As someone who has dealt with this I suggest you figure out a way to avoid the patent. Read through the claims, figure out what combination of features they have patented and then change your product to avoid those features in that combination. You likely can either do something more advanced or something less advanced -- if you have the choice do the more advanced solution as you are then likely pushing your product…
The parent’s advice assumes the players are reasonable people acting in good faith. In the case of patent trolls, they are often not acting in good faith. Most of the allegations are not good faith interpretations of the patent. There is no “perception of infringement” to begin with. They just want a quick payout and found a cost-efficient way to state a claim against a widely used technology so that they can threaten and file lawsuits in volume. Instead, find a good patent lawyer or a pro bono resource (like EFF or a colleague with experience) that can give you resources or advice to quickly dispose of it cheaply (or even for free), if you cannot afford fight it. Sometimes, it can even be cheaper to hire an excellent patent lawyer that can win the case early than it would be to pay off the patent troll. I have written many a response to a patent licensing demand letter, knowing exactly what to say for much less than settling, where they disappear and never sue. And if they have sued, sometimes they disappear as soon as lawyers they do not want to be up against show up in the case.
In the instance of a good faith claim by a patent owner (even if wrong), there will be enough money at stake that it would be worth the cost to consult a good patent lawyer before doing a single thing.
