Quite difficult to research things without using a 'online' Search Engine. Search Engines are not a one way knowledge system. Anyone that thinks Google/Baidu/Bing don't scrap search queries for Intellectual IP ideas is deluded, especially when they have targeted IP addresses of individuals knowing to work in the Intellectual IP industry.
You just have to look at the way Google handles its interview process with such individuals. Google use the word 'interview' (interviews) as a means to gather competitive data.
The UK's Investigatory Powers Bill just makes this even worse, because now you can't tell who is doing the targeting, with free reign to penetrate networks.
I'd be blaming Google long before I blamed the Chinese.
