I'll get a patent application template in .txt, .doc, and .wpd formats linked to this page as quick as I can. What I always advise though is DO NOT purchase software expecting it to "do the work" for you. It won't. All it will do is format the text it asks you to write and put in the required headings! It won't do the drawings and, from what I've heard, the ones that "promise" to write the claims for you FAIL MISERABLY at "writing" anything that will give you useful protection. Some software can help you organize your thoughts and that might provide some people some benefit worth the purchase price in that regard. My strong bias is that you'll be a lot better off investing 40 or 80 hours, maybe more, maybe less, downloading from the www.uspto.gov web site 25 or 50 or 100 recent patents in the field of your invention then read carefully through them both for understanding technically what they say and for understanding how they have been worded to adequately, broadly, and narrowly meet the legal requirements for "enabling one of ordinary skill in the art" to make and/or use the described invention "without undue experimentation."
