The implications for B2B contracts are significant here. In construction, for example, subcontractor agreements often reference separate terms documents that get updated independently. If email notice plus continued use constitutes acceptance, it changes the calculus for how companies manage contract amendments across multi-party project teams. The practical challenge is that on a large project you might have 50+ subcontractors who all need to actively acknowledge revised terms, and this ruling suggests passive acknowledgment through continued use may suffice.
