I was talking about backbone routing hardware. Wireless technology is a non-sequitur, and I’m not an expert so cannot comment. Ultimately, the parent was asking for example of “large” examples of IP theft, and this should surely count. I can attempt to respond to some of your 5G comments. My outsider perspective is that many countries have the resources to develop this technology, and my guess is differences in timing are dominated by capital efficiency questions and not talent. Differences in cost probably come down to policy and subsidy regimes — and free appropriation of IP is only one of many kinds of subsidies a government can provide domestic firms.
