What is patentable?
Only inventions are patentable. An invention must be new, useful and must involve inventive steps compared to closest prior art. A new and unobvious product, process, apparatus or composition of matter will generally be patentable.
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.
Information required for conducting search:
To conduct a search the description, drawings or photographs of the invention, showing how it is made, operated and used would be helpful. Further details of any known prior art; a summary of the prior art's shortcomings; an explanation of how these are overcome by the invention; a list of any other advantages of the invention; and, details of any possible variants or modifications that could be made without departing from the general concept of the invention
