TEN TIPS ON PATENTS
Every category and type of document has characteristics that are different from other types of documents. Patents are no exception. In fact, I find more interesting facts associated with patents than with any other category of documents. Every country has different rules concerning its patents. Every library which maintains a collection of patents has different guidelines for access and availability. The list is endless.
The facts that follow are a few common observations about U.S. and Japanese patents. Hopefully, the information will shed some light on some of the many mysteries about patents. 1. U.S. patents are of three types: * Utility Patents are patents issued to cover a new product, invention, or technology.

File wrappers contain all the paper work and cited art that pertained to the issuing of the patent. 5. International Technology Disclosures (ITD) serve to provide maximum protection when used in lieu of filing a patent application. Publishing an invention in ITD provides a more prompt way of initially securing intellectual property than the process of filing a patent application. …
