This is a follow up from this discussion. I am a patent attorney and some standard sentences that we use include this:
The above-recited and other advantages and features of the disclosure will become apparent by reference to specific embodiments thereof which are illustrated in the appended drawings."
I assume a comma should be placed before which, but I am wondering if you could help me understand if it is required or optional?
Also, another sentence I came across goes like this:
Device A sends data to device B which then forwards the data to device C.
Microsoft Word always complains, seeing it as a restrictive clause and demands a comma or changing which to that. Am I correct in not having a comma?
