead of as electronic cigarettes, but this seems unlikely as a) the devices are marketed and sold as electronic cigarettes, not as general electronics... you don't buy a vaporizer at radio shack. & b) the patent is explicitly in the field of electronic cigarettes.
Ultimately, it all comes down to a judges decision. A judgement call.
In the case you cite, it is right on page one that this is an appeal from 2 different courts, that came to two different decisions.
