The Patent Tape

This draft treats a patent record as an early technical signal, not as proof of product timing or customer demand. The record surfaced through PatentBear is Co-packaged light engine chiplets on switch substrate, published or issued on 2021-11-16. The canonical PatentBear record is https://www.patentbear.com/patents/US11178473B1.

Why It Matters

The patent signal is that optical engines are becoming part of the switch substrate conversation. That pulls networking coverage toward packaging, substrate reliability, and heat removal.
