#Standards (Wi-Fi, 5G…) make products interoperable—but they can also create lock-in. That’s where #SEP & #FRAND come in: bargaining shifts from ex-ante competition to ex-post leverage.

🤓 New on The Patentist: Patent rights and cumulative innovation: Part II

🔎 Patent citations are everywhere in innovation research. But do they really trace how ideas spill over between inventors—or are we mistaking legal paperwork for knowledge flows? 🧐

Do more citations mean better patents? What patent citations really measure

🔎 Do more #patent citations mean better inventions?

A widely used metric in #innovation studies—but not always well understood. My new post on #ThePatentist reviews the evidence, from expert ratings and market prices to auction data and hybrid corn yields.

Spoiler: Stronger ≠ better.
