Sally Pipes(@sallypipes):Kudos to @Council4IP's @StewartCoke on such a great piece. Claims about "patent thickets" and "evergreening" are misleading. A new patent doesn't extend an old one. When the original expires, generics can copy that version. Newer patents protect improvements that help patients.
