Here are some of the things invented by the ancient Greeks that have modern day patents:
Ironically "Trial by jury" (no current patents, just threw it in)
This post was put together in about 10 minutes. Most inventions have been around a long time and always get improved with better ideas and implimented differently with different uses and needs. SFOR's patents show what existed prior to their patents being granted followed by reveiwed then followed by PTAB denial of IPR. The PTO has been up this road 3 times now with these patents.
Anyone who reads SFOR's patents can see what they improved on from prior patents (that are valid) to make COBAS a better product, "true OOBA".
SFOR created a better "door lock" to help keep hackers out. This is what must be appealed by R&G.
ACS used the same technology to create Cygate. That alone explains the better lock concept that is patented by SFOR.
