BOOK — VOLUME 2 PREVIEW
Cage Patents — Nine Forms of “Lock-it-in” Design Excavated by AI Archaeology
Releasing June 2026 ・ Indicative price ~$15 ・ ~250 pages, A5
Across the 100 episodes of AI Archaeology Phase 1 (May 1–8, 2026), one design philosophy kept showing up: lock something inside, then make it useful. Electrons, charges, photons, molecules, ions, heat — caged by physical structure. And pure software — caged by judicial doctrine, contracts, or deliberate non-patenting. Volume 2 walks through all nine forms via Claim 1 verbatim, tracing the lineage from old patents to today's LLMs, SSDs, EV batteries, and sustained-release cosmetics.
The nine forms
FORM #1
Electron cage (floating gate)
Masuoka 1980, US4531203A — Flash memory
Floating gate plus control gate separated by oxide; tunneling electrons in and out. The cage that holds your SSD bits.
FORM #2
Charge cage (1T1C DRAM)
Dennard 1968, US3387286 — DRAM
One transistor, one capacitor. Hold the charge, refresh it before it leaks.
FORM #3
Photon cage (resonator / QD)
Bell Labs semiconductor laser patents
Trap light in a resonator to drive stimulated emission. Roots of every laser diode and quantum dot LED.
FORM #4
Molecular cage (clathrate / cyclodextrin)
Sustained-release cosmetic and pharma patents
A host molecule cages a guest, releasing it slowly. The reason your skincare actually does something for hours.
FORM #5
Ion cage (Li-ion intercalation)
Goodenough 1980s, LiCoO₂ patents
Layered structure that reversibly hosts lithium ions. The reason EVs and laptops happened.
FORM #6
Thermal cage (insulating package)
MEMS and IC package thermal isolation patents
Physically separate the heat source from the cool side. The unsung hero of every smart sensor.
FORM #7
Logic cage 1: pre-judicial era
Backus 1957, FORTRAN — never patented
Before the 1972 Gottschalk v. Benson ruling, pure software wasn't patentable. IBM caged its know-how through manuals released first, then code distributed for free.
FORM #8
Logic cage 2: unsettled era
Atkinson 1985, HyperCard — never patented
Between Diamond v. Diehr (1981) and State Street Bank (1998), eligibility was murky. Apple caged HyperCard through a 'bundled-free' contract with Atkinson, not a patent.
FORM #9
Logic cage 3: forced/voluntary openness
BBN IMP 1969 / Xerox PARC Smalltalk 1972
ARPA contract terms forced public release. Xerox chose unrestricted redistribution. By choosing not to patent, both caged a design specification inside the industry's shared vocabulary.
Who this is for
- Engineers and investors in semiconductors, AI, EVs, and materials
- People who read patent doctrine as technical history
- Anyone who wants to back-derive today's bottlenecks from old Claim 1s
- Readers who've been following the AI Archaeology series and want a curated cut
