Is can follow a different pattern.

Is is is?

"Is is is?" is "Is is is?"

"'Is is is?' is 'Is is is?'" is 'Is is is?' is 'Is is is?'"

"'"Is is is?" is "Is is is?"' is '"Is is is?" is "Is is is?"' is '"Is is is?" is "Is is is?"' is '"Is is is?" is "Is is is?"'"

etc.

(Note that parsing grammatically correct English sentences is an NP hard problem.)
