Marvell Agreed to Buy Lumentum for $115B. Nobody Said "Patent."

About this episode

Marvell agreed to acquire Lumentum in an all-stock deal with a $115 billion implied enterprise value. I read the press release and the analyst call transcript. The word "patent" doesn't appear once. So what exactly is Marvell buying? Lumentum makes the lasers and optical parts that move data through fiber inside AI data centers. Marvell designs the chips, but it doesn't own fabs. Seth Cronin takes the deal apart: how both companies were assembled through acquisitions, why Marvell wants Lumentum now, the indium phosphide fabs Lumentum's CEO called a crown jewel, the terms, and what the filings actually say about the IP. Then why Lumentum's IP strategy was so well executed: it invented, acquired, built know-how that's hard to copy and locked in customers, all at once, with patents wrapped around the process secrets. Plus a smaller deal with the same pattern (NIL Technology), and a Patent of the Week from Lumentum. Prefer to read?
