To me this is the fundamental problem with the notion of intellectual property and its protection: so much of it is trade secret and undocumented (let's be real, we disclose as little in patents as we can get away with). Companies come and go, and in the process, institutional knowledge of how to do things is lost because there is no incentive to make it public for others to replicate. This also means that once lost, it must be rediscovered later.
This is why open source software is stronger than ever despite its shortcomings and efforts of large orgs to kill it. Rather than bending backwards and treating it like property (as originally demanded by Bill Gates in his open letter decades ago, we did the right thing and treated it like knowledge (e.g. like mathematics).
Intellectual property was a horrible flawed idea that the world will continue to pay for dearly for decades after it is finally discarded.
