This was invented 48 years ago; would relevant patents have expired by now? What would prevent other companies from also manufacturing this glass?

- Zaak 16y agoTrade secrets most likely. It would be cloned eventually, but Corning would have a lock on the market while other companies did their R&D.
- stuff4ben 16y agoprobably nothing. But to get to market when your competitor has 48 years on you and has the ability to ramp up production extremely quickly kind of takes the wind out of your sails if you know what I mean.
- janzer 16y ago"...Corning dug out Chemcor from its database, tweaked it for manufacturing in LCD tanks, and renamed it Gorilla." My guess is that "tweaking" is covered by new patents, although anyone should be able to produce the original Chemcor now.
- ajdecon 16y agoExactly. In particular, it sounds like they've revamped the manufacturing process a bit to take advantage of modern techniques. This new process will probably be the new patent, rather than the glass formula.
