- JoeAltmaier 6y agoSomebody owns those patents...
- Scarblac 6y agoPatents are only valid for 15 years or so.
- willis936 6y agoThat’s the idea. I have no clue what’s going on with big companies sitting on stacks of tens of thousands of patents and litigating people for violating patents unrelated to what the company produces.
- JoeAltmaier 6y agoAh yes, when he filed the limit was 17 years. I had some notion they could be renewed. I guess I was thinking of copyright.
- dangerbird2 6y agopatents expire after 20 years
- progre 6y agoPatents expire. That's the point of patents. Instead of complete secrecy thats practically impossible to maintain we have a system where patented inventions are publicly disclosed and the inventor gets to have sole use of the invention for a limited time.
