Cisco's US challenge to Ramot at Tel Aviv University patent partly succeeds

( November 12, 2024, 10:10 GMT | Official Statement) -- MLex Summary: Cisco Systems has prevailed, in part, on allegations a patent for converting digital data into modulated signals is indefinite. US District Judge Gregory B.
