Recent chatter about IP security / reverse engineering technology - theft of corporate secrets and material process....
Understanding Patents and security in 2021 going forward is key to understanding market segment and operability in that market...
Physically Unclonable Function - Root of Trust ...its not locking up patents in a filing cabinet that keeps your products safe
its programmed into the SoC and active at every operational level of that system..
when was the last time your phone was hacked? yet the most mobile easily accessible device on the planet -
no one has reverse engineered Apples' M1 chip for these reasons 
and iots the fastest out there at the moment !...getting rave reviews..
'NeoPUF, which was developed by eMemory Technology, uses differences in the tunneling effect of an oxide layer to achieve PUF characteristics (Hamming weight 50%; Inter-Hamming Distance 50%; Intra-Hamming Distance 0%), which fits the aforementioned randomness, uniqueness and stability conditions of a reliable PUF. The conditions mentioned have been verified during the manufacturing process of major foundries. The inherent PUF features of a chip can be used to store a key required for a root of trust. Furthermore, it can also be used as a unique identification code (UID). The security features of the startup process are used to verify the integrity of a chip. Due to its high stability and reliability, NeoPUF also has an immediate startup time. At startup, a PUF random number can be used to store a key without any delays. As a result, NeoPUF can provide a base of trust to support startup security protection as well as hardware and software verification to effectively improve the security of the chip.'
Great reading to put to bed the misconceptions of Patent / chip security
