Take the first step to protecting your invention! Ready to stamp "patent pending" on your invention? Then you need to file a provisional patent application (PPA), an inexpensive way to claim your hard work. With a PPA, you'll have time to figure out whether you can make a profit from your creation before you invest more time and money. With Patent Pending in 24 Hours, you have all the forms and information you need to get the job done! Find out how to evaluate hurdles to patentability, write a clear PPA, prepare informal drawings of your invention, conduct a patent search online, understand basic patent law, complete all forms required by the U.S. Patent and Trademark Office, file your application and modify your invention after filing. The book also includes important legal forms to help you preserve your rights when showing or selling your invention, including: nondisclosure agreement, patent assignment, prototype-maker agreement and joint-ownership agreement. The 4th edition is completely revised with updated case law and patent regulations, updated filing information and new application examples.
