Description
"This book shows readers how to file a provisional patent application (PPA), and mark the invention with 'patent pending.' A PPA, allows the inventor time to figure out the profitability of a creation before investing more time and money. The book covers how to write a clear PPA, conduct a patent search online and understand basic patent law." --
