The talk will cover practical guidance on patents and registered designs for hardware and electronics, from PCB layouts and custom silicon/IC designs through to embedded algorithms and physical enclosures. This includes advice on the value of a patent or design for the latest technologies, including how to broadly protect a specific circuit or chip architecture, and trade-offs between trade secrets and patents for advanced fabrication processes. A discussion on the possibility of protecting software, including AI and other algorithms, will touch on common misconceptions and tips for what may be patentable. High levels of package integration, particularly with xPUs and stacked memory dies in a 3D package offer a plethora of opportunities for protecting various hardware, interconnect, chip architecture and package configurations as well as the methods of operating such advanced devices, and the talk will provide some guidance on how even small changes to a semiconductor package may yield patentable subject matter. The role of registered designs, which may offer complimentary protection to patents will be discussed particularly in the context of protecting the appearance of visually aesthetic hardware and software.
