The article might disagree. See the subsection, "The importance of tacit knowledge". OTOH, if that tacit knowledge is indeed so critical then there's less risk (e.g. regarding future investment incentives) to narrowing patent protections. OTOOH, ASML's supply chain is deep and complex, and the patent portfolio is presumably similarly diffuse, which makes it difficult to analyze or even, short of a complete patent regime overhaul, identify which patents to open up to accelerate adoption.
