Patentability search is a search for invention in hope of not finding the invention. The patentability search is an universal concept since inventions cannot be boundary constraint. But it is to be noted that the patent laws are territorial.
Computer databases search is quick and relatively inexpensively. Database searches are most useful in searching sophisticated inventions, which can be described by precise, well-known terms of art. They are much less useful in searching mechanical gadget type inventions. No search will “guarantee” the patentability of any invention.
The object is to make a reasonable assessment of the prospects for obtaining worthwhile patent protection. Search results are also useful in preparing a patent application.
Patent is a statutory right for an invention granted for a limited period of time to the patentee by the Government, in exchange of full disclosure of his invention for excluding others, from making, using, selling, importing the patented product or process for producing that product for those purposes without his consent.
A patentee must disclose the invention in a patent document for anyone to practice it after the expiry of the patent or practice it with the consent of the patent holder during the life of the patent.
