Foreword I am indebted to several people who contributed by reviewing this document, teaching me some LATEX tricks and especially teaching me about patents. Let me say ahead of time that if I ignored or incorrectly dealt with their review comments, or have any remaining errors in documentation or LATEX code, the errors are solely my responsibility: I have worked with Gordon Kessler, previously our in-house patent counsel, for over ten years. He taught me almost everything I know about patents and is the patent attorney of record on many of my patents. Since I've worked with Gordon for so long, the style I use mostly re􀀍ects his. Andrew Dommer of Fish & Richardson P. C. reviewed this document and provided lots of comment
