How long is a "long time ago"? because every patent has a term and
here it may have expired.

On the decision/sorting out side, for this and for any other patent
issue, do we document already (in source code or a separate file) the
reasons to activate or not pieces of a software (or to exclude them
from packages), because of some patents?
List of questions to check would be at least:
- what is exactly covered by what patent (reference, registration,
territory/ies for which it has been registered)?
- where is it implemented exactly in the source code? (
- who owns this patent?
- did the patent holder announce his clear intention upon it? (that
is, is he using it to control/restrain use or not? *)
- are there obvious prior art that could make this patent obviously invalid?
- what is decided and when (and what may change the decision, later)?
- what would be alternative ways to implement the function (if the
patent does not just cover the function, but a specific implementation
* one does not necessarily register a patent to be offensive with it;
here, we knew about iPix, what about the new holder?
Btw, a draft policy for patents management was discussed among
founders and other people (lawyers) months ago and a tentative summary
written by me here:
