No. Atari did not have a patent on that port, it predated Atari. If they had a patent, Atari wouldn't hesitate to sue almost anyone. There was no lawsuit against rival computer, console or peripheral manufacturers using that port. Sega paid because they infringed on a patent for scrolling and other arcade related patents.
