Innovator’s Patent Agreement ⇥

Marco Arment has some sharp words regarding Twitter’s IPA:

First, it’s interesting to read their definition of “a Defensive Purpose”, [… which leaves] a lot of room for interpretation.

Arment has some good points here. I’m not sure if Twitter’s intent was to be vague, and if it wasn’t, their position should be clarified and loopholes should be removed. I suspect they wanted some room for negotiations and legal purposes, though.
