Hi, I have two sentences that are rather long, and I feel that a comma would be appropriate to clarify which part of the sentence belongs to which subject.
"He also responds to those critics who argue that life materials are mere discoveries of nature and cannot therefore be patented, by blurring the distinction between discovery and invention."
"He also deals with criticisms levied against corporations who use patent laws to their own advantage to increase the costs of diagnostic tests, by reiterating that no such tests could even exist if the technology had not first been invented and patented."Are these acceptable uses of the comma? Or are they comma splices? Thanks for your help!
